LED Work area light  

The drill has five LED lights (14) to illuminate the work  

area and improve vision when drilling in areas with 

insufficient light. 
To turn the LED lights on depress the LED light switch (13). 

To turn the LED lights off repress the LED light switch (13). 

Trigger Switch

To start the drill, depress  

the trigger switch.

Use the forward/reverse  

control (4) to select the 

direction of rotation, then 

squeeze the trigger switch 

(3). This trigger switch 

is an electronic variable 

speed control which enables the user to vary the speed 

continuously. The speed varies according to how far the 

trigger switch is depressed, the further it is depressed the 

faster the chuck will rotate and the lighter it is depressed, 

the slower it will rotate. The switch is equipped with a  

brake, the chuck will stop as soon as the trigger switch is 

fully released. 

To stop the drill, release the trigger switch. 

Forward/Reverse control  

The forward/reverse control 

(4) allows you to change the 

direction of the tool while the 

variable speed trigger is not 

depressed.
To select forward rotation 

depress the control (4) toward 

the left side of the tool. To 

select reverse depress the 

control (4) to the right side of 

the tool. 
Drilling uses the forward mode.

The reverse mode is intended for the removal of screws.
The centre position of the control button locks the tool in the 

off position. 

Variable speed

The variable speed feature is particularly useful when 

driving screws.
It also enables you to select the best speed for a particular 

application. The farther you squeeze the trigger, the faster 

the tool will operate.
Use lower speeds for starting holes without a centre 

punch, drilling metals or plastic, driving screws and drilling 

ceramics, or in any application requiring high torque. Higher 

speeds are better drilling in wood, wood compositions and 

for using abrasive and polishing accessories. For maximum 

tool life, use variable speed only for starting holes or 

fasteners.

Note.

 It is best to use the variable speed feature for a short 

time only. Do not continuously operate the drill in variable 

speed mode this may damage the switch. 

Drilling Positions

This symbol indicates the DRILL POSITION. Use this 

mode for high speed drilling (Wood, Aluminium, and 

Steel) and the clutch will be locked.
This symbol indicates the HAMMER POSITION. Use 

this mode to select hammer action. For best results 

in hammer mode, use set the gear selector (9) to 

Position 3 (high speed).
