Operation and maintenance instructions for
J
aguar
spray guns
Operation
1. Connect air supply hose at handle of gun (see page 1 for suggested gun inlet pressures)
2. The optional air control valve built into the gun handle can be used to adjust gun inlet pressure.
3. Screw the paint cup onto the guns gravity feed fluid inlet.
4. Fluid flow can be controlled using the fluid control knob, this restricts flow by
limiting needle travel. It is best to control fluid flow by proper selection of fluid orifice
size and use the fluid control knob to fine tune flow rate.
5. Fan width can be adjusted using fan control knob. Turning the knob clockwise narrow the fan.
Maintenance
IMPORTANT! Routine cleaning and maintenance is essential to insure proper gun operation.
Several states prohibit spraying solvent into the atmosphere and require the use of a covered gun
cleaner.
1. If a gun cleaner is being used, connect and clean the gun in the gun cleaner according to the
manufactures instructions.
2. If a gun cleaner is not being used:
First clean the gravity feed cup thoroughly, then spray clean solvent thru the gun until clean.
NOTE: Gun head disassembly is not recommended for
normal cleaning and maintenance.
Gun head disassembly and reassembly instructions
Gun Head Disassembly
To remove the nozzle carrier (4) and air cap adapter (5):
1. Remove the air cap (1), fluid nozzle tip (2), fluid nozzle body (3), and needle (14)
2. Remove the needle seal cartridge (15)
3. Loosen the locknut (9) and remove fluid inlet (10) using an 11/16" wrench.
4. The nozzle carrier and air cap adapter will now slide forward from
the gun handle (11).
Gun head reassembly
1. Install a new o-ring (7) on the air cap adapter
2. For model J300H only, install a new o-ring 98-8026 onto the air cap adapter
3. Install the thread locknut (9) onto the fluid inlet as far as possible.
4. Install a new seal (8) onto the fluid inlet.
5. Slide the nozzle carrier (4) into air cap adapter (5) and insert into the gun body as far as possible.
Be sure the nozzle carrier extends into the hole at the back of the gun head. Install the needle seal
(15) but do not tighten.
6. Rotate the nozzle carrier until the fluid inlet port in the nozzle carrier is aligned with the threaded
hole in the gun body. While in this position, insert the fluid inlet (10) and hand tighten firmly. DO
NOT WRENCH TIGHTEN UNTIL STEP 8.
7. Tighten the needle seal (15) to approx. 12 ft-lb. torque.
8. Tighten the fluid inlet (10) to approx. 25 ft-lb. torque.
9. Tighten the locknut (9) to approx. 33 ft-lb. torque.
