VALVE SETTINGS

All valves have been pre-set at the factory to ensure that the lift functions properly. Any readjustment of these
valves by anyone other than a factory-authorized representative will void the warranty and possibly cause damage
to the lift or structure of the boat.

HYDRAULIC FLUID

General Hydraulic Solutions recommends using an ISO 46 (aw) hydraulic fluid. This fluid is compatible with all
valves and pumps used in the power unit assembly. The reservoir in the power unit should be checked for proper
level every 200 cycles or every 6 months. The level should be approx. 1" from the top when the unit is in the "UP"
position. If the level of the fluid falls below a certain point in the reservoir, the pump has the potential to fail and /
or introduce air into the system. This will affect the operation of the unit drastically. If air is introduced into the
system whether from a broken hose or the fluid level being too low, simply refill the reservoir with fluid, make
sure there are no leaks on the inside or outside of the boat, then run the unit up and down 1 time only. Recheck
the fluid level then let the unit sit for 2 hrs or longer to allow all air bubbles to escape from the fluid in the
reservoir. Run the unit again 1 time and repeat the process outlined above. This may take several times to clear all
air in the system.

3 GREASE FITTINGS
There are 2 grease fittings positioned on the top of the lift cylinders. (see page 38) These fittings should be
greased once a year with a good moly based grease.

OVERALL APPEARANCE AND SYSTEM CLEANLINESS

The General Hydraulic Solutions lift platform is constructed of 316L stainless steel and 464 naval brass. All parts
that will be below the waterline have either been electro polished or bottom painted. This should give years of
trouble free service. The overall appearance of the system should be inspected once or twice a year during haul
out. All cylinders, both lifting and locking, should be inspected for leaking of seals and general appearance. All
cylinder rods should be checked in the down position for excessive wear. All bushings should be checked for
excessive play. The hydraulic system should be checked once a year also.The hydraulic system should be
checked once a year also. The fluid should be checked for cleanliness. Any fluid that looks milky or other than an
amber like color should be replaced and the system flushed out. All hoses should be checked for fraying or
leakage. All fittings both internally and externally should be checked for leaking or looseness and should be
tightened at this time.
The zinc anodes should be checked periodically (quarterly) and replaced when corrosion is evident. Excessive
degeneration of this anode could lead to premature corrosion problems in the lift. General Hydraulic Solutions
uses a CAMP T-20 anode, Part # HW021 (see Tab Parts List -Page 1). These can be purchased through GHS.
5 HYDRAULIC FILTER
There is a 10-micron hydraulic filter (see page 17-31) built into the manifold in the pump assembly unit. This filter
should be changed once a year to prevent possible contamination of the system. This filter should be changed
during all maintenance or repair of the system. Filters can be purchased through General Hydraulic Solutions.
