and property. Do not use near open
flame or excessive heat. Flashpoint of
solvent is 138F (59C).
Particles blown by compressed air can
be dangerous. Be certain to direct
airstream away from yourself and other
personnel in the area. Compressed air
used for cleaning will not exceed 30 psi
(207 kPa). Use only with effective chip
9-7 guarding and personal protective
equipment (goggles/shield and gloves).
1
Clean dirt and other foreign materials from flexible
shafts. Thoroughly wipe core tips with lint-free rags
saturated with dry-cleaning solvent. Wash rubber
tubing with clean water; rinse and dry.
2
Clean other parts in dry-cleaning solvent and dry with
compressed air.
c. INSPECTION
1
Inspect flexible shafts for cracking or fraying of rubber
cover and for inner damage. Check for excessive
flexibility at any point along length of tubing.
