SAFETY PRECAUTIONS
WORK AREA
1. Keep work area clean and well lit. Cluttered and dark areas invite
accidents.
2. DO NOT operate power tools in explosive atmospheres, such as in the
presence of flammable liquids or gases. Power tools can create sparks
which may ignite the fumes.
3. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. AVOID body contact with earthed or grounded surfaces such as pipes,
radiators, ranges or refrigerators. There is an increased risk of electric shock
if your body is earthed or grounded.
2. DO NOT expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
3. When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
PERSONAL SAFETY
1. ONLY hold the tool using the handles when in use. DO NOT attempt to use
the tool with one hand.
2. Stay alert, watch what you are doing and use common sense when
operating a power tool. DO NOT use a power tool while you are tired or
under the influence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in personal injury.
3. ALWAYS use safety equipment. Safety equipment such as dust mask, non-
skid safety shoes and hearing protection used for appropriate conditions
will reduce personal injuries.
4. AVOID accidental starting. Ensure the switch is in the off position before
connecting to the power supply.
WARNING: READ ALL INSTRUCTIONS. FAILURE TO FOLLOW ALL
INSTRUCTIONS LISTED BELOW MAY RESULT IN ELECTRIC SHOCK, FIRE AND/
OR SERIOUS INJURY. THE TERM “POWER TOOL” IN ALL WARNINGS LISTED
BELOW REFERS TO YOUR DEMOLITION HAMMER.

5. DO NOT overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
6. Dress properly. DO NOT wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts. ALWAYS use protective clothing
for prevention of injury.
7. All hand held power tools vibrate to some extent, and this vibration is
transmitted to the operator via the handles. Operators who are regularly
exposed to vibration may suffer from Hand Arm Vibration Syndrome
(HAVS), which includes ‘dead hand’, ‘dead finger’, and ‘white finger’.
These are painful conditions and are widespread in industries where
vibrating tools are used. If you feel numbness or pain in hands or arms, STOP
using the tool and take a rest. If symptoms persist seek medical advice.
POWER TOOL USE AND CARE
1. DO NOT force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at the
rate which it was designed.
2. DO NOT use the power tool if the switch does not turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and
must be repaired.
3. Disconnect the power before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
4. Store idle tools out of the reach of children and DO NOT allow persons
unfamiliar with the power tool or these instructions to operate the power
tool. Power tools are dangerous in the hands of untrained users.
5. Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power
tools operation. If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Poorly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool and accessories in accordance with these instructions
and in the manner intended for the particular type of power tool, taking
into account the working conditions and the work to be performed. Use of
the power tool for operations different from intended could result in a
hazardous situation.

SERVICE
1. Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.

BEFORE USE
OIL GAUGE/OIL TOP UP
This machine has an oil chamber built in. The machine can be used for
approximately 20 days without resupplying the lubrication oil, assuming that
the hammer is used continuously for 3-4 hours daily. Check the oil level before
every use.
Check oil level by standing the
machine upright and view the oil
level through the gauge window. If
low;
1. Place hammer on a flat surface
with the oil gauge window facing
upwards.
2. Using the wrench, remove the oil
gauge window cover.
3. Top up the oil well using the oil
bottle supplied. No more than 25ml at a time.
• DO NOT overfill the chamber.
4. Replace the oil gauge window cover and tighten with wrench before
using the hammer again.
POSITIONING THE AUXILIARY HANDLE
The front handle can be positioned
left, right or centre as required.
1. Loosen the handle adjustment
knob by twisting it clockwise.
2. Rotate the handle to the required
position.
3. Secure the handle by twisting the
handle adjustment knob
anticlockwise.
INSERTING A HAMMER BIT / CHISEL

180 degrees clockwise
3. Insert chisel into the chuck clamp
with the flat face of the chisel
facing the stop lever.
4. Pull out and rotate the stop lever
180 degrees anticlockwise to lock
the chisel in place.
5. Check by pulling the chisel to see if it is locked in place.
NOTE: Be aware that the hammer action requires the chisel to be able to
move axially by 2-3 cm.
6. To remove the chisel, reverse the above steps.
7. DO NOT allow dust or debris inside the chuck as this will cause problems in
the future
USING THE HAMMER
WARNING: ALWAYS CHECK OIL LEVEL BEFORE USE - SEE PAGE 8
BEFORE STARTING WORK
1. Before hammering into walls and floors etc., check first that there are no
hidden electrical cables, gas or water pipes etc.
2. Check the mains voltage (230v~50Hz) before plugging in and switching on.
3. Ensure the work area is as hazard free as possible.
STARTING WORK
1. Select and install the chisel to be used. See page 8.
2. If required, adjust the auxiliary handle for the most comfortable position,
see page 8.
• For safety, always use the hammer with the auxiliary handle attached.
CAUTION: WHEN REMOVING A BIT FROM THE HAMMER, REMEMBER THAT
IT MAY BE EXTREMELY HOT. EITHER ALLOW IT TO COOL DOWN FIRST OR
USE INDUSTRIAL GLOVES TO REMOVE THE BIT.

3. Position the tool against the
surface to be hammered and pull
the trigger switch.
4. For continuous use, press the
trigger lock button after pressing
the trigger.
STOPPING WORK
1. Release the trigger or press the trigger if in continuous use mode and wait
until the chisel has stopped before placing the hammer on any surface.
HAMMERING TIPS
• Always use sharp, good quality hammer bits/chisels. The performance of
your hammer is dependant on the quality of the bits used.
• Reduce the pressure on the hammer bit when it is about to break
through. This will prevent the hammer from jamming.
• If hammering a large hole, first hammer a pilot hole using a smaller
hammer bit.
• Always apply pressure to your hammer bit in a straight line.
MAINTENANCE AND SERVICING
1. After use, remove the hammer bit and tap the side of the chuck to remove
any dust or chippings etc.
2. Keep the handle clean and free from oil and grease.
3. Worn or damaged parts must be replaced by qualified personnel.
4. Clean the tool regularly, use a soft brush and/or soft cleaning cloth. DO
NOT use any chemicals or harsh abrasives to clean the tool.
5. At the end of work, to prevent dust deposits you should use compressed air
(max.3 bar) to clean out the ventilation holes. When using compressed air
ALWAYS wear the correct PPE and eye protection.
