Hydraulic Hoses
•
Carefully check condition of all hoses during routine service paying
particular attention to chafed outer casing. Secure wrap with
waterproof adhesive tape to stop the metal braid from rusting.
•
Daily inspect all hydraulic hoses and fittings to be in good order. Any
damages or leaks must be rectified immediately; this is part of the daily
maintenance and is your responsibility, to unsure a long reliable
working life.
•
Hoses with damaged metal braid should be replaced.
•
When replacing hoses quote number stamped on fitting at one end.
The Spearhead hydraulic system works at very high pressure, when
replacing hoses use only genuine hoses, a burst hose could be very
dangerous.
•
When replacing hoses to avoid twisting fitting, use two spanners to
slacken and tighten.
Warning
Hose is weakened when installed in twisted position. Also, pressure pulses in
twisted hose tend to fatigue wire and loosen fittings.
•
Always check the black protective sleeve is in good order, to replace
sleeve is far cheaper than replacing expensive hoses.
•
Hose warranty is limited to replacement of hoses due to faulty materials
or manufacture Warranty will not be considered on hoses damaged by
chafing, abrasion, cuts or pinching while in work, or to damaged
threads due to over tightening.

All hose connections
are of a “Parker” soft seal type and only need 1/2
a turn more than finger tight to become leak-proof.
