Your tool is equipped with a forward/
reversing lever and trigger lock located
above the trigger (Fig. 1). This lever was
designed for changing rotation of the chuck,
and for locking the trigger in an “OFF”
position to help prevent accidental starts
and accidental battery discharge. For
forward rotation, (with chuck pointed away
from you) move the lever to the far left. For
reverse rotation move the lever to the far
right. To activate trigger lock move lever to
the center off position.
Do not change direction of
rotation until the tool comes
to a complete stop. Shifting during rotation
of the chuck can cause damage to the tool.
The tool has an internal preset clutch. The
clutch is set such that sufficient force is
transmitted to the bit for most drilling
conditions but it will slip when bit binds in
the hole or the tool is overloaded. Be aware
that due to required clutch setting, you may
experience a torque reaction an instant
before the clutch slips. This torque reaction
will twist the body of the rotohammer in the
opposite direction as the bit rotates, i.e.,
counterclockwise. As clutch is slipping, the
bit will most likely stop rotating. When the
binding force on the bit is removed the
clutch automatically resets. If you
experience bit binding and clutch begins to
slip, immediately turn the tool "OFF" and
correct the condition leading to the bit
binding.
Your tool is equipped with a variable speed
trigger switch. The tool speed can be
controlled from the minimum to the
maximum nameplate RPM by the pressure
you apply to the trigger. Apply more
pressure to increase the speed and release
pressure to decrease speed. This accurate
speed control enables you to drill without
center punching. It also permits you to use
as a power screwdriver. Bits are available for
driving screws as well as running bolts and
nuts.

AUXILIARY HANDLE
The tool should be supported with the
auxiliary handle, which can be swiveled 360˚.
To swivel the handle loosen the hand grip,
move the handle to desired position, and
securely retighten the hand grip.
DEPTH GAUGE
Your drilling depth can be pre-set and/or
repeated by using the depth gauge.
Setting depth: After the auxiliary handle is
installed, make sure the accessory has been
fully inserted into the tool holder before
setting the depth gauge.
To adjust depth, push the depth gauge
release button, slide the depth gauge to
desired depth and release pressure on
button to lock the depth gauge in place.
BRAKE
When the trigger is released it activates the
electrical brake to stop the chuck quickly.
This is especially useful in the repetitive
driving and removal of screws.
