General
When the machine is stopped for servicing, inspection, or to change an accessory, shut off the
engine, push down the clutch lever, disconnect the spark plug wire from the spark plug and
make sure that all moving parts have come to a complete stop. Due to the magneto starting
system, the engine may start when the cutting means is moved unless the ignition switch is off
and the spark plug wire is removed from the spark plug. Never rely on the clutch to positively
disengage the drive mechanism.
Allow the machine to cool before inspection, adjustments etc.
oil check and replacement
The engine oil level should be checked regularly, every 4 hours of operation. For oil replacement,
see the engine manual.
air filter cleaning
Check the condition of the air cleaner regularly, in dusty conditions every 4 hours. See engine
book for cleaning details.
Drive belt adjustment / replacement
The drive belt may become loose after an initial settling in period, after very heavy loads have
been applied or after an extended period of use. You can tell if the belt is slipping by a reduction
in material feed rate or by the belt smoking. when ‘slipping’ is suspected, do not continue to
use the machine. Tighten the belt as follows:
• Switch off the engine and remove the spark plug lead from the spark plug.
• Using a 13mm spanner, remove the plastic belt guard.
• Observe the condition of the belt. If it is severely frayed or has a burnt section, it will need
to be replaced.
