5. Operation
Disconnect the power plug from the power source before any assembly, adjustments, or
adding/removing accessories. Follow this preventative step to reduce the risk of the tool
coming off accidentally and the risk of damage to the workpiece and injury to the
operator.
Collet Nut
•
To loosen (1) the collet nut (a), first press the shaft lock button (b) 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 (c) 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 run out and unbalance.
•
With the shaft lock engaged, finger-tighten the collet nut until the accessory shank
is gripped by the collet.
Using the wrench, completely tighten (2) to fully secure the accessory.
NOTE: Avoid excessive tightening of the collet nut when there is no bit inserted.
Loading an Accessory in the Tool
1. Press down the shaft lock button and hold it down.
2. Apply the collet wrench to the flats of the collet nut and turn it anticlockwise to
loosen it.
3. Place the accessories shank into the collet as deep as it will go.
4. Press and hold the shaft lock button.
5. Tighten the collet nut by turning it finger-tight in a clockwise direction until the
accessory is firmly clamped. Completely tighten using the wrench.
Using the Tool
•
Always hold the tool away from your face. Accessories can be damaged during
handling and can fly apart as they come up to speed.
