Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the battery
cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room
temperature at 10°C - 40°C (50°F - 104°F). Let a hot
battery cartridge cool down before charging it.

ENC009-1
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
The battery cartridge 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 remove causes of overload and
then pull the switch trigger again to restart.
• When battery cells get hot:
If any operation of the switch trigger, the motor will
remain stopped. At this time, stop use of the tool and
cool the battery cartridge.
• When the remaining battery capacity gets low:
If you pull the switch trigger, the motor runs again but
stops soon. In this case, to prevent over discharge,
remove the battery cartridge from the tool and charge
it.
Switch action (Fig. 2)
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. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
Reversing switch action (Fig. 3)
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.
Speed change (Fig. 4)
To change the speed, first switch off the tool and then
slide the speed change lever to the "2" side for high speed
