ENGLISH

WARNING: To reduce the risk of

serious personal injury, ALWAYS hold

securely in anticipation of a sudden

reaction.

Proper hand position requires one hand on top of

the housing, with the other hand on the grip (h).

SWITCHING ON AND OFF (FIG. 1, 6)

1. To run the tool, press the variable speed switch

(a). The pressure exerted on the variable speed

switch determines the tool speed.

2. To stop the tool, release the switch.

3. To lock the tool in the off position, move the

forward/reverse slider (b) to the central position.

WARNING: To reduce the risk of

personal injury the drill is equipped with

a brake to stop the tool as soon as the

variable speed switch is fully released.

Drill Operation

1. Select the desired speed/torque range using the

gear shifter to match the speed and torque to

the planned operation.

2. For WOOD, use twist bits, spade bits, power

auger bits or hole saws. For METAL, use high-

speed steel twist drill bits or hole saws. Use

a cutting lubricant when drilling metals. The

exceptions are cast iron and brass which should

be drilled dry.

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.

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 CLICK

TRIGGER OFF AND ON IN AN ATTEMPT

TO START A STALLED DRILL – THIS CAN

DAMAGE THE DRILL.

6. Keep the motor running when pulling the bit

back out of a drilled hole. This will help prevent

jamming.

SCREWDRIVING (FIG. 1)

1. Select forward or reverse rotation using the

slider(b). Match the speed and torque to the

planned operation. Insert the desired fastener

accessory into the chuck as you would any drill

bit.

2. Set the collar (d) to position 1 and begin

screwdriving (low torque). Make a few practice

runs in scrap or unseen areas to determine the

proper position of the clutch collar.

3. If the clutch ratchets too soon, adjust the collar

to increase the torque as required.
