Lubrication & Maintenance
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° C).
Conveyor Chain
Stay out of the spreader� If it’s necessary to enter the hopper, return to the shop, empty body,
turn off all power, set vehicle brakes, lock engine starting switch and remove keys before
entering� Tag all controls to prohibit operation� Tags should be placed, and later removed,
only by person working in the body� Failure to comply with this requirement could result in
death or serious injury�
Hose down unit and remove any material build-up on sprockets and under chain�
The conveyor will move away from the bottom panel if material accumulates under the
conveyor or on the sprockets� The more material that accumulates, the closer the chain will
come to the chain shields� If the conveyor should catch a chain shield, it could permanently
damage the conveyor, the chain shields or the unit� Do not remove material while conveyor or
spinner is running!
