2. COMMISSIONING
• With the pump on a level surface
the shipping plug should be
removed from the filler breather
port on the pump and the oil level
checked. The oil level should be
20mm (3/4”) below the pump lid if
it is low top the level up with Boss
Hydraulic oil .Then fit the filler
breather.
• The pump can now be connected
to a cylinder ensuring all
couplings are fully engaged. For
the first operation the cylinder
should be positioned below the
level of the oil in the pump.
• The airline can now be connected
to the pump.
• For single acting PA010 and
PA019 pumps depress the end
of the foot pedal end marked
“PUMP” the pump will operate
and the cylinder will extent.
To release the pressure in the
system and retract the cylinder,
depress the end of the foot pedal
marked “RELEASE”.
• For double acting PAD019 pumps
which have a 3 position valve the
hose connected to “A” port on the
valve should be connected to the
bottom or cap end of the cylinder.
•
The hose connected to “B” port
on the valve is the connected to
the top or rod end on the cylinder.
With the valve handle in position 1
depress the end of the foot pedal
closest to the air inlet and the
cylinder will extend.
3. OPERATION
• Prior to each use the pump,
hoses and any gauges and
accessories should be visually
inspected and any damaged
components replaced.
• The oil level should be checked
regularly and when necessary
toped up with Boss Hydraulic oil.
• Do not attempt to connecting
unretracted cylinders as they can
cause the reservoir to overflow.
• The pump output pressure can
be controlled by adjusting the
input air pressure with an air
pressure regulator however a
hydraulic pressure regulator
fitted to the pump output is a
better option.
• To retract the cylinder place the
valve handle in position 3 and
depress the foot pedal. Placing
the valve handle in position 2
will block “A” and “B” ports and
depressing the foot pedal will
circulate oil back to the reservoir.
• For both single acting and double
acting pumps they should be
operated through 3 or 4 cycles
initially to remove any air from
the system.
