SAFETY PRECAUTIONS

WARNIN G

• Installing or operating this equipment without first understanding proper installation and operation procedures could lead to serious injury or death. Always read and fully understand all installation and operation manuals before installing or operating this equipment. Contact Premium Supply with any questions.
• Damage to brake lines during manufacturing and installation of the jack, as well as installing any hardware (bolts, nuts, brackets) in a way that they may rub and damage the brake system, could lead to brake failure. This can cause an accident that could cause injury or death. ALWAYS take adequate steps to prevent brake system damage during installation of the jack, and take precautions to ensure that installed equipment does not interfere with the brake system.
• Malfunctioning equipment could cause property damage, injury or death. ALWAYS have faulty equipment repaired before continuing use. Consult the trailer manufacturer if required.
• Welding, oxy-fuel cutting, or grinding could cause fuel to ignite. This could lead to injury or death. ALWAYS take adequate steps to avoid the ignition of fuel from fuel tanks when welding, oxy-fuel cutting, and/or grinding during installation.
• Heat from the vehicles exhaust system could cause hydraulic component failure. This could lead to a fire that can lead to injury or death. ALWAYS install equipment in locations where the exhaust system heat will not damage any components critical to operation.

DUAL OR SINGLE-ACTING HYDRAULIC POWER UNIT INSTALLATION
Mount HPU (hydraulic power unit) in a weather tight enclosure on the trailer. See additional instructions supplied with the Jack for mounting, electrical, wireless remote and hydraulic fluid requirements.

• CAUTION If hydraulic components other than those supplied by Premium Supply are used in the hydraulic circuit, it is the purchaser’s responsibility to verify that the components are compatible with the components supplied by Premium Supply. Incom- patible components may cause failure of the jack that, in turn, may cause damage to the trailer, vehicle, other property, and may cause human injury or death.

WARNING

• Connecting the jack to a hydraulic system with more pressure (PSI) or flow (GPM) than is recommended by Premium Supply could cause the jack to fail during operation. This could lead to damage, serious injury, or death. Be sure you have correct pressure and flow before operation. Consult Premium Supply if you are unsure about your hydraulic system.
• Adjusting the hydraulic pressure to more than the recommended setting could cause the jack to fail during operation. This could cause damage, serious injury, or death. NEVER adjust the pres- sure on your own. Consult the trailer manufacturer if the hydraulic pressure is in question. Only qualified personnel should adjust the hydraulic pressure. NEVER adjust the pressure to more than the recommended amount.

Hydraulic System Pre-Operation
The hydraulic system supplied with the trailer jack manufactured by Premium Supply consists of components (pump, valves, reservoir, hoses, cylinder, etc.) that are de-signed to be compatible with each other. All Premium Supply’s trailer jack liability and warranty will be voided if determined by Premium Supply that substituted hydraulic components were used that were incompatible with those supplied by Premium Supply. Jack hydraulic parameters are shown on the following pages. These are listed as a general guide to ensure proper compatibility (when using other hydraulic components). If you have any questions, please contact Premium Supply.

Bolt to trailer frame using the mounting bracket locations as it works for your specific application (hardware not included). (For direct weld applications follow ASTM for welding to carbon and low alloy steel tubes. Weld per specific application. Weld however should not exceed 1” from the top of the outer tube nor 1” from the bottom of the outer tube.

After bolting the jack to the trailer: With supplied hardware attach the housing and unit to the jack. Up body, hose is attached to extend port “raising” on the hydraulic jack (bottom port on jack). (hose supplied) Attach another end to Port A of Jack unit. Torque both connections to 18 ft-lbs.

BATTERY HOOKUP AND OIL FILL LOCATION

Down body hose is attached to retract port “lowering” on the hydraulic jack (upper port on the jack). (hose supplied) Attached other end of the hose to Port B of Jack unit. Torque both connections to 18 ft lbs. Using full size deep cycle RV/Marine battery (not supplied) run battery positive (red) and negative (black) battery cables (not supplied) to the Jack unit. Should also install insulating boots (not supplied) after connecting battery cables to HPU Unit.

WARNING

Shorting of the electrical system could cause a fire or equipment damage that could lead to injury or death. ALWAYS disconnect the battery prior to installing, servicing, or repairing the power unit. Mount battery in a weather tight enclosure on the trailer. See additional instructions supplied with the Jack for additional electrical and hydraulic fluid requirements.  See the top of the reservoir for instruction to ensure optimum performance and system life. Do not use biodegradable hydraulic fluid. Do not mix hydraulic fluids.

Battery Cables
To minimize voltage drop, increase the gauge size of the battery cables as the length of the positive and ground cables increase. Low voltage will cause the motor to run higher amps causing damage to other electrical components .

Bleed Cycle Instructions

• Remove the breather cap to view the hydraulic fluid while operating the hydraulic power unit
• Press the up button on the remote pendant and run hydraulic jack or hoist cylinder 1/3 of the way up. You may see fluid returning into the reservoir. If you see air pockets or aeration of the fluid, stop and allow the fluid to settle and continue to raise 1/3 way up.
• Once 1/3 of the way up, press the down button to return fully seated position of the hydraulic jack or hoist cylinder.
• Make sure the fluid level does not drop below the half full level of the reservoir while running the power unit
• Press the up button again on the remote pendant and run hydraulic jack or hoist cylinder 2/3 of the way up. Once 2/3 of the way up is reached, press down button on the remote pendant to a fully seated position again.
• Again make sure the fluid level doesn’t drop below the half full level of the reservoir
• Press the up button again on the remote pendant and run hydraulic jack or hoist cylinder to full stroke
• While running and if you see any air pockets or aeration of the fluid in the reservoir, stop and let the fluid settle, then continue to raise the hydraulic jack or the hoist cylinder
• You may have to repeat this process more than once to completely purge all the air out of the system

15K Hydraulic Jack Operation and Maintenance

Before operating the hydraulic jack, make sure the trailer is on a flat/even surface. Make sure that surface is capable of holding the weight of the trailer. Do not lubricate tubes on jacks. It can attract dirt which could affect the operation of the jack. After all, steps are completed, using supplied hardware attach the front metal panel over Jack housing.

Troubleshooting

If the jack is not extending or retracting check the following:

• Make sure all electrical connections are secure and battery is fully charged and grounded.
• Make sure hydraulic fluid is flowing from the Jack unit and through the lines. Check to make sure there are no leaks or pinch points in the hoses and all hydraulic connections are secure.
• If jack retracts after leveled to desired location, check fluid level in the Jack unit and all connections are secure.
