10.2
Air filter
The air filter should be cleaned regularly removing dust and dirt to avoid:
▪
Carburettor malfunction.
▪
Starting problems.
▪
Reduced engine power.
▪
Unnecessary wear to engine parts.
▪
Abnormal fuel consumption.
Cleaning the air filter:
▪
Dismantle the air filter cover and remove the air filter.
▪
Wash in clean, warm soapy water.
▪
Ensure that the filter is dry before refitting.
▪
An air filter used for a long period of time can never be cleaned completely. Therefore it
is necessary to replace the air filter from time to time with a new filter.
Attention! Do not ever use the unit without its air filter. The filter must be kept
clean. A damaged filter must be replaced with a new one.
10.3
Change/adjustment of the spark plug
Attention! Worn-out spark plugs or too large distance between breaker
contacts decrease the engine performance.
▪
Turn the unit off.
▪
Disconnect the sparkplug cable from the spark plug.
▪
Unscrew counterclockwise the spark plug with a spark plug key. Do not use any other
tool in order to prevent any damage.
▪
Use a control template (available at specialized shops) and check the distance between
the breaker contacts. The distance must be 0.635 mm.
▪
If necessary, correct the distance by carefully bending the ignition arch of the spark plug.
▪
Clean the spark plug with a wire brush.
▪
Insert a cleaned and adjusted spark plug or replace the damaged one by a new one.
▪
Reconnect the spark plug cable.
10.4
Carburettor adjustment
The carburettor was adjusted to optimum performance already during production. If the
carburettor requires readjustment, have it done at a specialized expert repair shop.
