Message to the Trailer Manufacturer

This manual contains instructions on how to correctly install and operate the Telescopic Cylinder system. These instructions are generalized, as each trailer is manufactured differently.

This manual does not outline the operation of the hydraulic system, as there are many different types of hydraulic systems available and supplied by Primary Mover. It is important that the hydraulic system operation manual be supplied to the end user, along with this manual.

Some trailer manufactures will purchase and install a hydraulic system not supplied by Primary Mover. In this case, it is your responsibility to obtain the correct manual for the installation and operation of the hydraulic system. The hydraulic system manual should be supplied along with this manual and made available to the end user.

The safety signs supplied with the kit are general in nature and are for use with the kit.
Because trailers vary between manufactures, it is the responsibility of the manufacturer, not Primary Mover, to ensure that correct safety signs and warnings are obtained.

Safety Precautions

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 Primary Mover with any questions.

Overloading a trailer could cause vehicle or trailer component damage resulting in injury or death. NEVER exceed the gross vehicle weight (GVW) or gross axle weight (GAW) rating of the trailer or your vehicle.

Damage to brake lines during manufacturing and installation of this equipment, 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 equipment, and take precaution to ensure that installed equipment does not interfere with 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, synfuel 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.

Never attempt to jerk or shock the trailer body with the body raised to remove a stuck load. Jerking or shocking the trailer in this position can cause damage that could result in injury or even death. NEVER drive forward or reward and stop quickly to “un-stick” the load. If load is stuck, lower trailer body and free load

Safety Arm Installation and Use

Always support an unloaded body with the safety arm. The safety arm is meant to support the weight of an unloaded body only.

Being under a raised body could result in serious injury or death should the body unexpectedly descend. Never position yourself or allow others to position themselves under a loaded body. Al- ways support an unloaded body with the supplied safety arm. NEVER use the safety arm on a loaded body.

Safety Arm Use:

1. Raise trailer body to sufficient height and shut off hydraulic power to hoist.
2. Grasp safety arm and rotate into the up/vertical position.
3. Once vertical position is accomplished, push arm down into the support bracket at base of arm.
4. SLOWLY lower the body until the cup contacts the vertical facing arm.
5. NEVER HOLD DOWN THE DOWN BUTTON on the remote control after the body contacts the safety arm. Doing so will bend the safety arm or bracket.
6. Reverse the above procedure to place arm back in its hanger for transport (be sure to body to full down position upon placing arm back in hanger).

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 HPU for mounting, electrical, wireless remote and hydraulic fluid requirements.

All HPU, hoses and fittings between HPU and cylinder are supplied by Primary Mover.

If hydraulic components other than those supplied by Primary Mover are used in the hydraulic circuit, it is the purchaser’s responsibility to verify that the components are compatible with the components supplied by Primary Mover. Incompatible components may cause failure of the direct push cylinder that, in turn, may cause damage to the trailer, vehicle, other property, and may cause injury or death.

Connecting the cylinder to a hydraulic system with more pressure (PSI) or flow (GPM) than is recommended by Primary Mover could cause the cylinder to fail during operation. This could lead to damage, serious injury, or death. Be sure you have correct pressure and flow before operation. Consult Primary Mover if you are unsure about your hydraulic system.

Adjusting the hydraulic pressure to more than the recommended setting could cause the cylinder to fail during operation. This could cause damage, serious injury, or death. NEVER adjust the pressure 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 by Primary Mover consists of components (pump, valves, reservoir, hoses, cylinder, etc.) that are designed to be compatible with each other.

All Primary Mover’s system liability and warranty will be voided, if determined by Primary Mover, that substituted hydraulic components were used that were incompatible with those supplied by Primary Mover.

Hydraulic Power Unit parameters are listed on the next page. These are listed as a general guide to ensure proper compatibility (when using other hydraulic components). If you have any questions, please contact Primary Mover.

Telescopic Cylinder Bleed Procedure

1. The highest point of the hydraulic circuit is the telescopic cylinder bleed screw.
   Remove the bleed screw and sealing washer.

2. Gradually fill the cylinder by pressing the “UP” button on the remote control station. This should be done in an intermittent manner with a rag over the bleed screw hole. Fluid will come out of the bleed screw hole at high velocity if the cylinder is filled too quickly. Keep fluid in the reservoir to prevent air from entering system.

3. Once a steady stream of fluid comes out the bleed screw hole, stop filling and install and tighten bleed screw.

4. Press and hold the “UP” button and keep the oil reservoir filled just enough to keep air out of system. Fully extend the cylinder.

5. Press and hold the “DOWN” button until cylinder is fully retracted. Watch oil reservoir level in case of overflow.

6. To remove any remaining air in the system, fully retract the cylinder and remove bleed screw. Repeatedly tap “UP” button until only fluid is coming out of bleed screw hole. Replace bleed screw.

7. Wipe cylinder clean and replace any lost oil.

8. Fully extend the cylinder. The cylinder should extend smoothly without any jerky motion. Watch oil level in reservoir. If cylinder has a jerky (stop and go) motion, retract the cylinder and repeat steps 6 thru 8 until cylinder operated smoothly.

9. Check oil level in reservoir. Bleed procedure is complete.

Battery Hookup Single Acting HPU

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 power unit.

Mount battery in a weather tight enclosure on the trailer. See additional instructions supplied with the HPU for mounting, electrical and hydraulic fluid requirements.

It is highly recommended that the trailer battery be kept charged using one of the Pulse tech products shown on Primary Mover website at http://www.primarymover.com/
