PROBLEMS
Cause Solution
• Insufficient or absent lubrication
y oil and rings. Check oil pump efficiency
• Excessive rotation speed
• Reduce rpm to the prescribed working speed
• Prolonged functioning at max vacuum rate
ough room around the pump. Verify fan conditions. C
Vacuum and/or exhaust line of insufficient diameter
• Clean inner chambers, replace vanes
• Check the secondary shutoff and filters of the suction line
due to insufficient lubrication
• Power transmission breakdown
• Check and replace the damaged 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 n
• Adjust the functioning play and lubricate
• Clean or replace if necessary
• Tank gate valves or gaskets leak
• Replace damaged or worn parts
• Tank connection pipes leak or are obstructed
• Obstructed primary shutoff or suction filter
• Vacuum line components are too small dimensioned
for pump maximum performances
• Obstructed rubber couplings
• Insufficient or absent lubrication
• Check and adjust the lubricating pump
• Before scrapping the machine, the following materials need to be
separated and suitably disposed of:
• Hydraulic oil.
• Rubber and plastic parts, such as hoses.
• Steel and aluminium parts.
• 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.
