FUELS/REFUELING

Fuel and oil mixture

• The engine of the hedge trimmer is a high-efficiency two-stroke engine. It is run with a mixture of fuel and two-stroke engine oil. The engine is designed for unleaded regular fuel with a min. octane value of 91 ROZ.
  In case no such fuel is available, you can use fuel with a higher octane value.
  This will not damage the engine, but may cause poor operating behaviour.
  A similar situation will arise from the use of leaded fuel.
  To obtain optimum engine operation and to protect your health and the environment, only unleaded fuel should be used!

- For lubricating the engine use a two-stroke engine oil (quality grade: TSC-3), which is added to the fuel.

The engine has been designed for use with DOLMAR two-stroke engine oil and a mixture ratio of 50:1 only to protect the environment. In addition, a long service life and a reliable operation with a minimum emission of exhaust gases is guaranteed. It is absolutely essential to observe a mixture ratio of 50:1 (DOLMAR 2-stroke engine oil), otherwise the reliable function of the hedge trimmer cannot be guaranteed.

- The correct mixture ratio:

Gasoline: Specified two-stroke engine oil = 50 : 1 or

Gasoline: Other manufacturer's two-stroke engine oil = 25 : 1

recommended

NOTE: For preparing the fuel-oil mixture, first mix the entire oil quantity with half of the fuel required in an approved canister which meets or exceeds all local code standards. Then add the remaining fuel.

Thoroughly shake the mixture before filling it into the hedge trimmer's tank. Do not add more engine oil than specified to ensure safe operation. It will only result in a higher production of combustion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the muffler. In addition, the fuel consumption will rise and the performance will decrease.

Handling petroleum products

Utmost care is required when handling fuels. Fuels may contain substances similar to solvents. Refuel either in a well ventilated area or outdoors. Do not inhale fuel vapors, avoid any contact of fuel or oil with your skin.

If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desiccate.

Various skin diseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil, fuel etc.

If oil, fuel, etc., comes into your eyes, immediately wash them with clear water. If your eyes are still irritated, see a doctor immediately!

Replace the fuel pipe every 200 operating hours or every year regardless of operating frequency. Otherwise fuel leakage may lead to fire.

If you find any leakage during inspection, replace the oil pipe immediately.

Replacing the tank cap

• If there is any flaw or damage on the tank cap, replace it.
• The tank cap wears out in course of time. Replace it every two or three years.

For any maintenance or adjustment not described in this manual, ask your local DOLMAR authorized service center.

Daily checkup and maintenance

To ensure a long service life and to avoid any damage to the equipment, the following servicing operations should be performed at regular intervals.

- Before use;

• Check the machine for loose screws or missing parts. Pay particular attention to the tightness of the cutter blade screws.
• Check for clogging of the cooling air passage and the cylinder fins. Clean them if necessary.
• Clean and check the fuel tank for fuel leakage or foreign object in the tank.

- After use;

• Clean the hedge trimmer externally and inspect for damage.
• Clean the air filter. When working under extremely dusty conditions, clean the filter several times a day.
• Check the blades for damage and make sure they are firmly mounted.

STORAGE
