MAINTENANCE
Lubrication involves engine oil dripping into the centre of the clutch drum as it rotates.
Adjustment of the oil pump
(346XP/353)
The oil pump is adjustable. Adjustments are made by turning the screw using a screwdriver or combination spanner. The machine is supplied from the factory with the screw set to position 2. Turning the screw clockwise will reduce the oil flow and turning the screw anti- clockwise will increase the oil flow.

Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.
Note! The cooling system on a chain saw with catalytic converter must be cleaned daily. This is particularly important on chain saws with catalytic converters, because the higher exhaust temperature requires efficient cooling of the engine and the catalytic converter unit.
”Air Injection” centrifugal cleaning
Centrifugal cleaning means the following: All air to the carburettor passes through the starter. Dirt and dust is centrifuged out by the cooling fan.

Cooling system
To keep the working temperature as low as possible the machine is equipped with a cooling system.
The cooling system consists of:
1Air intake on the starter.
2Air guide plate.
3Fins on the flywheel.
4Cooling fins on the cylinder.
IMPORTANT! In order to maintain operation of the centrifugal cleaning system it must be regularly maintained. Clean the air intake to the starter, the fins on the flywheel, the space around the flywheel, inlet pipe and carburettor compartment.
