OPERATING
INSTRUCTIONS
NOTE:
Before using the tool, read the
instruction book carefully.
1. AUXILIARY HANDLE (See Fig. A)
Slide the handle onto the drill and rotate to the desired
working position. To clamp the auxiliary handle rotates the
handgrip clockwise. To loosen the auxiliary handle rotates
the handgrip anti-clockwise. Always use the auxiliary
handle.
2. INSTALLING THE DEPTH GAUGE
(See Fig. A)
The depth gauge can be used to set a constant depth to
drill. To use the depth gauge, loosen the handle by rotating
the bottom section of handle anti-clockwise. Insert the
depth gauge through hole in handle. Slide the depth gauge
to required depth and tighten fully.
3. CHUCK ADJUSTMENT (See Fig. B)
When mounting the drill bit, insert bit between the chuck
jaws as far as it will go. Ensure drill bit is in the center of the
chuck jaws. Using the chuck key provided, there are three
holes in which the chuck key should be inserted. Tighten
them equally in turn at each of the three holes, not just at
one hole. Your drill bit is now locked in the chuck. The bit
can be removed by reversing the above procedure.
4. ON/OFF SWITCH
Depress the switch to start the tool and release it to stop
your tool.
5. SWITCH LOCK-ON BUTTON (See Fig. C)
Depress on/off switch then lock-on button, release on/off
switch first and lock-on button second. Your switch is now
locked on for continuous use. To switch off your tool just
depress and release the on/off switch.
6. VARIABLE SPEED SWITCH (See Fig. D)
Adjust the variable speed switch to increase or decrease the
speed according to the material and accessory to be used
(also possible during no load operation). Low speed will
provide low torque and high speed gives higher torque.
7. FORWARD AND REVERSE ROTATION
CONTROL (See Fig. E)
For drilling use forward rotation marked “ ” (lever is
moved to the left). Only use reverse rotation marked “ ”
(lever is moved to the right) to release a jammed drill bit.
Note: Never move the forward/reverse switch
whilst the drill in operation or the on/off
switch is locked as this will damage the drill.
8. HAMMER OR DRILLING CONTROL (See
Fig. F)
When drilling masonry and concrete choose the hammer
position “ ”. When drilling in wood, metal and plastic,
choose the drill position “ ”.
WORKING HINTS FOR
YOUR IMPACT DRILL
1. Drilling masonry and concrete
Select the drill/impact action selector switch to the
“hammer symbol” position. Tungsten carbide drill bits
should always be used for drilling masonry, concrete etc
with a high speed.
2. Drilling steel
Select the drill/impact action selector switch to the “drill
symbol” position. HSS drill bits should always be used for
drilling steel with a lower speed.
3. Pilot holes
When drilling a large hole in tough material (i.e. steel), we
recommend drilling a small pilot hole first before using a
large drill bit.
4. Drilling tiles
Select the drill/impact action selector switch to the “drill
symbol” position to drill the tile. When tile has been
penetrated, switch over to “hammer symbol” position.
5. Cool the motor
If your power tool becomes too hot, set the speed to
maximum and run no load for 2-3 minutes to cool the motor.
MAINTENANCE
Remove the plug from the socket before
carrying out any adjustment, servicing or
maintenance.
There are no user serviceable parts in your power tool.
Never use water or chemical cleaners to clean your power
tool. Wipe clean with a dry cloth. Always store your power
tool in a dry place. Keep the motor ventilation slots clean.
Keep all working controls free of dust. Occasionally you may
see sparks through the ventilation slots. This is normal and
will not damage your power tool.
If the supply cord is damaged, it must be replaced by
the manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
