Operation
WARNING - Before working, allow the drill to operate for at least one
minute without load.
Installing and changing drill bits
1. Clean the slivers and any other foreign objects away from the bit and
chuck, otherwise the bit might not be tightened securely and can induce
severe personal injuries.
2. Insert the bit into the chuck, making sure that the bit is in as far as it
will go. Warning: The length of the drill bit within the drill chuck must
be at least 1/3 of the general length.
3. Place the chuck key in each of the 3 holes, then tighten all three jaws
of the chuck by rotating the chuck key clockwise.
4. To change the drill bit, loosen the 3 jaws with the chuck key, then
remove the old drill bit, and insert a new one.
Note: Always remove chuck key from the holes before starting drill
Lock-on button
The drill is equipped with a “lock-on” button that is convenient when
continuous drilling for extended periods of time is required.
1. Press down trigger switch to start work, and release to stop work.
2. To have continuous operation, press down the trigger switch and push
the lock-on button locked on the side of the handle, then release trigger.
3. The drill will continue running after release of the lock-on button. To
stop working, release the trigger switch.
Selecting the correct operating speed
• The tool can be operated at different speeds, changed by a speed control
adjuster on the switch. Hold the drill in normal operation position, and
turn the variable speed control selector clockwise to increase the speed
and torque of the drill. Turn counter-clockwise to decrease the speed and
torque.
