Lubrication
LUBRICATION
Chain life and cutting capacity depend on optimum lubrication. Therefore, the chain is automatically oiled during
operation via oil outlet.
Filling oil tank:
1. Set chain saw on any suitable surface with oil filler cap facing upward.
2. Clean area around the oil filler cap with cloth unscrew cap.
3. Do not remove filter insert during filling.
4. Add chain saw oil until reservoir is full.
5. Avoid dirt or debris entering oil tank, refit oil filler cap (4) and tighten.
It is important to use only the recommended oil to avoid damage to the chain saw. Never use recycled/old oil. Use
of non approved oil will invalidate the warranty.

Important: the chain saw is not supplied filled with oil. It is essential to fill with oil before use.
Never operate the chain saw without chain oil or at an empty oil tank level, as this will result in
extensive damage to the product.
Important: To allow venting of the oil reservoir, small breather channels are provided between
the oil filler cap and the strainer, to prevent leakage ensure machine is left in a horizontal
position (oil filler cap (4) uppermost) when not in use.
