INSPECTION
•
All parts should be washed in a clean solvent before they are inspected and
reassembled.
WARNING
USE CLEANING FLUIDS THAT ARE NONFLAMMABLE AND AVOID
BREATHING THE FLUID VAPORS.
•
Handle all parts carefully, hardened parts may chip if dropped on a hard surface.
COLLECTION TUBE
•
Inspect the outside diameters for nicks, burrs and scoring.
•
Remove all minor irregulatities with emery cloth.
•
Check the length and I.D. size (at the chuck end) of the collection tube. The tube I.D.
should be no bigger than 1-5/8" (41 mm) and the length should be al least 37-1/2" (95
cm).
NOTE
- Due to the angle of the exhaust into the collection tube two
sides will show increased wear.
- To increase the life of the collection tube, it is important to
index the bit 90° away from the worn area of the collection
tube. This should be done after each hole.
- The wear on the collection tube is determined by a visual
inspection on the last two inches of the bit end of the
collection tube.

•
Remove all burrs on the thread with a fine file.
