WARNING: TIGHTEN COLLET/NUT SECURELY to prevent the cutting bit
from slipping, if the collet/nut is not securely tightened, the cutting bit may
detach during use, causing serious personal injury.
NOTE: To ensure proper gripping of cutting bit shank and minimize run-out,
the shank of the cutting bit must be inserted into the collet/nut at least 5/8
inch.
CAUTION: To prevent damage to tool, do not tighten collet/nut without a
cutting bit installed.
REMOVING THE CUTTING BIT (Figs 3 and 4 see page16)
1. Turn router motor off and unplug from power source.
2. Remove router motor from fixed base.
3. Set the router motor upside clown on its top cap, with collet/nut pointing up.
4. Press spindle lock button to engage and lock the spindle sl-_qft and collet/nut, (Fig. 3).
5. Place the wrench on the colleVnut and turn counterclockwise and loosen cot-
let/nut slightly and remove cutting bit shank.
COLLET/NUT CARE
From time to time, inspect the collet/nut to make sure it is clean and is gripping
the cutting bit properly.. With the router cutting bit removed, turn the colleVnut
counterclockwise (with spindle lock engaged) until it is free from router motor's
spindle shaft.
Blow the collet out with compressed air, and clean the tapered inside of the cot-
let/nut with a tissue or fine brush.
Always make sure the cutting bit shank, collet/nut and router motor spindle are
clean and free of woodchips, dust, residue, grease and rust before installing.
Apply a slight amount of machine oil to spindle shaft if it looks dry.
Replace worn or damaged collets/nuts immediately,,
NOTE: The cotlet/nut is self-releasing; it is NOT necessary to strike the
cotlet/nut to free the router cutting bit. If cutting bit seems stuck after use,
loosen collet/nut a little more until it releases.
CUTTING BITS
Get faster, more accurate cutting results by keeping cutting bits clean and sharp.
Remove all accumulated pitch and gum from cutting bits after each use,
When sharpening cutting bits, sharpen only the inside of the cutting edge. Never
grind the outside diameter. Be sure, when sharpening the end of a cutting bit, to
grind the clearance angle the same as originally ground°
