Screwdriving (Fig. 3)
1. Select the desired speed/torque range using the gear shifter (F) to
match the speed and torque to the planned operation.
2. Turn the torque adjustment collar (E) to the desired position.
NOTE: Use the lowest torque setting required to seat the fastener
at the desired depth. The lower the number, the lower the torque
output.
3. Insert the desired fastener accessory into the chuck as you would
any drill bit.
4. Make some practice runs in scrap or on unseen areas of
the workpiece to determine the proper position of the torque
adjustment collar.
5. Always start with lower torque settings, then advance to higher
torque settings to avoid damage to the workpiece or fastener.
NOTE: When torque is achieved in screwdriving mode, the unit will
automatically shut off with a set of short pulses.
Drilling (Fig. 4)
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 (F) to
match the speed and torque to the planned operation. Turn the
collar (E) 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 drill 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 or
improperly used. RELEASE TRIGGER IMMEDIATELY, remove
drill bit from work, and determine cause of stalling. DO NOT
DEPRESS TRIGGER ON AND OFF 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.
Hammerdrilling (Fig. 5)
1. Select the desired speed/torque range using the gear shifter (F) to
match the speed and torque to the planned operation. Turn the
collar (E) to the hammerdrill symbol.
IMPORTANT: Use carbide-tipped or masonry bits rated for
percussion drilling only.
2. Drill with just enough force on the hammer to keep it from
bouncing excessively or "rising" off the bit. Too much force will
cause slower drilling speeds, overheating, and a lower drilling rate.
3. Drill straight, keeping the bit at a right angle to the work. Do not
exert side pressure on the bit when drillling as this will cause
clogging of the bit flutes and a slower drilling speed.
