Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. c.
c. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally. d.

• Support the work properly. • If you are interrupted when operating the drill, complete the process and switch off before looking up. • Periodically check that all nuts, bolts and other fixings are properly tightened. • When using the drill, use safety equipment including safety glasses or shield, ear defenders, and protective clothing including safety gloves. Wear a dust mask if the drilling operation creates dust.
• Do not disassemble the charger. Take it to an authorised service centre when service or repair is required. Incorrect re-assembly may result in the risk of fire, electric shock or electrocution. • To reduce the risk of an electric shock, unplug the charger from the power supply before attempting to clean it. Removing the battery alone does not reduce the risk. • Never attempt to connect two chargers together.

Adjustable side handle Fitting and removing the battery pack The drill is supplied with a 360º adjustable side handle (5). Always fit and use the side handle when using the drill, this increases safety when operating the drill. To adjust the side handle, rotate the side handle in an anti clockwise direction approximately 2 full turns. Once the side handle is loose rotate the collar left or right to the desired position. You do not need to fully remove the handle.
To remove the battery pack from the charger depress the battery pack release buttons (6). Depending on room temperature, line voltage, and existing charge level, initial battery charging may take longer than one hour. Disconnect charger from power source when not in use. Battery charging b a c To obtain the best life for the battery Never allow the drill to come to a complete stand still before recharging.
The reverse mode is intended for the removal of screws. The centre position of the control button locks the tool in the off position. 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). Variable speed The variable speed feature is particularly useful when driving screws.
Torque adjustment/hammer selection collar Screw driver bit storage By rotating the torque adjustment/hammer selection collar (2) behind the chuck, it is possible to adjust the torque to each of twenty settings, or select hammer action or the drill setting. The range of twenty torque settings allows better control when using the drill as a screwdriver as it prevents overtightening of the screws. The numbers circling the collar are used to indicate the level of torque.
Drilling metals Drilling wood • For maximum performance, use high speed steel bits for metal or steel drilling. • Ensure that the torque adjustment / hammer selection collar (2) is in normal drilling mode. • Begin drilling at a very low speed to prevent the bit from slipping off the starting point. • Always clamp sheet metal. • Support thin metal with a block of wood to avoid distorting it. • Use a punch to mark the centre of the hole. • Use a suitable lubricant for the material you are working on.
Care • Don’t force the drill, let it work at its own pace • Keep the drill bit sharp. • Reduce pressure, as the drill is about to break through the item being drilled. Maintenance • Store the tools, instruction manual and where necessary the accessories in the original packaging. In this way you will always have all the information and parts ready to hand. • Do not throw used batteries into fire or water.
