Crushing Hazard. Ensure that the engine start switch is in the OFF position, and that the parking brake is engaged before entering the articulation area. Failure to do so could result in serious injury or death.
Check that the lines attached to all the remote grease fittings are undamaged. If the grease lines are split, grease will not reach the components that require lubricating. Machine damage will result.
Inspect the drive shaft universal joints for wear, loose bolts, or missing bolts. Tighten loose bolts and replace missing bolts. Inspect the drive shaft splines and bearings for wear. Replace worn components.Wipe off the fittings before any lubricant is applied.
