14.2.5 Piston´s extension and retraction WP 100H
Extending the Ram
can be operated either manually or by air.
Operating by air:
Connecting the air hose (P52) of air foot valve to the
compressor. (fig 9)
Turn the handle lever (99) of socket valve to position 3.
(fig 8)
Depress the air foot valve (P54), when the piston rod is
not under load, the air motor (P23) and air motor (P35)
working together, then the piston rod extending quickly.
When the piston rod is under load, the air motor (P35)
stopping working, and only the air motor (P23) is work-
ing, then the piston rod will extend slowly.
Operating manually
Insert the handle tube (50) to the low pressure socket as process 15.2.3 (B) . then pump the
handle and extend the piston rod for quicker operation of the ram.
Insert the handle tube (50) to the high pressure socket as process 15.2.3 (A). then pump the
handle and extend the piston rod for slower operation of the ram.
The operator can extend the piston rod either by air according to process 16.1.1 or manually
according to process
Please note that when you operate by air, NEVER operate manually according to
process 16.1.2.1 (Manual Low Pressure) at the same time.
Retracting the Ram
can be operated manually or by air.
Operated by air
Connecting the air hose (P52) of air foot valve to the compressor. (fig 9)
Turn the handle lever (99) of socket valve to position 1. (fig 8)
Depress the air foot valve (54), then the air motor (23) and air motor (P35) work together, and
the piston rod returns quickly.
Operating manually:
Insert the handle tube (50) to the low pressure socket as process 15.2.3 (B) . pumping the
handle returns the piston rod quickly.
Insert the handle tube (50) to the high pressure socket as process 15.2.3 (A) . pumping the
handle returns the piston rod slowly.
The operator can retract the piston rod either by air according to process or manually according
to process
Please note that when you operate by air, NEVER operate manually according to
process (Manual Low Pressure) at the same time.
To stop the movement of the piston rod: stop pumping the handle tube (50) or release the air
foot valve (P54), the piston rod will stop moving. Then turn the handle lever (99) of selector
valve to position 2. (fig 8)
