Safety

Safety messages are designed to alert you to possible dangers or hazards that could cause death, injury or equipment or property damage if not understood or followed. Safety messages have the following symbols:

You WILL be KILLED or SERIOUSLY INJURED if you do not follow instructions.

It is vital that you read and understand this user manual before using the product, including safety warnings, and any assembly and operating instructions. Keep the manual for future reference.

Safety precautions and recommendations detailed here must be fully understood and followed to reduce the risk of injury, fire, explosion, electrical hazard, and/or property damage.

Safety information presented here is generic in nature – some advice may not be applicable to every product. The term "equipment" refers to the product, be it electrical mains powered, battery powered or combustion engine powered.

• Before Use - If you are not familiar with the safe operation/handling of the equipment or are in any way unsure of any aspect of suitability or correct use for your application, you should complete training conducted by a person or organization qualified in safe use and operation of this equipment, including fuel/electrical handling and safety.

• Do NOT operate the equipment in flammable or explosive environments, such as in the presence of flammable liquids, gases or dust. The equipment may create sparks or heat that may ignite flammable substances.

• Keep clear of moving parts.

• Equipment may be a potential source of

electric shock or injury if misused.

• Do NOT operate the equipment if it is damaged, malfunctioning or is in an excessively worn state.

• Do NOT allow others to use the equipment unless they have read this manual and are adequately trained.

• Keep packaging away from children - risk of suffocation! Operators must use the equipment correctly. When using the equipment, consider conditions and pay due care to persons and property.

General Work Area Safety

• Work areas should be clean and well it.

• Do not operate the equipment if

bystanders, animals etc are within operating range of the equipment or the general work area.

• If devices are provided for connecting dust extraction / collection facilities, ensure these are connected and used properly. Dust collection can reduce dust-related hazards.

You CAN be KILLED or SERIOUSLY INJURED if you do not follow instructions.

General Personal Safety

• Wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect from eye and ear injury, poisoning, burns, cutting and crush injuries. Protective equipment such as safety goggles, respirators, non-slip safety footwear, hard hat, hearing protection etc should be used for appropriate equipment / conditions. Other people nearby should also wear appropriate personal protective equipment. Do not wear loose clothing or jewellery, which can be caught in moving parts. Keep hair and clothing away from the equipment.

Starting

1. When you first start your jackhammer, press the fuel primer bulb repeatedly until the carburettor is filled with fuel.

Demolition Jackhammer

BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG

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.

Maintenance Cycle

The following data are given for common usage of the

jackhammer. If the jackhammer is exposed to bad

working conditions, i.e., thick dust in the air or very long

working hours, the maintenance cycle should be

shortened accordingly
