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.

The hook is convenient for temporarily hanging the tool.
To use the hook, simply lift up hook until it snaps into
the open position. When not in use, always lower hook
until it snaps into the closed position.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched
off and unplugged before carrying out any work on the tool.
Side grip (auxiliary handle)
CAUTION:
Always use the side grip to ensure
safe operation.
CAUTION:
After installing or adjusting the side
grip, make sure that the side grip is firmly secured.
Install the side grip so that the grooves on the grip fit in
the protrusions on the tool barrel. Turn the grip clock-
wise to secure it. The grip can be fixed at desired angle.
► Fig.13: 1. Side grip
Grease
Coat the shank end of the drill bit beforehand with a
small amount of grease (about 0.5 - 1 g).
This chuck lubrication assures smooth action and longer service life.
Installing or removing drill bit
Clean the shank end of the drill bit and apply grease
before installing the drill bit.
► Fig.14: 1. Shank end 2. Grease
Insert the drill bit into the tool. Turn the drill bit and push
it in until it engages.
After installing the drill bit, always make sure that the
drill bit is securely held in place by trying to pull it out.
► Fig.15: 1. Drill bit
To remove the drill bit, pull the chuck cover down all the
way and pull the drill bit out.
