2. Close the air vent when the engine is cool. You can open the air vent only when the engine is hot.

3. Hold the handles using one of your hands and quickly pull the pull start for about 50cm with the other hand.

Do not let go of the pull start while you are repeatedly pulling it. Hold it and put it down gently to protect the

starter.

4. Open the air vent completely when the engine has started.

Running

1. After the engine has started up, warm it up in low speed first for about 2 to 3 minutes.

2. When the engine is warm enough, use the jackhammer according to the required impact energy of the job.

NOTE: For the first 24 hours, work load should be light at first. Do not accelerate the engine quickly if you

have just lube it with petrol.

3. Select a medium speed first to run the engine, pulling the control between the scales of 3 – 4.

4. Do not use the jackhammer in high speed operation for prolonged periods of time.

Stopping the Jackhammer

1. Put the switch to the ‘0’ position and let the engine run idle for 3 – 5 minutes.

2. Press the red STOP button to stop the jackhammer.

Maintenance

Air Filter

Check the air filter regularly. Dust blockage on the air filter cover can reduce the engine’s power and can shorten

the engine’s service life. If the air filter is very dirty, clean it with a soft, clean cloth that has been mixed with a

mild detergent in warm water. After cleaning the air filter and letting it air-dry, lubricate it with a few drops of oil

and then re-install it in the jackhammer. The air filter should be replaced if it is already damaged, particularly if

the environment is very dirty/dusty and could shorten its maintenance cycle.

Fuel Filter

If the fuel filter is clogged, it will slow down the jackhammer’s speed and force impact.

1. Open the tank lid with a metallic hook, then take out the fuel filter and clean it.

2. When cleaning the fuel filter, please also clean the fuel tank.

Carburettor

The fuel tank and carburettor generally have left-over residual oil on them. If a prolonged period has passed, the

residual oil can coagulate and cause blockades to the oil line, causing the engine to not work. Therefore, when

the jackhammer is not used for more than a week, ensure that you completely drain out the oil.

To drain out the oil, press the carburettor fuel primer bulb repeatedly.

Spark Plug

To ensure normal operations of the engine, the spark plug’s gap should be moderately spaced. Use a wire brush

to remove any sediments, if needed. A reasonable spark plug gap is between 0.5 – 0.7mm.

Muffler

Use a screwdriver to remove dirt/debris on the muffler and on the exhaust.

Centrifugal Oil Cup

Open the gear box cover to check on the centrifugal oil cup and add oil regularly, as needed.

Cylinder Heat Sink

Remove dust and debris regularly to ensure proper cooling of the cylinder. The jackhammer is air-cooled, if

dust/debris is allowed to accumulate on the heat sink, it will directly affect the cooling rate of the cylinder.
