Oil and Fuel Mixing Instructions

1. Fuel used for this model is a mixture of unleaded fuel and approved 2-stroke oil. When mixing fuel with two-stroke engine oil, use only 90 octane or higher unleaded petrol known to be of good quality. This will help to avoid possible damage to engine fuel lines and other engine parts.

2. When preparing fuel mixture, mix only the amount needed for the job you are to do. Always use fresh fuel/oil mixture for optimum performance of your unit. Stale fuel mixture will lead to difficulty in starting your unit and poor performance. Do not use fuel that has been stored. Two-stroke fuel may separate. Shake fuel container thoroughly before each use.

3. Thoroughly mix the correct ratio of 2-stroke engine oil with unleaded petrol in a separate container.

4. Pour the mixture into the fuel tank of the unit. Be careful not to overfill the tank.
5. Replace the fuel cap.

WARNING! Failure to follow proper fuel mixing instructions may cause damage to the engine. Do not smoke while filling the tank. Never operate this machine without the fuel cap securely in place. Do not mix fuel and oil directly into the engine fuel tank of the unit. Never fill the fuel tank to the very top. Never add fuel to the tank in a closed non-ventilated area. Keep sparks and open flames at a distance from the work area. Be sure to wipe off spilled fuel before attempting to start the engine. Do not attempt to refuel a hot engine.

Engine Adjustments

The idle speed of the engine is adjustable. An idle adjustment screw is on the rear side of the carburettor, you could adjust the idle speed of the engine with a socket spanner through the hole of the engine cover (Fig.18).

Idle adjustment screw

Fig 18

NOTE: Careless adjustments can seriously damage your unit. An authorised service dealer should be the only one to make carburettor adjustments.

Adjusting the Engine Idle Speed

IMPORTANT! The machine pipes and air vent cover must be installed while adjusting the engine idle speed. The Engine idle speed will also be affected if either the air vent cover or machine are blocked, damaged, or incorrectly installed.

If, after checking the fuel and cleaning the air filter, the engine still will not idle, adjust the idle speed screw as follows:

1. Start the engine and let it run at a high idle for a minute to warm up. Refer to Starting.
2. Release the throttle trigger and let the engine idle. If the engine stops, use a small Philips or at blade to turn the idle speed screw in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly (Fig.18).

NOTE: Checking the fuel, cleaning the air filter, and adjusting the idle speed should solve most engine problems. If not and all the following are true:

• The engine will not idle.
• The engine hesitates or stalls on acceleration.

• There is a loss of engine power.

Check the spark plug for proper gap and condition. If problem still occurs, have the carburettor adjusted by an authorised service dealer.
