Turn on the electrical source, unlock the electric door lock, and move the stacker near the shelf or
rack (keep the front of the fork at a minimum of 12 inches from the goods shelf or rack). Press the
lowering button, adjusting the height of the forks to a proper position, and insert the forks slowly
and as deeply as possible into the pallet. Press the lifting button until the fork is at a minimum of 4
inches from the shelf or rack. Slowly drive the stacker and slowly move the goods out of the shelf
or rack (keep the front of the forks at a minimum of 12 inches from the goods shelf or rack). Press
the lowering button and lower the forks to a height of 8-12 inches from the ground. Move the
stacker away from the shelf and drive it to the desired position and then stop slowly. Press the
lowering button to lower the load and back out the forks completely from the pallet.
After Each Use
When the stacker is not in use, store it in a secure place out of the reach of children. Inspect it for
proper working condition prior to storage and before re-use.
Maintenance
Maintain the Stacker: It is recommended that the general condition of any tool be examined
before each use. Keep your stacker in good repair by adopting a program of conscientious repair
and maintenance. If any abnormal vibrations or noise occurs, have the problem corrected before
further use. Have necessary repairs made by qualified service personnel.
Routine Maintenance: Routine maintenance for the stacker consists of cleaning it regularly,
keeping the batteries clean and charged, and examining any cords, hoses, or moving parts
regularly for wear or potential damage. Never operate with damaged parts. Always repair any
damage to the stacker before using or operating it at any time.
Maintenance for Mechanical System/Parts: Perform at least every six months. Add lubricant to
the bearings of the drive wheel and the doorframe. Examine fittings and connections to be sure
they are fully tightened. Check the flexibility and condition of wheels, and the door-frame rollers.
Check that the lifting range of the forks is operating normally. The operation noise level of the
stacker should be no more than 70dB.
Maintenance for Hydraulic System/Parts: Perform at least every six months. Check the oil
cylinder for any leakage externally or internally. Check all the hydraulic hose connections for any
leakage. The hydraulic oil should be kept clean and generally should be replaced every 12
months. Only ISO hydraulic oil should be used. For higher temperature conditions, HL-N46 or HL-
N68 should be used; for lower temperature conditions, HV-N46 or HV-N68 hydraulic oil. Old
hydraulic oil should be treated according to any local rules and regulations.
Maintenance for Electric Equipment/ Batteries: Perform at least every three months. ALWAYS
wear safety goggles and rubber gloves when working with batteries. Every 3 to 6 months, check
the level of the water in the batteries (only when using no-seal batteries). Remove the battery cap
and check if the water level is below the fill line. ONLY use distilled water, if any is needed.
Securely replace the battery caps and begin charging and using as normal.
Check to make sure that the battery terminals are clean. Terminals should be kept clean with
Vaseline and tightened. Examine any of the connections of the electrical devices or switches,
making sure they are tight and operating properly without sign of wear to wires.
