Makita UC3041A Manuel D'instruction page 18

CAUTION:
A worn sprocket damages a new saw chain. Have
•
the sprocket replaced in this case.
Always fit a new locking ring when replacing the sprocket.
Maintaining the chain and run-down brakes
The braking systems are very important safety features.
Like any other component of the chain saw, they are
subject to a certain degree of wear. They must be
inspected regularly by MAKITA authorized or factory
service centers. This measure is for your own safety.
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.
Malfunction status
The chain saw does not
start.
Chain does not run.
Insufficient performance.
No oil on the chain.
Chain does not stop
even the chain brake is
engaged.
The tool vibrates
abnormally.

Possible cause
No power supply.
Cable defective.
Tool malfunction.
Chain brake is engaged.
Carbon brush worn down.
Oil tank is empty.
Oil guide groove is dirty.
Oil pump adjusting screw
incorrectly adjusted.
Brake band worn down.
Loose guide bar or saw
chain.
Tool malfunction.
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,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized or Factory Service Centers, always
using Makita replacement parts.
