FUNCTIONAL
DESCRIPTION
CAUTION:
Always be sure that the tool is
switched off and unplugged before adjusting or
checking function on the tool.
Switch action
CAUTION:
Before plugging in the tool, always
check to see that the switch trigger actuates
properly and returns to the “OFF” position when
released.
CAUTION:
Switch can be locked in “ON” posi -
tion for ease of operator comfort during extended
use. Apply caution when locking tool in “ON”
position and maintain firm grasp on tool.
► Fig.1: 1. Switch trigger 2. Lock button
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.
For continuous operation, pull the switch trigger, push
in the lock button and then release the switch trigger.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
Reversing switch action
CAUTION:
Always check the direction of
rotation before operation.
NOTICE:
Use the reversing switch only after the
tool comes to a complete stop. Changing the direc-
tion of rotation before the tool stops may damage the
tool.
NOTICE:
If the switch trigger can not be
depressed, check to see that the reversing switch
is fully set to position (A side) or (B side).
► Fig.2: 1. Reversing switch lever
This tool has a reversing switch to change the direc-
tion of rotation. Move the reversing switch lever to the
position (A side) for clockwise rotation or to the posi-
tion (B side) for counterclockwise rotation.
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.
Rotation with hammering
For drilling in concrete, masonry, etc., rotate the action
mode changing knob to the
symbol. Use a tungsten-
carbide tipped bit (optional accessory).
► Fig.3: 1. Action mode changing knob
Rotation only
For drilling in wood, metal or plastic materials, rotate
the action mode changing knob to the symbol. Use a
twist drill bit or wood drill bit.
► Fig.4: 1. Action mode changing knob
Hammering only
For chipping, scaling or demolition operations, rotate
the action mode changing knob to the symbol. Use a
bull point, cold chisel, scaling chisel, etc.
► Fig.5: 1. Action mode changing knob
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.
