Series 322 Load Unit

Maintenance

5. If there is a specimen in the load unit, remove it.

The lifts contain hydraulic fluid under high pressure.

If the bleed port screw is unscrewed all the way, the screw can fly out of its

port at high velocity and it could hurt you or damage your equipment.

Unscrew the bleed port screw no more than 1/2 turn to vent the trapped air.

Open to Bleed

6. Use a 1/8 inch hex key (or slotted screwdriver, depending on model number)

to open one of the bleed ports. Do not unscrew the bleed port screw more

than 1/2 turn.

7. Briefly turn the Lift Control to the lift crosshead position to pressurize the

lift cylinders. Then return it to the stop crosshead position.

8. Shut the bleed port when bubble-free fluid begins oozing out. If necessary,

again pressurize the lift cylinders to force all the air out.

9. Repeat Step 6 through Step 8 to bleed the air out of the other lift cylinder.

Note If fluid continues to leak out of a shut bleed port, turn off hydraulic

pressure to the load unit. Let the pressure in the lift cylinders return to

zero. Then replace both bleed port screws (MTS par number

010-037-601).
