GENERAL RULES - USE AND MAINTENANCE

bit LUBRICATOR

FLOW CHARTS

Use a no. 3 compass spanner to unscrew the bowl.

• Fit the lubricator as close as possible

to the point of use

• Fill the bowl with oil before pressurizing

the system

• Do not use cleaning oil, brake fluid or solvents

in general

• For correct lubrication, set the drip rate

to approximately 1 drop every 300-600 Nl

via the adjusting screw.

• Recommended lubricants:

ISO and UNI FD22

E.g. Energol HLP 22 (BP) – Spinesso 22 (Esso)

- Mobil DTE 22 (Mobil) – Tellus Oil 22 (Shell).

Flow rate

• Flow tests carried out at the Department of Mechanics, Turin Polytechnic,

using the computerized test bench following CETOP RP50R recommendations

(ISO DIS 6358-2-approved) with ISO 5167 diaphragm gauge.

(A) = 2 bar - 0.2 MPa - 29 psi

(B) = 4 bar - 0.4 MPa - 58 psi

(C) = 6 bar - 0.6 MPa - 87 psi

(D) = 8 bar - 0.8 MPa - 116 psi

(E) = 10 bar - 1 MPa - 145 psi
