TRIGGER SWITCH & REVERSING BUTTON - FIGURE 4
The drill is turned ON and OFF by pulling and releasing the trigger switch (A) shown in
figure 4. The farther the trigger is depressed, the higher the speed of the drill. A
forward/reverse control button (B) determines the direction of the tool and also serves
as a lock off button. To select forward rotation, release the trigger switch and depress
the forward/reverse control button to the left. To select reverse, depress the forward/reverse
control button to the right. The center position of the control button locks the tool in the off
position. When changing the position of the control button, be sure the trigger is released.
TORQUE CONTROL - FIGURE 5
To set the tool’s torque, rotate the adjustable torque collar as required. There are 24
clutch settings in all. These are indicated by numbers depicted on the torque collar. For
light duty work when using small screws, set the collar to the smallest number.
Large screws and hard workpiece materials require a higher torque setting than small
screws and soft workpiece materials.
For drilling in wood, metal and plastics, set the adjustable torque collar to the drilling
position symbol .
For screwdriving, set the adjustable torque collar to the desired setting. If you do not
yet know the appropriate setting, proceed as follows:
Set the collar to the lowest torque setting.
Tighten the first screw.
If the clutch ratchets before the desired result is achieved, increase the collar setting
and continue tightening the screw. Repeat until you reach the correct setting. Use
this setting for the remaining screws.
KEYLESS CHUCK - FIGURE 6
To insert a drill bit or other accessory:
1. Grasp the chuck collar with one hand and use your other hand to rotate the chuck in
the counterclockwise direction, as viewed from the chuck end.
2. Insert the bit or other accessory fully into the chuck, and tighten securely by holding
the rear portion of the chuck and rotating the front portion of the chuck in the
clockwise direction as viewed from the chuck end.
WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the
front part of the chuck and turning the tool on. Damage to the chuck and personal
injury may occur when changing accessories.
DUAL RANGE GEARING - FIGURE 7
The dual range feature allows you to shift gears for greater versatility.
• To select low speed, high torque setting (position 1), turn tool off and permit to stop.
Slide gear shifter button (J) back (away from chuck).
• To select the high speed, low torque setting (position 2), turn tool off and permit to
stop. Slide gear shifter button forward towards the chuck. NOTE: Do not change gears
when tool is running. If you are having trouble changing gears, make sure that the
gear shifter button is either completely pushed forward or completely pushed back.
SCREW DRIVING
For driving fasteners, the reversing button should be pushed to the left. Use reverse
(button pushed to the right) for removing fasteners. When moving from forward to
reverse, or vice versa, always release the trigger switch first.
DRILLING
Use sharp drill bits only.
Support and secure work properly, as instructed in the Safety Instructions.
Use appropriate and required safety equipment, as instructed in the Safety
Instructions.
Secure and maintain work area, as instructed in the Safety Instructions.
Run the drill very slowly, using light pressure, until the hole is started enough to keep
the drill bit from slipping out of it.
Apply pressure in a straight line with the bit. Use enough pressure to keep the bit biting
but not so much as to stall the motor or deflect the bit.
Hold the drill firmly with two hands to control its twisting action.
