far as it will go, and then back the shank out until

the cutters are approximately 1/8" to 1/4" away

from the collet nut face. With the bit inserted

and the spindle lock fully engaged, firmly tighten

the collet chuck assembly in a clockwise direc-

tion with the 27mm wrench. To avoid damage,

never tighten the collet chuck unless a bit of the

proper shank size is inserted.

CAUTION!

To minimize run-out and ensure

proper gripping, the bit should be inserted into

the collet as far as possible, and never less than

5/8".

CAUTION!

Do not use router bits greater

than 2-5/8" in diameter as they will not fit

through the base casting.

Removing the Router Bit

To remove bit, use the spindle lock and wrench

as described above, and turn the collet chuck

assembly 7 in a counter-clockwise direction.

Once the collet chuck assembly is loosened,

continue to turn the collet chuck until it pulls the

collet free from its taper, and the bit can be

removed.

NOTE: The collet chuck is self-extracting; it is

NOT necessary to strike the collet chuck to free

the router bit.

Collet Chuck Care

With the router bit removed, continue to turn

the collet chuck counter-clockwise until it is

free of the shaft. To assure a firm grip, occa-

sionally blow out the collet chuck with com-

pressed air, and clean the taper in the armature

assembly shaft with a tissue or fine brush. The

collet chuck is made up of three component

parts as illustrated; check to see that the retain-

ing ring 15 is properly located around the collet

16 and seated in the in-

ner groove of the collet

chuck nut 17 and lightly

thread the collet chuck

back onto the armature

shaft. Replace worn or

damaged collet chucks

immediately.

Plunge Lock/Release Lever

To release the plunge lock/release lever 13

grasp the router handles firmly with both hands

and press the lever with the thumb of the left

hand. The motor may then be raised or lowered

to the desired position. The plunge lock/release

lever is spring-loaded, and will hold the router

motor in position when pressure on the lever is

released. When plunging, always apply uni-

form firm pressure to both handles to avoid

cocking the motor on the posts.

The depth indicator rod 1 and the revolving

depth turret 5 are used to control cutting depth

as follows;

With the bit installed, gently lower the motor

until the tip of the router bit just contacts the

level surface the router is sitting on. This is the

"zero" position, from which further depth ad-

justments can be accurately made. To set a

desired depth of cut, rotate depth turret until the

lowest step is aligned with the depth indicator

rod. Loosen depth indicator lock/release knob

3 and lower the depth indicator rod until it

contacts the lowest step of the turret. The read-

ing of the red indicator line along the depth

indicator scale 2 now indicates the point at

which the bit just contacts the work, and is used

as a reference point to set the desired depth of

cut.

EXAMPLE: With the bit just contacting the

work surface, depth indicator rod 2 reads 3/4"

with the tip of the rod in contact with the turret.

To achieve a 1/2" depth of cut, loosen knob and

move the rod upward until the red line indicates

1 1/4", and tighten knob. Plunging the router

until the depth rodcontacts the depth turret will

now move the bit into the workpiece 1/2". To be

certain that your settings are accurate, you may

want to make test cuts in scrap material before

beginning work.

It is possible to make progressively deeper cuts

by starting with a higher flat on the depth turret

and rotating the turret to progressively lower

stops until the final cutting depth is reached.

The threaded guide rod 9 is fitted with three stop

nuts 6. When not in use, these nuts should be

snugly seated at the top and bottom of the rod so

that they do not interfere with the plunge action.
