A. GREASING
AUTOMATIC LUBRICATION --- IF EQUIPPED
The automatic lubrication device uses grease-tank-attached
electric pump (1) to automatically lubricate the greasing
points on the front attachment at intervals. Turn auto
lubrication switch (2) ON, then confirm that auto lubrication
displays (4), (5) display on monitor (3).
Electric pump (1) is set to operate for duration of
approximately 2 minutes at 50 operating minutes intervals.
Electric pump (1) is located in the right front cover.
Electric pump (1) and grease tank (6) are all-in-one designs.
The following points are lubricated by the automatic
lubrication device.
As for the bucket and link pins, use a grease gun to
lubricate them. (Refer to the heading “Greasing” in the
“MAINTENANCE” section.)
Check Grease Quantity/Add Grease
Check Grease Quantity:
1. Park the machine on a firm, level surface.
2. Lower the bucket to the ground.
3. Check remaining grease quantity in grease tank (6)
located in the tool box.
IMPORTANT: Check grease tank (6) and add grease as
needed so that the tank does not become
empty. If the electric pump is operated
with the grease tank empty, air will get into
lubrication lines, resulting in insufficient
lubrication.
