MAINTENANCE

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.

”Air Injection” centrifugal cleaning

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.

Winter use

Running problems can occur when using the machine in the cold and snowy conditions caused by:

•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.

Temperature 0°C (32°F) or colder:

The cylinder cover is designed so it can be adjusted for running in cold weather, so that preheated air from the cylinder can pass into the carburetor space preventing icing of the air ﬁlter, etc.

Temperature -5°C (23°F) or colder:

For running the machine in cold weather or powder snow, a special cover is available, which is mounted on the starter housing. This reduces the intake of cold air and prevents large amounts of snow from being sucked in.

CAUTION! If the special winterising kit has been ﬁtted or any measures have been taken to increase the temperature these changes must be reversed before the machine is used in normal temperature conditions. Otherwise there is a risk of overheating, resulting in severe damage to the engine.

IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer).
