GENERAL MAINTENANCE
Top up engine oil daily and change regularly using the correct grade of oil in
accordance with the engine manufacturers instructions. If the machine is working
continuously, check the oil level and top up twice daily.
Clean the air filter element regularly. In very dry, dusty conditions, this should be
done daily.
Lightly oil the wheel spindles and wheel arm spindles monthly.
Check tightness of all nuts and bolts monthly.

ENGINE
Removal
Unfasten screws (19) and remove the guard (20) and the vee belt (16). Remove the
engine mounting bolts (21) and nuts and lift off engine. For engine service, refer to
the manufacturer’s instructions.
Replacement
To refit engine, reverse removal instructions. Set engine speed to 3300 r.p.m.
7.
VEE BELT ADJUSTMENT
Unfasten screws (19), remove the guard and check belt tension. It is important to
note that belt tension in this application is much less than is generally accepted as
normal. Too high a belt tension may lead to engine damage due to excessive
transmission of vibration from the power pack through the vee belt.
To adjust belt tension, loosen the engine mounting nuts and screws (21) and move
the engine backwards towards the handle until the front of the engine mounting plate
moves downwards slightly. Adjust the engine position to allow the mounting plate to
just return to normal level position and tighten the engine mounting nuts and screws
after making a final check that the clutch pulley is in line with the bottom pulley.
