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 with your other
hand. Ensure the chuck is firm and the jaws have clamped evenly around
the drill bit.
You may need to occasionally check the tightness of the chuck during
drilling as it may vibrate loose.
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.
Adjusting Between Hammer and Drill Mode
The mode selector indicates the hammer and drill mode by 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.
Operation
Depress and release the switch to make sure the switch is not locked on before
connecting it to a power supply.
Check the rotation lever for the correct setting.
Secure the material to be drilled in a vice or with clamps to stop it from turning as
the drill rotates.
Plug the hammer drill into a power supply.
Hold the drill firmly and place the bit at the point to be drilled.
