3. The speed of the cordless drill is controlled 

by the movement of the trigger: the more the 

Trigger Switch is pressed down, the faster the 

cordless drill will run.
4. Release the Trigger Switch to stop the tool.

 If the power tool gets 

excessively hot in use, stop using the tool 

immediately and allow to cool before 

continuing work. The cooling period can be 

reduced by operating the cordless drill at 

maximum speed with no load. Always make sure 

the Motor Vents (H) are not blocked and do not 

allow dust to enter the body of the tool through 

the Motor Vents; dust, especially metallic dust, 

may damage or the tool.

Maintenance

 

Before carrying out any 

maintenance/cleaning of the Battery Charger 

ALWAYS

 disconnect from the power source. 

Remove the battery before carrying out any 

maintenance/cleaning of the cordless drill.

Note:

 The charger contains no user-serviceable 

parts. If the device does not perform as outlined 

in this manual, contact Technical Support.

• Regularly check that all the fixing screws are 

tight.

• Inspect the supply cord of the tool, prior to each 

use, for damage or wear. 

Cleaning

• Keep your tool clean at all times. Dirt and dust 

will cause internal parts to wear quickly, and

shorten the machine’s service life. Clean the 

body of your machine with a soft brush, or dry 

cloth.

If available, use clean, dry, compressed air to 

blow through the ventilation holes.

• Clean the tool casing with a soft damp cloth 

using a mild detergent. Do not use alcohol, 

gasoline or strong cleaning agents.

• Never use caustic agents to clean plastic parts.

Lubrication

• Slightly lubricate the Chuck Locking Collar at 

regular intervals with a suitable spray lubricant.

INSTRUCTIONS

Speed Selection Continued from Page10

Note: ALWAYS

 read the documentation provided 

with drill bits and accessories for the 

recommended or maximum speed setting and use 

the most appropriate gear. See ‘Specification’ for 

the maximum no load speed of each gear.

Torque Selection

This cordless drill is equipped with a torque 

control clutch allowing the machine to be set to 

the correct torque for the individual application.

• The clutch settings are indicated by the numbers 

(1-18) on the Torque Position Selector (C).
• Rotate the Torque Selector to select the desired 

setting: the higher the number displayed on the 

Torque Position Selector, the higher the torque 

produced by the tool.
• For drilling, select the drilling mode on the 

Torque Position Selector.

Direction/Rotation of Bit

 

The rotational direction of the 

bit cannot be changed while the cordless drill is

running. 

DO NOT

 attempt to change the rotational 

direction while the cordless drill is running as this

may cause permanent damage to the tool.
• Use the Forward/Reverse Switch (J) to change 

the direction of the bit rotation.
• For counter-clockwise rotation, push the switch 

to the right.

• For clockwise rotation, push the switch to the left

Note:

 When the Forward/Reverse Switch is in the 

central position, the cordless drill is locked and

cannot be switched ‘ON’. Use this setting as a 

safety feature to prevent the impact driver from 

being switched ‘ON’ accidentally, especially during 

storage and transportation.

Switching ON & OFF

 ALWAYS

 wear adequate 

personal protective equipment when setting up 

and operating this machine.
1. To start the cordless drill, depress the Trigger 

Switch (E).
2. The built-in LED Work Light (D) will illuminate 

when the Trigger Switch is depressed.

Note:

 If the Trigger Switch cannot be pressed 

down, check that the Forward/Reverse Switch (J) 

is not set to its middle position, which locks the 

device (see ‘

Direction/Rotation of Driver Bit

’).
