Polemounted pruner attachment
Filling saw chain oil
The machine is supplied without the oil tank of the
polemounted pruner filled with saw chain oil.
Never operate the polemounted pruner without
chain lubrication!
Use without saw chain oil leads to damage to the saw
chain and the guide rail.
The service life and cutting performance of the chain
depends on optimum lubrication. The saw chain has oil
applied to it automatically during operation.
Place the polemounted pruner on a suitable surface.
1. Unscrew the cap (17-1).
2. Fill the oil tank with biodegradable saw chain oil. Use
a funnel for easier filling.
When filling, make sure no dirt gets into the oil tank.
3. Screw the cap closed again.
4. Never fill with recycled oil or used oil. The warranty
will be invalidated if an oil not authorised for saw
chains is used
