(optional accessory) must be used for dust
extraction, not the standard dust canister
(Fig. 12). If required, remove the dust cap for
small drill bits.
To insert the dust cap for core bits, push it from
above into the dust extraction system until you
hear it click into place (Fig. 12).
To remove of the dust cap for core bits, push
the release latch outward and pull off the dust
cap.
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 (Fig. 1).
REVERSING SWITCH LEVER
This tool is equipped with a rotating brush
reversing system. This results in longer tool life
while maximizing power in both forward and re-
verse directions. The reverse switch can be
operated from either the right or left side of the
tool.
SLIP CLUTCH
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.
