to start the drill and release the

trigger when you wish to stop.

Variable speed trigger switch

You can adjust the speed of the drill between zero and

maximum by varying the pressure on the trigger. The harder

you press on the trigger the faster the drill

will operate.

Speed adjustment

You can change the maximum

speed setting by turning the speed

dial (8) located on the trigger switch

the dial so that the thickest part of

the line is above the arrow on the

Reversing the direction

of rotation

1. The forward/reverse switch (6)

protrudes from one side of the

drill to the other.

2. The arrow head symbol on each

side of the switch indicates the

direction of drilling when the

switch is pushed from that side.

The forward direction is selected

when the arrow head symbol

points to the front of the drill. The

reverse direction is selected when

the arrow head symbol points to

the rear of the drill.

CAUTION.

Any attempt to reverse

the direction of rotation whilst the drill is turning

is likely to permanently damage the motor, gearing

or both.

Drilling/hammer mode selector

You can use the drill for both

hammer action and normal drilling.

1. Use the drilling/hammer mode

selector (4) to select hammer or

drill action. The type of drilling

selected is indicated

by the symbol on each side of

the drill.

2. Push the selector to

hammer action.

3. Push the selector to

action.

CAUTION.

Change the mode of

action only when the drill has come

to a complete standstill.
