- Avoid spilling petrol or oil.
Spilled fuel should always be wiped up.
- Handle petrol with care, it is highly inflammable.

Chain lubricant

Proper lubrication of the chain while in operation reduces the friction between the chain and
the guide bar to a minimum and assures a longer life time.
Use only special chain oil of high quality for this purpose.
Do not use any waste or reclaimed oil to avoid various problems with the oil pump.
In case of emergency, it is allowed to use motor oil for a short time.
SAE 30...in summer
SAE 10...in winter or for the cutting of wood with a high resin content
