OPERATION (cont.)
Chuck
Inserting Bits
Open the jaws slightly larger than the bit you are inserting. Insert the drill
bit up to the flutes making sure it is centred in the jaws. Tighten the chuck
by holding the rear of the chuck and rotating the front sleeve with your
other hand. Ensure the jaws of the chuck have clamped evenly around the
drill bit or accessory.
Periodically check that the jaws of the chuck are secure as they may
vibrate loose during operation.
On/Off Switch
To turn the tool “On” depress the On/Off switch. The tool can be locked on by first
depressing the On/Off switch and then the lock on button. Once the lock on
button has been pushed in, the switch will remain locked on.
To turn the tool “Off”, release the switch. To turn the tool “Off” when the lock on
button is engaged, simply squeeze and release the switch.
Your drill is also provided with a Speed Selection Dial, this is used to pre set any
required speed by turning the dial. Once you have set the dial you are then limited
to the speed range of 0 to the speed selected.
Forward/Reverse Lever
The direction of the chuck is controlled by the forward/reverse lever located above
the switch.
FOR FORWARD ROTATION: Move the lever to the left.
FOR REVERSE ROTATION: Move the lever to the right.
Note:
Do not change the direction of rotation while the chuck is still in motion.
Carbon Brushes
The hammer drill is fitted with a brush wear indicator light. A green light shows
brushes are operating correctly. A red light shows brushes need to be checked and
possibly be replaced.
Adjusting Between Hammer and Drill Mode
The mode selector indicates the hammer and drill mode by utilising two separate
icons. The hammer icon indicates hammer mode. The drill bit icon indicates drill mode.
Note:
When drilling in hammer mode, carbide tipped drill bits should be used and
the drill must be set in forward rotation.
