Check Blower Relief Valve
Check relief valve for proper operation every 50
hours.
To check:
1. Ensure that vacuum inlet valve and drain
valve are both closed.
2. Start engine. Vacuum will start to build.
3. When vacuum goes over relief, check for
suction at the bottom of the relief air filter.
If suction is not present, stop engine and
check relief valve.
Check Water Pressure Hoses
Check hoses every 50 hours for wear or damage.
Replace as needed.
