INSTALLATION AND SETUP
3.1. PRE-INSTALLATION CHECKS
1. Do not assemble the lift if any part shows any sign of damage.
2. Do not weld or otherwise modify the lift. Such alterations may weaken the structural integrity of the lift and void the
warranty.
3. All lifting accessories such as pontoon brackets, pivoting bunks, and guide-ons shall be commercially manufactured, and
be properly maintained and installed. Consult the manufacturer’s separate instructions provided for these accessories.
3.2. PRIOR TO SETUP
1. The assembly instructions refer to the placement of components in terms of forward, rear, right-hand and left-hand. The
rear of the lift corresponds to the rear of the boat. The rear is also where the cylinders are placed.
2. In choosing a place to assemble the lift, keep in mind the final placement of the lift. The lift may be placed on either side
of your dock and the boat must enter the rear of the lift.
3. This product has been supplied with stainless steel hardware to protect against a harsh marine environment and provide
outstanding performance. Due to the chemistry and surface condition of stainless steel, there is a natural tendency for the
hardware to “gall, lock up, or seize” during assembly. To prevent this from occurring, it is strongly recommended that
the anti-seize supplied in the hardware bag be applied to the mating surfaces of all stainless steel fasteners before
assembly. Lubricants containing molybdenum disulfide, graphite, mica or talc may also be used.
CAUTION:
DO NOT EXCEED THE MAXIMUM TORQUE RATING ON ALL BOLTS OF 20 FT-LBS.
WARNING:
FAILURE TO APPLY A SUITABLE LUBRICANT TO THE MATING SURFACES OF
STAINLESS STEEL THREADED FASTENERS MAY CAUSE GALLING AND/OR SEIZING OF
ASSEMBLY.

3.9. MAKING POWER CONNECTIONS
1. Before making any hydraulic connections, inspect all hydraulic lines, fittings and hoses for leaks and risks of rupture as
follows:
a. Inspect each hydraulic line, fitting, and hose for breaks, cracks, worn spots, bulges, chemical attack, kinks or any
other damage. Never try to stop any detected leak with any body parts. Do not put your face close to suspected
leaks. Hold a piece of cardboard close to suspected leaks and then inspect the cardboard for signs of hydraulic oil.
b. Replace a damaged line, fitting or hose immediately. Never repair the part.
WARNING:
LIQUID UNDER HIGH PRESSURE CAN PIERCE THE SKIN, CAUSING DEATH OR SERIOUS
INJURY. IN CASE OF INJURY, GET IMMEDIATE MEDICAL ATTENTION.
2. Wipe the mating surfaces of the hose couplings as well as the control box couplings with a clean rag prior to making
connection.
3. Insert the hoses through the flexible cable boot in the back of the control box. Connect the hose couplings.
4. If the quick connect fittings are difficult to attach, relieve some of the pressure in the system by pushing in on the tip of
the male hose connector. Pressing the tip against a clean hard surface is suggested. Use caution not to damage the
fitting. This will release a small amount of fluid, which is acceptable. Once the pressure has been released, you should
be able to connect both hoses.
WARNING:
ENSURE HYDRAULIC HOSES ARE PROPERLY CONNECTED AND IN GOOD CONDITION.
6. Ensure that the hydraulic fluid supply is adequate.
7. Attach the red battery lead to the positive battery terminal, and the black lead to the negative terminal. Tighten each
wing nut with a pair of pliers, as even a slightly loose connection can cause the battery terminals to heat up. Keep
battery terminals clean with a corrosion protective coating.
WARNING:
FOLLOW THE SAME SAFETY RULES WHEN WORKING INSIDE THE POWER SUPPLY BOX
AND AROUND THE BATTERY THAT APPLY TO ANY CAR OR BOAT BATTERY. A BATTERY
CAN EXPLODE AND CAUSE PERSONAL INJURY AND/OR EQUIPMENT DAMAGE.
9. Verify that the system is switched “on” using the on/off switch located inside the power supply box on the side of the
electrical control box.
10. If the optional solar panel is supplied, the solar panel must be mounted in a suitable location. Mount the solar panel so
that it faces toward the south and angled toward the afternoon sun. Route the plug end of the solar panel through the
flexible cable boot in the back of the control box. Connect to the mating connector in the wiring harness.
11. If the optional AC charger is supplied, mount the charger to left side of the box. Connect the red wire to the positive
battery terminal. Connect the black wire to the battery negative terminal. Run the AC power cord through the flexible
cable boot in the back of the control box and plug the AC charger in.
12. If the optional light bar will be used on the lift, route the light bar wire through the flexible cable boot in the back of the
control box and plug into the light connector. Using UV stabilized nylon cable ties, (black zip ties) attach the wire and
the hydraulic hoses to the lift frame.

OPERATION
4.1. BEFORE OPERATING THE LIFT
1. Review and follow all the safety precautions given in Chapter 1.
2. Do not use the lift if it shows any signs of damage.
3. Ensure that all bolts and nuts are fastened securely prior to operation.
4. Ensure that the frame is square and that the lift sits level. (see Sec. 3.11)
WARNING:
IF THE FRAME IS NOT SQUARE OR THE LIFT IS NOT LEVEL, BINDING MAY RESULT.
THIS CAN CAUSE PERSONAL INJURY AND/OR EQUIPMENT DAMAGE.
5. Never try lifting anything other than a boat with this lift.
WARNING:
NEVER TRY TO USE THIS EQUIPMENT BEYOND ITS RATED CAPACITY. THIS CAN
DAMAGE THE LIFT AND/OR BOAT RESULTING IN PERSONAL INJURY.
THE BOAT MUST BE PROPERLY POSITIONED ON THE LIFT BEFORE DOING ANY
RAISING OR LOWERING. FAILURE TO DO THIS CAN CAUSE PERSONAL INJURY
AND/OR EQUIPMENT DAMAGE.
6. Never try to lift or launch your boat in rough water conditions. This can damage your boat and/or the lift.
7. Follow the Pre-Lifting Checklist before operating.
8. Read and know the instructions and ensure that everyone understands the proper operating procedure.
9. Understand the use of all the controls and connections provided with the power supply and the remote transmitter.
4.2. TESTING LIFT OPERATION
After the lift installation is complete, it is important to test it for proper functioning before any load is applied. Proceed as
follows:
1. Use the up/down switch inside the control box to cycle the lift up and down. Ensure that the hydraulic hoses are not
binding or being pinched by any part of the lift.
WARNING:
DO NOT STAND OR WALK ON THE LIFT PLATFORM WHILE IT IS IN ANY RAISED
POSITION. THIS CAN CAUSE SERIOUS PERSONAL INJURY.
2. The loading platform should move up and down smoothly without excessive stress or squeaking. If there is excessive
squeaking or binding, check that all pivot pins are properly lubricated.
3. After cycling the lift a couple of times, inspect all hardware to ensure that they are still secure and tight. Also test the
remote control and underwater lighting system. Ensure the hydraulic fluid level in pump reservoir remains up to the base
of filler neck.
4. Contact your authorized dealer if the hydraulic system fails to perform as described in this section. Do NOT tamper with
either system.

14
4.3. TESTING LIFT WITH REMOTES
1. To unlock the remotes, press the two blue buttons simultaneously, this will unlock the unit.
2. Press the ‘UP’ button to raise the lift platform. Press the ‘DOWN’ button to lower the lift platform.
3. To lock the remote, press the two blue buttons simultaneously.
4.4. RAISING AND LOWERING THE BOAT
1. Position the boat so that the boat’s center of gravity is between forward and rear support legs.
2. Carefully raise the platform until the bunks “capture” the boat.
WARNING:
NEVER ALLOW PEOPLE IN THE BOAT ANY TIME IT IS SUSPENDED ABOVE THE WATER
ON THE LIFT.
3. Keep fingers and clothing clear of all moving parts. Keep people clear during operation of the lift.
4. Stop the lift again and check the stability of the lift. Ensure that it is remaining level and will not topple over.
5. Continue lifting the boat, closely observing the position of the lift, until the platform is in the fully upright and over
center position.
6. Remove the boat from the lift and check to see that the lift is still level. If not, the legs will have to be re-adjusted.
CAUTION:
ALWAYS ADJUST THE HEIGHT OF THE LIFT TO LIMIT WAVE ACTION AGAINST THE
HULL. WAVE ACTION CAN SERIOUSLY DAMAGE THE LIFT AND/OR YOUR BOAT.
7. Two weeks after installation, check to see that the lift is still level, as it may have settled over time. Readjust the legs as
described above and repeat this inspection and adjustment procedure at the frequency found necessary.
8. After removing the boat from the lift, re-tighten the bunk bolts as required.
4.5. SECURING LIFT WHEN NOT IN USE
1. Make the lift visible by leaving the platform in any elevated position when it is not loaded with a boat. This prevents the
lift from being a hidden underwater obstruction, and protects the bunks from prolonged water immersion.
2. Lock out your control box to prevent unauthorized use when your boat lift is unattended. Never assume you will find the
lift in the same condition that you left it.
3. When storing the boat on the lift, the following additional precautions must be observed:
a. When storing the boat, the platform must be in the upright over center gravity lock position for maximum safety.
The over center position will prevent the boat from lowering if any hydraulic leak occurs.
b. Position the boat on the platform so that the boat’s center-of-gravity is between the front lift arm and the rear foot
plates when in the down position.
c. Prevent rainwater from accumulating in your boat when leaving it on the lift for long term storage. A boat that has
water in it from a rainstorm could exceed the recommended weight capacity of the lift. Just 1 gallon of water
weighs over 8 pounds. Be sure to remove the plug while the boat is up on the lift. Make sure you replace the plug
prior to launching your boat.

NEVER ALLOW ANYBODY TO WORK IN OR ON THE BOAT WHEN IT IS SUSPENDED
ABOVE THE WATER ON THE LIFT.
WARNING:
BEFORE STARTING ANY MAINTENANCE ON THE LIFT, DISCONNECT AND LOCK OUT
THE POWER SUPPLY TO PREVENT ACCIDENTAL OPERATION.
3. Immediately replace any components found to be defective.
CAUTION:
POOR OR IMPROPER MAINTENANCE CAN LEAD TO EQUIPMENT DAMAGE OR
FAILURE.
4. Do not weld or otherwise modify the lift. Such alterations may weaken the structural integrity of the lift and invalidate
your warranty.
5.2. CONTROL BOX MAINTENANCE
Refer to the hydraulic control box manual for important information on the maintenance and operation of the batteries,
control box, and remote control.

16
5.3. ANNUAL INSPECTION
At least once a year, the lift must be thoroughly inspected using the following procedure.
WARNING:
DO NOT ALLOW ANYBODY TO USE THE LIFT UNTIL THIS MAINTENANCE IS
COMPLETED.
1. Tighten all bolts.
2. Clean cylinder rods.
3. Check that all the pivot pins are lubricated properly.
4. Check frame thoroughly for defects.
5. Inspect all hydraulic lines, fittings and hoses for leaks and risks of rupture as follows:
c. Inspect each hydraulic line, fitting, and hose for breaks, cracks, worn spots, bulges, chemical attack, kinks or any
other damage. Never try to stop any detected leak with any body parts. Do not put your face close to suspected
leaks. Hold a piece of cardboard close to suspected leaks and then inspect the cardboard for signs of hydraulic oil.
WARNING:
LIQUID UNDER HIGH PRESSURE CAN PIERCE THE SKIN, CAUSING DEATH OR SERIOUS
INJURY. IN CASE OF INJURY, GET IMMEDIATE MEDICAL ATTENTION.
d. Replace a damaged line, fitting or hose immediately. Never repair the part.
5.4. STORAGE PROCEDURE
CAUTION:
DO NOT STORE THE LIFT IN THE WATERWAY IF FREEZING TEMPERATURES ARE
EXPECTED. THIS WILL CAUSE EQUIPMENT DAMAGE.
1. Wipe cylinder rods before storing hydraulic lift at the end of the season.
2. Disconnect and store battery fully charged to prevent from freezing.
3. Disconnect and store hydraulic cylinders, hydraulic hoses, and control box in a warm dry area if temperatures below
-20°F are expected.

17
5.5. HYDRAULIC SYSTEM FLUSH
It is recommended that as part of an annual maintenance program, the hydraulic system be drained and fresh Vegetable Grade
hydraulic oil installed. RGC recommends CITGO Aqua Marine Hydraulic 46 (or equivalent biodegradable oil) be used.
1. Lower the platform until the cylinders are fully retracted.
WARNING:
FOLLOW THE SAME SAFETY RULES WHEN WORKING INSIDE THE CONTROL BOX AND
AROUND THE BATTERY THAT APPLY TO ANY CAR OR BOAT BATTERY. A BATTERY
CAN EXPLODE AND CAUSE PERSONAL INJURY AND/OR EQUIPMENT DAMAGE.
2. Disconnect couplings between cylinder hoses and control box.
3. Unscrew reservoir oil fill cap.
4. Siphon old oil from reservoir using a hand siphon or vacuum pump. If not available, remove the 12-volt battery from
control box, and very carefully tip over the control box to drain oil from reservoir into a bucket.
5. Remove reservoir from pump assembly to inspect oil filter screen every two years. Be careful not to damage O-ring seal
for reservoir. If necessary, clean the filter screen with soap and water.
6. Reassemble reservoir and pump assembly, then fill reservoir with fresh CITGO Aqua Marine Hydraulic 46.
WARNING:
LIQUID UNDER HIGH PRESSURE CAN PIERCE THE SKIN, CAUSING DEATH OR SERIOUS
INJURY. IN CASE OF INJURY, GET IMMEDIATE MEDICAL ATTENTION.
7. Depressurize cylinder hoses as follows:
a. Depressurize the cylinder hose with male coupling by wrapping a rag around the coupling (to prevent spray) and
carefully pressing the end button against a hard flat surface. Use caution to avoid damaging the coupling button.
b. Depressurize the cylinder hose with female coupling by wrapping a rag around coupling (to prevent spray) and
carefully press the internal button using a 3/8” bolt. Be very careful not to damage the internal O-rings. Be sure that
both couplings are kept clean at all times.
9. Clean the lower cylinder hose coupling and reconnect to the control box.
10. Connect a spare coupling or remove quick-disconnect from the upper cylinder hose assembly.
11. While holding open hose end over a suitable container, press the UP button until cylinders are fully extended.
12. Reverse the hoses so that the spare fittings are on lower cylinder hose.
13. Be sure to keep reservoir filled with new oil.
14. While holding open hose end over a suitable container, press the DOWN button until cylinders are fully retracted.
15. Repeat steps 10 to 13 until oil coming from disconnected hose is clean. Then reconnect hose couplings to control box.
16. As these procedures are performed, additional oil may need to be added to the reservoir. Perform a final check of oil
level with cylinders fully retracted.

TROUBLESHOOTING
The following chart is intended to assist with troubleshooting your hydraulic lift. While not all inclusive, the chart outlines
the most common causes of a problem and the recommended course of action.
Note: Disassembling the power supply may invalidate its warranty. Consult manufacturer’s warranty before attempting any
repair or maintenance.
SYMPTOM
CAUSE AND CORRECTIVE ACTION
Hoses cannot be connected.
System is pressurized. Depressurize the hoses as follows:
a. Depressurize the male fitting by carefully pressing the button on the end of the
nipple or by briefly tapping the down switch. Use caution to avoid damaging the
nipple button.
b. Depressurize the female fitting by tapping the “up” switch briefly, which will
depressurize the pump. If necessary, depressurize the female fitting on the hose by
carefully pressing the internal button using a 3/8” bolt. Be careful not to damage the
internal O-rings. Wrap the fitting with a rag while depressurizing to prevent spray.
Keep the connectors clean.
Battery does not keep a charge.
Check the battery fluid levels, age, and time of last booster charge. The battery must be
booster charged at the beginning and end of the season using a 10A charger.
Verify solar panel or AC charger is plugged in correctly.
Check the voltage output of the solar panel. Output should be about 14-18 volts when
exposed to light.
Verify that the polarity (positive or negative) of the solar panel matches the battery’s
polarity.
Verify that the solar panel gets an adequate amount of light and the lift usage is within the
monthly seasonal limits. The solar panel may be mounted up to 50 feet away from the
battery if necessary. You may also order a bracket to mount the solar panel on top of the
canopy. The remote control should only be drawing about 5 mA, and the pump 20 mA. The
solar panel has an output of about 750 mA in direct sunshine.
Battery terminal becomes hot.
Verify cable is clean and tight on battery terminal
Remote control not functioning.
The remote control is designed to stop working if the battery drops below 11 volts to alert the
user that the battery is getting low. If the lift operates with the up/down switch in the power
supply, but not with the remote, charge the battery using a 10A booster charger.
Remote control range is limited.
Check battery in key chain transmitter. If the range is only limited while in your boat, try
holding the transmitter over your head. Proximity to cell phone towers, power lines, and
other electromagnetic interference can also reduce remote control range.
Fluid overflows reservoir.
It is normal to see some fluid overflow from the reservoir when the platform is cycled all the
way down the first few times.
Lift stops after a split second.
Battery is low. If the battery is becoming low, the remote control will stop functioning at
about 11 volts. The lift can still be operated using the up/down switch in the power supply,
