Maintenance
Follow all safety precautions as described in the Safety
Precautions section of this manual before proceeding.
Replacing/Servicing the Seal Assembly
If your spray gun leaks or spits at the tip when you release the
trigger, the needle or seat is worn, damaged, or dirty and must
be replaced or cleaned. Refer to the Parts List section in this
manual for part identification.
Never attempt to perform maintenance on the spray gun
without first performing the “Pressure Relief Procedure.”
1. Disconnect the fluid hose from the gun.
2. Remove the tip and tip guard.
3. With the trigger depressed, remove the diffuser from the
front of the gun.
4. Remove the lock nut, rear housing, and retractor pins from
the rear of the gun head.
5. Remove the seal assembly from the front of the gun head by
pushing or gently tapping at the back of the seal assembly.
6. Soak the removed parts in the appropriate solvent and wipe
clean.
7. Inspect the parts for wear or damage and use new parts
during reassembly of the gun, when necessary.
8. Install the seal assembly into the front of the gun head.
9. Install the retractor pins into the rear of the gun head. Slide
the rear housing onto the retractor pins and secure in
position with the lock nut.
10. WIth the trigger depressed, install the diffuser into the front
of the gun head and tighten securely with a wrench.
11. Perform the “Adjusting the Seal Assembly” procedure
described below.
Adjusting the Seal Assembly
Proper adjustment of the seal assembly is essential to
ensure positive shut-off when the trigger is released.
1. Tighten the lock nut until the rear housing is flush against the
gun head.
2. Unscrew the lock nut 3/4 of a turn.
Replacing/Removing the Filter
1. Move the gun trigger lock to the unlocked position.
2. Loosen and remove the handle assembly from the gun
head.
3. Turning clockwise, unscrew the filter from the gun head.
4. Turning counterclockwise, screw the new or cleaned filter
into the gun head.
5. Make sure the handle seal is in position and thread the
handle assembly into the gun head until secure.
6. Move the gun trigger lock to the locked position.
NOTE: Left-handed threads require turning the filter
clockwise to remove.
NOTE: To check the adjustment of the seal assembly:
1. Move the gun trigger lock to the locked position.
2. Pull the trigger.
With the trigger lock engaged, there should be 1/32” of
movement between the lock nut and the rear housing
while pulling the trigger.
