MAINTENANCE
Cooling system
To obtain the lowest possible running temperature the saw is equipped with a cooling system.The cooling system consists of:
1. | Air intake on the starter | 5 | |
| unit. |
| |
2. | Air guide plate. | 4 | |
| |||
3. | Fan blades on the | 3 | |
| |||
| flywheel. |
| |
4. | Cooling fins on the |
| |
| cylinder. |
| |
5. | Cylinder cowling | 2 | |
1 | |||
| (supplies 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 saw overheating which causes damage to piston and cylinder.
Centrifugal cleaning ”Air Injection”
Centrifugal cleaning means the following:
All air to the carburetor is carried through the starter. Dirt and dust is centrifuged away by the cooling fan.
IMPORTANT! In order to keep the function of the centrifugal cleaning, a continous maintenance and care must be made.
•Clean the air intake to the starter, the fan wings of the flywheel, the space around
the flywheel, inlet pipe and carburetor space.
Heated handles
On the model XPG both the front handle and the rear handle are equipped with electrical heating coils. These are supplied with electricity from a
Winter use
During winter time, powder snow and cold weather can cause running problems, such as:
•Too low engine temperature.
•Icing on the air filter and carburetor.
Therefore some special measures are required:
•Partly reduce the air inlet of the starter and by doing that increase the engine temperature.
•Preheat the intake air to the carburetor by removing the special plug between the cylinder and the carburetor space.
Mounting of winter kit
• Brake away and discard the intermediate wall.
• Cut out the hole by using a knife according to the illustration.
• Mount the winter plug.
Temperature 0oC (32oF) or colder
Move the plug from position |

1 to position 2 so that the | 1 | |||||
preheated air from the | ||||||
| ||||||
cylinder can pass into the |

carburetor space and | 2 | |||||
prevent icing on the airfilter. | ||||||
NOTE! When the plug is |

for the ”Air injection” the air |

For running the saw in cold weather or powder snow, a
special cover is available, which is mounted on the
starter housing. This reduces the air flow and prevents large amounts of snow from being sucked in.
IMPORTANT! If a special winter kit is assembled or measures are taken to increase the engine temperature, a readjustment to normal setting has to be done when the saw is used under normal conditions. Otherwise, there is a risk of overheating, which can cause severe engine damage.
IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer.
