1. Remove bolts (2) at 2 places, then remove grease pump
holder bracket (1).
2. Remove wing bolts (4) of grease can (3) at 3 places, then
remove cover (5) together with the grease pump.
3. Remove follow plate (6) inside the grease can.
4. Fill grease can (3) with fresh grease, place follow plate (6)
on top of the grease surface flatly and press it down with
fingers until grease oozes out from the packing portion in
the middle of the plate.
q
Whenputting follow plate on top of the grease, first fill
the hollow in the center of the follow plate with grease
to enable the operation to be carried out smoothly.
5. Insert the grease pump into the packing portion at the cen-
ter of follow plate (6), set cover (5) on grease can (3), then
tighten 3 wing bolts (4) uniformly to hold in position.
6. After fitting grease pump holder bracket (1) into the head of
the grease pump, install with 2 bolts (2).
q
The pump will operate for a short time and then stop, but the first grease includes air inside the pump, so it is
cloudy white and not suitable for use.
7. Loosen check valve (7), and pump out all the grease which
has air in it from hole (a) at the bottom of check valve (7).
8. After bleeding the air, close check valve (7) securely.
9. After bleeding air from inside the pump, pull lever of the
grease gun to completely discharge grease mixed with air
from inside the hose and grease gun.
q
When filling with grease, be extremely careful not to let
sand or dirt stick to follow plate (6) or the suction por-
tion of the grease pump.
q
If there is ample grease, but the pump does not pump
out any grease, follow plate (6) may not be correctly
set in position, so correctly set it into position again.
The standard grease can contains 18 liters. If a 20-liter
can is used, there will be more grease left.
