Norco 72200D Heavy Duty 22 Ton Air/Hydraulic Floor Jack Instruction Manual

1. Introduction

The Norco 72200D Heavy Duty 22 Ton Air/Hydraulic Floor Jack is engineered for robust lifting applications, specifically designed for heavy-duty trucks, agricultural machinery, and construction equipment. This versatile jack combines air and hydraulic power to provide efficient and reliable lifting. Its design incorporates features for ease of use, durability, and safety, making it an essential tool for professional environments.

Key features include a 50-inch long 'T' handle for optimal positioning, a load release mechanism integrated into the handle for precise control, and a handle locking lever that secures the handle in vertical, horizontal, or 45-degree positions. The compact design allows for easy maneuverability, even between tandem wheels. The jack is equipped with a rust-inhibitive coating on the ram and extension screw for extended life, large diameter wheels for easy transport, and a self-retracting ram to eliminate manual lowering. Safety is paramount, with a built-in safety by-pass system to prevent cylinder damage and a safety overload system to ensure the jack is not used beyond its rated capacity. An integrated filter protects the air motor, which provides fast lifting capabilities. The unit also comes with three removable 2-inch diameter saddles (3/4-inch, 2-1/4-inch, and 4-inch in height) and a convenient handle-mounted saddle holder.

2. Safety Precautions

Always prioritize safety when operating heavy lifting equipment. Failure to follow these instructions may result in serious injury or property damage.

• Read the Manual: Before operating the jack, read and understand all instructions and warnings contained in this manual.
• Rated Capacity: Never exceed the rated capacity of 22 tons (44,000 lbs). Overloading can cause jack failure and severe injury.
• Stable Surface: Use the jack only on a hard, level, and stable surface capable of supporting the load. Avoid soft ground, uneven surfaces, or inclines.
• Support the Load: After lifting, always immediately support the vehicle or load with appropriate jack stands. Do not rely solely on the jack to hold the load.
• Proper Placement: Position the jack saddle correctly under the vehicle's designated lifting points as specified by the vehicle manufacturer.
• Clear Area: Ensure the area around the jack and load is clear of personnel and obstructions during lifting and lowering operations.
• Personal Protective Equipment (PPE): Wear appropriate safety gear, including safety glasses and gloves.
• Inspect Before Use: Before each use, inspect the jack for any signs of damage, leaks, or wear. Do not use a damaged jack.
• Air Supply: Ensure the air supply is clean, dry, and at the correct pressure for optimal performance and to protect the air motor.
• Proposition 65 Warning: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.

4. Setup and Assembly

The Norco 72200D jack comes largely pre-assembled. Follow these steps for initial setup:

1. Unpacking: Carefully remove the jack and all components from the packaging. Inspect for any shipping damage.
2. Handle Assembly: Insert the T-handle into the handle receiver on the jack. Secure it using the provided locking mechanism or pin, ensuring it is firmly seated.
3. Air Supply Connection: Connect a suitable air hose (not included) to the air inlet fitting on the jack's handle. Ensure the air supply is clean, dry, and regulated to the recommended pressure (refer to specifications for exact pressure).
4. Saddle Placement: Select the appropriate saddle for your lifting application and place it securely on the jack's lifting ram. The unused saddles can be stored in the handle-mounted saddle holder.
5. Purge Air (Initial Use): Before first use, or after extended storage, it is recommended to purge any air from the hydraulic system. With the jack fully lowered, open the release valve slightly and pump the handle several times to circulate the fluid and remove air bubbles. Close the release valve.

5. Operating the Air/Hydraulic Floor Jack

Follow these steps for safe and effective operation:

5.1. Lifting a Load

1. Prepare the Vehicle/Load: Ensure the vehicle is on a hard, level surface. Engage the parking brake and block wheels that will not be lifted.
2. Position the Jack: Roll the jack under the vehicle, positioning the saddle directly under the manufacturer's recommended lifting point. Use the 50-inch T-handle to maneuver the jack precisely.
3. Connect Air Supply: Ensure the air hose is securely connected and the air supply is turned on.
4. Engage Lifting: With the release valve fully closed, activate the air motor by pressing the air control lever or by pumping the handle manually. The jack will begin to lift the load.
5. Lift to Desired Height: Continue lifting until the load reaches the desired height. Do not lift beyond the jack's maximum lifting height or rated capacity.
6. Secure the Load: Immediately place appropriately rated jack stands under the vehicle's designated support points. Once the load is safely supported by the jack stands, slowly lower the jack until the load rests firmly on the stands.

5.2. Lowering a Load

1. Clear Area: Ensure the area around and under the load is clear of personnel and obstructions.
2. Raise Slightly: If the load is resting on jack stands, lift the load slightly off the stands using the jack.
3. Remove Jack Stands: Carefully remove the jack stands from under the vehicle.
4. Lower the Load: Slowly open the load release valve on the top-mounted T-handle. Control the rate of descent by adjusting the valve. Do not open the valve too quickly, as this can cause the load to drop rapidly.
5. Fully Retract: Once the load is fully lowered, ensure the jack's ram is fully retracted.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your Norco 72200D jack.

• Cleanliness: Keep the jack clean and free of dirt, grease, and debris. Wipe down the ram and other exposed parts after each use.
• Lubrication: Periodically lubricate all moving parts and pivot points with a light machine oil.
• Hydraulic Fluid: Check the hydraulic fluid level regularly. If low, add high-quality hydraulic jack oil. Do not use brake fluid or other non-specified fluids. Refer to the manufacturer's guidelines for fluid type and capacity.
• Air System: Ensure your air supply is equipped with a filter and moisture trap to prevent contaminants and water from entering the air motor. The jack has an integrated filter, but external filtration is also beneficial.
• Rust Protection: The ram and extension screw have a rust inhibitive coating. Keep these surfaces clean and lightly oiled to maintain this protection.
• Inspection: Before each use, inspect the jack for any signs of damage, such as bent components, cracks, leaks, or loose fasteners. Pay close attention to the air hose and fittings.
• Storage: Store the jack in a clean, dry environment with the ram fully retracted to prevent corrosion and extend seal life.
