MAINTENANCE & SERVICE:
REFERENCE PARTS DIAGRAM
The maintenance is simple and will keep your regulator performing at an optimal level.
The majority pressure issues will be due to a worn or dirty piston o-ring #4 or by debris on the
pressure adjustment slug #11 seal.
WARNING: SAFETY FIRST
•
ALWAYS WEAR SAFETLY GLASSES WHEN SERVICING THE LPR OR ANY GAS
SOURCE
•
ALWAYS REMOVE THE REGULATOR FROM THE AIR SORCE AND DEGASS THE
REGULATORPRIOR TO SERVICING!
•
TO DEGASS THE REGULATOR, REMOVE THE LINE FROM THE AIR SHIFTER AND TURN
OFF THE BOTLE ACTUATOR AND PUSH THE SHIFT BUTTON UNTIL NO AIR IS

DISASSEMBLY:
1. Remove, turn counter clockwise, the gas distribution cap #2. No tools required.
2. Remove the tournament cap #13. If the tournament cap cannot be removed by hand the holes on
the tournament cap can aid in removal simply use the 3/16” allen wrench or slim screwdriver and
slide the tool through the holes and turn counter clockwise.
3. Remove the brass adjusting slug by turning counter clockwise.
4. To simplify piston removal use the supplied 1/2-20 bolt.
5. From the distribution cap end Screw the bolt into the top of the piston. Hold the regulator body #8
with the tournament cap end up. See Figure 3.
6. Note the position and location of the piston this will help at time of reassembly.
7. Slowly pull the piston out.
a. Note: If the Belleville springs should fall from the piston the correct orientation is noted on
the parts diagram. The Belleville springs have a slight curve and must be installed on the
piston correctly or the LPR will not regulate correctly.
8. Inspect the piston o-ring for damage. If there is damage replace the o-ring with the piston o-ring
included with the regulator rebuild kit.
9. Lubricate the piston o-ring with any Silicone based, non-petroleum Lubricant.
10. Inspect the regulator piston and adjusting slug seat for debris. Clean with a cotton swab and
rubbing alcohol.
