Before tightening the collet on the bit, make sure the flutes (spiral portion) of the bit
are completely visible outside the collet. Clamping the collet on the bit flutes will
result in broken bits and possible injury.
5. When the bit is properly placed in the collet, depress the shaft locking button and turn the
collet nut clockwise by hand as far as possible.
6. Securely tighten the collet nut using the wrench.
SELECT APPROPRIATE MOTOR SPEED
Selecting the appropriate motor speed for your application will ensure smoother, more
efficient cutting action. Choose LOWER speed for cutting plastics. Choose HIGHER speed
when cutting wood and drywall, and to reduce “chatter” that may develop when cutting some
materials at LOW speed.
Change collet
Ill.5 + 6
The cutting bits for this tool are locked into place with a collet nut (1) and collet (Ill. 5). The 1/8”
collet (2) is used for holding 1/8” cutting bits and hobby tool accessory bits. The 1/4” collet (3)
is supplied for holding 1/4” bits.
To change from one collet size to the other:
1. Remove bit from the tool.
2. Turn the collet nut counter clockwise until it can be removed from the motor shaft (4).
3. Pull the collet out of the motor shaft and insert the new collet.
NOTE: Each collet is the same on both ends, so either end can be inserted into the motor
shaft.
4. Re-install the collet nut and slightly tighten it by hand.
NOTES:
a) Tightening the collet nut without a bit in the collet will cause the collet hole to become
smaller and make installing bits difficult. When storing the tool with no bit installed, leave
the collet nut loose.
b) Install the new bit as outlined in INSTALLING CUTTING BITS .
Installing freehand cutting guide
Ill.6
The freehand cutting guide is designed for basic freehand cutting with the cutting bit. It is
ideally suited for cutting electrical outlet holes in drywall.
WARNING: Do NOT use the freehand cutting guide with router bits. The amount of
control this accessory provides is insufficient and could cause you to lose control
and cause serious injury.
1. Open the freehand cutting guide collar (1) by pulling the locking lever (2) outward.
2. Slide mounting collar over the bottom of the motor housing (3).
NOTE: The mounting collar must be pushed onto the motor housing as far as it will go.
3. Lock the freehand cutting guide onto the motor housing by pushing the locking lever
inward toward the motor housing until it snaps into the locked position.
