Operating Instructions
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 speed 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.
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
re verse directions. The reverse switch can be
oper ated from either the right or left side of the
tool.
FOR FORWARD ROTATION: slide switch to
arrow marked forward (Fig. 6).
FOR REVERSE RO TATION: slide the slide
switch to arrow marked re verse (Fig. 7). NOTE:
Tool will not operate in middle position.
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.

KICKBACK CONTROL
The rapid shut-off feature enables better
control and improves user’s comfort. The
power tool automatically shuts off in case of
sudden and unexpected rotation of the power
tool around the drilling axis (for example
jamming of the drill bit in reinforcing steel or
wedging application tool).To restart the
machine, release the On/Off switch and then
actuate again.
Kickack Control can activate only when the
power tool is running at maximum operating
speed and can rotate freely around the drill bit
axis.
