IMPORTANT SAFETY INFORMATION
2
Avoid unintentional starting. Prepare to begin work before turning on the tool.
DO NOT lay the tool down until it has come to a complete stop. Moving parts can grab the surface and pull
the tool out of your control.
When using a hand-held power tool, maintain a firm grip on the tool with both hands to resist starting
torque.
Tool service must be performed only by qualified repair personnel. Service or maintenance performed
by unqualified personnel could result in a risk of injury. For example: internal wires may be misplaced or
pinched, safety guard return springs may be improperly mounted.
DO NOT use dull or damaged bits and accessories. Dull or damaged bits have a greater tendency to bind
in the work-piece.
When operating this power tool, use the weight of the tool to do most of the work. The should be reasonable
in order to achieve high efficiency and easier operation.
DO NOT use this tool to pry apart stone. This tool should be used for crushing, tamping and compacting
work.
Ensure the handles are free of grease and water.
Double check all screws are tightened prior to using the machine. If any are found, re-tighten immediately.
Quick acceleration and fast stopping is not recommended as it may cause damage to the machine.
Avoid fragmentation impact on the tool by not using the highest speed available. Moderate speeds should
be used for this.
People with pacemakers should consult their physician(s)
before use. Electromagnetic fields near heart
pacemakers could cause pacemaker interference or pacemaker failure. In addition, people with pacemakers
should: • Avoid operating alone. • Properly maintain and inspect to avoid electrical shock. • Properly
ground power cord. Ground Fault Circuit Interrupter (GFCI) should also be implemented, it prevents
sustained electrical shock. Wear ear protectors. Exposure to noise can cause hearing loss.
Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a ″live″ wire will make exposed metal parts of the tool ″
live″ and shock the operator.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
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.
Only use safety equipment that has been approved by an appropriate standards agency.
Unapproved safety equipment may not provide adequate protection. Eye protection must be ANSI-
approved and breathing protection must be NIOSH-approved for the specific hazards in the work area.
If devices are provided for the collection of dust extraction and collection facilities, ensure these
are connected and properly used. Use of these devices can reduce dust-related hazards.
Dress properly. DO NOT wear loose clothing or jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
DO NOT overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.

OPERATION
1. Power Source: Ensure that the power source to be utilized conforms to the power requirements specied
on the product nameplate.
PRIOR TO OPERATION
2. Grounding: This tool should be grounded while in use to protect the operator from electric shock. The tool
is equipped with a three conductor cord and grounding type plug to t the proper grounding type receptacle.
The green or green and yellow conductor in the cord is the grounding wire. NEVER connect the green (or
green and yellow) wire to a live terminal.
3.
Power Switch: Ensure that the power switch is in the OFF position. If the plug is connected to a power
receptacle while the power switch is in the ON position. The power tool will start operating immediately. Use
caution.
4.
Extension Cord: When the work area is a distance away from the power source, ONLY use an extension
cord that is sufcient thickness and rated capacity. The extension cord should be kept as short as practical.
5.
Mounting a Tool: When handling a bull point or cold chisel bit, rotate the stop lever 180 degrees in a
clockwise direction while pulling it towards you. Next, insert the tool shank into the hexagonal hole on the
front cover. Next, clamo the tool by turning the stop lever half a turn on the opposite direction.
NOTE: When removing the tool, follow the above procedure in reverse order.
USING THE HAMMER
1. After placing the tip of the tool in the base hold switch ON. In some cases, it is necessary to punch the
top of the bitagainst the crushing position forcibly in order to begin striking the stroke. This is not due to a
malfunction of the tool, it means the safe gaurd mechanism against no-load striking is working.
2.
By utilizing the weight of the machine and by rmly holding the hammer with both hands. One can effectively
control the subsequent recoil motion. Proceed at a moderate work rate. The use of too much will impair
efciency.
CAUTION: Sometimes the tool does not begin the striking stroke even when the motor rotates because the
oil has become thick. If the tool is used in low temperatures or if it is used after extended idle time, the tool
should be ran for 5 minutes to warm up before using the tool.
PRECAUTIONS
1. Wear protective glasses to protect your eyes.
2. Wear a mask to keep dust away and ear plugs to protect your ears
3. Properly set the Bi-Holder
4. The bit becomes very hot during use, excercise extreme caution when using the bit.
5. Be sure to use the side handle when using the hammer.
6. At the start of work, conrm the oil supply and screws tightened.

OPERATION AND MAINTENANCE
OIL FEEDING
CAUTION: Prior to oil feeding, ALWAYS disconnect the plug from the power source. Since the oil chamber
is built in, the hammer can be used for approximitely 20 days before needing resupplied with lubricating oil.
(Used continuosly at 3-4 hours daily). Feed oil into the tanl as described below before using the hammer.
1. Feed with oil when you can see that just before no oil is visible in the oil gauge window then the tool is
held upright.
2. Before feeding oil, use the provided wrench to remove the oil gauge. Be careful not to lose the rubber
packing that is attached below the oil gauge.
3. Check the oil level once daily to conrm the oil is appropriately lled.
4. After feeding with oil, securely clamp the oil gauge.
NOTE: As an optional accessory, the oil in the tank is depleted. Shell Oil Co. Rotella #40 engine oil can also
be used.
MAINTENANCE AND INSPECTION
1. INSPECTING THE TOOL: Using a dull tool will inevitably cause motor to malfunction and degrade
efciently. Replace the dull tool with a new one immediately once abrasions or wear are noted.
2. INSPECTING MOUNTING SCREWS: Regularly inspect all mounting screws and ensure that they are
properly tightened. Should any of the screws be loose, retighten immediately. Failure to do this can result in
serious injury.
3. MAINTENANCE OF THE MOTOR: The motor unit winding is the heart of the power tool. Take care to
ensure due care the winding does not become damaged and or wet with oil or water.
4. INSPECTING THE CARBON BRUSHES: The motor employs carbon brushes which are consumable
parts. When they become near their wear limit, it can result in motor trouble. When the auto-stop carbon
brush is equipped the motor will stop automatically. At that time, replace both carbon brushes with new ones
that are identical. ALWAYS keep the carbon brushes clean and ensure they slide freely within the brush
holders. The carbon brush can be removed by removing the cap cover. Cap rubber and brush cap in that
order at the interior.
NOTE: Due to continuing program of research and development. The specications herin are subject to
change without prior notice.
