Note: For the VIP4TOOLS with separate controls, if you want a different cyclic setting for the various pumps, the connection

diagram must have a dedicated solenoid valve for each air inlet for the pump command.

7. OPERATING INSTRUCTIONS

7.1 STARTING UP THE VIP4Tools/Air PANEL

Before using the VIP4Tools/Air, some preliminary checks must be carried out:

check the integrity of the equipment

ensure that the electrical and pneumatic connections have been carried out correctly

Bleed the residual air from the pump, acting on the specific bleed screw located at the centre of the fixing screws until

lubricant comes out (when re-tightening the bleed screw, do not tighten excessively).

To facilitate the bleeding operation, adjust the pumps to the maximum flow rate, running a few cycles.

7.2 BY-PASSING LUBRICANT DELIVERY OF THE SINGLE PUMP:

Unscrew (anti-clockwise) the red cap located on the end of the pump until it stops, thereby completely blocking delivery.

7.3 ADJUSTING THE LUBRICANT FLOW RATE:

Act on the red cap to determine the nominal flow rate of the individual pump.

Unscrew the pump adjustment cap all the way (flow rate 0 mm³) screw in 1.5 turns (minimum flow rate 5 mm³) after

which, each turn corresponds to a flow rate increase of 5 mm³ until reaching 30 mm³ on the 7th turn. (see table)

FLOW RATE (mm³ / stroke)

0 = pump flow rate by-passed
