6.

Adjust the PR 3E (or PR5) paint pressure regulator as required (from 0 to 3,0 bar for PR3 E, and

from 0 to 6.0 bar for PR5).

7.

Adjust the spraying air by means of the reducer (Pos. F on page 30) and test the gun on a panel
before using it.

PRECAUTIONS

a)

Use the gun under pressure.

b)

When the paint level inside the tank decreases, the pump can suck some air. Increase 
the paint level.

c)

Do not drag the pump by pulling it by the pipes.

PRECAUTIONS: EMERGENCY STOP

When the pump must be stopped because of the following reasons:

a)

The material does not stop coming out of the gun.

b)

Fluid discharge through the connectors or the damaged pipe. CLOSE THE THREE-WAY 

VALVE
