Depth gauge
1
011091
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the side grip and insert the depth
gauge into the hole in the grip base. Adjust the depth
gauge to the desired depth and tighten the side grip.
NOTE:
The depth gauge cannot be used at the position where
the depth gauge strikes against the gear housing.

FUNCTIONAL DESCRIPTION

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.

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.

1. Reversing
switch lever
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the
position (A side) for clockwise rotation or to the
position (B side) for counterclockwise rotation.
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.
Selecting the action mode
1
011094
This tool has an action mode change lever. For rotation
with hammering, slide the action mode change lever to
the right ( symbol). For rotation only, slide the action
mode change lever to the left (
CAUTION:
Always slide the action mode change lever all the
•
way to your desired mode position. If you operate
the tool with the lever positioned halfway between
the mode symbols, the tool may be damaged.
OPERATION
Hammer drilling operation
CAUTION:
There is tremendous and sudden twisting force
•
exerted on the tool/bit at the time of hole
break-through, when the hole becomes clogged
with chips and particles, or when striking reinforcing
rods embedded in the concrete. Always use the
side grip (auxiliary handle) and firmly hold the tool
by both side grip and switch handle during
operations. Failure to do so may result in the loss of
control of the toll and potentially serve injury.
When drilling in concrete, granite, tile, etc., slide the
action mode change lever to the position of
to use "rotation with hammering" action. Be sure to use a
tungsten-carbide tipped bit. Do not apply more pressure
when the hole becomes clogged with chips or particles.
Instead, run the tool at an idle, then remove the bit
partially from the hole. By repeating this several times,
the hole will be cleaned out.
