Children should be supervised at all times if they are in the area in which the tool is being used. It is also imperative that you observe the accident prevention regulations in force in your area. The same applies for general rules of occupational health and safety. The manufacturer shall not be liable for any changes made to the tool nor for any damage resulting from such changes. Even when the tool is used as prescribed it is not possible to eliminate all residual risk factors. The following hazards may arise in connection with the tool’s construction and design: • Damage to the lungs if an effective dust mask is not worn. • Damage to hearing if effective ear defenders are not worn. Wear goggles Wear earmuffs Wear a breathing mask Unpacking Due to modern mass production techniques, it is unlikely that your GMC Power Tool is faulty or that a part is missing. If you find anything wrong, do not operate the tool until the parts have been replaced or the fault has been rectified. Failure to do so could result in serious personal injury.

Turn the auxiliary handle (9) anti-clockwise to loosen the collar and slip it over the chuck onto the drill (Fig. A). 2. Insert the depth gauge (10) in the hole at the top of the handle (9) (Fig. B). A B 3. The auxiliary handle (9) can be swivelled around 360° to find the position that offers most comfort and the easiest operation. 4. The depth gauge (10) helps keep an accurate depth when drilling holes to a set depth. 5. To change the position of the depth gauge (10), turn the grip of the handle (9) anti-clockwise until the depth gauge is loose enough to slide in the hole. 6. Set the depth, checking the depth with a steel rule for most accurate measurement (Fig. C). 7. Then turn the handle grip clockwise to tighten both the depth stop and the auxiliary handle in the required position (Fig. D). C D Installing and removing bits CAUTION. Always ensure that the drill is switched off and plug is removed from the power socket before installing or removing drill bits. The drill features an SDS-Plus® system which enables easy and safe bit replacement. Before inserting an SDS-Plus® bit always ensure that the bit end is clean and greased. 1. Pull back the locking sleeve (11) and insert the bit into the chuck opening taking care that the splines on the shaft of the bit locate properly within the chuck (Fig. E). 2. Test for proper location by releasing the locking sleeve (11) and giving the bit a sharp pull. If the bit can be removed, again pull back the locking sleeve, rotate the bit a fraction of a turn and re-insert it into the chuck (Fig. F). E F 3. Release the locking sleeve and again test for proper location. Repeat if necessary until you are sure that the bit is properly secured. 4. To remove the bit, pull back the locking sleeve (11), remove the bit, and release the locking sleeve (Fig. G). Note. Hammer action drilling is only possible with the drill set for forward rotation. G 8 Operation Starting and stopping 1. Plug the cordset into the mains socket. 2. Depress the on/off trigger switch (1) to start the drill and release the trigger when you wish to stop (Fig. H). Variable speed 1. The speed of the drill can be adjusted using the variable speed dial (8). 2. To increase the speed, turn the dial clockwise (Fig. I). 3. To decrease the speed, turn the dial anti-clockwise (Fig. J). H I J 4. Selecting the speed enables the user to have greater control of the tool and allows drilling in a variety of materials. Note. The speed can be changed while the drill is running. Forward/reverse 1. The forward/reverse lever switch (4) is located immediately above the trigger switch (1). 2. It determines the direction of rotation of the tool and serves as a lock off control. 3. To select forward rotation, release the trigger switch and push the forward/reverse lever switch to the left side of the tool (Fig. K). K 4. To select reverse, push the forward/reverse lever switch (4) to the right side of the tool (Fig. L). 5. When the switch (4) is left in middle position, it locks the motor (Fig. M). L M WARNING. When changing the position of the switch (4) be sure the trigger is released and the motor is stationary. Any attempt to reverse the direction of rotation whilst the drill is turning is likely to permanently damage the switch. Note. The first time ...
