Replacing/Servicing the Seal Assembly
If your spray gun leaks or spits at the tip when you release the trigger, the

Never attempt to perform maintenance on the spray gun
without first performing the “Pressure Relief Procedure.”
1. Disconnect the spray hose from the gun.
2. Remove the tip and tip guard.
3. With the trigger depressed, remove the diffuser and the copper
washer from the front of the gun housing.
4. Remove the head screw, trigger pivot screw, and trigger.
5. Remove the plug from the rear of the gun housing.
6. Insert the repair tool into the passage at the rear of the gun housing,
and force the seal assembly out through the front of the gun.
NOTE: If a repair tool is not available, remove one of the screws
from the bottom of the gun handle and use it to tap on the
back of the seal assembly.
7. Lubricate the o-rings on the new seal assembly.
8. Install the new seal assembly into the front of the gun housing. Using
the open end of the repair tool, force the seal assembly completely
into the gun housing. Push on the ball at the front of the seal
assembly to ensure complete insertion.

housing up to the seal assembly.
