1. Check air supply. For rated
performance, 90 PSI air
pressure is required at the
tool, with tool operating
2. Check for wet or dirty air.
Wet air tends to wash
lubricant away. Dirt or
foreign matter will impede
the action of the motor. If
dirt or water has entered the
tool, flush with John Deere
AT-4003.
3. Contact your customer
service.
1. Low air pressure
2. Improper lubrication or
