Keep the gun aimed in the hopper and open the gun. Turn the pressure regulation button to
position 4 and wait until the aggregate comes out of the gun. Allow the machine to warm
up until the pump is at the required temperature and set the rotation direction button
to “Zero” or “OFF”.
10.
Turn the pressure regulation button to the 0 position and open the gun until the pressure
gauge indicates 0 bar.
11.
Now attach the required tip.
12.
Open the protective cover of the motor and position the V-belt on the centre pulley and
close the protective cover again.
13.
Push the “RESET” button and set the rotation direction switch to “1” or “ON”.
14.
Aim the gun into the hopper again and turn the pressure regulation button to a higher
position until the required spray distribution or aggregate flow is achieved.
If the pressure regulation button is turned open further but the motor
does not run faster, the maximum rpm has been reached. The pressure
regulation button may not be turned open even more because, when
the gun is closed, a very high pressure could arise, resulting in damage
to the hoses and possible injury to the operator or bystanders.
