Lubrication of Gears
There is usually sufficient grease to last at least 4 years or
100 hours of domestic use before topping it up. The grease
in the gear case should be filled up according to use by
adding light, free-flowing grease (available from Mantis,
P/N #9985) through screw hole marked “fill” (Picture 4).
Use a suitable filling gun or squeeze grease pack. Remove
screw marked “bleed.” Squeeze in 3-4 pumps of grease,
until it comes out of the bleed hole. Refit fill screw.
NOTE: Do not use light or heavy gear oil as
it might leak out. If gear case shows leakage,
tighten all screws or replace O-ring. Refill casing.
