Never attempt to perform maintenance on the spray gun
without first performing the “Pressure Relief Procedure.”

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.
NOTE: Lubricate all packings and moving parts before reassembly
with a lithium-based grease.
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.

movement between the lock nut and the rear housing while
pulling the trigger.
