Maintenance
Follow all safety precautions as described in the Safety
Precautions section of this manual before proceeding.
NOTE: Refer to the Parts List section in this manual for part
identification.
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.
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 from the front of the
gun.
4. Remove the reversible carbide seat from the diffuser by gently
tapping the diffuser on a hard, flat surface until the seat drops out.
5. Using a small flat-blade screwdriver, remove the gasket from the
diffuser.
6. Using a 3/16” socket wrench, remove the ball valve assembly from the
seal assembly.
7. Install the new ball valve assembly.
8. Reverse the carbide seat and place it on the ball valve assembly in the
retaining nut housing.
9. Place the gasket around the carbide seat.
10. With the trigger depressed, thread the diffuser onto the retaining nut
housing. Tighten with a wrench.
Servicing the Needle Assembly
1. Perform steps 1–6 of the “Replacing/Servicing the Seal Assembly.”
2. Loosen and remove the lock nut, rear housing, and retractor pins from
the back of the gun head.
3. Remove the seal assembly from the gun head by gently tapping on
the back of the seal assembly.
4. Soak the parts in the appropriate solvent and wipe clean.
5. Inspect the parts for wear and replace, if necessary, during reassembly.
NOTE: Lubricate all packings and moving parts before
reassembly with a lithium-based grease.
6. Reverse steps 1–3 to reassemble.
Replacing/Removing the Filter
1. Pull down on the bottom of the trigger guard and swing it away from
the handle.
2. Slide off the handle and unscrew the handle tube from the gun head.
3. Unscrew the filter from the gun head. If the filter breaks off during
removal, use a small wood screw to remove remnants from the gun
head.
NOTE: The filter has left-handed threads. Turn the filter
clockwise to remove.
4. Screw the new or cleaned filter counterclockwise into the gun head.
5. Slide the handle tube over the filter and screw it into the gun head.
6. Slide the handle over the handle tube and reattach it to the gun head.
7. Secure the trigger guard back in position on the bottom of the handle.
