Maintenance

Preventative Maintenance

There is a grease filled secondary seal/bearing area on
each valve shaft. Every 10,000 cycles, or twice each
month, new grease should be flushed across this area.
Each valve has two flush grease fittings. A small
grease gun is provided with each valve.
To grease the valve:
1. Remove the grease fitting from one side of the
gun.
2. Pump grease (Part No. 115982) across the valve
until grease comes out of the other side.
NOTE: For valve 249591 only, use grease 117773.
3. Reinstall the outlet grease fitting.
