use only in a well ventilated
area. Avoid contact with skin, eyes and clothes and don’t breathe
vapors. Do not use near open flame or excessive heat and don’t smoke
when using it. Failure to do so could cause serious injury. If you be-
come dizzy while using cleaning solvent, get fresh air and medical
attention immediately. If contact with skin or clothes is made, flush
with large amounts of water. If contact with eyes is made, wash eyes
with water and get medical aid immediately.
Compressed air used for cleaning purpose will not exceed 30 psi. Use
only with effective chip guarding and personal protective equipment
(goggles/shield, gloves, etc). Failure to do so could cause serious
injury to eyes and possible blindness. If you hurt your eyes or if a
foreign object is blown into your eyes,
seek medical attention
immediately.
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. Don’t 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.
