OPERATION (con't)
9. Stabilize workpiece in a manner which will not allow it to inadvertently fall from the bed once the load is removed,
then turn release valve counter-clockwise to retract the ram and remove workpiece. Do not turn the release valve
counter-clockwise more a 1 full turn.
For Models 60120 & 60200 Only: Use only handle provided by manufacturer. The handle provided with
!
this product will safely engage the release valve of bottle jack and operate the handle sleeve. If handle is
worn, operates abnormally, or will not positively engage the release valve, STOP, discontinue use of the jack until
a factory replacement handle and be qcquired.
For Models 60120 & 60200 Only: Unlike presses equipped with a separately mounted pump, the power
!
unit on this press can not be equipped with a pressure gauge, therefore monitoring the load must be done
by other means, such as a load cell w/digital indicator. Whatever means is chosen, the load measuring means shall
be calibrated annually.
The hydraulic power unit provided with this device is intended to be used as an integral part of this press
!
and not as a stand-alone jacking device separate of the press. Never use the hydraulic power unit provided
with this press for any purpose other than that for which it is intended.
MAINTENANCE
Before each use, inspect press for damage. Do not use if bent, broken, cracked, leaking or otherwise damaged
components are noted. Periodically, lightly oil all moving parts, including the pump piston and ram.
For Models 60120 & 60200:
Adding/Changing oil to bottle jack
Important: Use only good grade hydraulic jack oil. Avoid mixing different types of fluid and NEVER use brake fluid,
turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause premature failure of the jack and the
potential for sudden and immediate loss of load. Premium hydraulic jack oil or equivalent recommended.
1. Remove jack from press frame.
2. With ram fully lowered and pump piston fully depressed, set jack in its upright, level position. Remove oil filler plug.
3. Drain used fluid into a suitable container
Note: Dispose of hydraulic oil in accordance with local regulations.
4. Fill until oil is level with or just below filler plug hole.
5. Perform Bleeding/Venting Trapped Air procedure.
For Models 60123, 60253 & 65123 Only:
Adding/Changing oil to hand pump
Important: Use only premium grade hydraulic oil. Avoid mixing different types of fluid and NEVER use brake fluid,
turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause premature failure of the ram and pump
and the potential for sudden and immediate loss of load. Premium hydraulic jack oil or equivalent recommended.
For best results, change fluid once a year.
1. Depressurize and disconnect hydraulic hose from application.
2. Remove oil filler screw located on top of the reservoir.
3. Pour used fluid into a sealable container.
Note: Dispose of hydraulic fluid in accordance with local regulations.
4. With pump in its upright, horizontal position, use a small funnel to fill reservoir to within 1/4" (6 mm) of the opening.
5. Wipe up any spilled fluid and reinstall the vented oil filler plug.
6. Perform Bleeding/Venting Trapped Air procedure.
Bleeding/Venting Trapped Air procedure:
1. Place pump at a higher elevation than the hose and ram as
shown in figure 7.
2. Operate pump to fully extend and retract the ram 2 or 3 times.
The objective is to force the air bubbles up hill and back to the
pump reservoir.
3. To bleed the air from pump reservoir, simply open the oil filler
screw. Re-install after bleeding.
