MAINTENANCE
Replacing Shaft Seals
1.The double shaft seal assembly must be assembled with the 7 MM. wide single lip seal fitted first with the 1 MM. thick lip support washer on top.
2.The back of the double lip seal should be filled with a light grease before fitting with the wiper lip outermost.
3.The seal kit, Part No.
HYDRAULIC HOSES
The condition of all hoses should be carefully checked during routine service of the machine. Hoses that have been chafed 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
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 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.
5.Before changing hoses, study the installation. These should be positioned so that their worm drive barrels are opposed at 180 degrees to reduce the possibility of air entering the system.
Hose Warranty
Warranty is limited to replacement of hoses which have failed due to faulty materials or manufacture. Warranty will not be considered on hoses that have suffered damage by abrasions, 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.
