WARNING
Figure 4-2: Hydraulic Leak Detection
1. The hydraulic lift system contains cylinders plumbed
together. It is important that the cylinders be
connected in the proper series for the lift system to
operate correctly.
2. The hydraulic system is not filled with oil and should
be purged of air before transporting and field
operations. Carefully hitch the Weatherproofer III to
the tractor and connect the hydraulic lift hoses.
Check to make sure the tractor hydraulic reservoir is
full of the manufacturer’s recommended oil. Slowly
raise the machine. With all cylinders fully extended
remove the 1-1/2 X 16 transport lockouts
(See
Figure 4-3.) Store transport lockouts as shown in
Figure 4-4. Lower and raise the unit to verify that
cylinders are working simultaneously throughout the
stroke. Do not loosen any hoses or fittings. Recheck
tractor reservoir to make sure it is within operating
limits.

Escaping hydraulic fluid can cause serious
personnel injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands (See
Figure 4-2.) Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
