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.

VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
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.
REVERSING SWITCH LEVER
This tool is equipped with a rotating brush
reversing system. This results in longer brush
life while maximizing power in both forward and
reverse directions. The reverse switch can be
operated from either the right or left side of the
tool (Fig. 1).
FOR FORWARD ROTATION: slide switch to
arrow marked forward.
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(Fig. 5).

Operating Instructions
FOR REVERSE ROTATION: slide the slide
switch to arrow marked reverse. NOTE: Tool
will not operate in middle position.
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 rotary hammer 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.
