Troubleshooting Guide

Problems Required actions
The engine does not work
  • Check the DC motor connection and switch ;
  • Check the cable that connects the motor terminal to the starter solenoid ;
  • Check the remote control.
Lack of speed or increasing pressure
  • Adjust the safety valve HYRV08 ;
  • Loose the lock nut ;
  • Screw up the Allen bolt to his maximum, then screw down 1 ½ turn ;
  • Screw up the lock nut ;
  • Do a check up on the down screw, need to be close (clockwise), where it is located on the solenoid HYSV082.

The starter solenoid engages, but the engine does not active
  • Check if the wires are in place on the terminals ;
  • Check that the correct wire diameter has been used to connect the motor ;
  • Check if the solenoid starter housing is cracked. If yes, replace the solenoid ;
  • If the unit is older, visually check for accumulation of excessive rust.
The unit lowers too slowly
  • Unscrew the adjustment nut 1/4″ maximum (#HYSV082).
The electric motor does not stop working even if you release the button
  • The starter solenoid does not stop
    A weak battery or poor grounding may have soldered the starter solenoid. Replace it and check the condition of the battery and the connection wiring.
Excessive heat of the unit
  • Low battery or bad grounding
    Improper grounding connection or low battery may cause the engine to operate at a high temperature. Check the condition of the battery and the connection wiring. Don't operate the unit too long. If excessive heat persists, return for verification.
  • Safety valve remains open
    If the relief valve isn't properly adjusted or if debris has settled inside and remains open, this will generate a lot of heat in the oil. Remove the valve. Clean with brake cleaner or Varsol. Dry with pressurized air and replace the check valve (couple at 22 Nm). Restart the unit and adjust the valve to the system safety pressure (see sticker on the tank).
Pressure problem
  • Locate the manual bypass of the solenoid valve. Rotate counter-clockwise to the end. The valve is now closed and should operate normally (#HYSV082).

IMPORTANT
For the model HYP6GDD equipped with HYD033C6 valve, the battery must always be full load, because it must have a minimum of 11 volts to activate the valve which will proceed to the descent. Activate the valve manually at the end of the drawer.
