  1. Emergency Shut-Off – Press to cut power to all electric control functions, preventing forks from raising and lowering.
    NOTE: This will not lock wheels in place.

  2. Battery Gauge – Indicates the voltage of the battery.
    When its voltage is low, do not use the stacker; you must charge it.

  3. Lift/Lower Lever – The control stick controls the lowering and lifting of the forks.

MAINTENANCE

  1. Daily Check and Maintenance – It is necessary to check the stacker daily. Special attention should be paid to the wheels and axles. Material may block the wheels, forks, mast and chains. They should be checked for blockage.
  2. Hydraulic Oil – Check the oil level every six months. The hydraulic oil can be ISO VG32; its viscosity should be 32cSt at 104˚F; total volume is about 4 L.
  3. Lubrication – Use motor oil or grease to lubricate all movable parts.
