TOP AND BOTTOM BEAM AND HYDRAULIC LIFT
CYLINDER REMOVAL / INSTALLATION (Con't).
Use extreme caution when lowering top and bottom beams and placing on the
ground. Ensure that lifting device is secure and all personnel stand clear. Failure
to follow this warning may cause serious injury to personnel or damage to beams
and positioning cylinders.
9. Lower top and bottom beams to the ground and support on wooden blocks or other
cribbing if necessary.
10. Swing lift cylinders forward to rest on suspension frame. This will counteract the
removal of the top and bottom beam.
DO NOT disconnect hydraulic lines and fittings while engine is running or before
hydraulic system pressure has been released. When engine is running, hydraulic
system is under pressure. Dolly set must be fully lowered on to the blocks and
the engine must be shut down before lines and fittings are disconnected. A line
or fitting disconnected under pressure will explode with great force and cause
serious injury or death to personnel.
