PROBLEMS
Cause Solution
• Insufficient or absent lubrication
• Verify oil and rings. Check oil pump efficiency
• Low tank oil level
• Fill tank with oil
• Excessive rotation speed
• Reduce rpm to the prescribed working speed
• Prolonged functioning at max vacuum rate
• Reduc
e vacuum rate
• Insufficient cooling
•
Check oil pump efficiency
.
Bleed the system with care
.
Check heat exchanger
efficiency
•
Vacuum and/or exhaust line of insufficient diameter
•
Check dimensioning
Cause Solution
• Br
oken vanes:
• Clean inner chambers, replace vanes
-
due to infiltrated solids
• Check the secondary shutoff and filters of the suction line
-
due to insufficient lubrication
• Check the oil pump
• Power transmission breakdown
• Check and replace the dam
aged parts
• Ice inside the pump (during the cold season)
• Remove ice and slowly start running it. Avoid suction of water
Cause Solution
• Four way changeover valve in idle position
• Move the lever to vacuum or pressure
mode end stroke
• Four way changeover valve not correctly registered
• Adjust the functioning play and lubricate
• Worn vanes
• Replace vanes
• The non
-
return valve leaks
• Clean or replace if necessary
• Worn seal rings
• Replace
• Tank gate valves o
r gaskets leak
• Replace damaged or worn parts
• Tank connection pipes leak or are obstructed
• Replace damaged pipes
• Obstructed primary shutoff or suction filter
• Remove and clean
• Encrusted exhaust port
• Remove and clean
• Vacuum line components
are too small dimensioned
• Verify dimensions for pump maximum performances
• Obstructed rubber couplings
• Replace
Cause Solution
• Insufficient or absent lubrication
• Check and adjust the lubricating pump
• Recycling materials allow reducing the environmental impact and
respecting the environment.
Do not dispose of in the environment. Dispose of
in compliance with the standards in force.
• Before scrapping the machine, the following materials need to be
separated and suitably disposed of:
