until the pinch tube top blocks are pulled down and meet the bottom pinch tube
blocks under the thumb screws.
CAUTION: When installing new pinch tubes, ensure the pinch tube top blocks
are pulled down completely under the installation screws. Failure to tighten these
screws completely could result in improper blocking of powder, resulting in
air/abrasive release from the inactive handpiece.

Periodic Maintenance
Your Multi-Operatory Accessory requires minimal maintenance. However, Kreativ
recommends that pinch tubes and tubing are checked for wear whenever maintenance
is performed on your Mach 5/5+ system. It is also recommended that both pinch
tubes be replaced as a part of a preventive maintenance program at least once every
three (3) months.
WARNING: Failure to periodically replace the pinch tubes on the recommended
schedule could result in permanent damage to the working components of the Multi-
Operatory Accessory, rendering it unusable.
