Failure to perform the routine maintenance
procedures outlined below may cause your
loader to operate improperly, such operation
could lead to bodily injury. Your loader requires
a few minutes of maintenance before each
use. For your own safety, follow the procedures
suggested below.
1.
After the first 10 hours of loader
operation replace the hydraulic oil filter
on the tractor. Thereafter maintain tractor
hydraulic system as per maintenance
schedule – refer tractor manual for
procedures.
2.
Check hydraulic oil level in tractor and top
up if necessary. Ensure loader is lowered
to ground and bucket fully retracted (all
cylinders in retracted position). Refer
tractor manual for further procedure.
3.
Check all hardware and hoses to ensure
they are secure.
4.
Check hydraulic hoses, connections,
control valve and cylinders for evidence
of leakage.
5.
Check hoses for cracks and cuts. If a
hose is defective replace it immediately.
6.
Check for any hoses that may be rubbing
against sharp surfaces. Re-route any
such hoses immediately.
7.
Lubricate all grease nipples and loader
pivot points daily (10 hours). Refer to
tractor operator’s manual for lubricant
recommendations.
Tractor front tyres should be maintained at
maximum recommended inflation to maintain
normal tyre profile with added weight of loader /
material. Rear tyres must be kept within inflation
pressure range. Unequal rear tyre inflation can
result in bucket not being level to the ground.
