Product Usage Instructions

Assembly (Model H6287/H6288)

1. Remove the cotter pin shown in Figure 2 and slide the alignment pin all the way out of the right side of the bracket.
2. Pull the chain out of the bottom of the handle.
3. While holding the handle vertically and grasping the chain, insert the handle into the bracket, align the mounting holes, then insert the alignment pin.
4. To secure the alignment pin, use a hammer to drive the tapered end of the included roll pin through the hole on the left side of the alignment pin. The roll pin should protrude an equal amount on both sides of the alignment pin.

Assembly (Model H6289)

1. Remove the four hex bolts, lock washers, and flat washers from the end of the handle.
2. While holding the handle vertically above the socket on the base, insert the stud and lock nut on the end of the chain through the hole in the center of the alignment pin.
3. Slide the handle into the socket, align the mounting holes, then secure the handle with the four hex bolts, lock washers, and flat washers.
4. Lift the foot pedal, then slide the stud and lock nut into the groove on the pedal.
   Depending upon the position of the handle lever, as shown in Figure 8, the pallet jack forks can be raised, lowered, or placed in the neutral position.

Operation

WARNING

• To reduce the risk of serious personal injury when using this machine:

  • Do not operate the pallet jack if it is damaged.
  • Never place any part of your body in the lifting mechanism, under the forks, or under a lifted load.
  • Use extreme care when handling long, high, or wide loads.
  •  Do not lift loosely stacked loads.
  • Do not exceed the maximum capacity of this jack.
  • Always balance heavy loads and move them with the forks as close to the ground as possible for maximum stability.
  • Only use this jack on hard, flat surfaces.
  •  Avoid using the jack on inclines or ramps that will cause a loss of control.
  • Never allow children to play on this jack, and never carry passengers!
  • Only operate this jack if you are strong enough to control and stop the jack when it is moving.
  • To stop the jack during an emergency, raise the handle lever and drop the load to the ground.

• Depending upon the position of the handle lever, as shown in Figure 8, the pallet jack forks can be raised, lowered, or placed in the neutral position.

• Up Position: Use to raise the pallet jack. Move the lever all the way down until it locks in place,then begin pumping the handle to raise the forks.

• Down Position: Use to lower the pallet jack. Pull the lever up slowly to begin lowering the forks. Avoid pulling the lever up quickly or you will drop the load suddenly.

• Neutral Position: Place the handle in this position when you are moving a load.

• The Model H6289 also features a foot pedal (see Figure 9) that, when pressed down, lowers the forks.

NOTICE
Damage to the pallet jack or the load may result if you drop the forks suddenly, load the forks heavier than the listed capacity, or balance a load unevenly. Lower the forks completely and remove heavy objects if the jack will be not be used for a long time.

Adjusting Fork Lowering Speed

The adjustment stud on the right side of the base (see Figure 10) can be used to control how quickly the forks lower.

To adjust the lowering speed of the forks:

1. Loosen the lock nut on the adjustment stud.

2. Turn the stud counterclockwise to lower the forks more slowly or clockwise to lower the forks more quickly.
   If you notice that the forks immediately lower a little bit after you raise them, turn the stud counterclockwise, then try raising the forks and adjust as needed until they do not sink.

3. Tighten the lock nut when you are satisfied with the adjustment.

Adding/Replacing Hydraulic Oil

Hydraulic oil in the jack cylinder may need to be added or replaced periodically after prolonged use, if it leaks out, or if it gets dirty.

To add hydraulic oil:

1. Lower the forks completely.

2. Remove the fill plug on the Model H6287-88 (see Figure 11) or the oil seal on the Model H6289 (see Figure 12).

3. Add hydraulic oil until the oil level is just below the fill hole.

4. Replace the fill plug or oil seal.

To replace hydraulic oil:

1. Follow Steps 1-2 in To Add Hydraulic Oil.
2. Remove the drain plug, let the oil drain out.Dispose the oil according to local and federal regulations.
3. Reinstall the drain plug, then add hydraulic oil until the oil level is just below the fill hole.
4.  Reinstall the fill plug or oil seal.

Lubrication

We recommend adding a few drops of SAE 10W-30 oil every three months to each rotating point shown in Figures 14 & 13.

Troubleshooting
