Routine Flushing
If a complete rebuild is not required, fl ushing the
GaugeCal
XP
can serve as a quick and simple way
to remove small amounts of dirt or sediment from the system. Flushing can also be used to ensure
that any air is removed from the system prior to performing a calibration test. Flushing the unit
should never serve as a substitute for a rebuild; and remember that
any service beyond a routine
fl ush should always be performed by a qualifi ed technician.
Flushing Instructions
1
Remove all gauges from the
GaugeCal
XP
pressure comparator.
2
To completely open the reservoir, wind the handle counter-clockwise until you feel it stop.
3
Securely grip the front of the Baseplate (near the bearing block) and lift to tip the
GaugeCal
XP
on its end. Any hydraulic fl uid in the system will run out through the rear Gauge Base port.
4
Set the unit back down, fl at on the Baseplate, and begin to pour isopropyl alcohol, warm soapy
water, or clean hydraulic oil into the reservoir. Continue to fi ll the unit until the fl uid begins to
run out of the Gauge Base ports. Always dispose of fl uids in a responsible manner.
5
Once again, tip the
GaugeCal
XP
on its end until all of the fl uid in the system has drained out.
6
Set the unit back down, then wind the handle clockwise at least 10 turns, then fi ll the reservoir
with test fl uid to within 6mm (1/4") from the top.
7
Follow the operator instructions supplied with your
GaugeCal
XP
to fi ll the system and begin
calibration testing.
CAUTION:
Solvents can damage o-rings and should never be used when fl ushing or otherwise
cleaning the
GaugeCal
XP
.
