Safety Notes

General Safety Rules for Pneumatic Tools
WARNUNG: Read and observe all safety warnings and instructions. Failure to follow the following safety warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.

1. Work area safety
   a)Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
   b)Do not operate the pneumatic tool in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. While working the workpiece, sparks can be created which may ignite the dust or fumes.
   c) Keep children and bystanders away from your workplace while operating the pneumatic tool. Distractions from other persons can cause you to lose control over the pneumatic tool.
2. Pneumatic tool safety
   a)Use compressed air of Quality Class 5 in accordance with DIN ISO 8573-1 and a separate maintenance unit close to the pneumatic tool. The compressed
   air supplied should be free of foreign material and moisture to protect the pneumatic tool from damage, contamination, and the formation of rust.
   b)Check the connections and the air supply lines. All maintenance units, couplers, and hoses should conform to the product specifications in terms of pressure and air volume. Too low pressure impairs the function of the pneumatic tool; too high pressure can result in material damage and personal injury. c) Protect the hoses from kinks, restrictions, solvents, and sharp edges. Keep the hoses away from heat, oil, and rotating parts. Immediately replace a damaged hose. A defective air supply line may result in a wild compressed-air hose and can cause personal injury. Raised dust or chips may cause serious eye injury.
   d)Make sure that hose clamps are always tightened firmly. Loose or damaged hose clamps may result in uncontrolled air scape.
3. Personal safety
   a)Stay alert, watch what you are doing, and use com-mon sense when operating a pneumatic tool. Do not use a pneumatic tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating a pneumatic tool may result in personal injury.
   b)Use personal protective equipment. Always wear eye protection. Protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.
   c) Prevent unintentional starting. Make sure that the pneumatic tool is switched off before connecting it to the air supply, picking it up, or carrying it. When your finger is on the On/Off switch while carrying the pneumatic tool or when connecting the pneumatic tool to the air supply while it is switched on, accidents can occur.
   d)Remove any adjustment tools before switching on the pneumatic tool. A wrench or key left attached to a rotating part of a pneumatic tool may result in personal injury.
   e)Do not overreach. Keep proper footing and balance at all times. This enables better control of the pneumatic tool in unexpected situations.
   f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. g)If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.
   h)Do not directly inhale the exhaust air. Avoid exposing the eyes to exhaust air. The pneumatic tool’s exhaust air can contain water, oil, metal particles, and debris from the compressor. This can cause damage to one’s health.
4. Pneumatic tool use and care
   a)Use the clamping devices or a vice to secure and support the workpiece. Holding the workpiece by hand or against your body will not allow for the safe operation of the pneumatic tool.
   b)Do not overload the pneumatic tool. Use the pneumatic tool intended for your work. The correct pneumatic tool will do the job better and be safer at the rate at which it is designed.
   c) Do not use a pneumatic tool that has a defective On/Off switch. A pneumatic tool that cannot be controlled with the switch is dangerous and must be repaired.
   d)Disconnect the air supply before making any adjustments, changing accessories, or placing the pneumatic tool aside. This safety measure prevents accidental starting of the pneumatic tool.
   e)Store idle pneumatic tools out of the reach of children. Do not allow persons unfamiliar with the pneumatic tool or these instructions to operate the device. Pneumatic tools are dangerous in the hands of untrained users.
   f) Maintain the pneumatic tool with care. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the pneumatic tool’s operation. Have damaged parts repaired before using the pneumatic tool? Many accidents are caused by poorly maintained pneumatic tools.
   g)Use the pneumatic tool, accessories, application tools, etc. according to these instructions. Take into consideration the working conditions and the activities to be carried out. Use of the pneumatic tool for operations different from those intended could result in hazardous situations.

Safety Warnings for Compressed-air
Nailers/Staplers
Wear safety goggles.
▶Always assume that the pneumatic tool is loaded with fasteners. Careless handling of the pneumatic tool can lead to unexpected shot actuation of fasteners and
cause injury.
▶When working, hold the pneumatic tool in such a manner that your head and body cannot be injured in case of sudden kickback due to a malfunction of the energy supply or from hard objects/locations in the workpiece.
▶Never point the pneumatic tool at yourself or at persons close by.
▶Unexpected actuation will expel a fastener, which can lead to injury.
▶Do not actuate the pneumatic tool until firmly placed against the workpiece. When the pneumatic tool is not in contact with the workpiece, the fastener can bounce away from the fastening point and overload the pneumatic tool.
Do not work on ladders or scaffolds when the actuation system “Contact actuation” is set. In particular, do not move from one fastening location to another, close boxes or enclosures, or fasten transport-securing fixtures on e.g., vehicles and wagons, via scaffolds, stairs, ladders or ladder-like constructions, such as roof battens. With this actuation system, a fastener will be discharged each time when accidentally applying the pneumatic tool while the discharge lock-off is pressed in. This can lead to injury.
▶ Observe the conditions of the job site. It is possible that fasteners can burst through thin workpieces or be deflected when working in corners or against edges, and harm persons.
Disconnect the air supply, when the fastener is jammed in the pneumatic tool. When the pneumatic tool is still connected to the power supply, it can accidentally be actuated when removing a jammed fastener.
▶Use caution when removing a jammed or stuck fastener. The system can be under tension and cause the fastener to be shot or thrust out while attempting to clear the jam.
▶Do not use this as a pneumatic tool to fasten electrical wiring. It is not suitable for fastening electrical wiring, can damage the insulation of electric cables and thus lead to electric shock and danger of fire.
▶Never use oxygen or flammable gases as the energy source for the pneumatic tool. Flammable gases are dangerous and can cause the pneumatic tool to explode.
▶Use appropriate detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to an explosion. Penetrating a water line causes property damage or may cause an electric shock.
▶The pneumatic tool may only be connected to lines, for which the maximal permissible pressure of the pneumatic tool cannot be exceeded by more than 10 %; for higher pressures, a pressure control valve (pressure reducer) with a preceding pressure-limitation valve in the compressed-air line must be installed.
Excessive pressure leads to abnormal operation or breakage of the pneumatic tool, which can lead to injury.

Assembly

Connecting the Air Supply (see figure A)
Make sure that the pressure of the compressed air system is below the maximum permitted rated pressure of the pneumatic tool. Firstly, set the air pressure to the lower value of the recommended rated pressure (see “Technical Data”).
When in doubt, check the pressure at the air inlet with a pressure gauge with the pneumatic tool switched on. For maximum performance, the values for the supply-air hose 17 (connection thread, maximum operating pressure, inner hose diameter, maximum hose length; see “Technical Data”) must be observed.
The compressed air supplied should be free of foreign material and moisture to protect the tool from damage, contamination, and the formation of rust.
All fittings, connecting lines, and hoses must be dimensioned for the pressure and the required air volume.
Avoid restrictions in the air supply, e.g., from pinching, kinking, or stretching!

Connecting the Air Supply to the Pneumatic Tool

• Empty the magazine 11. (See “Emptying the Magazine”, page 24)
  For the following work steps, a fastener can be discharged when interior parts of the pneumatic tool are not in the starting position due to repairs, maintenance, or transport.
• Connect the air connector 8 with a supply-air hose 17 equipped with an air-connection coupling 16.
• Check the proper function by placing outlet 15 or the rubber workpiece protector 1 of the pneumatic tool onto a piece of scrap wood or wood material,  and discharging once or twice.

Loading the Magazine (see figures B1–B4)
Disconnect the air supply before making any adjustments, changing accessories, or placing the pneumatic tool aside. This safety measure prevents accidental starting of the pneumatic tool.

Use only original Bosch accessories (see “Technical Data”). The precision parts of the pneumatic tool such as the magazine, the outlet, and the shot duct are matched to Bosch staples, nails and brads. Other manufacturers use other steel qualities and sizes. Using fasteners not permitted, can damage the pneumatic tool and cause injuries.
While loading the magazine, hold the pneumatic tool in such a manner that outlet 15 is not pointed at your own body or at other persons.

• Clean and lubricate the magazine slider 12 as required and make sure that magazine 11 is not dirty/soiled.
• Insert a fitting nail strip 18 in the T-slot at the end of magazine 11.
• Push the nail strip in the magazine toward the front until the last nail is positioned in front of the magazine spring 10.

Note: A lock function of the magazine slider prevents the pneumatic tool from being started with an empty magazine. The discharge lock-off cannot be
pressed in and blank firing is thus prevented.

• Press the pre-tensioned nail pusher 13 against the magazine slider 12 and at the same time, pull the magazine slider completely to the end of the magazine 11.

Note: The magazine slider must slide back with only low force (finger-pressure). A tight-running magazine slider causes the nails to be driven in at an incorrect angle.

• With the nail pusher, 13 pressed, carefully guide the magazine slider 12 toward the front until the nail pusher is over the last nail, thus pushing the nail strip in the magazine completely to the front.

Note: Do not let the magazine slider snap back without guiding it. Otherwise, the magazine slider could become damaged, and there is a danger of your fingers being caught or pinched.

Operation

Actuation systems
The pneumatic tool can be operated with two different actuation systems:

• Single actuation with safety run
  With this actuation system, the discharge lock-off 2 must first be firmly pressed against the workpiece. A fastener is not discharged until trigger 5 is pulled. Afterward, further discharging procedures can only be actuated, when the trigger and the discharge lock-off have first been set back to the starting position.
• Contact actuation
  With this actuation system, trigger 5 must be pulled first. A fastener is always discharged when the discharge lock-off 2 is firmly pressed against the workpiece while the trigger is pressed. This enables a higher working speed to be achieved.

The actuation system is set via the selector switch 6.

Starting Operation
Disconnect the air supply before making any adjustments, changing accessories, or placing the pneumatic tool aside. This safety measure prevents accidental starting of the pneumatic tool.

Working with Single Actuation (see figure C)

• Press selector switches 6 inward and at the same time pivot it to the bottom position until it engages.
  The actuation system “single actuation” is set.
• Firmly position outlet 15 or the rubber workpiece protector 1 on the workpiece until discharge lock-off 2 is pressed in completely.
• Afterward, briefly press trigger 5 and release again.
  A nail is discharged.
•  Allow the pneumatic tool to bounce back from the workpiece.
• For another driving procedure, completely lift the pneumatic tool from the workpiece and position it firmly at the next desired location.

Working with Contact Actuation (see figure D)

• Press selector switches 6 inward and at the same time pivot it to the upper position until it engages.
  The actuation system “contact actuation” is set.
• Press and hold the trigger 5.
• Firmly position outlet 15 or the rubber workpiece protector 1 on the workpiece until discharge lock-off 2 is pressed in completely.
  A nail is discharged.
• Allow the pneumatic tool to bounce back from the workpiece.
• For another driving procedure, completely lift the pneumatic tool from the workpiece and position it firmly at the next desired location.
• Move the pneumatic tool uniformly over the workpiece by lifting it off and applying it again.
  Each time when applying the pneumatic tool while the discharge lock-off is pressed in, a nail will be discharged.
• As soon as the desired amount of nails has been driven in, release trigger 5 again.

Working Advice
Disconnect the air supply before making any adjustments, changing accessories, or placing the pneumatic tool aside. This safety measure prevents accidental starting of the pneumatic tool.
Check the proper function of the safety and actuation devices, and the tight seating of all screws and nuts each time before using.
Disconnect a defective or not properly operating pneumatic tool immediately from of the air supply and contact an authorized service agent for Bosch power tools.
Do not perform any incorrect manipulations on the pneumatic tool.
Do not disassemble or block any components of the pneumatic tool, such as the discharge lock-off. Do not carry out “emergency repairs” with unsuitable means. The pneumatic tool is to be maintained regularly and properly (see “Maintenance and Cleaning”, page 25).
Avoid any weakening and damage whatsoever of the pneumatic tool, e.g., through:

• Imprinting or engraving,
• Retrofitting measures not approved by the manufacturer,
• Guiding along templates manufactured of hard material, e.g. steel,
• Dropping on or sliding over the floor,
• Using as a hammer,
• Applying any kind of force.

Make sure to check whatever is below or behind your workpiece. Do not shoot nails into walls, ceilings, or floors, when persons are behind them. The nails can burst through the workpiece and injure someone. Do not shoot a nail onto an already driven-in one. This could cause the nail to deform, the nails could become jammed or the pneumatic tool could move uncontrolled. When the pneumatic tool is used under cold ambient conditions, the first nails will be driven in slower than usual. Once the pneumatic tool has warmed up during working, normal operating speed will be regained.
Avoid blank shots in order to reduce the wear of the impact striker.
For longer work breaks or after finishing work, disconnect the pneumatic tool from the air supply and empty the magazine.

Emptying the Magazine (see figures E1 – E2)

• With the nail pusher 13 pressed, pull the magazine slider 12 to the rear until the last nail is free; then carefully guide the magazine slider toward the front to the beginning of the magazine 11.
  Note: Do not let the magazine slider snap back without guiding it. Otherwise, the magazine slider could become damaged, and there is a danger of your fingers being caught or pinched.
• Turn the pneumatic tool so that the nails in the magazine slide back to the magazine spring 10.
• Push the magazine spring down and allow the nails to slide past the nail pusher 13 out of the magazine 11.

Adjusting the Depth Stop (see figure F)
The driving depth of the nails can be set with depth stop 14.

• Empty the magazine 11.(See “Emptying the Magazine”, page 24)
• To reduce the driving depth, turn the depth stop clockwise.
  or To increase the driving depth, turn the depth stop anticlockwise.
• Refill the magazine. (See “Loading the Magazine”, page 22)
• Test the new driving depth on a test workpiece.
  Repeat the work steps as required.

Removing the Discharge Lock-off
For service or cleaning purposes, the discharge lock-off 2 can be removed.

• Turn depth stop 14 in a clockwise direction, until the first thread can be seen.
• Carry out 6 further turns in a clockwise direction.
  The discharge lock-off 2 can now be pulled off.
• To reinsert again, slide discharge lock-off 2 back into the holes intended and turn depth stop 14 in an anticlockwise direction until no more threads can be
  seen.

Clearing Jams (see figures G1–G3)
Single nails can become jammed in the shot duct. If this should occur frequently, please contact an authorized service agent for Bosch power tools.
Note: When the driver blade does not return after clearing a jam, please contact an authorized service agent for Bosch power tools.

• Empty the magazine 11. (See “Emptying the Magazine”, page 24)
• Press clamping lever 3 down so that the shot duct opens.
• Remove the jammed nail. For this, us a pair of pliers, if required.
• When driver blade 19 is extended, push it back into the piston using a lubricated screwdriver or another suitable lubricated object.
• Lubricate the shot duct with 2–3 drops of engine oil (SAE 10 or SAE 20).
• Close the shot duct, hang the clip of clamping lever 3 into the hooks on the shot duct and then push the clamping lever up again.
• Refill the magazine. (See “Loading the Magazine”, page 22)

Changing the Workpiece Protector (see figure H)
The workpiece protector 1 at the end of the discharge lock-off 2 protects the workpiece until the pneumatic tool is correctly placed for the driving procedure.
The workpiece protector can be removed and replaced.

• Pull the workpiece protector from the discharge lock-off.
• Push the new workpiece protector via the open end over the discharge lock-off.

Note: A spare workpiece protector can be stored at the top side of magazine 11. For this, push the workpiece protector into depot 9.

Adjustable Air-outlet cap (see figure I)
With the adjustable exhaust cap at air outlet 4, it is possible to deflect the exhaust air away from yourself or the workpiece.
Transport and Storage
For transport, disconnect the pneumatic tool from the air supply; especially when using ladders or moving in an unusual stance or posture.
At the workplace, carry the pneumatic tool only by the handle 7 and with the trigger 5 released. Always store the pneumatic tool disconnected from the air supply and at a clean and dry location. When not using the pneumatic tool for a longer period of time, cover steel parts with a fine oil coating. This prevents the formation of rust.

Maintenance and Service

Maintenance and Cleaning
Disconnect the air supply before making any adjustments, changing accessories, or placing the pneumatic tool aside. This safety measure prevents accidental starting of the pneumatic tool.
If the pneumatic tool should fail despite the care taken in manufacture and testing, repair should be carried out by an authorized customer services agent for Bosch power tools.
In all correspondence and spare parts orders, please always include the 10-digit article number given on the type plate of the pneumatic tool.
▶ Have maintenance and repair work carried out only through qualified persons. This will ensure that the safety of the pneumatic tool is maintained. An authorized Bosch after-sales service agent will carry out this work quickly and reliably.

Lubricating the Pneumatic Tool (see figure J)
When the pneumatic tool is not connected to a maintenance unit, it must be lubricated at regular intervals:

• For light-duty use 1x per day.
• For heavy-duty use 2x per day.

Apply 2–3 drops of lubricant into air connector 8. Do not apply too much lubricant, which could then accumulate in the pneumatic tool and be emitted via air outlet 4.
Use only the lubricants recommended by Bosch.

• SAE 10 mineral engine oil (for use at very cold ambient conditions)
• SAE 20 mineral engine oil

Observe all applicable environmental regulations when disposing of old grease and solvents.

Maintenance Schedule
Always keep air outlet 4, discharge lock-off 2, and trigger 5 clean and free of foreign material (dust, chips, sand, etc).
Clean the magazine 11. Remove any plastic or wood chips that may accumulate in the magazine during operation. Clean the pneumatic tool in regular intervals using compressed air.
