Operating Instructions

Trigger switch & reversing button (fig. B, C)

● The drill is turned ON and OFF by pulling and releasing

the trigger switch (1).

The farther the trigger is depressed, the higher the speed

of the drill operates at.

● A forward/reverse control button (2) determines the direc-

tion of the tool and also serves as a lock off button.

● To select forward rotation, release the trigger switch and

depress the forward/reverse control button to the left.

● To select reverse, depress the forward/ reverse control

button the opposite direction.

● To lock the tool, set the forward/reverse slider into the

centre position.

Note: The center position of the control button locks the tool

in the off position. When changing the position of the control

button, be sure the trigger is released.

Torque control (fig. D)

This tool is fitted with a torque adjustment collar (3) to select

the operating mode and to set the torque for tightening

screws. Large screws and hard workpiece materials require

a higher torque setting than small screws and soft workpiece

materials.

● For drilling, set the collar to the drilling position symbol

● For screwdriving, set the collar to the desired setting. If

you do not yet know the appropriate setting, proceed as

follows:

● Set the collar to the lowest torque setting.

● Tighten the first screw.

● If the clutch ratchets before the desired result is achieved,

increase the collar setting and continue tightening the

screw. Repeat until you reach the correct setting. Use this

setting for the remaining screws.

Keyless chuck (fig. E)

Warning! Make certain the lock-off button is engaged

to prevent switch actuation before installing or removing

accessories.

To insert a drill bit or other accessory:

(Original instructions)

● Grasp the rear half of the chuck (6) with one hand and

use your other hand to rotate the front half (7) in the

counterclockwise direction, as viewed from the chuck end.

● Insert the bit or other accessory fully into the chuck, and

tighten securely by holding the rear half of the chuck and

rotating the front portion in the clockwise direction as

viewed from the chuck end.

Warning! Do not attempt to tighten drill bits (or any other

accessory) by gripping the front part of the chuck and turning

the tool on. Damage to the chuck and personal injury may

occur when changing accessories.

Drilling/screwdriving

● Select forward or reverse rotation using the forward/

reverse slider (2).

● To switch the tool on, press the switch (1).

● The tool speed depends on how far you press the switch.

● To switch the tool off, release the switch.

Hints for optimum use

Drilling

● Always apply a light pressure in a straight line with the

drill bit.

● Just before the drill tip breaks through the other side of the

workpiece, decrease pressure on the tool.

● Use a block of wood to back up workpieces that may

splinter.

● Use spade bits when drilling large diameter holes in wood.

● Use HSS drill bits when drilling in metal.

● Use masonry bits when drilling in soft masonry.

● Use a lubricant when drilling metals other than cast iron

and brass.

● Make an indentation using a centre punch at the centre of

the hole to be drilled in order to improve accuracy.

Screwdriving

● Always use the correct type and size of screwdriver bit.

● If screws are difficult to tighten, try applying a small

amount of washing liquid or soap as a lubricant.

● Always hold the tool and screwdriver bit in a straight line

with the screw.
