CMS TROUBLESHOOTING GUIDE
At Barreto Manufacturing we take pride in our machines and our customer service. If you are having
difficulty with your machine please call us at the number listed on the front page of this manual.
WARNING:
Always use extreme care when troubleshooting or making adjustments. Stay clear of all
moving parts or parts capable of moving while the engine is running or capable of running. The CMS
must be rendered inoperable before removing any cover. See the MAINTENANCE PREPARATION
section.
Also review: CMS OPERATORS TROUBLESHOOTING GUIDE, in the Operator’s Manual.
The CMS stalls as soon as anything is fed into either hopper.
Rotor stops, engine remains running:
The belts are too loose or worn out, replace worn out belts.
Check engine / pulley placement and belt tension.
See: section BELT INSTALLATION /REPLACEMENT
Rotor and engine stop / stall:
Make sure the engine is running at full throttle before feeding material.
Check your engine Operator’s manual and make sure the engine is up to date on all maintenance.
Old oil, dirty filters and obstructed air intakes will reduce engine performance.
Make sure that you are using fresh gasoline. Gasoline has a shelf life of about 90 days.
Check that all grease points have been greased and that bearings are in good condition.
Check that there is nothing impeding the rotors movement.
The CMS vibrates excessively:
If the vibration is coming out of the engine: See engine Operator’s manual, contact engine dealer.
Make sure that the engine is up to date on all maintenance.
If the vibration is coming from other CMS components:
Check the mulcher rotor, check for missing hammers, make sure that every hammer can swing on
the rotor pin and that nothing is stuck to the rotor.
Check the chipper disk, make sure that all looks to be in good repair and that nothing is stuck to it.
The chipping blades dulled really fast:
It is more likely that the Anvil has moved and is not in the correct position.
See section: ANVIL INSPECTION AND REPLACEMENT
If non-plant material has been fed into the chipper the blades will dull fast and may be damaged.
