complete removal from the system or by
installation of a shut-off valve between the
gauge and the high-pressure line.
Should the hydraulic gauge be left in operation
continuously, the calibration of the gauge may
be greatly affected, requiring recalibration or
complete replacement. Shut-off valves are
recommended as added protection for any
hydraulic gauge that may be subjected to high
cycle rates or pressure fluctuations.

4.0 INSTALLATION
NOTE: When making hydraulic connections,
use high quality sealing compound only on the
threads of the male NPT fittings. If you use
Teflon tape, do not tape the first thread. Use
tape sparingly. Loose Teflon tape in your pump
or cylinder can cause malfunctions and
damage. Wrap tape so that it tightens upon
assembly (clockwise with the threads facing
you). Install your hydraulic gauge where it is
easily readable but well protected against
damage from external sources.
1. Remove the hydraulic oil outlet plug(s) from
your pump.
2. Apply sealant (or Teflon tape) to male NPT
threads. Make connections as pictured
above. When tightening hydraulic
connections and fittings, use the proper
open-end wrenches. Do not use crescent
or pipe wrenches, as they may damage the
high-pressure fittings.
5.0 OPERATION
The gauge should be operated at pressures
which do not normally exceed 75% of full
scale.
Using the gauge to read less than 10% of the
full scale can result in an erroneous reading.
IMPORTANT: The gauge should be checked
for accuracy on a periodic basis, especially
when the pressure measurement is critical and
a gauge failure or inaccuracy will create a
hazard to personnel or property.
6.0 REPAIR AND SERVICE INFORMATION
Enerpac gauges are precalibrated by the
factory to within ±1% and ±1
1/

% of the full
scale. For recalibration, please refer to your
local phone or business directory. For warranty
and/or repair service, send your gauge to the
nearest Enerpac Service Center.
6.1 Glycerin Gauge Maintenance
For maintenance, please contact your nearest
authorized Enerpac Service Center. The
procedure for filling the glycerin gauge is
covered in Enerpac's Instruction Sheet, L2561.
