Troubleshooting
Specifications
Loss of Power 1. Low air pressure
2. Improper lubrication or dirt
build up
3. Worn motor parts, or other
problems
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.
