Cleaning Foam Filter Air Cleaner
1. Wash the element in a solution of water and liquid soap. Squeeze dry in a clean cloth.
2. Saturate element in engine oil and squeeze in a clean cloth to remove excess oil.
3. Wipe dirt from the air cleaner body. Be careful to prevent dirt from entering the air duct
that leads to the carburettor.
4. Fit element in air cleaner and replace cover making sure it is properly sealed.
Cleaning Paper Filter Air Cleaner
1. Tap the filter several times on a hard surface to remove dirt, or blow compressed air (not
exceeding 30 psi [207kPa, 2.1kg/cm
²
]) through the filter from the clean side that faces the
engine. Never try to brush off dirt. Brushing will force dirt into the fibres.
2. Tap the filter outer several times on a hard surface to remove dirt. If the filter outer is very
dirty, replace the filter outer.
3. Wipe dirt from the air cleaner body. Be careful to prevent dirt from entering the air duct that
leads to the carburettor.
CAUTION:
Operating the engine without an air filter, or with a damaged air filter, will allow
dirt to enter the engine, causing rapid engine wear. This type of damage is not covered by the
Warranty.
6.5 SPARK PLUG SERVICE
Use Genuine Rover spark plugs.
CAUTION:
An incorrect spark plug can cause engine damage.
1. Disconnect the spark plug cap, and remove any dirt from
around the spark plug area.
2. Remove the spark plug with a spark plug wrench.
3. Inspect the spark plug. Replace it if the electrodes are worn, or if the insulator is cracked or
chipped.
4. Measure the spark plug electrode gap with a suitable gauge.
The gap should be 0.70 - 0.80 mm. Correct the gap, if necessary, by carefully
bending the side electrode.
5. Install the spark plug carefully, by hand, to avoid cross-threading.
6. After the spark plug seats, tighten with a spark plug wrench to compress the washer.
If reinstalling the used spark plug, tighten 1/8 - 1/4 turn after the spark plug seats.
If installing a new spark plug, tighten 1/2 turn after the spark plug seats.
CAUTION:
A loose spark plug can overheat and damage the engine.
Over tightening the spark plug can damage the threads in the cylinder head.
7. Attach the spark plug cap.
0.70-0.80 mm
