The brake is a disc brake and is located on the gearbox.
Make sure the brake is adjusted correctly by braking sharply
at full speed on level ground. Use a service workshop to
perform this task.

Maintenance
Replacing 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 Open the engine cover.
2 Loosen the knobs holding the filter cover in place and
remove it.
3 Lift out the air filter cartridge from the fan housing.
4 Replace the air filter cartridge, if clogged with dirt.
CAUTION!
Do not use compressed air to clean the paper filter.
Do not oil the paper filter. They must be fitted dry. Carefully
clean the fan housing so that dirt does not fall down into the
carburettor.
5 Refit the air filter and air filter cover.
