PRE-OPERATION ASSEMBLY

Items Numbers reference Drawings/List on Pages 7-8

  1. Check the parts are complete, in good condition and appearance.
  2. Connect the fixed fork (30a) by bolt (32) to the safety belt (29), downward/upward bearing seat (41) separately, without loosening and ensure the safety belt is clamped firmly.
  3. Switch the power ON without load, (Buzzer may beep, switch off/on again, beep will stop.); operate the hand panel (19), platform (30) lifts smoothly up to the max. height, keep it still, and then lower it to the bottom position.
  4. Repeat step 3 with a rated load, the platform should lift smoothly to the max. height, stop without slipping, and lower smoothly to the bottom position.
  5. The maintenance-free battery, which is provided with the lifter, has been initially charged full. However the battery may require some recharging before use.

SAFETY INFORMATION (WARNINGS)

  1. Use only on smooth surfaces.
  2. Do not overload, make sure load is distributed uniformity.
  3. Buzzer will beep to alert of a low battery, charge as soon as possible or the battery can be damaged.
  4. Ensure that the input voltage of the charger complies with local power net voltage.
  5. Do not put hands/feet in contact of chain or other moving parts.
  6. Do not to carry out long hours of continuous work under extreme loads, this can lead to overheating of the motor and panel.
  7. The working life of the lift can be greatly prolonged by operating it under 0.7 times the maximum nominal load.
  8. Keep the electric control commission box closed before operation.

MAINTENANCE

Daily
Check the smoothness and stability of the platform functions, raising and lowering.
Monthly

  1. Check for any deformation, connection loosening, wearing and abnormal sounds from:
    – Connecting bolts
    – Wheels
    – Rolling bearings
    – Transmission chain
    – Pole
    – Safety belt
    – Structure parts
    – Moving parts.
  2. Check the jiggling, wearing, lubricating, and loosening of:
    – Chain
    – Sprocket wheel
    – Chain-trolley
    – Connecting bolts
    – Inner transmission box.
  3. Adequately grease parts in need.

Every 3 Months
Check the control panel, charger, battery and electric control wiring if any loosening inner transmission box and the inner box cleaning.

OPERATION

Transition/Loading/Unloading

  1. Lock casters before loading or unloading at any height.
  2. Distribute load uniformly when loading and unloading; load should not stretch over platform.
  3. Maintain control during transportation to avoid any tilting of the unit.
  4. Lower the platform to the lowest position when the loaded lifter is about to begin transportation.

Raising and Lowering the Platform

  1. Make sure adequate space is available for operation of the lifter.
  2. Lock the wheels, and switch power on.
  3. Press the UP button on the panel, the platform will climb smoothly to the needed height. Then release the button and the platform stops at its current height.
  4. Follow the instructions listed above for loading/unloading the lifter.
  5. When finished unloading at a raised height, press the DOWN button and the platform will descend smoothly. Release the Down button at any height and the platform will stop descending.
  6. The elevator is designed to with an overload protection function. Whenever the load surpasses 25% of the rated capacity, the platform will not lift; the lifter will not be able to carry out the functions of raising, lowering or unit transportation.
  7. The lifter is designed with a low power protection function. If the battery power is not sufficiently charged for operation during loaded raising/lowering, the buzzer beeps for 50 seconds continuously. Then it will cut off the power circuit automatically, with indicator light flashing. The operator will lower the platform to the lowest position during this time.

Battery

  1. High performance, maintenance-free, sealed, acidic-lead, storage battery is selected to power the lifter. It has a low discharge ability, safe, easy mounting and change-over, and can be used under the ambient temperature range of 5ºF – 122ºF (-15ºC–50ºC).
  2. The life of the battery is dependent on proper use. The working life can be greatly shortened when repeatedly using it at low voltage, and even burn the control element. The lifter is designed with a low voltage protection function in the electric controls. While the lifter is operating under low voltage while lifting/lowering, the buzzer will beep for 50 seconds continuously and then cut off the power supply. The operator will need to charge the battery as soon as possible.

Charger

  1. A high performance charger is provided with the lifter so that the battery can be charged at any handy power terminal. Be sure the voltage of the local power net is meets the needs of the inlet voltage of the charger.
  2. When charging, make sure to switch off power to the lifter, connect charger source pin and power terminal socket, the red indicator of source power of the charger is lit up, while the charging status green indicator is lit, that means the battery is in the status of charging; and when the green indicator faded, that means the battery is charged full. Generally, the charging period takes 10-12 hours.
  3. Shall the charged battery show low voltage status during heavy duty job. Probably the battery is damaged or the charger is in trouble.
