HYDRAULIC DRIVE SYSTEM
WARNING! Before performing any maintenance, make sure
the Main Power Switch is OFF and incoming power is locked
OFF. The Hydraulic Unit is a component that works under
pressure. Do not open any connection or carry out
maintenance on components subject to pressure until all
press has been bled to zero.
The hydraulic unit should be serviced yearly:
1. Completely drain the Tank of hydraulic fluid.
2. Clean the Tank Top to prevent foreign material from falling into the Tank when the Lid is
removed.
3. Unscrew the Suction Pipe from its connection with the Hydraulic Pump.
4. Remove the Lid and Suction Pipe from the Hydraulic Tank. Take care not to damage
Tank Lid Gasket.
5. Inspect the bottom of the Tank for sediment and clean as required. Clean the Suction
Pipe and its connections.
6. Insert the Suction Pipe into the Tank and replace the Lid. Again, take care not to
damage Tank Lid Gasket. Connect the Suction Pipe securely to the Hydraulic Pump
using thread sealant.
7. Fill the Tank with 20 gallons (76 Liters) of approved hydraulic fluid. See page 56 for
recommendations.
8. Ensure the Hydraulic Pump Case is full of fluid (Installation, page 13) and proceed with
the normal operation.
