Special Maintenance Tasks
The following items should be performed by a trained maintenance expert.
1.
Replacement of hydraulic hoses.
2.
Replacement or rebuilding air and hydraulic cylinders as required.
3.
Replacement or rebuilding pumps / motors as required.
4.
Checking of hydraulic cylinder rod and rod end (threads) for deformation or damage.
NOTE:
Relocating or changing components may cause problems. Each component in the
system must be compatible; an undersized or restricted line will cause a drop in pressure. All
valve, pump, and hose connections should be sealed and/or capped until just prior to use. Air
hoses can be used to clean fittings and other components. However, the air supply must be
filtered and dry to prevent contamination. Most important - cleanliness - contamination is the
most frequent cause of malfunction or failure of hydraulic equipment.
Chain Maintenance
NOTE:
The chains/hooks supplied with Chief equipment are high quality, high strength
chains/hooks. If replacement is required, purchase only original Chief product from an
authorized Chief Automotive representative.
Before each use, chains must be inspected for wear, nicks, gouges, stretched and bent links.
If found, replace chain.
Before each use, chain hooks must be inspected for twisted and stretched openings. If found,
replace chain.

DO NOT overfill pump reservoirs.
The hydraulic electric pump for the Kahuna lift system contains 2.9 gallons (11 liters) of
hydraulic oil. When refilling or adding oil, fill to within 1” (25 mm) of fill port using SUS 215
viscosity @ 100°F (38°C) 10W hydraulic oil.
The hydraulic pneumatic foot pump contains 1.7 liters of hydraulic oil. When refilling or adding
oil, fill to within 1” (25 mm) of fill port using SUS 215 viscosity @ 100°F (38°C) 10W hydraulic
