MAINTENANCE SCHEDULE

AFTER THE FIRST 25 HOURS RUNNING
• Change gearbox lubricant (See separate gearbox
manual).
• Check that all external nuts, bolts and fastenings are
tight. Do NOT over tighten. Special attention should
be paid to the flexible mount lock nuts, these should
be checked for tightness, starting with lower nut first
in each case. If the lower nuts are found to be very
loose, then the alignment of the shaft to the gearbox
half coupling should be re-checked. Poor alignment
due to loose flexible mount nuts will cause excessive
vibration and knocking.

gearbox and speed control levers. Grease both fittings
