repairs are made.
1. All warning and capacity labels should be readable and complete. Wash external surfaces of unit and
decals with a mild soap solution.
2. Clean and/or remove sludge or foreign objects from the crushing chamber.
3. Remove the catch basin and clean the sludge, semi-solid waste, and foreign material. Make sure the
catch basin outlet is clear.
4. If using oil filters with paper elements, be sure to remove foreign material from catch basin to prevent
catch basin outlets from becoming clogged.
Control Valve Actuation Adjustment
Note: The setscrew on the door that actuates the control valve and the pawl on the door handle latch are
adjusted at the factory and should never need adjustment.
1. Make sure the two screws securing the control valve on the right hand side of the unit are tight. Make
sure the two screws securing the handle latch to the door are tight and the two jam nuts securing the
latch pawl to the stem are tight.
2. Loosen the jam nut securing the set screw on the door and back the setscrew out. Close door and turn
door handle fully clockwise to solidly latch the door.
3. Using a hex wrench, slowly tighten the setscrew until the top platen lowers and there is no air leakage
detected around the spool of the control valve. Tighten the setscrew 1/2 turn further and secure the
setscrew with the jam nut.
4. Rotate the latch handle 1/4 turn counter-clockwise. The air should exhaust and the ram should retract,
but the pawl should remain loosely engaged with the door closed.
5. Rotate the latch fully counter-clockwise and the door should open. Repeat steps 2 through 5 if the door
does not operate correctly.
Structural Inspection
WARNING
The jack must be removed from service and inspected for damage immediately if the jack is subjected to
an abnormal shock or load. Failure to heed this warning may result in personal and / or property
damage.
NOTICE
The owner must inspect, or appoint a knowledgeable person to inspect the jack for signs of corrosion
and / or excessive wear. Visual inspection should be made before each use of jack, checking for
abnormal conditions. Regular inspections should be made weekly for daily use and monthly for
intermittent use. Each jack must be inspected immediately if subjected to an abnormal load or shock.
Any jack which appears to be damaged in any way, is found to be badly worn, or operates abnormally
shall be removed from service until necessary repairs are made.
1. Inspect the door for closure and door handle latching operation. The door should close easily and the
door handle should loosely latch with a 90-degree rotation of the door handle. Further 90-degree rotation
of the handle should clamp the door shut and actuate the control valve. There should be the sound of air
flowing for up to 45 seconds until the ram is fully lowered and the air pressure in the ram cylinder
equalizes with the air supply.
