Lubricating The Bar Tip Sprocket; Needle Bearing Lubrication; Adjustment Of The Oil Pump; Cooling System - Husqvarna 61 Operator's Manual

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 nuts. Lay the saw on its side with the clutch
drum upwards.
Lubrication involves grease being squirted into the centre
of the crankshaft using a grease gun.

Adjustment of the oil pump

The oil pump can be adjusted to give four different oil flow
rates. To adjust the flow rate, first remove the chain, bar,
clutch cover, centrifugal clutch, and the clutch drum.
Using a screwdriver, adjust the oil flow rate by turning the
adjuster screw one way or the other. The projection on the

screw should point towards the chosen setting. The
diagram shows the setting for flow rate 2.
Recommended settings:
Bar 13"-15":
Bar 18"-:

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.
