4.1 Lubrication
WARNING: Any repair or servicing which requires
dismantling the pump, must be performed in a dirt-
free environment by a qualified technician.
CAUTION
: Always disconnect air supply before all
maintenance.
If the pump is operated on a continuous duty cycle for
extended periods, the manufacturer recommends an
automatic airline oiler be installed in the air inlet as
close to the pump unit as possible.
Set the unit to feed approximately 1 drop of oil per
minute into the system. Use SAE No. 10 oil.
4.2 Bleeding Air From The System
During the initial moments of activation or after
prolonged use, a significant amount of air may
accummulate within the hydraulic system. This
entrapped air may cause the cylinder to respond
slowly or behave in an unstable manner.
To remove the air, run the system through several
cycles (extending and retracting the ram) free of any
load. The head must be at a lower level than the pump
to allow air to be released through the pump reservoir.
4.3 Inspecting The Hydraulic Fluid Level
CAUTION
: Always disconnect air supply before all
maintenance.
1.
Check the oil level in the reservoir after every 10
hours of use.
2.
The oil level should come to within 1/2" of the filler
plug with all hoses attached.
3.
Drain and replenish the reservoir with an
approved, high-grade hydraulic oil such as OTC
16355 after every 300 hours of use.
Hoses:
Hydraulic hoses on this unit carry a rating
of 10,000 PSI.
Replacement hoses must carry the same rating.
45.4 Draining and Flushing the Reservoir
IMPORTANT
: Wipe the pump exterior completely
clean before attempting this procedure!
1.
Loosen and remove the six screws that fasten
the pump assembly to the reservoir. Remove the
pump assembly from the reservoir. Do not
damage the gasket, filter, or safety valve.
2.
Clean the inside of the reservoir and refill with a
suitable, non-flammable flushing oil. Rinse the
filter clean.
3.
Place the pump assembly back onto the reservoir
and secure with two of the six screws. For best
results, assemble the screws in opposite corners
of the housing.
4.
Run the unit for several minutes. Use the same
method described in Section 5-7 (Priming the
pump unit)
5.
Drain and clean the reservoir once more.
6.
Refill the reservoir with an approved, clean
hydraulic oil and replace the pump assembly
(with gasket) on the reservoir. Assemble the six
machine screws and torque 25 to 30 in. lbs.
IMPORTANT
: Drain and clean the other hydraulic
system components (hoses, cylinders, etc.) before
reconnecting them to the pump. This will prevent
contaminated oil from re-entering the pump.
4.5 Refilling The Reservoir
CAUTION
: Always disconnect air supply before all
maintenance.
1.
If additional oil must be added to the reservoir,
use only an approved high-grade hydraulic oil
such as OTC 16355 (215 SSU @ 100° F).
2.
Clean the entire area around the filler plug before
adding oil to the reservoir.
3.
Remove the filler plug and insert a clean funnel
with filter.
4.
The ram must be fully retracted and the air
supply disconnected when adding oil to the
reservoir.
