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 pressure 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
Cover is removed.
3. Unscrew the Suction Pipe from its connection with the Hydraulic Pump.
4. Remove the Cover and Suction Pipe from the Hydraulic Tank. Take care not to
damage Tank Cover Gasket.
5. Inspect the bottom of the Tank for sediment and clean as required. Clean the Suction
Pipe and its connections
6. Fill the Tank with 12 gal (45 L) of approved hydraulic fluid. See page 51 for
recommendations.
7. Insert the Suction Pipe into the Tank Cover and install the Cover. Again, take care not
to damage Tank Cover Gasket. Connect the Suction Pipe securely to the Hydraulic
Pump.
8. Ensure the Hydraulic Pump Case is full of fluid and proceed with the normal operation.
