Maintenance Checking and adjusting the choke wire If the engine is producing black smoke or is difficult to start then the choke wire (upper wire) may be incorrectly adjusted. If doubts arise, contact your service representative. If it is necessary to adjust the choke, proceed as follows: Replacing the air filter WARNING! The exhaust system is hot. Let it ! cool before starting to replace the air filter. If the engine seems to lack power or does not run smoothly this may be because the air filter is clogged. It is therefore important to replace the air filter at regular intervals (see Maintenance/Maintenance Schedule for the correct service interval). Replace the air filter as follows: 1 Loosen the knobs holding the filter cover in place and remove it. 1 Release the clamping screw that secures the wire casing and set the choke control to maximum choke. 2 Check that the throttle wire is attached to the upper lever, see diagram. 3 Pull the choke wire casing to the far right and tighten the clamping screw. Replacement of fuel filter Replace the fuel filter every 100 running hours (once per season) or more frequently if it is clogged. 2 Loosen the hose clip that holds the filter cartridge. 3 Remove the filter cartridge from the filter housing. Replace the filter as follows: 1 Open the engine cover. 2 Move the hose clips away from the filter. Use a pair of flat pliers. 3 Pull off the filter from the hose ends. 4 Press the new filter into the ends of the hoses. If necessary apply liquid detergent to the ends of the filter to facilitate connection. 5 Push the hose clips back on the filter and tighten. Checking the fuel pump's air filter Check regularly that the fuel pump's air filter is free from dirt. The filter can when necessary be cleaned with a brush. IMPORTANT INFORMATION Never run the engine without the air filter fitted. The filters must not be oiled. They must be fitted dry. 4 Remove the foam rubber prefilter which is placed around the filter cartridge and clean using a mild detergent. 5 Dry the pre-filter properly. 6 Clean the filter by knocking it with care against a hard surface. Do not use compressed air to clean the filter. Replace the air filter if it is still dirty. Always replace the paper filter every 200 hours. 7 Refit the pre-filter on the paper filter. 24 - English
