Preface
Thanks for buying the Electric Jackhammer, another high-quality machine from our company. To get the most
out of your purchase, please read the manual before use.
We ask you to please read this manual carefully beforehand in order to familiarise yourself with this product and
after reading, please store this instructional manual for future reference. Failure to follow the proper protocols
listed in the manual may cause personal injury to the operator or damage to equipment.

Safety Information
Failure to follow the instructions listed below may result in electric shock, fire and/or serious injury.
The term “power tool” in all of the information listed below refers to the Jackhammer.
•Work Area
−Keep the working area clean and well lit.
−Do not operate the power tool in the presence of flammable liquids, gases or dust.
−Keep children and bystanders away while operating the power tool. Keep the area free of all distractions.
•Electrical Safety
−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 the risk of electric shock.
−Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of
electric shock.
−Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep the
cord away from heat, oil, sharp edges or moving parts.
Do not use the power tool if it has a damaged or entangled cord.
−When operating a power tool outdoors, use an extension cord suitable for outdoor use. A suitable cord
will reduce the risk of electric shock.
•Personal Safety
−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 any power tools may result in serious personal injury.
−Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal
injuries.
−Always wear earplugs to protect your ears.
−Avoid accidental starting. Ensure the switch is in the off position before plugging it in. Carrying power
tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.
−Remove any adjusting key or wrench before turning the jackhammer on. A wrench or a key left attached
to a rotating part of the power tool may result in injury.
−Do not overreach. Keep proper footing and balance at all times. This enables better control of the power
tool in unexpected situations.
−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.
−If devices are provided for the collection of dust extraction, ensure these are connected and properly
used. Use of these devices can reduce dust related hazards.

−Do not touch the bit during or immediately after operation. The bit becomes very hot during operation
and can cause serious burns.
•Power Tool Use and Care
−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 for which it was designed.
−Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
−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.
−Do not allow anyone who is unfamiliar with the jackhammer to operate it. Power tools are dangerous in
the hands of untrained users.
−Properly keep and maintain your power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect operation. If damaged, have the power tool
repaired before use. Many accidents are caused by poorly maintained power tools.
−Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
−Use the power tool 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.
−Using the power tool for operations different from its intended use could result in hazardous situations.
•Service
−Have your power tool serviced by a qualified repair person using only original replacement parts.
Precautions on Using the Jackhammer
•Wear protective glasses to protect your eyes.
•Wear a mask when turning your head upwards.
•Use earplugs to keep your ears noise-free while working.
•Set the bit holder properly.
•Since the bit becomes very hot during operation, exercise extreme caution when you are near it.
•Be sure to use the side handle.
•Safe operation depends on one’s stable posture.
•At the start of each work, check the oil supply and tighten any loose screws.
•When working at a highly elevated location, pay attention to objects and persons that are below you.
•Before starting to break or chip a wall, floor, or ceiling, confirm thoroughly that no items such as electric
cables or conduits are buried inside.
•Wear protective shoes to protect your feet.

Prior to Operation
•Power Source
Ensure that the power source to be utilised conforms to the power requirements specified on the product
nameplate.
•Know what’s below
Before starting to break, chip or drill into a floor, thoroughly confirm that there is no underground utilities
running underneath including cables and pipes.
•Power Switch
Ensure that the power switch is in the off position. If the plug is connected to a receptacle while the power
switch is in the on position, the power tool will start operating immediately which could cause a serious
accident.
•Extension cord
Use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short
as possible.
•Tool Mounting
Clean then, smear the tool shank with grease or machine oil (Fig. 1). Rotate the stop lever 180, in clockwise
direction while pulling it toward you. Next, insert the tool shank into the hexagonal hole on the front cover
(Fig. 1). Clamp the tool by turning the stop lever by half a turn in the opposite direction (Fig. 2).

How to Use 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. It means that the safe guard mechanism against no-load striking is working.
2. Operate the tool by utilising its empty weight. The performance will not improve even if the tool is pressed or
thrust forcibly against the work surface. Hold the tool with a force just sufficient to counteract the reaction
(Fig. 3).
Maintenance and Inspection
•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 you note an abrasion
•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 hazardous situations.
•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.
•Inspecting the carbon brushes
The motor employs carbon brushes which are designed to be replaceable. When they become worn or near
the ‘wear limit’, it may result in motor trouble. When an auto-stop carbon brush is equipped, the motor will
stop automatically. At that time, replace both carbon brushes, as shown in Figure 4. In addition, always keep
carbon brushes clean and ensure that they slide freely within the brush holders.
•Replacing carbon brushes
Loosen the screws of the cap covers, then remove the cap covers (Fig. 5). After removing the brush caps,
the carbon brushes can be removed. After replacing the carbon brushes, tighten the brush caps, and mount
the cap covers securely.
•Grease Replacement
The jackhammer has been constructed to protect against dust and to prevent lubricant leakage. Whilst the
unit can be used without lubricant for an extended period, we recommend not allowing it to run dry. Use a
spanner to remove the hexagonal sight glass. Add 75W-90W SAE grade oil or something similar. Reinsert
sight glass.
NOTE: Be sure to switch OFF and disconnect the attachment plug from the receptacle to avoid serious
accidents.
