CARE OF TESTER
Unscrew and remove operating handle. Take care to avoid moving the washer and
bearing below. Grease surfaces and threads before re-assembly. Some Testers
have a removable gauge connected via a hydraulic coupler. Frequent removal and
reconnection to the guage will cause the oil reservoir level to drop and will eventually
GB
affect the amount of oil available to operate the guage. When this occurs, the oil piston
between the operating handle and the black tester body will have retracted within the
body.
TO FILL THE TESTER WITH OIL
(Model with removable gauge pre September 2011 only)
Clamp the Tester in a vice with the oil coupler in the vertical position. Connect the oil
bottle containing light hydraulic oil to the coupler on the Tester. Force any air out of
the system by pushing the piston in fully. Pull on the turning handle until the front of
the stainless piston is 10mm from the end of the body. Push this piston back in fully,
using thumbs, pull out again and repeat until all air bubbles are expelled into the oil
bottle. The piston should be set 10mm from the face of the body to give maximum oil
capacity. Remove oil bottle to complete filling operation.
A TESTER WITH A FIXED GUAGE CANNOT BE FILLED WITH OIL BY THE OPERATOR.
Recommended oil: Light mineral type DTE.
