FUNCTIONAL DESCRIPTION

CAUTION:

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

Installing or removing the battery cartridge (Fig. 1)

• Always switch off the tool before installing or removing the battery cartridge.
• 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. Always 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. Install it 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 use force when installing the battery cartridge. If the cartridge does not slide in easily, it is not being inserted correctly.

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

Overload protection
This protection works when the tool/battery is operated in a manner that causes it to draw an abnormally high current. In this situation, turn the tool off and stop the application that caused the tool to become overloaded.
Then turn the tool on to restart.

Overheat protection
This protection works when the tool or battery is overheated. In this situation, let the tool and battery cool before turning the tool on again.

Over-discharge protection
This protection works when the remaining battery capacity gets low. In this situation, remove the battery from the tool and charge the battery.

Indicating the remaining battery capacity
Only for battery cartridges with the indicator (Fig. 2)
Press the check button on the battery cartridge to indicate the remaining battery capacity. The indicator lamps light up for a few seconds.

NOTE:

• Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.
• The first (far left) indicator lamp will blink when the battery protection system works.

Setting for desired screw length (Fig. 3)
There are 7 positive-lock screw length settings. To obtain the desired setting, pull out the stopper base while depressing the lever until you see the number of the desired screw length (indicated on the label on the feeder box) appear to rest in the fenestella of the stopper base. See the table below for the relation between the number indicated on the label on the feeder box and the respective screw length.

Adjusting the driving depth (Fig. 4)
Depress the stopper base as far as it will go. While keeping it in this position, turn the adjusting knob until the bit tip projects approx. 5 mm from the stopper base. Drive a trial screw. If the screw head projects above the surface of the workpiece, turn the adjusting knob in the “A” direction; if the screw head is counter-sunk, turn the adjusting the knob in the “B” direction.

Switch action (Fig. 5)
CAUTION:

• Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.

To start the tool, simply pull the switch trigger. Release the switch trigger to stop.

Reversing switch action (Fig. 6)
This tool has a reversing switch to change the direction of rotation. Depress the reversing switch lever from the A-side for clockwise rotation or from the B-side for counterclockwise rotation.
When the reversing switch lever is in the neutral position, the switch trigger cannot be pulled.

CAUTION:

• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool.
• When not operating the tool, always set the reversing switch lever to the neutral position.

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.

WARNING:

• Never use the hanging hole for unintended purposes, for instance, tethering the tool at a high location. Bearing stress is a heavily loaded hole that may cause damage to the hole, resulting in injuries to you or people around or below you. (Fig. 15)

Use the hanging hole at the bottom rear of the tool to hang the tool on a wall using a hanging cord or similar strings.

OPERATION

Driving operation (Fig. 16)
Switch on the tool by pulling the switch trigger. Hold the tool squarely and firmly up against the driving surface. A screw will be automatically carried to the driving position and fastened.
CAUTION:

• Always check the bit carefully for wear before driving operations. Replace a worn bit or poor fastening may result.
• Always hold the tool squarely against the driving surface. Holding it at an angle may damage the screw heads and cause wear on the bit. This may also lead to poor fastening.
• Always keep the tool firmly against the driving surface until the driving is over. Failure to do so may cause insufficient fastening of screws.
• Be careful not to drive a screw onto another screw already fastened.
• Do not operate the tool without screws. It will damage the driving surface.
• Do not apply oil or grease on the sliding surface of the feeder box.

Driving in the corner (Fig. 17)
This tool can be used to drive at a position 15 mm away from the wall as shown in the figure.

CAUTION:

• Driving at a position closer than 15 mm to the wall or driving with the stopper base in contact with the wall may damage the screw heads and cause wear on the bit. This may also lead to the poor fastening of screws and malfunction of the tool.
