6.  Operation Section 

6.1  General Safety Operating Instructions 

The following is a list of 

Do’s

 and 

Don’ts

 for the 

operation of the liftgate.

Do’s

  Read and follow warning decals, operating decals, and 

owners manual(s).

  Keep all decals in place and legible and retain the 

owners manual(s) in the vehicle or all Warranties are 

void.

   Make sure the vehicle is properly and securely braked 

before using the liftgate.

   Keep yourself clear of all moving parts.

   Make sure the area where the platform will be 

functioning (up, down, open, and close) is free of 

obstructions and people before operating the liftgate.

   Make sure the platform area, including the area in 

which loads may fall from the platform, is clear before, 

during, and at all times while operating the liftgate.

   Always place the load as close to the center of the 

platform as possible.  Also, position the load as close 

to the center of the truck’s rear sill as possible.

  Make sure the slide runners move smoothly inside the 

H-frame columns with no unusual noise or vibration.

  Only operate the liftgate with the Up/Down control 

mounted on the H-frame column or using an optional, 

inside van control.

   Follow a complete, thorough lubrication and 

maintenance schedule as directed by this manual.

   Check the oil level in the hydraulic tank monthly.  

Change the oil if it is dirty or contaminated using 

Dexron III ATF hydraulic oil or Hyken Glacial Blue.  For 

cold weather operation, we recommend Hyken Glacial 

Blue.

  Visually inspect your liftgate frequently and keep it 

properly adjusted.

  Visually inspect the platform chains and replace them if 

signs of wear or damage are present.

   Repair any damage to the liftgate to prevent accidents.

  Place the liftgate into the storage position when the 

liftgate is not in use.

Don’ts

  Do not overload the platform.  The maximum rated 

capacity is based on an evenly distributed load on the 

platform’s fl at surface.

  Do not ride on the liftgate.  Always stand clear of the 

liftgate when it is operating.

  Do not allow children to play around or operate the 

liftgate.

  Do not allow your liftgate to be used by persons not 

familiar with its operation.

  Do not crash your liftgate into loading docks or other 

objects which can infl ict serious damage to the liftgate.

  Do not use your liftgate if it shows signs of abuse or 

fails to operate freely and smoothly.

  Do not allow the motor/pump to run after the liftgate is 

fully raised and has stopped moving.

  Do not use brake fl uid in the hydraulic reservoir.

  Do not bounce the platform by pushing and releasing 

the control button/switch abruptly.

  Do not use the liftgate for anything other than its 

intended use of loading and unloading cargo. 

  Do not operate lift trucks on or over any part of the 

platform.

  Do not stand in the platform’s work area while 

operating the liftgate or place any object under the 

liftgate work area.

  Do not drive the truck unless the liftgate is in the stored 

position.
