Valve Adjustment Procedure
NOTE: All Poweramp EH leveler's are factory
tested and should not require additional
adjustments in the field. Consult the factory if
minor adjustments do not result in proper
operation.
Whenever valve adjustments are made, note
the number of turns made to allow an
undesirable adjustment result to be reversed.
CAUTION: Do not adjust relief valve (RV1) this
valve is preset has a security lock to prevent
adjustment. If security wire is cut warranty me
be void.
When service under the dock leveler is required,
always lock all electrical disconnects in the OFF
position after raising the platform and engaging the
maintenance prop. Failure to do this may result in
serious personal injury or death.
Always post safety warnings and barricade the
work area at dock level and ground level to prevent
unauthorized use of the dock leveler before
maintenance is complete. Failure to do this may
result in serious personal injury or death.
Always stand clear of the dock leveler lip when
working in front of the dock leveler.
The maintenance prop MUST be in the service
position when working under the dock leveler. For
maximum protection, use an OSHA approved
locking device to lock the maintenance prop in the
service position. Only the person servicing the
equipment should have the key to unlock the
maintenance prop.
Unless the dock leveler is equipped with a tethered
remote, two people are required to engage the
maintenance prop: one person to operate the unit,
the other person to engage the maintenance prop.
Failure to follow these instructions may result in
serious personal injury or death.
