Clean bearings (49 and 56) by immersing in cleaning solvent P-D-680 and
slowly moving up and down. Remove bearings from cleaning solvent and strike
larger side of cone against a block of wood to dislodge solidified particles
of lubricant. Immerse again in cleaning solvent and repeat above until bear-
ings are clean. Dry using compressed air. Direct air stream across bearing
to avoid spinning. Dont spin bearings when drying; rotate bearings slowly
by hand to facilitate drying. After drying bearings, lubricate using clean
lubricating grease. Keep bearings in a clean area.
Clean all other parts using clean cloths moistened with cleaning solvent
P-D-680. Dry using clean cloths.
