Needle Bearing Lubrication; Adjustment Of The Oil Pump; Cooling System; Centrifugal Cleaning "Turbo - Jonsered CS2186 Operator's Manual

Needle bearing lubrication

The clutch drum is fitted with one of the following drive
sprockets:
• A Spur sprocket (the chain sprocket is welded on the
drum)
• B Rim sprocket (replaceable)
Both versions have a needle bearing on the drive shaft, which
has to be greased regularly (once a week). CAUTION! Use
only high quality bearing grease or engine oil.

Adjustment of the oil pump

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 set to 1 turn open.
Turning the screw clockwise will reduce the oil flow and
turning the screw anti-clockwise will increase the oil flow.
WARNING! The engine must be stopped
!
when making adjustments.
Recommended settings:
Bar -15": 1 turn from the closed position.
Bar 15" -18": 2 turns from the closed position.
Bar 18" -24": 3 turns from the closed position.
Bar 24" -: 4 turns from the closed position.
These recommendations apply to JONSERED chain oil, for
other chain oils increase the oil flow by one step.
MAINTENANCE

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.

Centrifugal cleaning "Turbo"

Centrifugal cleaning means the following: All air to the
carburetor passes through the starter. Dirt and dust is pushed
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 carburetor
compartment.
