Hose Replacement
1. Replace one hose at a time to avoid the risk of wrong connections.
2. When the hose is screwed to an additional fitting or union, use a second spanner on the union to avoid
breaking both seals.
3. Do not use jointing compound on the threads.
4. 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.
Hose Warranty
Warranty is limited to replacement of hoses which have failed due to faulty materials of manufacture. Warranty
will not be considered on hoses that have suffered damage by abrasion, cuts or being pinched or trapped while
in work. Neither will a claim be considered where a hose end has been damaged by a blow or where the
threads or unions have been damaged by overtightening.
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.
