WARNING
The loader arm interlevers are potentially dangerous,
when pivoting about their centre they form a 'scissor'
point with the loader arm. Make sure the interlevers are
securely blocked when working in the loader arm area.

1 Park the machine on firm level ground. Engage the
parking brake and set the transmission to neutral.

pins C. The loader arms must be supported, use a tool
as shown.

DANGER
Hydraulic Pressure
Hydraulic fluid at system pressure can injure you. Before
disconnecting or connecting hydraulic hoses, stop the
engine and operate the controls to release pressure
trapped in the hoses. Make sure the engine cannot be
started while the hoses are open.

3 Switch off the engine and vent residual hydraulic
pressure from the loader end by operating the loader
controls back and forth several times.
Note: If a hose burst protection valve is fitted on the ram, the
system will not vent. Extreme caution must be used when
releasing hydraulic connections - release the connections
one turn and allow the pressure to dissipate.
4 Label and then remove the lift ram hoses A. Plug and
cap all open orifices to prevent loss of fluid and ingress
of dirt.

WARNING
Fine jets of hydraulic fluid at high pressure can
penetrate the skin. Do not use your fingers to check for
hydraulic fluid leaks. Do not put your face close to
suspected leaks. Hold a piece of cardboard close to
suspected leaks and then inspect the cardboard for
signs of hydraulic fluid. If hydraulic fluid penetrates your
skin, get medical help immediately.
