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.

 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 drilling as this will cause 
clogging of the bit flutes and a slower drilling speed.

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.
