MAINTENANCE
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. The 90 degree elbows at the head
bracket must point directly across the pivot and the hoses must have no slack at this point.
Two hoses clips are provided at either end of the large bore suction and return hoses. These should be
positioned so that their worm drive barrels are opposed at 180 degrees to reduce the possibility of air entering
the system. A stop tap is provided to enable the suction hose to be changed without draining the tank.
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.
P.T.O. GEARBOX
The gearbox is rigidly bolted on to the main frame and has a filler plug. Oil level is correct when level with the
lip of the filler plug aperture. The gearbox oil should be changed every two years or a 1000 hour intervals;
whichever occurs first. The capacity of the gearbox is.25 liters (1/2 pints) of SAE 30/50 universal oil.
