FOREDOM Handpiece H.20 Manuals

Shaft and Sheath Adjustment for Handpiece H.20 and H.20D It is important to check the sheath and shaft tip and properly adjust them before you attach this handpiece to your Foredom flexible shaft tool. The tip of the flexible shaft should extend 3/4″ beyond the end of the sheath and no more than 7/8″ or less than 5/8″ (see above). On Foredom machines with standard shaft and sheath, this adjustment is made by loosening the set screw in the motor connector and moving the sheath in or out while the motor and shaft/sheath assembly are fully extended and straight while hanging or on a flat surface. When the adjustment is correct, tighten the set screw in the motor connector. Attaching the Handpiece to the Flexible Shaft Attach the handpiece by pushing it on the grooved QD (quick disconnect) fitting on the sheath. Be sure that the keyed tip of the flexible shaft is properly lined up with the slot in the handpiece shaft connector by looking into the rear of the handpiece before pushing it on. If it is not in line, turn the handpiece to the correct position. IMPORTANT INSTRUCTIONS For Handpiece H.20 and H.20D • Keep a 2.35mm (3/32″) shank in the handpiece at all times, during operation and storage. • Never turn collet release lever while flexible shaft is rotating. The release lever is not intended for use as a brake. For More Information For more information on Foredom machines, handpieces, or accessories, contact your local dealer.

Flexible Shaft Cleaning and Lubrication should be performed every 50 hours of use: Unscrew motor connector (left hand thread) and remove drive shaft. The flexible shaft should be thoroughly cleaned with a solvent. Apply a light film of Foredom grease (p/n MS10006) to entire length of inner shaft. Reconnect shaft (see shaft and sheath adjustment instructions on reverse) and sheath and run motor for a ten minutes before reconnecting handpiece.

When re-installing a collet or installing a new collet, the collet lock screw must be in the collet before you screw the collet into the spindle - Fig. 5. The collet lock screw must be threaded into the collet to a depth of approximately 5mm, (3/16″) from the back-end of the collet - Fig. 4. 6. Check to insure that the collet release lever is in the fully opened position - Fig. 1. Screw the collet into the spindle while gripping the exposed spindle with your fingers. Do not screw the collet in too far. (Do not close the three slots in the collet.) 7. Collet Adjustment Procedure: Insert a bur with a 2.35mm shank into the collet. If the bur does not enter the collet, un-screw the collet counter-clock wise until the bur fits in freely, and re-insert the bur. The collet tension is adjusted by rotating the collet clockwise to tighten, and counter-clock-wise to loosen - Fig. 6. The collet is adjusted properly when a SLIGHT resistance is felt when moving the bur in and out with the collet release lever in the fully opened position. Next, grip the spindle with the soft-jaw pliers, and tighten the collet lock screw securely with the Allen Wrench - Fig. 2. 8. Insert a 2.35mm shank bur into the collet, and close the collet release lever. Using a cloth to protect your fingers, try to pull the bur out to test the collet’s holding strength - Fig. 7. If you can remove the bur by hand, the collet is too loose. If the collet is too loose, loosen the collet lock screw, refer to Collet Adjustment Procedure above and re-adjust the collet until the bur cannot be removed with the collet closed. 9.
