Power Drawbar Maintenance
Examine Air Pressure
Appropriate air supply helps with smooth actuation, and prevents premature component failure.
- Examine the air to the Power Drawbar to make sure that it's:
- Between 90 psi and 120 psi (620 kPa to 825 kPa)
- Been lubricated with common air tool oil
Lubricate the Power Drawbar
- Every 5000 cycles (or six months — whichever comes first), use
- Contact surfaces between spring washers
- Eccentric pivot mount
- Top of the drawbar (below the drawbar flange and the spring washers)
