From 1998
EC machines, which are “CE”, marked are fitted with a hose burst valve to protect the
operator in the event of a hose failing.
The valve are pre-set on leaving the factory fitted to a machine but occasionally
require adjusting as they wear in service. To adjust, ensure the hopper is lowered
and any residual hydraulic pressure has been dissipated by operating the control
lever a number of times with the engine/motor stopped. Remove the valve from the
ram noting which way round it was installed, the body is marked. Unscrew the inner
baffle assembly, noting which way it was installed and adjust the baffles by holding
the nut and turning the capscrew with a hexagon key until the gap between the
baffles measures 0.889mm.
The valve should then be re-assembled and screwed onto the ram, ensuring the
valve is the correct way round. Fit the hydraulic adapter and bonded seal coating the
threads with hydraulic sealer. See Service Bulletin in SB100 for further details on the
valve.
Note, position the assembled ram into the mainframe so that the fitting/hose burst
valve face the L/H side (hopper cradle) of the mainframe.
New valves supplied or received as a spares item should be dismantled before fitting
and the inner baffles adjusted by holding the nut and turning the capscrew with an
hexagon key until the gap between the baffles measures 0.889mm.
It is quite common for machines fitted with hose burst valves to ‘lock out’ in service
with the result that a raised hopper will not lower. Operating the control lever in a
‘violent’ manner to shake material free is the major cause of ‘lock outs.’ To release a
‘locked out’ hose burst valve slowly and gently operate the control lever to raise the
hopper, this will blow off the ‘locked out’ valve allowing the hopper to be gently
lowered approximately 150mm following which the hopper can be used as normal.
Hydraulic Tank
The hydraulic tank is mounted below the cover on the side of the engine housing. To
gain access to the suction strainer or clean the filler breather it will be necessary to
remove the cover and the open up the tank via the removable circular cover located
on top of the tank.
The suction strainer is screwed onto the suction fitting inside the tank and should be
removed and cleaned in accordance with the service schedules. A drain plug is
provided below the tank assisting oil changes, and the tank can be quickly removed
should it be necessary to steam or pressure clean out.
Hopper Removal
The hopper is retained to the cradle by means of a number of ‘coach bolts’. To
remove fully lower the hopper, attach suitable lifting equipment to the hopper lifting
points, remove the coach bolts and lift the hopper clear.
