MAINTENANCE
Air filter
The air filter (A) must be cleaned regularly to remove dust and dirt. This will prevent:
• | Carburetor malfunctions |
|
• | Starting problems |
|
• | Reduced performance | B A |
• | Unnecessary wear on engine parts |
•Abnormal fuel consumption
•Elevated content of harmful exhaust fumes
Clean the filter after 25 hours of operation or more often if the air is exceptionally dusty in the work area.
To clean the air filter
Dismantle the air filter cover (B) and remove the filter medium. Wash it clean in a solution of soap and warm water. Make sure that the filter is dry before reassembling.
An air filter, which has been used for some time, can- not be cleaned completely. Therefore,the filter must be replaced by a new one at regular intervals. A faulty filter must always be replaced.
Spark plug
The condition of the spark plug is influenced by:
•An incorrectly adjusted carburetor.
•Wrong fuel mixture (too much oil in the gasoline).
•Poor quality gasoline and/or oil.
•A dirty air filter.
These factors cause deposits on the spark plug electrodes, which may result in malfunction and difficulty starting the blower.
If the engine is low on power, difficult to start or runs poorly at idling speed, always check the spark plug first.
The spark plug is accessible under the cylinder shrouding, which can be removed by unscrewing four screws.
If the spark plug is clogged, clean it and check the electrode gap.
NOTE! Always use the recommended type of spark plug! See under ”Technical data”. An incorrect spark plug can severely damage the piston/cylinder.
