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.
Recommended settings:
Bar 13"-15": Position 1
Bar 15"-18": Position 2
Bar 18"-20": Position 3
Cooling system
To keep the working temperature as low as possible the 
machine is equipped with a cooling system.
The cooling system consists of:
1
Air intake on the starter.
2
Air guide plate.
3
Fins on the flywheel.
4
Cooling fins on the cylinder.
5
Cylinder cover (directs cold air over the cylinder).
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.
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.
Heated handles
(346XPG, 353G)
On models with the model code XPG/G both the front 
handle bar and the rear handle are equipped with 
!
WARNING! The engine must not be 
running when making adjustments.
