Autoshifter Foot Pump Bill of Materials:
Hydraulic System Inspections and Maintenance:
Before putting this drum carrier into service, create a written record of the appearance and operation of the foot
pump, cylinder, and hydraulic hoses. Use the foot pump to extend the cylinder and then retract it by pressing the
release lever. Include details in your record about the amount of effort necessary to move the foot pedal as well as
how the pump and cylinder look and sound during extension and retraction. This record establishes normal condition
of the pump and cylinder. During subsequent inspections, compare observations to the written record to determine
whether the pump and cylinder are in normal condition.
Unload the drum carriage and lower the pivot arm before inspecting the pump or performing maintenance on it.
(A) Before Each Use Check For Any of the Following Conditions. Do not return the unit to service unless it is in normal
operating condition.
Oil leaks from the pump, hoses, hose fittings, etc.
Pinched or chafed hoses
