OPERATION
TWO-SPEED GEARBOX SWITCH
(FIG. 8)
Your tool is equipped with two separate
speed ranges: speed 1 (low speed) and
speed 2 (high speed). Speed 1 provides
high-torque and slower drilling speeds
for heavy duty-work or for driving screws.
Speed 2 provides faster speeds for drilling
and lighter work. To change speeds, slide
gearbox switch, to the high or low position.
NOTICE: Do not change speeds when the
tool is running. Always allow the drill to
come to a complete stop before changing
speeds.
NOTICE: Avoid running the hammer drill
at low speed for extended periods of time.
Running at low speed under constant use
may cause the drill to become overheated.
If this occurs, cool the drill by running it
without a load at high speed.

MODE SELECTION (FIG. 9)
Your tool has three operating modes: drilling
with hammering action, drilling only, and
driving screws. -To set the operating mode,
rotate the mode-selector ring and torque-
adjustment ring to the desired settings.
To use the hammer-drilling mode:
1. Rotate the mode-selector ring until the
hammer symbol
appears in line with
the arrow.
2. Apply pressure to the bit during
operation to engage the hammering
mechanism.
NOTE: The number selected on the
torque-adjustment ring has no effect on
operation of the drill in hammer mode.
To use the drilling only mode:
Rotate the mode-selector ring until the drill
symbol appears in line with the arrow.
NOTE: The number selected on the
torque-adjustment ring has no effect on
the operation of the drill in the drilling
mode.
To use the driving screws mode:
1. Rotate the mode selector ring until the
drive symbol appears in line with the
arrow.
2. Then rotate the torque-adjustment ring
until the desired clutch setting appears
in line with the arrow. The torque-
adjustment ring, when properly adjusted,
will slip at a preset torque to prevent
driving the screw too deeply into different
materials and to prevent damage to the
screw or tool.
