- Do not use a damaged battery.
SAVE THESE INSTRUCTIONS.
Tips for maintaining maximum battery life
- Charge the battery cartridge before completely discharged. Always stop tool operation and charge the battery cartridge when you notice less tool power.
- Never recharge a fully charged battery cartridge. Overcharging shortens the battery service life.
- Charge the battery cartridge with room temperature at 10 ゚ C – 40 ゚ C (50 ゚ F – 104 ゚ F). Let a hot battery cartridge cool down before charging it.
- Charge the battery cartridge once in every six months if you do not use it for a long period of time.
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
- Always switch off the tool before installing or removing of 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.
Battery protection system (Battery cartridge with a star mark)
Fig.2
The battery cartridge with a star mark is equipped with the protection system,
which automatically cuts off the output power for its long service life. The
tool stops during operation when the tool and/or battery are placed under the
following situation. This is caused by the activation of protection system and
does not show the tool trouble.
- When the tool is overloaded: At this time, release the switch trigger,remove the battery cartridge and removecauses of overload and then pull the switchtrigger again to restart.
- When battery cells get hot: If any operation of the switch trigger, themotor will remain stopped. At this time, stopuse of the tool and cool or charge the batterycartridge after removing it from the tool.
- When the remaining battery capacity gets low: If any operation of the switch trigger, themotor will remain stopped. At this time, remove the battery cartridge from the tool and charge it .

• 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.
Depth adjustment
Fig.6
The depth can be adjusted by turning the locator. Turn it in “B” direction for
less depth and in “A” direction for more depth. One full turn of the locator
equals 2 mm change in depth.
Fig.7
Adjust the locator so that the distance between the tip of the locator and the
screw head is approximately 3 mm as shown in the figures. Drive a trial screw
into your material or a piece of duplicate material. If the depth is still not
suitable for the screw, continue adjusting until you obtain the proper depth
setting.
