Drilling (Fig. 3)
NOTICE: If drilling thin material, use a wood "back-up" block to
prevent damage to the material.
1. Select the desired speed/torque range using the gear shifter to
match the speed and torque to the planned operation. Set the
mode control collar to the drill symbol.
2. Use sharp drill bits only. For MASONRY, such as brick, cement,
cinder block, etc., use carbide-tipped bits rated for percussion
drilling.
3. Always apply pressure in a straight line with the bit. Use enough
pressure to keep the drill bit biting, but do not push hard enough
to stall the motor or deflect the bit.
4. Hold tool firmly with both hands to control the twisting action of
the drill. If model is not equipped with side handle, grip drill with one
hand on the handle and one hand on the battery pack.
WARNING: Drill may stall if overloaded causing a sudden twist.
Always expect the stall. Grip the drill firmly to control the twisting
action and avoid injury.
5. IF DRILL STALLS, it is usually because it is being overloaded.
RELEASE TRIGGER IMMEDIATELY, remove drill bit from work,
and determine cause of stalling. DO NOT DEPRESS TRIGGER
OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL
– THIS CAN DAMAGE THE DRILL.
6. To minimize stalling or breaking through the material, reduce
pressure on drill and ease the bit through the last fractional part of
the hole.
7. Keep the motor running when pulling the bit back out of a drilled
hole. This will help prevent jamming.
Screwdriving (Fig. 4)
1. Select the desired speed/torque range using the three-speed gear
shifter (G) on the top of the tool to match the speed and torque to
the planned application. Initially set the torque adjustment collar (E)
at a lower setting to ensure the fastener is set to your specification.
NOTE: Use the lowest torque setting required to seat the fastener
at the desired depth. The lower the number, the lower the torque
output.
2. Rotate the mode control collar (F) so the screw symbol is aligned
with the arrow.
3. Make a few practice runs in scrap or unseen areas of the workpiece
to determine the proper position of the torque adjustment collar.
Reset the torque adjustment collar (E) to the appropriate number
setting for the torque desired.
4. Always start with lower torque settings, then advance to higher
torque settings to avoid damage to the workpiece or fastener.
NOTE: The torque adjustment collar may be set to any number at any
time. However, the torque adjustment collar is only engaged during
screwdriving mode and not in drill and hammerdrill modes.
Hammerdrilling (Fig. 5)
1. Select the desired speed/torque range using the gear shifter to
match the speed and torque to the planned operation. Set the
mode control collar to the hammer symbol.
IMPORTANT: Use carbide-tipped or masonry bits rated for
percussion drilling only.
