is performed.
3. Do not disconnect hydraulic hoses while there is
still pressure in those components.
4. Before disconnecting hydraulic components,
shut off the engine, release any air pressure on
the hydraulic reservoir, and move control levers
repeatedly through their operating positions to
relieve all pressures.
5. Keep the Cable Hoist clean and free from
grease build-up, oil and dirt to prevent slippery
conditions.
6. Perform all safety and maintenance checks
before each period of use.
7. Replace parts with Stellar Industries, Inc.

ponents found to be inadequate.
Maintenance Procedures
1. Position the Cable Hoist where it will be out of
the way of other operations or vehicles in the
area.
2. Place all controls in the off position and secure
operating features from inadvertent motion.
3. Relieve hydraulic oil pressure from all hydraulic
circuits before loosening or removing hydraulic
components.
4. Label or tag parts when disassembling.
Periodic Inspection
Periodic Inspection should occur while the Cable
Hoist is in use. For the duration of the usage,
inspect the Cable Hoist for all of the following:
1. Loose bolts and fasteners.
2. All pins, bushings, shafts, and gears for wear,
cracks, or distortion to include all pivot points,
and bushings.
3. Hydraulic systems for proper operating pressure.
4. Main frame mount bolts.
5. Cylinders for:
A. Damaged rods.
B. Dented barrels.
C. Drift from oil leaking internally.
D. Leaks at rod seals or holding valves.
6. PTO and hydraulic pump(s) for leaks.
7. Hydraulic hose and tubing for evidence of dam-
age such as blistering, crushing, or abrasion.
8. Presence of this owner’s manual.
Daily Inspection
Daily Inspection should occur each day before the
Cable Hoist is put into use. Each day, inspect the
Cable Hoist for all of the following:
1. Hydraulic oil level.
2. Loose parts or damage to structures or weld.
3. Cylinder movement due to leakage.
4. Hoses for evidence of oil leaks.
5. Controls for malfunction or adjustment.
6. Parking brake operation.
7. All securing hardware such as cotter pins, snap
rings, hairpins, and pin keepers for proper installa-
tion.
8. All safety covers for proper installation.
9. Cylinder holding valves for proper operation.
10. Equipment for missing, illegible, or defaced
operating decals and safety signs.
11. Inspect the wire rope for fraying or other wear.
Monthly Inspection
Monthly Inspection should occur at the beginning
of every work month. Each month, inspect the
Cable Hoist for all of the following:
1. Frame bolt tightness - turn barrel nuts and mount-
ing bolts during the first month of operation on
new machines and then quarterly thereafter.
2. Cylinders and valves for leaks.
3. Lubrication.
4. Structural weldments for bends, cracks, or breaks.
5. All pins and keepers for proper installation.
6. All control, safety, and capacity placards for

ful in finding and fixing problems:
1. Determine the problem.
2. List and record possible causes.
3. Devise checks.
4. Conduct checks in a logical order to determine
the cause.
5. Consider the remaining service life of compo-
nents against the cost of parts and labor neces-
sary to replace them.
6. Make the necessary repair.
7. Recheck to ensure that nothing has been over-
looked.
8. Functionally test the new part in its system.
