3.0
The F1000 has two parts of the mechanical system that can be serviced by the user.
The first is the air pressure and flow system. This system operates the mechanical
movement of the gun, and involves the following parts:
The handle, trigger, cylinder and piston assembly, and the air injection system.
Prior to performing any service work on the air pressure and flow system of
the F1000, be sure that the air hose to the dispenser is disconnected.
The second system of the F1000 that can be serviced by the user is the chemical
flow system, and involves the following parts:
The mix cartridge, the carrier, the on/off valves for the "A" and "B" chemicals, hose
connections and check valve assembly, and replaceable O rings and filters.
Prior to performing any service work on the chemical flow system of the
F1000, be sure that all chemical pressure on the hoses and in the gun has
been relieved. The procedure to relieve the pressure on the hoses is de-
scribed in the section of this manual that covers maintenance and service
of the chemical flow system.
The Air Injection System is comprised of two valves, an On/Off Valve (D704) and
a Needle Valve (D703) that are connected to the F1000 by a series of simple
1/8" fittings.
(See diagram 23A)(See diagram 23A)
(See diagram 23A)(See diagram 23A)
(See diagram 23A) The Air Injection System serves three pur-
poses:
* The air flowing into the Mix Cartridge (D603) helps the mixing of the “A” and
“B” chemicals.
* The air flowing into the Mix Cartridge (D603) helps propel the chemicals out
of the nozzle, and also helps to keep the nozzle clear of curing foam.
The Needle Valve (D703) can be adjusted by turning the knob to control the
amount of air flowing through the system. Different uses of the F1000, for
example spraying foam, may require a higher flow of air than pouring foam.
Experience in using the F1000 will help the user determine what air flow level
suits their needs.
The Air Injection System should require no routine maintenance. The two valves
can be replaced if they should wear out. Care should be taken to keep the Air
Injection System free of obstructions. Triggering the F1000 without removing
the Mix Cartridge Plug (D620) can cause foam to back flow into the Air Injec-
tion System, which will block it. In this situation the two Valves (D703, D704),
and associated air fittings have to be replaced. Extreme cases of this backflow
have caused foam to flow back through the Air Injection System, and into other
components of the F1000.
