HYDRAULIC HOSES
The condition of all hoses should be carefully checked during routine service of
the machine. Hoses that have been chaffed or damaged on their outer casing
should be securely wrapped with waterproof adhesive tape to stop the metal
braid from rusting. Hoses that have suffered damage to the metal braid should
be changed at the earliest opportunity.
HOSE REPLACEMENT
• Replace one hose at a time to avoid the risk of wrong connections.
• When the hose is screwed to an additional fitting or union, use a second
spanner on the union to avoid breaking both seals.
• Do not use jointing compound on the threads.
• Avoid twisting the hose. Adjust the hose line to ensure freedom from
rubbing or trapping before tightening hose end connections.
Before changing hoses study the installation these are carefully calculated to prevent
hose
damage during operation. Always replace hoses in exactly the same manner. This
is especially important for the flail hoses where they must be crossed, upper to
lower, at the dipper and head pivots.
SAFETY NOTE
Soft Seal hose connections are capable of holding pressure when the nut is only
‘finger tight’. It is therefore recommended that when dismantling, the hose be
manually flexed, to relieve any residual pressure, with the retaining nut slackened
prior to complete disassembly.
