observe the following safety
precautions and warnings. Careless
or improper use of tool may cause
serious or fatal injury.
WARNING! Indicates instant
possibility of severe personal
injury or loss of life, if instructions
are not followed.
Always wear eye, head and ear
protectors when using this tool.
SAFETY FIRST
InDeX
CAUTION! Indicates possibility
of personal injury or equipment
damage, if instructions are
not followed.

Work Area
Keep your work area clean and well lit. Cluttered benches and
dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as
in the presence of ammable liquids, gases or dust. Power tools
create sparks which many ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a
power tool. Distractions can cause you to loose control.
Operator Safety
• Always wear a safety face shield or goggles.
• Always wear heavy, long pants, boots and gloves. Do not wear
loose clothing, jewelry, short pants, sandals or go barefoot.
Secure hair so it is above shoulder length.
• Do not operate the tool when you are tired, ill or under the
inuence of alcohol, drugs or medication.
• Never let a child or inexperience person operate the machine.
• Wear hearing protection.
• Never start or run the engine inside a closed room or building.
Breathing exhaust fumes can kill.
• Keep handles free of oil and fuel.
• Keep hands away from anvil.
• Do not grab or hold the unit by rotating anvil.
• Hold the handles rmly with both hands and make sure to stand
on a rm base or ground.
• Do not touch spark plug or high voltage cord during operation
as it may cause electric shock.
• To avoid burn do not touch those places like engine, mufer
and exhaust. These parts get very hot during use, even after
engine is stopped.
• When operation is prolonged, take a break from time to time, so
that you may avoid possible whitenger disease. This is
caused by vibration.
Tool Safety
• Inspect the entire tool before each use. Replace damaged parts.
Check for fuel leaks and make sure all fasteners are in place and
securely fastened.
• Replace parts that are cracked, chipped or damaged in any way
before using the tool.
• Keep others away when making carburetor adjustments.
• Use only accessories as recommended for this tool by the
Manufacturer.
Fuel Safety
• Mix and pour fuel outdoors and where there are no sparks
or ames.
• Use a container approved for fuel.
• Do not smoke or allow smoking near fuel or the tool or
while using the tool.
• When lling up fuel, stop engine and make sure engine is cool
and choose a well ventillated place where no amables are
present. 3

MAINTENANCE / CHECK-UP / REPAIRING
It is recommended to practice regular check-ups and maintenance in accordance with usage frequency to keep
your tool in its best condition and prolong life, reducing total running costs. This practice also protects you from
serious injury. Before maintenance, please release the start and stop device.
• Only use #10 lubricant, the tool should be lubricated at tool inlet.
• Do not replace the component or change the construction and design.
• If the component used is not the same as the original component supplied by the manufacturer,
the manufacturer shall not take responsibility.
• Keep the tool in a dry place when not in use.
DAILY CHECK-UP
• Check that all nuts and screws are securely tightened.
• Check fuel level. When lling up with fresh fuel, wipe up all spills and clean fuel tank.
• Check oil level of gear box through window. Oil level should be at the center of window. If lower than this
level, add oil.
WEEKLY MAINTENANCE
• Check the starter, especially the cord and return spring.
• Clean the exterior of the spark plug.
• Remove the spark plug and check the electrode gap. Adjust it to 0.6mm, or change the spark plug.
• Clean the cooling ns on the cylinder and check that the air intake at the starter is not clogged.
• Clean the air lter.
MONTHLY MAINTENANCE
• Rinse the fuel tank with gasoline.
• Clean the exterior of the carburetor and the space around it.
• Clean the fan and the space around it.
1. CARBURETOR ADJUSTMENT
1. When the engine is tested at the factory, the carburetor is properly adjusted.
Do not try to touch it.
2. When idle speed is higher or lower (engine will stop), adjust to correct speed
by idle adjustment screw. Turn clockwise for higher idle. Turn counter clock
wise for lower idle. (Fig. 5-1).
3. How to adjust the volume of inhaled oil (higher speed fuel adjustment)
Full open throttle lever, turn idle adjustment screw to right or left to look for the
peak idle speed. From this position, return adjustment screw to left 1/8-1/4 turn.
2. CHECK-UP SPARK CONDITION
1. Remove spark plug and touch it to metal part except spark plug mounting thread.
2. Pull recoil starter handle.
3. When in normal condition, you see a spark.

WARNING
Never touch spark plug to the area at spark plug mounting

WARNING
When pulling recoil starter handle, do not touch the metal part of
spark plug or you will get an electric shock.
Wipe and clean up fuel around spark plug area.

MAINTENANCE INSTRUCTIONS
3. SPARK PLUG (Fig. 5-2)
1. Use only recommended type of spark plug.
2. In best operating condition, electrodes on the spark plug are dark brown.
Keep spark plugs dry. If the spark plug is dirty, clean it and check electrode gap.
If readjustment is necessary, the correct gap is 0.6mm.
The spark plug condition is inuenced by the following factors:
• An incorrect carburetor setting.
• Wrong fuel mixture (too much oil in gasoline).
• A dirty air lter.
• Hard running conditions (cold weather operations).
The spark plug should be replaced after 100 operation hours or earlier if the electrodes
are badly eroded.
4. AIR FILTER (FIG. 5-3)
1. When the air lter gets dirty and closed with dust, it will cause various troubles:
• Carburetor malfunctions.
• Starting problems.
• Engine power reduction.
• Unnecessary wear on engine parts.
• Abnormal fuel consumption.
2. Cleaning the air lter
Air lter must be cleaned from dust and dirt regularly and
damaged lter must be replaced with a new one.
• Remove the air lter cover and the lter.
• Rinse it in warm soapy water and wring tight. Let dry
before re-assembly.
• Damaged air lter must be replaced with a new one.
5. FUEL FILTER (Fig. 5-4)
1. If fuel lter is clogged with impurities in the fuel, fuel will
not ow into carburetor and it will make the engine
malfunction. Regular check-ups is recommended.
• Drain all fuel from fuel tank and pull out fuel lter
line from tank.
• Pull lter element out of holder assembly and rinse
element in warm water with detergent.
• Rinse thoroughly until all traces of detergent
are eliminated.
• Squeeze, but do not wring and let dry.
• If element is too dirty, replace.
6. MUFFLER (Fig. 5-5)
1. Engine power reduction might be caused by carbon
accumulation around the exhaust port on cylinder,
mufer inlet or outlet in the long use. Regular
clean-up is recommended.
• Remove the mufer and clean up any excess
carbon from the exhaust port or mufer inlet
every 100 hours of operation.
• When cleaning up, remove carbon carefully to not
damage piston. cylinder and do not let carbon into
crank case.

MAINTENANCE INSTRUCTIONS
7. IMPACT MECHANISM
1. When contact places of anvil and hammer become worn-out by percussion, the tool becomes susceptible
to damage and can lead to breakage of parts.
• Empty all oil in the gear box and remove hammer housing completely and check the degree of
worn-out on anvil and hammer at least once every month. Grease around hitting area.
8. ADDING OIL
1. Use of the correct hydraulic oil is essential. Approved oils are Shell "TELLUS Oil" and Exxon
"TERESSTIC" (Part No. 75377). Grade #32 viscosity must be used. Check the unit specications. Make
sure that the work area and all equipment are clean so that no dirt, dust or other foreign material can get
into the hydraulic oil or pump area.
2. Remove Anvil plug (reference part no. 229 on page 16) and ll with #75377 Hydraulic oil.
3. Replace the Anvil plug and wipe up any excess oil.
9. STORAGE
1. Clean each part and apply two cycle oil on the metal part to prevent corrosion.
2. To keep tool for a long time (more than 3 weeks), drain fuel from fuel tank and keep running
engine without load until the engine will stop and exhaust all remaining fuel in the carburetor.
3. Remove spark plug and pure two cycle oil into cylinder and pull recoil starter handle several
times to spread oil.
4. Stop the recoil starter handle when you feel engagement.
5. Damaged parts should be repaired before storage.
6. Keep the tool in a place without dust or humidity, also the temperature below 50˚ C.
7. Store tool out of reach of children.
8. Keep fuel in safety container in a cool room or place where not ammable. Do not use
stale fuel as it cause engines troubles.
