With machine level, the distilled water should cover the plates by approximately 6mm.
6. Functional Checks.
a. Move the machine, if necessary, to an unobstructed area to allow for elevation.
b. Pull both Emergency stop Switches to the on position.
c. Refer to ‘setting up’ and deploy the outriggers.
d. From the Ground Controls test each machine function, lift and lower both Booms.
e. With outriggers deployed, under load and top or bottom boom raised
approximately 50mm, it must NOT be possible to operate the outrigger controls for
hydraulic outrigger options.
f. With the top and bottom booms raised approximately 500mm each, the unit
switched off and the two Emergency Lower valves under the control cabinet open,
check:
The emergency lower valves located on the lift cylinders lower the boom when
pulled in a slow and controlled manner and that the boom movement is stopped on
releasing the valve
Remember to close the two ball valves after this check.
To Reset the hydraulic system after checks;
□ Fully extend the Outriggers while still maintaining Level. (check the bubble)
□ Using the ground controls, fully extend both Top and Bottom Booms.
All rams must be fully extended at the same time before returning them to
their transit position.
If the Emergency Lower is used during normal operation, DO NOT use
the machine, Contact your local Snorkel representative.
g. From the cage controls test each machine function, lift and lower both Booms and
slew clockwise and counterclockwise.
h. Return the Booms to the stowed position.
i. Emergency stop switches must operate correctly. Check that each stops the
machine’s controls and that restarting is prevented until all stop switches are
unlatched. See Fig 3
