Assembly - (cont.)

Screw the flexible shaft onto the Rotary Tool housing being sure that the square end of the center core engages the square hole socket in the driver cap Figure 3.

Do not pull out center core to engage into driver cap. This could cause disengagement of center core from handpiece. If tool stops when shaft is bent, center core may be lodged in driver cap. Loosen shaft and remove core from driver cap. Then screw flexible shaft onto rotary tool housing again.

Flex-Shaft Collet Assembly

The collet assembly consists of a collet nut and collet. To change bits use the wrench and a bit. Insert the shank portion of any bit (1/8" shank recommended) through the opening in the flex-shaft hand piece to lock the shaft. With the shaft secured, use the wrench to loosen or tighten the collet nut as shown in Figure

4.With the collet nut loose, insert an accessory or bit as deeply as possible to avoid wobble during use. Retighten the collet nut.

Collet Removal and Replacement

Four different size collets to accommodate different shank sizes, are available for your flex-shaft. To install a different collet, remove the collet nut and remove the old collet. Insert the unslotted end of the collet in the hole in the end of the flex-shaft. Replace collet nut on the shaft. Always use the collet which matches the shank size of the accessory you plan to use.

Never force a larger diameter shank into a collet.

Flexible Shaft Lubrication

The flexible shaft should be lubricated after every 25- 30 hours of use. To lubricate, unscrew the flexible shaft assembly from the motor housing. Pull the center core out of the flexible shaft assembly. Wipe a very thin film of a good quality, high temperature grease on to the center core.

!To prevent damage to tool do CAUTION not over grease shaft. Too much

grease will cause the unit to overheat. Automotive wheel bearing grease should be used.

Reattach the flex-shaft to the rotary tool.

!Do not operate the flexible shaft WARNING with a sharp bend (A). This can

generate excessive heat and will reduce tool and flex- shaft life. The recommended minimum is 6" radius (B).
