Variable speed is particularly useful when
starting the hammer drill. Also allows you to
set an optimal speed for any kind of job.
FORWARD/REVERSE SWITCH.
The forward/reverse switch determines the
running direction of the tool.
1. To select "forward" motion, release the
trigger switch, and push the forward/reverse
switch to the right side of the tool.
2. To select "reverse" motion, release the
trigger switch, and push the forward/reverse
switch to the left side of the tool.
WARNING: When switching speeds, make
sure to release the trigger and wait for the
hammer drill to stop.
NOTE: When you operate the tool in counter-
clockwise rotation, the switch trigger is pulled
only halfway and the tool runs at half speed.
For counterclockwise rotation, you cannot
push in the lock button.
MECHANICAL SPEED ADJUSTMENT KNOB
The mechanical speed adjustment knob allows
the user select to select an optimal speed.
• Use a Low speed for starting holes without
a center guide, to drill on metal, plastics, ce-
ramics or any other application that require a
higuer torque.
• A Higher speed is used for drilling on wood,
compound wood and for using polish or ab-
brassive accesories.
To set a lower speed with high torque, turn off
the power tool and allow the motor to com-
pletely stops and turn the knob to position 1.
To set a higuer speed
with low torque, turn
off the hammer drill
and allow the motor
to completely stops
and turn the adjust
ment knob to position 2.
NOTE: Make sure that the speed adjustment
knob is well positioned on 1 or 2. Do not
change speed while the power tool is still ON.
If you find difficulties when changing the gear
range, manually turn the chuck until gears are
well positioned.

NOTE:
• Use sharp drill bits only.
• For wood, use twist-drill bits, spade bits,
power-auger bits, or hole saws.
• For metal, use high-speed, steel-twist drill
bits or hole saws.
• For masonry (brick, cement, cinder block,
etc.) use carbide-tipped drill bits.
• Be sure that the material to be drilled is an-
chored or clamped firmly.
• If drilling thin material, use a "back-up" block
in order to prevent damage to the material.
