USE AND MAINTENANCE MANUAL
4.1 PRESSURE DISCHARGE PROCEDURES
When stopping the system to carry out operations on the unit or when stopping it at the end of
the working day the high pressure inside the unit must be completely discharged. When the
main air inlet is shut off, the air is automatically discharged from the pump motor.
WARNING
THE PRODUCT IN THE HIGH PRESSURE FLUID HOSE IS STILL UNDER PRESSURE.
PROCEED AS FOLLOWS:
1
Lock the trigger of the gun with the safety trigger lock.
2
Shut off the air supply to the equipment.
3
Unlock the safety trigger lock.
4
Take a metal bucket, make sure it is firmly fixed on the ground and keep the gun
pressed tightly against the walls of the bucket. Pull the trigger to discharge the product.

4.2 ROUTINE MAINTENANCE

The routine maintenance of the K90 gun is simple and does not require special operations
because its components do not need to be lubricated. Clean the gun daily or at the end of
each working session so that product residue will not dry out on its walls, thus guaranteeing
long term efficiency.
CLEANING:
Disassemble the finger protection and the tip, open the handle and thoroughly clean the filter
by means of a small brush. Check that the grip packing is not worn-out, otherwise replace it.
Carefully clean the tip, dip it in thinner to dissolve residue inside it. Blow commpressed air
throught it from the front to eliminate all traces of material. The tip must be mounted back on
with its packing. Disassemble the diffuser and thoroughly clean with a brush, in particular the
ball seat.
DO NOT USE POINTED METAL OBJECTS TO CLEAN CLOGGED ORIFICES. THESE
OPERATIONS WOULD DAMAGE THEM, REDUCING THEIR SPRAYING QUALITY.
THE LUBRICANTS USED MUST NOT CONTAIN SILICONE.
WARNING
IF THE NEED ARISES CALL THE A.O.M.- AMERICA CUSTOMER CARE TECHNICAL
SERVICE.
