FUEL HANDLING

Chain oil

•The chain lubrication system is automatic and we recommend the use of special oil (chain oil) with good adhesion characteristics.

•In countries where no special chain oil is available, EP90 transmission oil can be used.

•Never use waste oil. This results in damage to the oil pump, the bar and the chain.

•It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature.

•In temperatures below 0° C (32° F) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components.

•Contact your service agent when choosing chain oil.

Fuelling

WARNING! Taking the following precautions,

!will lessen the risk of ﬁre:

Do not smoke or place hot objects near fuel. Always shut off the engine before refuelling.

When refuelling, open the fuel cap slowly so that any excess pressure is released gently.

Tighten the fuel cap carefully after refuelling.

Always move the machine away from the refuelling area before starting.

WARNING! The catalytic converter mufﬂer

!gets very hot during and after use. This also applies during idling. Be aware of the ﬁre hazard, especially when working near ﬂammable substances and/or vapours.

Clean the area around the fuel cap. Clean the fuel and chain oil tanks regularly. The fuel ﬁlter must be replaced at least once a year. Contamination in the tanks causes malfunction. Make sure the fuel is well mixed by shaking the container before refuelling. The capacities of the chain oil tank and fuel tank are carefully matched. You should therefore always ﬁll the chain oil tank and fuel tank at the same time.
