Adjustment Of The Oil Pump; Cooling System; Centrifugal Cleaning "Turbo; Heated Handles - Husqvarna CS 2186 Operator's Manual

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 not be running
!
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.

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.

MAINTENANCE

Centrifugal cleaning "Turbo"

Centrifugal cleaning means the following: All air to the
carburetor 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 carburetor
compartment.

Heated handles

(CS 2186W)
On models with the model code W, both the front handle bar
and the rear handle are equipped with electrical heating coils.
These are supplied with electricity from a generator built into
the chain saw.
When the red mark on the switch is visible, the heating is on.

Electrical carburetor heating

(CS 2186WH)
If this chain saw has the model code WH/CWH then it is
equipped with an electrically heated carburettor. The
electrical heating prevents icing in the carburettor. A
thermostat regulates heating so that the carburettor always
has the correct working temperature.

Winter use

During cold weather and under powder snow conditions,
operating problems can arise due to:
• Too low engine temperature.
• Icing of the air filter and carburetor.
Special measures are therefore often required:
• Partly mask the air inlet on the starter to increase the
working temperature of the engine.
