Assembly
Warning: Always unplug Rotary Tool before changing accessories, changing collets or
servicing your Rotary Tool.
Collet nut
To loosen, first press Shaft Lock Button and rotate the shaft by hand until the lock engages the
shaft preventing further rotation.
Caution: Do not engage lock while the Rotary Tool is running.
With the shaft lock engaged use the collet wrench to loosen the collet nut if necessary. The collet
nut must be loosely threaded on when inserting an accessory. Change accessories by inserting
the new one into the collet as far as possible to minimize runout and unbalance. With the shaft
lock engaged, finger tighten the collet nut until the accessory shank is gripped by the collet.
Avoid excessive tightening of the collet nut when there is no bit inserted.
Collets
Two different size collets to accommodate different shank sizes are available for your Rotary
Tool. 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 tool shaft. Replace collet nut on the shaft.
Caution: 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.
Flex-shaft attachment
Warning: Read and understand the tool manual and these instructions for the use
of this accessory with your tool. Failure to follow all instructions listed below may
result in serious personal injury.
Wear ANSI compliant eye protection. The operation of any power tool can result in foreign
objects being thrown into the eyes.
Do not operate the flexible shaft with a sharp or multiple bends. Over bending the shaft can
generate excessive heat on the jacket or hand piece and may cause the flexible shaft to disengage
from tool. The minimum recommended bend radius is 5”
Always hold the hand piece firmly in your hands during the start-up. The reaction torque of
the motor, as it accelerates to full speed, can cause the shaft to twist.
Not for use with router bits or other large diameter cutting bits. Large diameter cutting bits
can cause kickback and loss of control when used with the flexible shaft.
Do not remove end ferrule while tool is running.
