will cause kickback.
1. To attach the 53033 flex-shaft (sold
separately) to the Rotary Tool remove the
housing cap from the tool as shown in
Figure 1. Then press the shaft lock and
unscrew the collet nut and remove the
collet. Install the driver cap on the motor
shaft as shown in Figure 2 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).
2. 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 co!let 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.
Available Collets
No. 53065 Collet Nut Kit -Includes one
1/8", 1/16", 1/32" & 3/32" collets and collet
nut.
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. Automotive wheel bearing
grease should be used.
Reattach the flex-shaft to the rotary tool.
