Step 2. Unscrew the housing cap from the tool.
Step 3. Remove the collet.
Note: If the collet nut and collet are not removed from
the motor shaft, the tool will not function properly.
Step 4. Install the driver cap on the motor shaft and
tighten.
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. 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.
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.
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.
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.
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.
