MAINTENANCE
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.
•Preheat the intake air to the carburetor by using the heat from the cylinder.
Temperature 5°C (41°F) or colder:
The air filter holder is prepared so it can be changed for use in the cold. Remove the air filter cover and air filter. Turn the winter cover anticlockwise using a screwdriver so that the preheated air from the engine can pass inside the carburettor compartment and prevent, for example, the air filter from icing up (see figure).
For temperatures below 5°C (41°F) and/or in snow conditions there is also:
•a special cover for the starter housing
These reduce the cooling air and prevent large amounts of snow from being sucked into the engine.
IMPORTANT! The machine MUST be returned to its standard design at temperatures warmer than 5°C (41°F). Otherwise there is a risk of overheating resulting in serious engine damage.
IMPORTANT! Use only JONSERED replacement parts. Use of other brands of replacement parts can cause damage to your unit or injury to the operator or others.Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not specifically recommended by JONSERED.
