OPERATION AND MAINTENANCE
Hydraulic Fold System
1. The Weatherproofer I is equipped with a hydraulic
fold system to raise and lower the wing frames for
narrow transport.
2. Be sure the system is fully charged with hydraulic oil
before attempting to fold/unfold the unit. Air in the
system can allow uncontrolled dropping of the wing
frames causing serious personal injury or machine
damage. The system needs to be charged with oil
initially and any time the system has been opened for
repair such as cylinder, hose, or fitting
replacement/repair.
3. To charge the system, carefully hitch the
Weatherproofer I to the tractor. Unpin the end(s) of
the fold cylinders, and position them so they can
extend and retract without contacting any frames or
other parts. Check the tractor hydraulic fluid level to
make sure it is full of the manufacturer’s
recommended hydraulic fluid. Connect the cylinder
hoses to the tractor and fully extend and retract the
cylinders several times. The cylinder rod travel
should be smooth and positive when all air has been
purged from the system. Due to large amounts of
hydraulic oil required, recheck the tractor fluid level to
make sure it is within proper operating limits.
4. The hydraulic fold system is equipped with restrictors
in the rod end of cylinders to prevent uncontrolled
falling of wing frames when unfolding. Removal or
improper assembly of these restrictors can cause the
machine to fold improperly and result in serious
machine damage.

WARNING
Escaping hydraulic fluid can cause serious
personal 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.
