7. INSTRUCTIONS FOR USE

7.1 STARTING THE VIP4ToolsPro PANEL
Before using the VIP4ToolsPro panel, it is necessary to carry out some preliminary checks:
check the integrity of the equipment
-
check that the electrical and pneumatic connections have been effected correctly
-
vent the residual air from the pump using the vent screw, located at the center of the securing screws,
-
until lubricant exits (retighten the vent screw without using excessive force).
-
to facilitate the venting, regulate the pumps to maximum flow and operate for some cycles.
7.2 EXCLUDING LUBRICANT DELIVERY FROM AN INDIVIDUAL PUMP
Unscrew (anticlockwise) the red cap at the end of the pump to its stop, so completely blocking off the
delivery.
7.3 REGULATING LUBRICANT DELIVERY FLOW:
Use the red cap to determine the nominal flow of the individual pump. Completely unscrew the pump red
regulating cap (0 mm³ flow) turn clockwise for 1.5 turns (min. flow 5 mm³) after which every turn
corresponds to an increase in flow of 5 mm³ until reaching 30 mm³ at the 7
FLOW (mm³ / stroke)
0 = no pump delivery
7.4 OUTLET AIR FLOW REGULATION
Regulate the integrated brass screw at on the base mixing-manifold labelled "AIR".
By turning the screw clockwise the air flow can be closed off completely. Conversely, by turning the screw
counter-clockwise the maximum air flow can be achieved (approx 3 turns).
Do not unscrew more than 3 turns otherwise the flow regulation neddle will be dismantled from the base
7.5 ADJUSTING THE PNEUMATIC TIMER (PN. 1524845)
The illustration below shows how to adjust the frequency of lubrication cycles when using models that
contain the Pneumatic Timer.

• If inlet pressure is 8 BAR (120 PSI) reduce
the values by 8%
• If inlet pressure is 7 BAR (105 PSI) reduce
the values by 4%

• If inlet pressure is 5 BAR (75 PSI) increase
the values by 7%
