Safety Information
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 of the warnings listed below refers to your mains operated (corded) power tool or
battery operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1. WORK AREA
a. Keep work area clean and well lit.
Cluttered and dark areas invite accidents.
b. Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust.
Power tools create sparks which may ignite the dust of fumes.
c. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2. ELECTRICAL SAFETY
a. Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and
refrigerators.
There is an increased risk of electric shock if your body is earthed or grounded.
c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
d. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e. 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.
3. PERSONAL SAFETY
a. Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool white you are tired or under the influence of drugs, alcohol or medication.
A moment of inattention while operating power tools may result in serious personal injury.

b. Use safety equipment.
Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hardhat, or
hearing protection used for appropriate conditions will reduce personal injuries.
c. Avoid accidental starting. Ensure the switch is in the OFF position before plugging in.
Carrying power tools with your finger on the switch or plugging in power tools that have the switch on
invites accidents.
d. Remove any adjusting key or wrench before turning the power tool on.
A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
e. Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f. 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.
g. If devices are provided for the connection of dust extraction and collection facilities, ensure
these are connected and properly used.
Use of these devices can reduce dust related hazards.
4. POWER TOOL USE AND CARE
a. Do not force the power tool. Use the correct power tools for your application.
The correct power tool will do the job better and safer at the rate for which it was designed.
b. 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.
c. Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing power tools.
Such preventive safety measures reduce the risk of starting the power tool accidentally.
d. Store idle power 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.
e. 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 using it. Many accidents are caused by poorly
maintained power tools.
f. Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to
control.
g. Use the power tool, accessories and tool bits etc., 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.
PRECAUTION
Keep children and infirmed persons away. When not in use, tools should be stored out of reach of
children and infirmed persons.

Precautions on Using the Electric Jackhammer
•
Wear ear protections. Exposure to noise can cause hearing loss.
•
Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
•
Do not touch the bit during or immediately after operation. The bit becomes very hot during operation and
could cause serious burns.
•
Before starting to break, chip or drill into a wall, floor or ceiling, thoroughly confirm that such items as electric
cables or conduits are not buried inside.
•
Ensure the trigger is not engaged when plugged into power. Trigger can be engaged even when not holding
the device by the trigger lock!
•
Wear a mask when turning your head upward.
•
Properly set the bit holder
•
At the start of your work, confirm that all of the screws have been properly tightened.
•
When working at a highly elevated location, pay close attention to objects and people below.
•
Wear protective shoes to protect your feet.

Adjusting the Handle
Loosen the 6mm hex screw (circled in red, left – one on
each side) with provided allen key.
Turn handle to preferred side (left or right)
Using the Jackhammer
1. Squeeze the trigger switch after applying the tip of the bit to the crushing position.
In some cases, it is necessary to punch the tip of the bit against the crushing position forcibly in order to
begin the striking motion.
This is not due to malfunction of the tool. It means that the safe guard mechanism against no-load striking is
working.
2. Operate the tool by utilizing its empty weight.
The performance will not be better even if the tool is pressed or trust forcibly against the work surface.
Hold the tool with a force just sufficient to counteract the reaction
3. To use the trigger lock, squeeze trigger and then press in the lock pin. Please be very careful when using
this feature! This is intended for extended periods of time. To disengage pin, squeeze trigger (this will make
the pin pop back out) and release trigger.
ALWAYS ENSURE TRIGGER IS DISENGAGED WHEN TURNING OFF AT THE MAINS POWER!
Maintenance and Inspection
Be sure to switch OFF and disconnect the power plug to avoid a serious accident.
1. Inspecting the tool
Since use of a dull tool will degrade efficiency and cause possible motor malfunction, sharpen or replace the
tool as soon as abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so could result in serious hazard.
3. Checking gear oil level/Refilling gear oil
Ensure jackhammer is exactly vertical/upright and check level.
Will need refilling if at level in red box

4. Refilling gear oil
Ensure jackhammer is laid down fully flat. Remove cap with provided hex spanner. Recommended gear oil
to use is 75W-90W SAE grade. Depending on usage, this should be done after every 50 hours of usage.
5. Maintenance of the motor
The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does
not become damaged and/or wet with oil or water.
6. Inspecting the carbon brushes
The Motor employs carbon brushes which are consumable parts. When they become worn to or near the
“wear limit” (Approx. 7mm), it can result in motor issues. The motor may stop automatically or intermittently
7. Replacing carbon brushes
Remove screws and cover. Remove rubber O ring. Unscrew cap with 5c or 10c piece (or large flat blade
screw driver). Remove carbon brush and replace.
