HYDRAULIC RESERVOIR MAINTENANCE
The supply source for the hydraulic system, the oil
reservoir, is located behind the cab. A sight gauge for
checking oil level is located on the reservoir inside the
shrouding.
Check oil level in reservoir before each period of
operation, or daily. If, at any time, you find the level is
low, check the loader for leaks around tubes, hoses,
fittings, and couplings. DO NOT RUN MACHINE WITH
LOW HYDRAULIC OIL!
CAUTION
When maintaining the hydraulic system,
keep all parts clean and remove all dirt
from the area before you begin disassembly.
Use caps and plugs to keep dirt out of
tubelines and openings.
HYDRAULIC OIL CHANGING
PROCEDURE
This procedure should be used once during the breaking in
period of a new loader (after one month, or 100 hours of
operation) and then every six months, or 1000 hours.
Throughout the oil changing procedure remember that
cleanliness is absolutely necessary. Hands, tools,
funnels, oil filling equipment, the oil filler opening, and,
above all, the hydraulic oil itself must be kept absolutely
clean. Dirt in the hydraulic system can cause serious
damage to pumps, valves, and cylinders.
DRAINING THE RESERVOIR
1.
First, be sure boom is lowered to the ground and
secure.
2.
Remove the reservoir drain plug to drain the oil.
CLEANING THE RESERVOIR
1.
Clean the area around the access cover and then
remove the cover.
2.
Remove all dirt and sediment from inside the reservoir
and from filler strainer
3.
After everything in and around the reservoir is
completely clean, replace the drain plug and access
cover.
FILLING THE RESERVOIR
1.
With the drain plug in place and tightened, refill the
tank with the recommended oil through the oil filler
cap/strainer.
2.
With all the control valves in neutral, start the engine,
running it slowly until the new oil circulates throughout
the system and the pump quiets down.
3.
Add more oil until proper level is shown on sight
gauge.
This will work the air out of the system and prevent
cavitation, which is caused by air bubbles
in the oil as it passes through a pump.
4.
Check the oil level again after the loader has been
operating for an hour or two. Add oil as needed.
