Hints for use

Note.

 When drilling into masonry, the drilling rate is fast and 

burnout of the tip will occur if the drill bit is not constantly 

cleared.
•  Use only correctly sharpened drill bits, which are suitable 

for the material being drilled.

•  To drill hard materials, apply enough firm pressure only to 

safely control the powertool. Excessive pressure does not 

improve performance and places unnecessary pressure 

on the tool and its bit.

•  When driving screws, always use a pilot hole and set the 

speed dial to low.  

•  It is always wiser to test the screw driving on a scrap 

piece of the same material you are using.

•  Larger diameter holes in hard wood, steel and concrete 

have to be drilled at slower speeds. However, the motor 

must not be struggling with the operation. If the motor is 

struggling DO NOT continue working, pull the drill clear of 

the workpiece and run it on fast speed for a minute or so 

allowing the motor time to cool down before you attempt 

a little more of the work. 

•  If the job is too hard for the drill, do not continue, 

otherwise permanent damage to the motor will occur.

•  Concrete drilling should be carried out on the highest 

speed.

DO NOT

 overload motor when drilling concrete.

DO NOT

 use too much pressure as the hammer action 

relies on the drill bit being able to move back and forward in 

the hole being drilled. Always clear the flutes of the drill bit 

by removing it from the hole regularly.

WARNING.

 This tool is not designed for high torque 

applications such as screwdriving. Such use will damage 

the motor.

Gearbox maintenance

1. Carry out the following procedure after each period of 

approximately 6 hours of use.

2. Remove the gear case access 

cover (3) located on top of the 

drill.

3. Use wrench (13) to unscrew 

the gearbox cover.

4. Use a spatula or similar 

instrument to apply general 

machinery grease into the 

gearbox cavity until it is full. 

5. Be careful not to scratch or otherwise damage the 

mechanism.

6. Replace the cover (3).

CAUTION.

 Do not over-tighten cover (3) or overfill the 

gearbox with grease. If you run out of grease, or are not 

sure how to change the grease, please take your product to 

the nearest authorised service centre and have a qualified 

person replace the grease.

Maintenance

WARNING.

 Always ensure that the tool is switched off and 

the plug is removed from the power point before making any 

adjustments or maintenance procedures.
1. Keep the tool’s air vents unclogged and clean at all times.
2. Regularly check to see if any dust or foreign matter has 

entered the grills near the motor and around the trigger 

switch. Use a soft brush to remove any accumulated 

dust. Wear safety glasses to protect your eyes whilst 

cleaning.

3. If the body of the drill needs cleaning, wipe it with a soft 

damp cloth. A mild detergent can be used but nothing like 

alcohol, petrol or other cleaning agent.

4. Never use caustic agents to clean plastic parts.

CAUTION.

 Water must never come into contact with the 

tool.
