2.Pull the throttle wire’s outer casing to the far right and check that the choke is fully activated.

3.Tighten the clamping screw.

4. Pull the throttle control back to the full throttle position and check that the choke is no longer activated.

Replacement of the fuel filter

Replace the pipe fitted fuel filter every 100 running hours (once per season) or more frequently if it is clogged.

Replace the filter as follows:

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 in the new filter on the hose ends. If necessary soap solution can be applied on the filter ends to simplify fitting.
