out until the cutters are approximately 1/8" to

1/4" away from the collet chuck face. With the

router bit inserted and the spindle lock fully

engaged, tighten the collet chuck assembly

firmly in a clockwise direction, (viewed from

under the router), with the wrench supplied. To

avoid damaging the collet chuck, never tighten

the collet chuck unless a router bit of proper

shank size is inserted into the collet.

To ensure proper gripping of the router bit and

minimize run-out, the shank of the router bit

should always be inserted at least 5/8".

CAUTION!

To prevent damage to tool. Do

not tighten collet without a bit. NOTE: The bit

shank and chuck should be clean and free of

dust, wood, residue and grease before assem-

bling.

CAUTION!

Do not use router bits greater

than 1-5/8" in diameter as they will not fit

through the base casting.

Removing the Router Bit

Use the spindle lock and wrench as described

above, and turn the collet chuck assembly 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 router bit can be re-

moved.

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

NOT necessary to strike the collet chuck to free

the 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 re-

taining ring 21 is prop-

erly located around the

collet 22 and seated in

the inner groove of the

collet chuck nut 23 and

lightly thread the collet chuck back onto the

armature shaft. Replace worn or damaged

collet chucks immediately.

To release the plunge mechanism, grasp the

router handles firmly with both hands and press

the plunge lock/release lever 16 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 lock lever is released. When plunging,

always apply uniform firm pressure to both

handles to avoid cocking the motor on the

posts.

The depth indicator rod 3 and the revolving

depth turret 7 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 revolving depth

turret until the lowest step is aligned with the

depth indicator rod. Loosen depth indicator

lock/release knob 5 and lower the depth indica-

tor rod until it contacts the lowest step of the

turret. Slide the depth indicator 4 until the red

line indicates zero on the depth scale, indicating

the point at which the bit just contacts the work.

To set a desired cutting depth, slide the depth

indicator rod up until the red depth indicator

line attains the desired cutting depth, and se-

cure the rod in position by firmly tightening the

depth indicator lock/release knob. The desired

depth of cut may now be achieved by plunging

the router until the depth indicator rod contacts

the selected stop on the revolving depth turret.

To be certain that your depth settings are accu-

rate, you may want to make test cuts in scrap

material before beginning work. Once the de-

sired final depth has been set on the lowest

depth turret setting with the depth indicator

rod, it is possible to make progressively deeper

cuts by starting with a higher flat on the depth

turret and after each cut, rotating the revolving
