well-ventilated areas. Keep away from open flames and other sources of ignition.
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure
when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when cleaning compo-
nents. DO NOT direct compressed air against human skin. Failure to follow this warning may cause
injury or death. Make sure air stream is directed away from user and other personnel in the area. To pre-

INSTALLATION
CAUTION
To obtain correct bolt torque on ground engaging tools, use the following steps:
Clean all surfaces, including recesses; remove all rust, paint, nicks and burrs.
Assemble the component and apply specified torque to fasteners. On components that require more than
