MAINTENANCE
English – 37
should be replaced after about a month in operation or
earlier if necessary.
Note! Always use the recommended spark plug type! Use of
the wrong spark plug can damage the piston/cylinder. Check
that the spark plug is fitted with a suppressor.
Lubricating the bar tip sprocket
Lubricate the bar tip sprocket each time you refuel. Use the
special grease gun and a good quality bearing grease.
Needle bearing lubrication
The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly (once a
week).
When lubricating, remove the clutch cover by loosening the
two bar n
uts. Lay the saw on its side with the clutch drum
upwards.
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
con
v
erter 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.
!
WARNING! The engine must be stopped
when making adjustments.
