HIGH AND LOW SPEED HANDPIECE STERILIZATION PROCEDURES:
(AUTOCLAVE AND CHEMICLAVE ONLY)
Clean external surface: Remove bur from handpiece and scrub with a toothbrush or 2” x 2” gauze
using warm tap water. DO NOT IMMERSE HANDPIECE.
Dry: Thoroughly dry handpiece using gauze, paper towel or air syringe.
Clean / lubricate: Using a combination cleaner / lubricant, spray into handpiece drive air hole and in
chuck.
Expel cleaner / lubricant: Reinsert bur into handpiece head, connect handpiece to tubing and run for a
few seconds to thoroughly expel debris and excess lubricant.
Bag and cycle in autoclave: Place handpiece into autoclave bag or pouch. Cycle as per autoclave /
chemiclave manufacturer’s instructions. DO NOT EXCEED 275° F (135° C).
Cool down and lubricate: Allow handpiece to return to room temperature. Lubricate handpiece as per
instructions listed above. Expel excess lubricant as per previous instructions. Wipe down handpiece.
DO
Use warm tap water to scrub the exterior of handpiece.
Expel excess lubricant from handpiece by running it for a few seconds after cleaning and lubricating.
Use separate cans of lubricant before and after sterilization to prevent cross contamination.
Use autoclave bags and pouches with indicators to protect handpiece.
DON’T
DON’T immerse handpiece in water or chemical disinfectant / sterilizer
DON’T use any type of disinfectant on handpiece.
DON’T sterilize handpiece with bur inserted.
DON’T exceed 275° F (135° C) in autoclave or chemiclave.
DON’T dry heat or heat transfer sterilize.
DON’T operate handpiece without bur or bur blank inserted in chuck.
TROUBLESHOOTING COMMON HIGH SPEED HANDPIECE ISSUES
A. Handpiece sluggish (could be lack of lubrication or too much debris)
1. Try heavily spraying “correct” drive air tube with a combination cleaner / lubricant #10083
available from Engler Engineering Corporation and run handpiece for a minute.
B. Burs are sticking inside of turbine or falling out
1. Flush the chuck / spindle with a handpiece cleaner.
2. Ensure that burs are not worn or scored, less than .0625” or larger than .0630” which can
damage spindle.
C. Water spray is weak or completely stopped
1. Insert water port cleaning tool item # 10541 into water tube from head of handpiece to
remove debris.
2. Use our Smart Cleaner to clear clogged tube.
If these simple solutions fail, more serious problems are likely affecting the handpiece, which should
be sent to the manufacturer if under warranty or Engler Engineering Corporation if warranty has
expired.
