Specific Safety Precautions

WARNING! DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to the tool safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

1. Use the correct tool for the job. This tool was designed for a specific function. Do not modify or alter this tool or use it for an unintended purpose.
2. Do not use the tool if any parts are damaged, broken, or misplaced. Repair or replace the parts.
3. The maximum lifting capacity is 1 ton. Know the weight of the load being lifted. DO NOT overload the crane beyond the rated capacity of each specified boom position. Overloading can cause damage or failure of the crane.
4. Do not use this crane to support a load. It is only designed for lifting, lowering and transporting a load within the shop.
5. Use only slings, levelers or chains with a rated capacity greater than the weight of the load being lifted.
6. Do not stand under or work under a raised load; serious personal or property damage could occur.
7. Stabilize the load. Ensure that the load remains stable at all times. Lift deadweight only.
8. Do not move a load with the boom raised; serious personal or property damage could occur. Lower the load and boom before moving the shop crane. Move the load slowly and smoothly to avoid uncontrolled swinging and possible loss of load.
9. Do not allow the load to swing or drop violently while lowering or moving the shop crane; serious personal or property damage could occur.
10. Make sure there is enough clearance around the crane and the load for movement.
11. Before lowering load, ensure that there are no obstructions underneath and that all people are standing clear.
12. Inspect the shop crane before each use. DO NOT use if bent, broken, cracked, leaking or otherwise damaged, any suspect parts are noticed, or it has been subjected to a shock load.
13. Check to ensure that all applicable bolts and nuts are firmly tightened.
14. Never stand directly in front of a loaded shop crane and never leave a loaded shop crane unattended.
15. Do not use brake fluid or any other improper fluid and avoid mixing different types of oil when adding hydraulic oil. Only good quality hydraulic jack oil can be used.
16. Store the crane with the boom in the fully lowered position and hydraulic ram valve closed when not in use.

Hydraulic Precautions

DANGER! Seek immediate medical attention if hydraulic fluid under pressure penetrates your skin. See Injection Injury precautions for instructions before using a pressurized hydraulic system.

1. Do not touch or handle hydraulic hoses or components while under pressure. Hydraulic fluid escaping under pressure has sufficient force to penetrate your clothing and skin. A pinpoint hole may inject hydraulic fluid into your body. Seek immediate medical attention if this occurs (see Injection Injury).
2. Never exceed the hydraulic system's load capacity (see Specifications).
3. Do not adjust the hydraulic system's relief setting. The settings are preset by the factory.
4. Hydraulic oil under pressure is hot and can cause a burn injury if touched, sprayed, or spilled. Allow the hydraulic system to cool before conducting maintenance.
5. Hydraulic components require regular inspection. Release all pressure from the system before you inspect it. Replace damaged hydraulic parts with identical manufacturer's components.
6. Do not attempt makeshift repairs to a hydraulic system. Such repairs can fail suddenly and create a hazardous condition.
7. Hydraulic fluid has a combustible flash point of 200°F (93°F). Do not expose the fluid to an ignition source.
8. Change your clothing immediately if sprayed with hydraulic fluid. Store clothing or rags contaminated with hydraulic fluid in an approved metal safety can with a spring-closing lid and venting designed to contain a fire.

Injection Injury

DANGER! Seek immediate, professional medical treatment if fluid penetrates your skin. It may feel like a pricking or sting. Do not wait for the appearance of symptoms. A toxic reaction can occur from the exposure. Delay in treatment can lead to amputation or death.

Inform the medical staff that you have a fluid penetration injury as soon as you arrive at the medical facility. The severity of the symptoms will depend on the type of fluid injected. Bring the Safety Data Sheet for the fluid with you to the medical facility if possible.

Injection Precautions

Fluid can penetrate the skin at 100 PSI pressure. Fluid escaping under pressure from the tool has sufficient force to penetrate your clothing and skin. Follow the precautions below to avoid an injection injury.

1. Always check for leaks wearing a face shield, safety goggles, rubberized gloves and protective clothes.
2. Release all pressure from the system before you inspect it.
3. Do not use your hands to detect a fluid leak. Use a large piece of wood, cardboard or paper and watch for discolouration.
4. Replace damaged parts with identical manufacturer's components to ensure it is rated to handle the pressure.

Unpacking

WARNING! Do not operate the tool if any part is missing. Replace the missing part before operating. Failure to do so could result in a malfunction and personal injury.

Remove the parts and accessories from the packaging and inspect for damage. Make sure that all items in the parts list are included.

Support Brackets Installation

1. Place the main post (#20) on the base. Do not tighten the screw and leave a gap between the main post and the base.
2. Assemble the handle (#18) and connecting rod (#31) to the main post (#20). Adjust the main post to match the holes in the line.

Operation

The boom length can be extended, but doing so reduces the maximum weight it can lift. The boom has the max. weight listed beside each bolt hole.

1. Purge air from the hydraulic system before first use. See Bleeding the Hydraulic System in the Maintenance section.
2. Position the hook (#1) above the load. The hook can either attach to the load directly if there is an appropriate attachment point or a harness (chain or otherwise) may be attached to the hook.
3. Ensure the load is balanced so it does not shift or fall when being raised, lowered or moved.
4. Turn the hydraulic jack's release-valve clockwise to raise the boom.
5. Insert the handle (#22) into the ram unit (#21) and pump until there is tension on the chain, but before the load is lifted. Double check the hook or harness to ensure the connection is correct.
6. Slowly pump the handle to raise the load enough to clear any obstacles between the lift point and the final destination.
7. Remove the handle and stow in the bracket on the main post (#20).
8. Push/pull the crane to the destination. Move slowly to prevent the load from swinging. Stop moving if the load begins to swing and do not resume until it the load is still. Resume moving, but at a slower pace.
9. Lower the boom arm by gradually turning the hydraulic jack's release valve counterclockwise. Pause lowering and position the load before allowing it to come to a rest.
10. Unhook the crane from the load and lower the boom completely to protect the ram from corrosion.

Care & Maintenance

1. Maintain the tool with care. A tool in good condition is efficient, easier to control and will have fewer problems.
2. Inspect the tool components periodically. Repair or replace damaged or worn components. Only use identical replacement parts when servicing.
3. Follow instructions for lubricating and changing accessories.
4. Only use accessories intended for use with this tool.
5. Maintain the tool's labels and name plates. These carry important information. If unreadable or missing, contact Princess Auto Ltd. For replacements.

WARNING! Only qualified service personnel should repair the tool. An improperly repaired tool may present a hazard to the user and/or others.

Hydraulic Ram Maintenance

Monthly maintenance is recommended for the hydraulic ram. Any restrictions due to dirt, rust, etc. can cause either slow movement or extremely rapid jerks, damaging the internal components. The following steps are designed to keep the pump maintained and operational.

1. Lubricate the cylinder and the pumping mechanism with light oil.
2. Visually inspect for cracked welds, bent, loose, missing parts or hydraulic oil leaks.
3. Inspect the hydraulic ram immediately if it was subjected to an abnormal load or shock load.
4. Remove any hydraulic pump from service that is damaged, worn down or operates abnormally, until repaired by an authorized service technician.
5. Check and maintain the ram oil level.
6. Always store your crane with the hydraulic ram in the fully retracted position. This will help protect critical areas from corrosion.
7. Do not use brake or transmission fluids or regular motor oil as they can damage the seals. Always purchase and use products labeled Hydraulic Oil.

Bleeding the Hydraulic System

Bleed excess air from the hydraulic system as follows:

1. Open the release valve (#36) by turning it counterclockwise.
2. Remove the oil filler screw (#35) and fill the pump with hydraulic fluid.
3. Wait 5 minutes for trapped air to rise to the surface.
4. Pump the handle or pedal for several full strokes to eliminate any air in the system.
5. Check the oil filler hole and if necessary, top off with more hydraulic oil.
6. Restore the oil filler screw. Close the release valve by turning clockwise.
7. Test the ram several times for proper operation before putting it into use. Do not use the ram if it still does not appear to be working properly. Have a qualified service technician service or repair the hydraulic system.

Folding the Legs

Starting with the legs fully extended, remove the pins and R-pins (Fig. 1-1) directly above the 2-1/2 swivel wheels.

Lift one leg upwards until it is perpendicular to the base. Secure the leg in place by reinstalling the pin and R-pin into the bolt hole indicated in Fig. 2-1. Repeat the process on the other side.

Lubrication

Inspect and lubricate the tool when required. Only use light oil to lubricate all moving parts.

Disposal

Recycle a tool damaged beyond repair at the appropriate facility. Contact your local municipality for a list of disposal facilities or by-laws for electronic devices, batteries, oil or other toxic liquids.

IMPORTANT! DO NOT pollute the environment by allowing uncontrolled discharge of waste oil.

Disposal of Hydraulic Fluid

Do not drain hydraulic oil into the sewer system or dispose in an uncontrolled location. Hydraulic fluid may take up to a year to breakdown in the environment and the ingredients may still be toxic. Contact your local municipality for proper disposal instructions or locations.

Troubleshooting

Visit a Princess Auto Ltd. location for a solution if the tool does not function properly or parts are missing. If unable to do so, have a qualified technician service the tool.
