21.0 RESERVOIR OIL
MAINTENANCE
The hydraulic system is fi lled with oil before shipment, and
should not require any more for proper operation.
Check the oil level after installation, and once a month after
that, by removing the venting plug on the side of the reservoir.
Fluid level should be just below the opening.
For your HD800 AC or DC hydraulic hoist system, use
Chevron Automatic Transmission Fluid, "Dexron II," or
its equivalent.
