OPERATING INSTRUCTIONS

Disengagement of the Flex-Shaft

The flexible shaft may become disengaged if the motor of your rotary tool is not elevated higher than the working end of the flex-shaft. The #2222 Rotary Tool Stand is recommended to hold the rotary tool at the proper height.

Collet and Accessory Assembly

The collet assembly consists of a collet nut and collet. Take the collet nut and collet that were removed from your tool in step 2 and 3 and insert them into the tip of the flex-shaft handpiece.

Step 4. Install the driver cap on the motor shaft and tighten.

! CAUTION	To prevent damage to tool, do not
	overtighten driver cap. Tighten

the driver cap finger tight and then tighten an additional 1/3 turn with the wrench. (Wrench included with your rotary tool kit)

STEP 5

Step 5. Attach by screwing the collar of the flex-shaft to the rotary tool. Make sure the square end of the center core engages the square hole socket in the driver cap.

! CAUTION	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.

Insert an accessory or bit as deeply as possible to avoid wobble during use. With the shaft lock button engaged on the flex-shaft handpiece retighten the collet nut.

Collet Removal and Replacement

Four different size collets to accommodate different shank sizes, are sold separately 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.

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

grease will cause the unit to overheat. Dremel shaft lubricant No. 5990952 or automotive wheel bearing grease should be used.

Reattach the flex-shaft to the rotary tool.
