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

1. ആമുഖം

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.

4. സജ്ജീകരണവും അസംബ്ലിയും

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

1. അൺപാക്ക് ചെയ്യുന്നു: പാക്കേജിംഗിൽ നിന്ന് ജാക്കും എല്ലാ ഘടകങ്ങളും ശ്രദ്ധാപൂർവ്വം നീക്കം ചെയ്യുക. ഷിപ്പിംഗ് കേടുപാടുകൾ ഉണ്ടോ എന്ന് പരിശോധിക്കുക.
2. അസംബ്ലി കൈകാര്യം ചെയ്യുക: 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. എയർ സപ്ലൈ കണക്ഷൻ: 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

സുരക്ഷിതവും ഫലപ്രദവുമായ പ്രവർത്തനത്തിനായി ഈ ഘട്ടങ്ങൾ പാലിക്കുക:

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. ജാക്ക് സ്ഥാപിക്കുക: 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. എയർ സപ്ലൈ ബന്ധിപ്പിക്കുക: 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. ലോഡ് സുരക്ഷിതമാക്കുക: 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. വിസ്തൃതമായ പ്രദേശം: Ensure the area around and under the load is clear of personnel and obstructions.
2. ചെറുതായി ഉയർത്തുക: If the load is resting on jack stands, lift the load slightly off the stands using the jack.
3. ജാക്ക് സ്റ്റാൻഡുകൾ നീക്കം ചെയ്യുക: വാഹനത്തിനടിയിൽ നിന്ന് ജാക്ക് സ്റ്റാൻഡുകൾ ശ്രദ്ധാപൂർവ്വം നീക്കം ചെയ്യുക.
4. ലോഡ് കുറയ്ക്കുക: 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. പരിപാലനം

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

• ശുചിത്വം: Keep the jack clean and free of dirt, grease, and debris. Wipe down the ram and other exposed parts after each use.
• ലൂബ്രിക്കേഷൻ: Periodically lubricate all moving parts and pivot points with a light machine oil.
• ഹൈഡ്രോളിക് ദ്രാവകം: 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.
• എയർ സിസ്റ്റം: 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.
• തുരുമ്പ് സംരക്ഷണം: The ram and extension screw have a rust inhibitive coating. Keep these surfaces clean and lightly oiled to maintain this protection.
• പരിശോധന: 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.
• സംഭരണം: Store the jack in a clean, dry environment with the ram fully retracted to prevent corrosion and extend seal life.
