Gearcase lubrication

CAUTION!

ŶOver-lubricating may cause the gearcase to run slower than normal, and may also cause leakage from excess grease.

ŶDo not remove the conrods from the cutters. Conrod bearings can be lost or damaged if disturbed.

Every 20 hours

Top off gearcase grease level by using a lever-type grease gun to force 1–2 strokes of high quality lithium-based grease through the gearcase grease fitting.

Every 100 hours

(or before long-term storage)

Remove the gearcase cover, and use sol- vent and a soft brush to remove all old grease from the gearcase. To refill, hand- pack the gearcase with approximately 40–50 grams of high quality lithium-based grease (50–70% of capacity). DO NOT OVERFILL!
