HOW TO USE

CAUTION
To prevent accidents, make sure to turn the switch
off and disconnect the plug from the receptacle
when the drill bits and other various parts are
installed or removed. The power switch should
also be turned off during a work break and after
work.
1. Switch operation
○ The rotation speed of the drill bit can be controlled
steplessly by varying the amount that the trigger
switch is pulled. Speed is low when the trigger switch
is pulled slightly and increases as the switch is pulled
more. To turn the switch OFF, release the trigger
switch to its original position. However, the switch
trigger can only be pulled in halfway during reverse and
rotates at half the speed of forward operation.
○ Pulling the trigger and pushing the stopper, it keeps
the switched-on condition which is convenient for
continuous running. When switching off , the stopper
can be disconnected by pulling the trigger again. The
switch stopper is unusable during reverse.
