4.4 Cleaning the air filter.

4.4.1 Dirty air filters reduce engine power, increase fuel  

consumption and make starting more difficult, So if there 

is a notic

e

able loss of engine power carry out the following 

steps.

4.4.1.1 Stop the machine.

4.4.1.2 Undo cover screw (1) clockwise and remove 

the air filter cover (2).

4.5 Carburettor - General Information:

4.5.1 Your carburettor comes from the factory with a standard setting. The setting 

provides optimum fuel-air mixture under most operating conditions.

N.B. We advise that you do not adjust the carburettor. If you suspect the carbure

t

tor 

is mal-adjusted or faulty contact your dealer f

or

 assistance.

4.5.2 The high speed screw alters the engine power output and the maximum off 

road engine speed.

4.5.3 If the setting is too lean, there is a risk of engine damage due to insufficient 

lubrication and overheating.

4.6 Checking the spark plug.

4.6.1 If the engine is down on power, difficult to start or runs poorly at idle speed, 

first check the spark plug.

4.7 Remove the spark cover and HT lead (1), remove plug (2) using supplied box 

spanner.

4.8 Check electrode gap (3) (0.6-0.7mm) and adjust if necessary.

4.9 Rectify the problems which have caused the spark plug (3) to become fouled and 

give unfavourable running conditions.
