3. If traces of oil are observed, stop the engine, remove the tire from the
chain, adjust the oil pump, clean the oil port and an oil hole in the tire. Run
the motor without the tire with a chain and make sure that the oil supply
system arrives. Only then install the tire with a chain on a chainsaw.
Adjustment of the oil pump
1. Insert a screwdriver into the slot of the stem (1) oil pump.
2. Adjust the flow of oil on the chain according to the sign (2), as marked on
the bottom of the saw.
3. Turn the valve stem (1) anti-clockwise towards "MAX" - oil supply
increased by rotating the stem (1) clockwise towards "MIN" - oil supply
decreases.
Checking the emergency brake circuit
WARNING!
If the oil is not supplied to the circuit for 1 minute, we
recommend to stop the engine. Otherwise, the circuit may be
damaged.
WARNING!
If the conduct of the procedure does not resolve the problem,
contact a service center.
NOTE!
Slot rod oil pump (1) is located on the bottom of the saw.
NOTE!
The quantity of oil fed to an oil pump circuit is dependent on
engine speed the higher the speed, the more oil is supplied to
the circuit and vice versa.
CAUTION!
The chain brake is designed to stop the chain for an instant
impact or "kickback." The chain brake is blocked from lock-
in-hand.
Operate a chainsaw with defective brake circuit is prohibited.
