4. Routine Service Items
4.1 Adding Fluid to Pump Reservoir
1. Check oil level.
Gravity Down Models
With the platform on
the ground, the oil level
should be within 1/2
inch of the top of the
reservoir.
Power Down Models
With the platform fully
raised, the oil level
should be within 1/2
inch of the top of the
reservoir.
1/2"
2. Add oil to fill the reservoir to the appropriate fill level.
NOTICE
To prevent damage to the pump, use only Dexron VI,
Dexron III, or Hyken Glacial Blue hydraulic fluid in the
power unit reservoir. For cold weather operation use
Hyken Glacial Blue.
If an emergency situation occurs, any anti-wear hydraulic fluid can be
used, but the system should be flushed and the fluid changed as soon as
reasonably possible. Hydraulic fluids should not be mixed due to possible
compatibility problems.
The recommended fluids are compatible and may be mixed; however, the
cold weather operating characteristics of the Hyken Glacial Blue will be
adversely affected.
DO NOT thin hydraulic fluid with brake fluid, and DO NOT use brake fluid in
place of hydraulic fluid.
3. Change the fluid if it is contaminated or dirty, or every 12 to 24 months,
depending on use.
