MAINTENANCE
4-1 MAINTENANCE CHECK LIST
Perform scheduled maintenance as outlined below.
Lower machine to ground, turn off tractor, and set
parking brake before doing maintenance inspections
or work. All bolts should be torqued as recommend-
ed in torque chart unless otherwise indicated.
BEFORE EACH USE
1. Inspect hydraulic lines and fittings for wear or
leaks. Repair or replace if needed.
2. Inspect all pivot pins for wear. Make certain car
riage bolts, lockwashers and hex nuts are
installed to retain each pivot pin.
3. Check all bolts for tightness.
4. Perform BEFORE EACH USE lubrication per
paragraph 4-2.
5. During operation, listen for abnormal sounds
which might indicate loose parts or other damage.
AFTER EACH USE
1. Clean all debris from machine, especially cylinder
rods and affixed safety decals. Replace any
missing or illegible decals.
2. Inspect loader for worn or damaged components.
Repair or replace before next use. Any replace-
ment components installed during repair shall
include the components’ current safety decals
specified by the manufacturer to be affixed to the
component.
3. Store loader in a dry place.
To keep mounting kit hardware from loosening dur-
ing operation, periodically check that all loader
mounting kit hardware is torqued to specifications
noted in torque chart, Page 36. To aid in mounting
and dismounting loader, apply a small amount of
grease to areas shown in Figure 4-1.
THE LOADER CAN FALL FROM
HYDRAULIC SYSTEM FAILURE. TO
AVOID SERIOUS INJURY OR DEATH,
SECURELY SUPPORT LOADER BEFORE
WORKING UNDERNEATH.
BEFORE EACH USE
1. Boom Pivot Pins - Apply multi-purpose grease to
each fitting (1 fitting each side)
2. Boom Cylinders - Apply multi-purpose grease to
each fitting (2 fittings each cylinder)
3. Bucket Cylinders - Apply multi-purpose grease to
each fitting (2 fittings each cylinder)
4. Bucket Pivot Pin - Apply multi-purpose grease

USE A PIECE OF CARDBOARD OR
WOOD RATHER THAN HANDS AND
WEAR EYE PROTECTION WHEN
SEARCHING FOR HYDRAULIC LEAKS.
ESCAPING HYDRAULIC OIL UNDER
