CAT-Xpress
PRESSURE FEED SPRAY GUN
PRODUCT INFORMATION
The CAT-Xpress spray gun oers both a pressure reduced
air cap (2403218 &2403224) and HVLP air cap (2403233 &
2403235) for areas requiring HVLP compliance.
2403218 & 2403224
- Consumes 9 cfm at 29 psi gun inlet
- Pressure reduced
- 2403218 - can be used with 0.8 mm - 1.8 mm orices
- 2403244 - can be used with 2.0 mm - 2.2 mm orices
2403233 & 2403235
- Consumes 9 cfm at 26 psi gun inlet
- For areas requiring HVLP compliance.
- 2403233 - can be used with 0.8 mm - 1.8 mm orices
- 2403235 - can be used with 2.0 mm - 2.2 mm orices

Operation and Maintenance Instructions for CAT-Xpress Spray Guns
Operation
1. Connect air supply hose at handle of gun.
2. Connect a pressurized uid supply to the gun uid inlet.
3. Fluid ow can be controlled using the uid control knob, this restricts ow by limiting needle travel. It is best to control
uid ow by proper selection of uid orice size and use the uid control knob to “ne tune ow rate”.
4. Fan width can be adjusted using the fan control knob. Turning the knob clockwise narrows 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 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:
Remove air cap and clean separately using clean solvent. For pressure setups, connect a pressurized solvent supply to the
uid inlet, trigger the gun allowing solvent to ow thru the gun until clean.
NOTE: Gun head disassembly is not recommended for normal cleaning and maintenance.
Gun head disassembly and reassembly instructions:
Have repair kit # 2411779 available before gun disassembly.
Gun head disassembly
To remove the nozzle carrier (8):
1. Remove the air cap (1 & 4), uid nozzle body (5), bae (6), uid nozzle (7), and needle (26).
2. Remove the needle seal cartridge (10).
3. Loosen the locknut (12) and remove uid inlet (13) using a 5/8”open-end wrench.
4. The nozzle carrier (8) and o-ring (9) will now slide forward from the gun body (40).
Gun head reassembly
1. Install a new o-ring (9) on the uid nozzle body carrier (8).
2. Install the thread locknut (12) onto the uid inlet (13) as far as possible.
3. Install a new uid inlet seal (11) into the recess area on the uid nozzle body carrier (8) inlet port.
4. Slide the uid nozzle body carrier (8) into the gun body (40) as far as possible. Be sure the uid nozzle body carrier (8)
extends into the hole at the back of the gun head. Install the needle seal (10) but do not tighten.
5. Rotate the uid nozzle body carrier (8) until the uid inlet port in the nozzle body carrier (8) is aligned with the threaded
hole in the gun body (40). While in this position, insert the uid inlet (13) and tighten rmly. Locknut (12) should already
be threaded onto the uid inlet (13).
6. Tighten the needle seal (10) to approx. 12 ft.-lb. torque.
7. Tighten the uid inlet (13) to approx. 25 ft.-lb. torque.
8. Tighten the locknut (12) to approx. 33 ft.-lb. torque.
9. Install bae (6) into gun body (40) with the holes facing inward towards the gun body. Make sure to line up to pins.
10. Install uid nozzle (7) into nozzle body (5), then thread and tighten into uid nozzle body carrier (8).
11. Install air cap (4) into the air cap ring (1). Sealing ring (2) and o-ring (3) should already be installed in the air cap ring (1).
then thread onto the gun body’s (40) head assembly.
Fan control disassembly
To remove the fan control (29):
1. Remove the rear uid adjustment knob assembly (36 - 39) along with the
uid needle (28).
2. Make sure the fan adjustment knob (32) is in the open position (turned
counter clockwise when pointed away from you).
3. Please note step 4 and back out the fan control sleeve (35) counter clockwise.
4. As you back out the fan control sleeve (35), the housing (31) will want to
move inward into the body. When this happens, alternate between turning
the adjustment knob (32) counter clockwise and backing out the contol
sleeve (35). Repeat until the fan control assembly fully backs out.
