► Fig.4: 1. Lamp
CAUTION:
Do not look in the light or see the
source of light directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp goes out approximately 10 seconds after
releasing the switch trigger.
NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
Reversing switch action
► Fig.5: 1. Reversing switch lever
CAUTION:
Always check the direction of
rotation before operation.
CAUTION:
Use the reversing switch only after
the tool comes to a complete stop. Changing the
direction of rotation before the tool stops may dam-
age the tool.
CAUTION:
When not operating the tool,
always set the reversing switch lever to the neu-
tral position.
This tool has a reversing switch to change the direction of rota-
tion. Depress the reversing switch lever from the A side for clock-
wise rotation or from the B side for counterclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch trigger cannot be pulled.
Selecting the action mode
NOTICE:
Do not rotate the action mode chang-
ing knob when the tool is running. The tool will be
damaged.
NOTICE:
To avoid rapid wear on the mode
change mechanism, be sure that the action mode
changing knob is always positively located in one
of the three action mode positions.

Torque limiter
NOTICE:
As soon as the torque limiter actuates,
switch off the tool immediately. This will help pre-
vent premature wear of the tool.
NOTICE:
Drill bits such as hole saw, which tend
to pinch or catch easily in the hole, are not appro-
priate for this tool. This is because they will cause
the torque limiter to actuate too frequently.
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output shaft. When this happens, the drill bit will stop
turning.
Electronic function
The tool is equipped with the electronic functions for
easy operation.
• Constant speed control
The speed control function provides the constant
rotation speed regardless of load conditions.
