CAUTIONS:



If the test fluid or gas (oxygen) will be reactive with the oil in the tester's reservoir, testing must be performed

with an instrument supplied with synthetic oil. Before hydraulic oil is replaced, the tester must be thoroughly

cleaned, and the seals should be replaced to insure proper cleaning.



Before bleeding pressure from the tester, the valve at the pressure source should be closed. The instrument's

pressure should then be slowly bled to atmosphere. If a vent valve is unavailable, the fitting at the tester should

be carefully and slowly loosened. This procedure is to create a small leak, minimizing the volume of oil that will

enter the interconnecting tubing.



Hydraulic Fluid, such as: Shock absorber, brake fluid, or transmission fluid may not be substituted for the

hydraulic oil specified for the instrument.



Never touch the cleaned piston with your bare hands. The natural dermal grease can cause a jamming of the

piston cylinder system.



Never press the piston forcibly into the cylinder. Otherwise it is damaged.



The weight should be handed with gloves. If fingerprints or other impurities are found on the weight pieces in

spite of this precaution, they can be removed with alcohol (spirit).



The hydraulic oil should be changed whenever visible contamination is present.



Waster oil must be disposed of according to legal requirements.
