to direct any oil that escapes during the bleeding
process into a container.

Unload the deck.

Rotate the maintenance prop into position. See diagram in INSPECTIONS AND MAINTENANCE (DC UNITS)
section on p. 10 (below).

Press the DOWN button until the deck is entirely supported by the maintenance prop.

Locate the bleeder valve located at the top of the cylinder. It looks like a grease zerk and is identified in the
BLEEDING AIR FROM HYDRAULIC SYSTEM (DC UNITS) on page 9. Hold a rag over the valve. Turn the hex
head with a wrench until air begins to escape (about a half turn). Oil and air will sputter from the valve.

Jog the motor a few times by briefly pressing and releasing the UP button. If air continues to escape from the
bleeder valve, jog the motor several more times. Wait 5-10 seconds between jogs.

Close the valve once air no longer is seen in it or heard bubbling out of it. A clear stream of oil, i.e. without
bubbles, should be seen flowing from the valve.

Remove the cover from the modular power unit. Perform the inspections and maintenance described in the
MPU-DC manual. For instance, check the oil level in the reservoir. If the surface of the oil is lower than 1 to 1½
in. below the fill port, then add oil. Use anti-wear hydraulic fluid with a viscosity grade of 150 SUS at 100°F
(ISO 32 @ 40°C) like AW-32 or Dexron transmission fluid.
RECORD OF SATISFACTORY CONDITION (DC UNITS)
Before putting the cart into regular service, make a record of its appearance and operation. Photograph the
cart from multiple angles. Include close range photographs of pivot points and pivot point hardware, deck rollers,
labels, casters, and the maintenance prop. Cycle the deck up and down. Describe the motion of the legs and
rollers. Describe the sound of the power unit as it operates. Also include a description of the cylinders as they
extend and retract. Each cylinder should extend and retract smoothly. The cylinders should extend/retract at the
same rate. Collect all photographs and writings in a file. The file is a record of the cart in satisfactory condition.
Compare inspection results to this RECORD to determine if all components of the cart are in satisfactory
condition. DO NOT use the cart unless it is in satisfactory condition.
INSPECTIONS AND MAINTENANCE (DC UNITS)
NOTE: Inspect and maintain the modular power unit as directed in the supplementary MPU-DC MANUAL .
Inspections and repairs should only be performed by qualified persons. Compare the results of each inspection
to the RECORD OF SATISFACTORY CONDITION (DC UNITS) . Do not use the cart unless it is in satisfactory
condition. Replace parts that are not in satisfactory condition before returning the cart to service. DON’T GUESS!
If you have any questions about the condition of your cart, contact the
TECHNICAL SERVICE
department.
The phone number is provided on the cover page of this manual. Never make temporary repairs of damaged or
missing parts . Only use manufacturer-approved replacement parts.
Immobilize the deck with the maintenance prop before
inspecting, or performing maintenance on, the cart.
1. Unload the cart.
2. Raise the deck to its maximum height.
3. Deploy the maintenance prop by pivoting the free
end into contact with the frame (dotted arrow).
4. Lower the deck until the maintenance prop
presses against the end of the frame.
(A) Before each use, check the cart for any of the following
conditions. Correct all problems.

Oil leaks;

Pinched or chafed hoses;


in. below the top of the reservoir/tank
with the deck fully lowered. See MPU-DC manual. Check for oil leaks. Resolve the
issue as described in TROUBLESHOOTING on 12-13. Add oil, if necessary.

Check the hydraulic hoses for wear, kinks, cuts, etc. Replace damaged hoses.

Check hardware: roller bushings, axle pins and retaining rings, clevises, pivot points, fasteners, and casters
for severe wear and damage. Replace all components that are severely worn or damaged.

Inspect each leg roller for looseness, cracks, uneven or severe wear. Replace rollers as necessary.

Cycle the deck. Listen for unusual noises; watch for abnormal movement. See TROUBLESHOOTING .

Make sure all labels are in place & in readable condition. See LABELING DIAGRAMS on p. 13.
