10. Switch operation
⅜

rotates. When the trigger is released, the tool stops.

The rotational speed of the drill can be controlled
by varying the amount that the trigger switch is
pulled. Speed is low when the trigger switch is
pulled slightly and increases as the trigger switch
is pulled more.
NOTE:
A buzzing noise is produced when the motor is
about to rotate. This is only a noise, not a machine
failure.
11. For drilling into brick
Excessive pressing force never increases drilling
speed. It will not only damage the drill tip or reduce
working efficiency, but could also shorten the
service life of drill bit. Operate the hammer drill
within 10-15 kg pressing force while drilling into
brick.
12. Using the hook
The hook is used to hang up the power tool to your
waist belt while working.
CAUTION
●
When using the hook, hang up the power tool
firmly not to drop accidentally.
If the power tool is dropped, it may lead to an
accident.

●
When carrying the power tool with hooked to your
waist belt, do not fit any bit to the tip of power
tool. If the sharp bit such as drill is fitted to the
power tool when carrying it with hooked to your
waist belt, you will be injured.
●
Install securely the hook. Unless the hook is securely
installed, it may cause an injury while using.
(1) Removing the hook.
Remove the screws fixing the hook with Philips
screw driver. (Fig. 11)
(2) Replacing the hook and tightening the screws.
Install securely the hook in the groove of power
tool and tighten the screws to fix the hook firmly.
