General Power Tool Safety

Warnings
WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.

CORDLESS JIG SAW SAFETY WARNINGS 

1.  Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
2.  Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
3.  Always use safety glasses or goggles. Ordinary eye or sun glasses are NOT safety glasses.
4.  Avoid cutting nails. Inspect workpiece for any nails and remove them before operation.
5.  Do not cut the oversize workpieces.
6.  Check for the proper clearance beyond the workpiece before cutting so that the blade will not strike the floor, workbench, etc.
7. Hold the tool firmly.
8.  Make sure the blade is not contacting the workpiece before the switch is turned on.
9.  Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool only when hand-held.
11. Always switch off and wait for the blade to come to a complete stop before removing the blade from the workpiece.
12.  Do not touch the blade or the workpiece immediately after operation; they may be extremely hot and could burn your skin.
13. Do not operate the tool at no-load unnecessarily.
14.  Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
15. Always use the correct dust mask/respirator for the material and application you are working with.
    SAVE THESE INSTRUCTIONS.

WARNING:

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product. MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:

Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool.

Installing or removing battery cartridge Fig.1  

CAUTION:

• Always switch off the tool before installing or removing of the battery cartridge.
• Hold the tool and the battery cartridge firmly when installing or removing battery cartridge. Failure to hold the tool and the battery cartridge firmly may cause them to slip off your hands and result in damage to the tool and battery cartridge and a personal injury.
• To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge.
• To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely.
• Always install the battery cartridge fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.
• Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it is not being inserted correctly.

Battery protection system
The tool is equipped with a battery protection system. This system automatically cuts off power to the motor to extend battery life.
The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

Overloaded:
The tool is operated in a manner that causes it to draw an abnormally high current.
In this situation, release the switch trigger on the tool and stop the application that caused the tool to become overloaded. Then pull the switch trigger again to restart.
If the tool does not start, the battery is overheated. In this situation, let the battery cool before pulling the switch trigger again.

Low battery voltage:
The remaining battery capacity is too low and the tool will not operate. If you pull the switch trigger, the motor runs again but stops soon. In this situation, remove and recharge the battery.

Selecting the cutting action
Fig.2
This tool can be operated with an orbital or a straight line (up and down) cutting action. The orbital cutting action thrusts the blade forward on the cutting stroke and greatly increases cutting speed.
To change the cutting action, just turn the cutting action changing lever to the desired cutting action position. Refer to the table to select the appropriate cutting action.

Switch action

CAUTION: 

•  Before installing the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.
• When not operating the tool, depress the lock-off button from A side to lock the switch trigger in the OFF position.

To prevent the switch trigger from accidentally pulled, the lock-off button is provided.
To start the tool, depress the lock-off button from B side and pull the switch trigger.
Tool speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop. After use, always press in the lock-off button from A side.

ASSEMBLY

CAUTION: 

Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

Installing or removing saw blade Fig.3

CAUTION:

• Always clean out all chips or foreign matter adhering to the blade and/or blade holder. Failure to do so may cause insufficient tightening of the blade, resulting in a serious personal injury.
• Do not touch the blade or the workpiece immediately after operation; they may be extremely hot and could burn your skin.
• Always secure the blade firmly. Insufficient tightening of the blade may cause blade breakage or serious personal injury.
• Use only B type blades. Using blades other than B type blades causes insufficient tightening of the blade, resulting in a serious personal injury.

Fig.4
To install the blade, loosen the bolt counterclockwise on the blade holder with the hex wrench.
With the blade teeth facing forward, insert the blade into the blade holder as far as it will go. Make sure that the back edge of the blade fits into the roller. Then tighten the bolt clockwise to secure the blade.
To remove the blade, follow the installation procedure in reverse.

NOTE: Occasionally lubricate the roller.

Hex wrench storage
Fig.5
When not in use, store the hex wrench as shown in the figure to keep it from being lost.
First, insert the hex wrench into the hole. Then push it into the hook until it locked.

Dust cover  

CAUTION:

• Always wear safety goggles even when operating the tool with the dust cover lowered.
• Lower the dust cover to prevent chips from flying. However, when making bevel cuts, raise it all the way.

OPERATION

CAUTION:

• Always hold the base flush with the workpiece. Failure to do so may cause blade breakage, resulting in a serious injury.
• Advance the tool very slowly when cutting curves or scrolling. Forcing the tool may cause a slanted cutting surface and blade breakage.

Fig.7
Turn the tool on without the blade making any contact and wait until the blade attains full speed. Then rest the base flat on the workpiece and gently move the tool forward along the previously marked cutting line.

Bevel cutting
Fig.8

CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before tilting the base.
• Raise the dust cover all the way before making bevel cuts.

Fig.9
With the base tilted, you can make bevel cuts at any angle between 0° and 45° (left or right).
Loosen the bolt on the back of the base with the hex wrench. Move the base so that the bolt is positioned in the center of the cross-shaped slot in the base.
Fig.10
Tilt the base until the desired bevel angle is obtained. The edge of the motor housing indicates the bevel angle by graduations. Then tighten the bolt to secure the base.

Front flush cuts
Fig.11
Loosen the bolt on the back of the base with the hex wrench and slide the base all the way back. Then tighten the bolt to secure the base.
Cutouts
Cutouts can be made with either of two methods A or B.

1. Boring a starting hole
   Fig.12
   For internal cutouts without a lead-in cut from an edge, pre-drill a starting hole 12 mm or more in diameter. Insert the blade into this hole to start your cut.
2. Plunge cutting
   You need not bore a starting hole or make a lead-in cut if you carefully do as follows.
   1. Tilt the tool up on the front edge of the base with the blade point positioned just above the workpiece surface.
   2.  Apply pressure to the tool so that the front edge of the base will not move when you switch on the tool and gently lower the back end of the tool slowly.
   3.  As the blade pierces the workpiece, slowly lower the base of the tool down onto the workpiece surface.
   4.  Complete the cut in the normal manner.

Finishing edges Fig.14
To trim edges or make dimensional adjustments, run the blade lightly along the cut edges.

Metal cutting
Always use a suitable coolant (cutting oil) when cutting metal. Failure to do so will cause significant blade wear. The underside of the workpiece can be greased instead of using a coolant.
Dust extraction
Fig.15
Clean cutting operations can be performed by connecting this tool to a Makita vacuum cleaner. Insert the hose of the vacuum cleaner into the hole at the rear of the tool. Lower the dust cover before operation.
NOTE:
Dust extraction cannot be performed when making bevel cuts.

Rip fence (optional accessory)

CAUTION:
Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing accessories.

1. Straight cuts
   When repeatedly cutting widths of 160 mm or less, use of the rip fence will assure fast, clean, straight cuts.
   To install, insert the rip fence into the rectangular hole on the side of the base with the fence guide facing down. Slide the rip fence to the desired cutting width position, then tighten the bolt to secure it.
2. Circular cuts
   When cutting circles or arcs of 170 mm or less in radius, install the rip fence as follows.
   Insert the rip fence into the rectangular hole on the side of the base with the fence guide facing up. Insert the circular guide pin through either of the two holes on the fence guide. Screw the threaded knob onto the pin to secure the pin.
   Now slide the rip fence to the desired cutting radius, and tighten the bolt to secure it in place. Then move the base all the way forward.

NOTE:  

Always use blades No. B-17, B-18, B-26 or B-27 when cutting circles or arcs.

Anti-splintering device (optional accessory)
Fig.20
For splinter-free cuts, the anti-splintering device can be used. To install the anti-splintering device, move the tool base all the way forward and fit it from the back of tool base. When you use the cover plate, install the anti-splintering device onto the cover plate.

CAUTION:
The anti-splintering device cannot be used when making bevel cuts.

Cover plate (Optional accessory)
Fig.21
Use the cover plate when cutting decorative veneers, plastics, etc. It protects sensitive or delicate surfaces from damage. Fit it on the back of the tool base.
