Service Schedule
1�
Check the hydraulic oil daily. Add oil if required. Periodically inspect the hoses and fittings for leaks.
Change hydraulic oil filter after first week (or not more than 50 hours) of operation on a unit.
2�
After first filter change, replace filter when indicator reaches Danger Zone.
3�
The reservoir should be drained through drain plug (not through suction outlet), flushed, and refilled
annually, or the oil should be changed if it shows any signs of breaking down under continued high-
pressure operation� Discoloration of oil is one sign of breakdown�
Hydraulic Hose
Hose assemblies in operation should be inspected frequently for leakage, kinking, abrasion, corrosion or
other signs of wear or damage� Worn or damaged hose assemblies should be replaced immediately�
Testing should be conducted in approved test stands with adequate guards to protect the
operator� Failure to comply with this requirement could result in death or serious injury�
Clean
Clean assembly by blowing out with clean compressed air� Assemblies may
be rinsed out with mineral spirits if the tube stock is compatible with oil,
otherwise hot water at 150°F (65�55° C) maximum may be used�
Inspect
Examine hose assembly internally for cut or bulged tube, obstructions, and
cleanliness. For segment style fittings, be sure that the hose butts up against
the nipple shoulder; band and retaining ring are properly set and tight, and
segments are properly spaced� Check for proper gap between nut and
socket or hex and socket� Nuts should swivel freely� Check the layline of the
hose to be sure the assembly is not twisted� Cap the ends of the hose with
plastic covers to keep clean�
Test
The hose assembly should be hydrostatically tested at twice the
recommended working pressure of the hose�
Test pressure should be held for not more than one minute and not less than
30 seconds� When test pressure is reached, visually inspect hose assembly
for: 1. Any leaks or signs of weakness. 2. Any movement of the hose fitting
in relation to the hose� Any of these defects are cause for rejection�
Storage and Handling
Hose should be stored in a dark, dry atmosphere away from electrical equipment, and the temperature
should not exceed 90° F (32�22° C)�
