Safety Information

WARNING: Failure to follow these safety instructions may result in serious injury or death.

• Always wear appropriate personal protective equipment (PPE), including safety shoes and gloves.
• Do not exceed the rated load capacity of 5,500 lbs (2.75 tons). Overloading can cause equipment failure and injury.
• Ensure the load is centered and stable on the forks before lifting or moving.
• Operate the pallet jack on level, stable surfaces only. Avoid inclines, declines, or uneven terrain.
• Keep hands and feet clear of moving parts, especially during lifting and lowering operations.
• Never use the pallet jack to transport personnel.
• Inspect the pallet jack for damage or wear before each use. Do not operate if damaged.
• Be aware of your surroundings and clear the path of any obstacles or personnel before moving a load.

Setup

The AFF 3900A Pallet Jack typically arrives pre-assembled or requires minimal assembly of the handle. Follow these steps for initial setup:

1. Unpacking: Carefully remove the pallet jack from its packaging. Inspect for any shipping damage.
2. Handle Assembly (if required): If the handle is not pre-attached, align the handle base with the pump mechanism and secure it using the provided pins or bolts. Refer to the assembly diagram if included with your specific unit.
3. Check Hydraulic Fluid: Verify the hydraulic fluid level. The fluid reservoir is usually located near the pump. Ensure it is at the recommended level. If low, add appropriate hydraulic fluid.
4. Bleed Air from System: If the forks do not lift or lower smoothly, there may be air in the hydraulic system. To bleed, place the control lever in the 'Lower' position and pump the handle several times.

Operating Instructions

Proper operation ensures safety and extends the life of your pallet jack.

Control Lever Positions

The control lever on the handle has three main positions:

• UP (Lift): Pull the lever fully upwards. Pumping the handle in this position will raise the forks.
• NEUTRAL (Drive): Place the lever in the middle position. This allows the forks to remain at their current height while the pallet jack can be moved.
• DOWN (Lower): Push the lever fully downwards. This will lower the forks.

Moving a Pallet

1. Positioning: Ensure the forks are fully lowered. Approach the pallet squarely, aligning the forks with the pallet openings.
2. Engaging the Pallet: Push the pallet jack forward until the forks are fully inserted into the pallet.
3. Lifting the Load: Pull the control lever to the 'UP' position. Pump the handle repeatedly until the pallet is lifted clear of the floor.
4. Moving the Load: Place the control lever in the 'NEUTRAL' position. Use the handle to pull or push the pallet jack to its destination. The polyurethane-coated steel wheels and 180-degree steering arc provide easy movement and maneuverability.

5. Lowering the Load: Once at the destination, push the control lever to the 'DOWN' position. The forks will slowly lower the pallet to the floor.
6. Disengaging the Pallet: Once the forks are fully lowered, pull the pallet jack away from the pallet.

Maintenance

Regular maintenance is crucial for the longevity and safe operation of your AFF 3900A Pallet Jack.

• Cleaning: Keep the pallet jack clean, especially the wheels and hydraulic components, to prevent dirt and debris from affecting performance.
• Lubrication: Periodically lubricate all moving parts, including pivot points, wheel bearings, and the handle mechanism, with a suitable grease or oil.
• Hydraulic Fluid: Check the hydraulic fluid level every 3-6 months, or more frequently with heavy use. Top up with high-quality hydraulic oil if necessary. German-made hydraulic seals ensure leak-free operation, but fluid levels should still be monitored.
• Wheel Inspection: Inspect the polyurethane-coated steel wheels and entry rollers for wear, damage, or debris. Replace worn wheels to ensure smooth movement.
• General Inspection: Regularly check all bolts, nuts, and fasteners for tightness. Tighten any loose components. Inspect the frame for any signs of cracks or damage.
