Storing tool
Biologically degradable saw chain oil can only be kept
for a limited period. Beyond two years after manufacture,
biological oils begin to acquire an adhesive quality, and
cause damage to the oil pump and components in the
lubricating system.
− Before taking the chain saw out of service for a
longer period, empty the oil tank and fill it with a
small quantity of engine oil (SAE 30).
− Run the chain saw briefly to flush all residue of the
biological oil out of the tank, lubricating system
and saw mechanism.
NOTE:
• When the chain saw is taken out of service, small
quantities of chain oil leaks from it for some time
afterwards. This is normal, and is not a sign of a
fault.
Store the chain saw on a suitable surface.
Before returning the chain saw to service, fill up with
fresh BIOTOP saw chain oil.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers,
always using Makita replacement parts.
