INSTRUCTIONS FOR THE SAFE USE OF THE
GHS HYDRAULIC PLATFORM LIFT
General Hydraulic Solutions (GHS) manufactures a line of hydraulic swim platform lift systems for
the marine industry. All lift systems are designed to safely and efficiently lift and support a static
load of 700 pounds on the swim platform of a variety of marine vessels. The systems are
designed with a safety factor of 5, which means that the system will support a static load of 4500
pounds without failure when the load is placed midway between the transom and the aft end of
the swim platform (30” aft of the transom). Independent testing has confirmed that the unit will
withstand a 4500-pound static load without failure. As the load increased or moves aft, the
margin of safety decreases and the ability of the lift to perform is degraded. Also, as the load is
increased or moves aft, the ability of the transom to resist the increased moment becomes
another safety concern. GHS recommends that the swim platform load be limited to 700 pounds
and that the load is centered midway fore and aft on the swim platform. GHS offers an optional
set of chocks that is specifically designed to support a PWC within these parameters. Other
chock systems are not recommended.
The following are some recommendations that should be followed for the safety of the vessel and
personnel when the vessel is equipped with the optional swim platform lift system:
1 NEVER operate the lift with people on the platform or in the water in the vicinity of the platform.
2
The Power switch (location of this switch will vary according to the boat manufacturer specs)
provides electrical power to the Hydraulic Pump Unit (HPU). This switch should be in the “OFF”
position at all times except when the lift is in actual operation. When the PWC (Personal Water
Craft) is released in the water, the lift should be returned to the water line or all the way up and the
Power switch returned to the “OFF” position. All GHS systems are wired for optional radio
transmitters and a receiver that have a range of approximately 60-100 ft. under ideal conditions.
Returning the rocker switch to the “OFF” position will prevent the accidental and unintentional
movement of the platform.
3
The system includes 2 audible alarms that sound whenever the hydraulic system is activated.
This alarm is very annoying and is intended to be so. It alerts everyone in the vicinity that
platform is moving and caution is to be observed.
4
After launching your PWC, NEVER leave the platform in the down position. Always return the
platform to the waterline or all the way up. As a point of interest, most large swim platforms have
an area of approx 70 sq. ft.. When the platform is just 12” below the surface, there is a potential
load 4500 pounds on top of it. With the boat at anchor, we can experience acceleration loads that
exceed the limits of the system-so ALWAYS MOVE THE LIFT BACK TO AT LEAST THE
WATERLINE.
5
Never travel with a PWC or Dingy unless it is covered and the drain plug is pulled, a high volume
bilge pump is also recommended. Water weighs approximately 8 lbs per gallon. Your watercraft
can weigh 1000’s of lbs if full of water.
PAGE 3

SECURING YOUR PERSONAL WATERCRAFT (PWC)
TO THE SWIM PLATFORM
1
The optional chock system on your yacht is designed to safely support most Personal Watercraft
on the centerline of the swim platform. The system is also designed to be easily removed when a
PWC is not being used. By loosing only 4 ½” nuts, the chocks will slide aft and free of the tracks,
leaving the platform clear of all obstacles to use your platform for other activities. This feature is
only for easy removal and not intended to allow the PWC to be stowed anywhere but on the
centerline of the swim platform (See fig. 1 & 1A). Figure 1B shows an incorrect PWC installation.
CAUTION Moving the center of gravity of the PWC aft of the centerline of the swim platform can
cause damage or failure of either the lift assembly or the transom of the yacht.
2
Make certain that the chocks fit the bottom of the PWC hull. When the upper chock fits the PWC
bottom perfectly you will need to tighten the 4 ½” nuts (with a wrench) to the track. With the PWC
in place and all four ratchet straps tight, you will need to move the 3” round disc along the bottom
chock until it is tight against the top chock and the hole in the disc & bottom chock line up.
Secure these two into position with the ¼” fastener. Now line drill the disc and top chock with a
17/64” dill and secure with the fastener provided. Repeat this with all four chocks (See Fig. 2).
3
Secure the PWC to the chock system using the Stainless Steel ratchet straps provided with the lift
system option package. If you are going to stow anything other than a small two place PWC, you
should purchase the optional “HEAVY DUTY” tie down assembly. This assembly consists of 4
each 1” wide straps and Stainless Steel ratchets plus 5 additional “D” tie down rings. The “D”
rings are to be installed by the dealer and should be installed as in fig.1 so that the PWC cannot
move Port to Starboard, Fore and Aft, or rock in the chocks.
4
When the yacht is in transit and a PWC is stowed on the platform, it is prudent to occasionally
check the condition of the stowed PWC and if sea conditions worsen, the vessel should be
slowed to an appropriate speed.

HYDRAULIC PLATFORM LIFT
PRODUCT DESCRIPTION
The GHS Hydraulic Platform Lift is an electric/hydraulic system designed to safely lower your swim
platform below the water surface in order to launch various watercrafts. Your yacht builder has designed
and strengthened the transom of your yacht to allow the GHS Hydraulic Platform Lift system to be
attached to the transom and to operate with very specific maximum loads. Make certain that you consult
your yacht “Owners Manual” for this information. Operating the Lift outside of the designed maximum
limit may result in STRUCTURAL damage to the transom.
The Platform Lift System consists of the following major components:
A Power Unit Assembly
B Platform lift assembly
C Control Unit
The Power Unit Assembly is an integrated unit combining a 12V DC or a24V DC electric motor, a
hydraulic pump, a hydraulic manifold, a manual hydraulic pump and the necessary valves and relays to
allow the unit to function. The hydraulic manifold is a complex unit that routes and controls the flow of
fluid to the four hydraulic cylinders. All of the valves in the manifold are preset at the factory to function
at very precise pressures and are not to be adjusted in the field by anyone other than a factory authorized
representative. Any readjusting of these valves by someone other than an authorized representative will
void the warranty on the entire Lift Assembly and may cause serious damage to the lift and the vessel.
The Platform Lift Assembly consists of the following major components:
A Transom Brackets
B Platform Brackets
C Lift Cylinders
D Locking Cylinders
E Lift Arms
The above components are designed to act as one unit to allow hydraulic pressure to lower and raise the
swim platform under controlled conditions. Extreme caution must be exercised when this unit is moving
either up or down. The locking and lift cylinders are very powerful, operating pressures as high as 2500
PSI. A warning horn signals when the platform is moving in either the up or down direction to caution all
in the vicinity that the platform is moving and all should remain clear.The lift should never be operated
when personnel are on the platform.
The remote control unit is a hand-held UP/DOWN switch that is hard-wired to the Power Unit Assembly
through a disconnect mounted in the vicinity of the transom. In addition to the standard hard-wired
control, there is available an Optional Radio Remote Control that can operate the platform lift from
distances of approximately 60-100 feet.
SYSTEM FEATURES
1 Integrated Power unit-motor, pump, manifold, manual pump, valves and electronics
2 Hydraulic fluid filter
3 One year warranty
4 Manual/automatic selector valves
5 Manual emergency hydraulic pump-integral to the power unit
6 Heavy duty DC motor and pump
7 Compensating and equalizing valves to equalize and control pressure to the lift cylinders
8 Lift capacity approximately 700 pounds-depending on model
9 Total lift of 28 thru 46 inches depending on model
10 100% type 316L stainless steel and naval brass construction

OPERATIONAL PROCEDURES
NORMAL PROCEDURES
The GHS Hydraulic Platform Lift is designed for simple one hand operation. To safely LOWER the
platform, the following procedure MUST be followed: AFTER MAKING SURE THAT THE
PLATFORM AND AREA ARE CLEAR
1
Plug the hand held control unit into the receptacle located in the area of the transom. The
receptacle is located in this area so that the operator will have a clear view of the platform and the
adjacent areas.
2Make sure that the yacht’s engines are “OFF”.
3
Make sure that the platform has ample room to operate. The platform will move approximately 24
inches aft as it rotates to the down position.
4
Make sure that there is no debris or foreign matter in the two transom bracket mechanisms that
will affect the operation as the arms rotate. Serious damage may result from foreign matter
interference.
5
Make sure that no one is on the platform or in the water in the vicinity of the platform when it is in
operation. Serious injury is possible when the platform is moving.
6
After making certain that the platform area is clear, turn the lift Power switch to the ”ON” position
(location of this switch will vary according to the boat manufacturer specs). This will provide DC
power to the hydraulic power unit via the latching solenoid. The light on the Power switch
indicates that power is actually supplied to the Hydraulic Power Unit (HPU).
7
The current Hydraulic Power Units (boats built after Mar 2004) have a solid state controller. This
system must be Powered up prior to operation. To do this depress and hold the up or down
button for approximately five seconds, you should hear the audible alarm sound (beep). This is
required everytime the unit is Powered up .
`
8
While standing at the transom and observing that the platform area is clear, lower the platform
into the water to the desired depth by pushing the “DN” button on the hand held unit. It is good
practice not to pulse the unit as that will put unneeded loads on the Electrical /Hydraulic system.
Try to keep the button pressed until the platform is fully deployed / stowed.
9
When raising the platform, the same safety procedures must be followed as described in #2 thru
#6 of the above operational procedures. ABOVE ALL ELSE, BE ABSOLUTELY POSITIVE THAT
THE AREA IS CLEAR OF PEOPLE BEFORE RAISING PLATFORM.
10
When the lift is not in operation, the lift power rocker switch should be turned to the “off”
position. This will prevent any accidental operation of the lift. For instance, if a personal
watercraft has been lowered into the water and will be in the water for an extended period, the
rocker switch should be turned to "OFF” position.
IT IS THE OPERATOR’S RESPONSIBILITY TO INSURE THAT ALL SAFETY ITEMS ARE CONSIDERED BEFORE
OPERATING THE PLATFORM LIFT. THE OPERATOR SHOULD BE INFORMED OF ALL SAFETY PRECAUTIONS
AND SHOULD BE AWARE OF THE PHYSICAL DAMAGE THAT CAN OCCUR IF MATERIAL OR PEOPLE ARE IN THE
NEAR VICINITY OF THE LIFT WHEN IT IS IN OPERATION.
Warning: Do not operate yacht when platform is not up & locked.
PAGE 7

Emergency Procedures
The Hydraulic Platform is designed to give you years of trouble-free service but in the event of a failure, the
following procedures should be followed:
LOSS OF ELECTRICAL POWER OR FAILURE OF PUMP MOTOR
A Check circuit breaker usually located on the main DC circuit breaker panel in the engine room.
B
If the unit has been run repeatedly in a short period of time, let the unit cool down for 10 minutes and try the lift
again. In the event that your DC power supply or the pump motor fails, the lift cannot be operated in the “normal”
mode. It may be operated in the manual mode. To operate the unit in the manual mode, locate the Hydraulic
Power Unit Assembly (most often it is located in the engine room close to the transom) then do the following:
1 To manually raise the platform:
Insert the Emergency pump handle (black metal handle approx. 18” long) into the Manual Pump located on the
Hyraulic Power Unit (HPU). Turn the “knurled” red knob, located on the “UP” Solenoid, counterclockwise until it
pops up (about ¼ of a turn). You are now in the manual “UP” mode. Using the handle, pump until the unit is
completely up. You should hear the two locking cylinders engage the lock pins and the gage pressure should
approach 2500 PSI. When you are sure that the unit is locked in the up Position, push the red knob down &
clockwise until it returns to the original position. This procedure may take several minutes because of the low
flow rate of the hand pump. NOTE: When using manual mode, only one solenoid is allowed to be in “manual” at
a time.
2 To manually lower platform:
Insert the handle (black metal handle, approximately 18”Long) into the Manual Pump located on the side of the
power unit. Turn the “knurled” red knob, located on the “DN” solenoid, counterclockwise until it pops up (about
¼of a turn). You are now in the manual “DN” mode. Pump the handle until the unit unlocks and lock plates are
clear of locking pins on arms. Adjust sequence valve all the way out (count turns of set screw to redo setting)
pump to desired depth. When you are sure that the unit is down to the desired depth, turn the red knob down &
clockwise until it returns to the original position, reset sequence valve. You are now back into the normal mode.
NOTE: When either of the manual modes are selected, the pump will not operate in the normal (electric) mode
even though the motor may run.
3 UNEVEN MOVEMENT
One side of the platform moves faster than the other side.There is a possibility that one side of platform will move
at a different rate than the other. The Hydraulic Manifold contains combiner-divider valves (see page 17-31) that
regulate and equalize fluid flow to both lift cylinders. This valve is only 90% efficient, so you will notice some
slight difference in the movement of the individual sides. However this difference will be minimal and should not
affect the normal operation of the platform. If there is a significant difference in the rate of movement, try shifting
the load toward the faster side. If the problem persists, follow the recommendations in the “TROUBLE
SHOOTING GUIDE”.
4 LEAKING OR BROKEN HYDRAULIC LINE-DO NOT ATTEMPT TO OPERATE THE LIFT
If the platform is in the up position, and any line is broken or leaking DO NOT OPERATE THE LIFT. Contact your
dealer or GHS for help in determining if there is a serious problem. If the platform is down, it must be raised
before the engines are started. A broken or leaking hose must be replaced prior to operation.
5 PHYSICAL DAMAGE TO EITHER THE PLATFORM OR LIFT ASSEMBLY.
If the swim platform assembly has been damaged due to an accident etc., have the damage assessed by your
Dealer before operating the lift. Serious damage to the hull can result from operating the lift when it is
misaligned.
If the Lift should ever have any operational problems please reference the Owner’s manual /Trouble-
Shooting Guide to determine the cause of these problems and their solutions. General Hydraulic Solutions has all
necessary parts to help get your lift back in operation.

SERVICE
1 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.
2 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.
**See page 10 for information to help select the oil that will work best for you in your area
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.
4 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.

Recommended Hydraulic Oil For G.H.S. Hydraulic Swim Platform Lifts
1
We highly recommend using a NZ (non-zinc), AW (Anti-Wear) hydraulic oil. This material is not
expected to be harmful to aquatic organisms. The ECOTOXICITY hazard is based on an evaluation
of data for the components or a similar material and provides the lubrication your pump needs.
Use Mineral-Based or Synthetics with Lubricating Properties at Viscosities of 7.4 to 420 cST ( 50 to 2000 sus )
Viscosities of 7.4 to 420 cST = ISO Grade of 10, 15, 22, 32, 46, 68, 100, 150, 220, and 320. NO higher than 320
Viscosities of 50 to 2000 sus = ISO Grade of 10, 15, 22, 32, 46, 68, 100, 150, 220, and 320. NO higher than 320
Ask your local oil sales person to help pick the oil that will work best for you in your area and operating conditions.
2Monograde Hydraulic Oils
Monograde Hydraulic Oils are designated by one number (10,15,22,32, etc.) The number indicates a level of the oil
viscosity at a particular temperature. The higher the grade number, the higher the oil viscosity.
Use the chart below to determine witch viscosity grade will work best for you.
AW ISO 32,42, and 68 are the most commonly used oils.
AW ISO 32 covers between about 28deg.F to about 145deg.F It's a good colder weather oil.
AW ISO 42 covers between about 30deg.F to about 160deg.F It's a good worm weather oil.
AW ISO 68 covers between about 35deg.F to about 185deg.F It's a good hot weather oil.
( ISO ) Designation of hydraulic oils: International Standardization Organization
3Multigrade Hydraulic Oils
Multigrade Hydraulic Oils may be stabilized by polymeric additives(viscosity index improvers) . Viscosity of such
oils is specified at both high and low temperature. These oils are called multigrades and they are designated by
two numbers and the letter "W" ( SAE 5W30, SAE 10W20, SAE 10W30 etc.). The first number of the designation
specify the oil viscosity at cold temperature, the second number specifies the oil viscosity at high temperature.
For example: SAE10W30 oil has a low temperature viscosity similar to that of SAE 10, but it has a high
temperature viscosity similar to that of SAE 30 Multigrade Hydraulic Oils are used in a wide temperature range.
Remember to take into consideration the location of your hydraulic pump. If it is in the engine room, it will be
much wormer inside there. This will affect the viscosity of your oil.
Temperature Operating Window for Hydraulic System Operating at 45deg. F to 150deg. F
There are many oil manufacturers and types of hydraulic oil you can use. We will always recommend
using an ECOLOGICALLY SENSITIVE oil like the NZ (non-zinc) with AW ash less ( Anti-Wear )
additives.
PAGE 10

OPTIONAL RADIO REMOTE CONTROL
1
General Hydraulic Solutions uses an optional 2-channel radio remote for wireless operation of the
lift platform. The system consists of a receiver unit and two 2-button transmitter units. The remote
is FCC approved. These transmitters are water resistant and good for a range of 60-100 feet.
These transmitters should provide years of trouble free service, however, if the transmitters are
lost or damaged new ones may be purchased through General Hydraulic Solutions.
2
IMPORTANT:In order to program up to 4 Transmitters to one remote you must first “CLEAR” the
memory.
* Locate the program switch as shown below
* Press and hold the program switch for 10 seconds (the LED will go out).
* The unit is now clear
3REMOTE PROGRAMMING (programming must be completed within 10 seconds)
* Push the program switch till LED lights solid, then release.
* Push button one on remote transmitter until LED goes out, then release
* Push button one again the LED should flash slowly, then release
* Your remote is now programmed. Repeat for each transmitter.
Note: If the new remote does not work, make sure that the indicator LED on the remote is flashing and that the
batteries are good. Repeat step 3
