!ALIGN SAW BLADE WITH

TABLE GROOVES- Using ele-

vation hand wheel (A, fig. 2),

set saw blade for deepest cut.

Make pencil mark on tooth that

is just above table top at front of

blade. Measure distance from this

tooth point to right-hand table

groove (L, fig. 1). Rotate blade by hand to place this

same tooth just above table top at rear then again

g measure distance from tooth point to right-hand groove.

The two measurements must be exactly equal. If not,

loosen the three screws (part S-860, fig. 4) in each trun-

nion which secure the table trunnion (part 13, fig. 4) to

the table. Shift the two trunnions until the two measure-

ments are equal, then retighten the screws. Again check

measurement.

_our INSTALL RIP FENCE- Secure the rack (J, fig. 1) to

examine it carefully for loose rack parallel with the top of table. Pull the rip fence knob

(G, fig 1) out to pera_it the guide of the rip fence (F,

fig. 1)to slide over rack (J, fig. 1 ) then place the. rip

fence on the saw table as shown in figure 2. A shght

pressure must be exerted on the rip fence to cause it to

moving the motor support assembly towards or away from

the cradle. Motor should be allowed to rest or hang

against the belt to obtain the automatic belt tightening

feature- and belt should be snug. If adjustment is cor-

rect, clamp the motor support in place by tightening the

two square head set screws (part S-1267, fig. 4).

ADJUSTING MOTOR MOUNT TENSION, Tension

is adjusted by tightening the nut (part S-1215, fig. 4)

against the steel washer (part S-1261) and the spring

washer (part 6423). Nut should be tightened just enough

to reduce motor vibration when saw is operating. Do

NOT tighten nut to alocked position, or the stud will be

sheared off when blade is raised or lowered. A sliding

action is necessary because mount changes position as

blade is raised or lowered. Operate the saw by hand to

make certain that the belt has proper tension and that

mount changes position as it should.

If saw is to be driven by a large frame motor that cannot

be mounted on the motor support assembly, mount the

motor on motor rails. Use a 1/2-inch wide belt with a

minimum length of 80 inches. Adjust the position of the

motor until belt clears all obstructions through all po-

sitions of the saw blade.

If saw is to be driven from a line shaft, use abelt at least

100 inches long.

PLACEMENT OF MITER GAGE- The miter gage as-

sembly (K, fig. 1) can be used in either one of the two

table grooves.

This saw is designed to be used with a3450 rpm motor.

Motor should be 3/4 hp (for light duty) or one hp (for

heavy duty)- in either an AC motor of arepulsion-

induction or capacitor type, or a compound-wound DC.

The motor shaft center siaould be approximately 4inches

above the bottom of the motor base. If this dimension

varies appreciably from 4inches, it may be necessary to

obtain abelt of adifferent length. If a 1750 rpm motor

with a 4-5/8-inch shaft center height is used, a 5-inch

motor pulley and a 46-inch belt must be purchased. If

the motor shaft center height varies greater or smaller

than the above dimension, a correspondingly greater or

smaller belt length should be used. _hese may be ordered

through any Sears Retail Store or Mail Order House.

Under no circumstances should a5-inch motor

trois the angle of tilt. The saw blade can be tilted

from 0°to 45 °, as indicated on the TILT GAGE

(C). If the angle of cut (tilt) must be extremely_

accurate, the angle of the saw blade should be

checked with a protractor or with a board which is

known to be cut at the exact angle required.

RIP FENCE (E) -- is operated by pushing in the FENCE

KNOB (F) so that it engages apinion gear with

the teeth on RACK (H). Turning the knob (F),

after pushing it in, will cause the rip fence to move

accurately across the table. When the knob (F) is

pulled out to disengage pinion gear, the rip fence

can be moved across the table by hand. Keep the

saw table and rip fence clean. Dirt may prevent the

rip fence from obtaining proper alignment. Tapping

the fence lightly to assist the mechanism to find its

natural position, will help to maintain alignment of

the fence with the blade.

CAM CLAMP LEVER (G)m is used to clamp the rip

fence in place after it has been moved to the position

desired.

RiPPiNG

Ripping is the sawing of wood with the grain. It is

generally done with the help of afence as a guide to

position and maintain the work at the correct width for

the cut. Because the work is pushed along the fence, it

must have areasonably straight edge to make sliding con-

tact with the fence. Also, work must make solid contact

with the table, so that it will not wobble. Provide a

straight edge, even if this means temporary nailing of an

auxiliary straight edge board to the work. If workpiece

is warped, turn the hollow side down.

Use of the saw guard is recommended; and the splitter

should always be used in ripping operations. Wood cut

with the grain tends to spring the kerr closed and bind

the blade. If for any reason, splitter is not used, stop and

insert a wedge in the kerf just as soon as cut has passed

back of blade.

Set fence to desired width of cut, either by using the

scale on the fence guide bar, or by measuring the distance

between blade and fence. Fence is almost always used

on right-hand side of blade. Stand a little to the right

of center to avoid being sprayed with sawdust and to be

clear of work in case of a kickback. Start saw and ad-

vance work, using left hand to hold it down and right

hand to push it forward. AS cut nears completion, move

left hand to safe distance from blade, and push work

through with right hand alone. Never reach in back of

blade with either hand to hold work down.

When there is less than the

RESAWmNG

Resawing is the cutting of thick

boards into thinner ones. It is

a ripping operation. Small boards

up to 3_8-inch maximum width

--can be resawed in one pass;

but !arger boards up to 6l/_-inch

maximum require two passes, one

pass along each edge of the board.

When two cuts from opposite

edges are required, these should RHT

be made to overlap 1/2 inch from the approximate center

of the board. If the first cut is too deep, the kerr will

close and bind the saw on the second cut, with danger of

kickback. Also, when the kerr closes, the two sides of

the cut are no longer parallel to the saw blade, and the

saw will cut into them to spoil their appearance. Keep

same face of board against fence when making both cuts.

CROSSCUTTING

Crosscutting is the sawing of wood across r_ie grain.

Planks are milled with the grain running the length of

the plank. In crosscutting the long edge of the work is

placed across the table top. Therefore. the miter gage is

used as a guide instead of the fence. Most operators pre-

fer to use the left-hand table groove. In this case, the

left hand is used to hold the work in contact with the

gage and to push work and gage toward the blade. The

right hand is free to assist, as required. If right-hand

groove is used, hand positions are reversed.

Ordinarily the gage is placed in the table groove with the

bar in front. When work is so wide that it completely

chippers cannot.

A dado insert (part 9-2212, fig. 4) must be used to re-

place the standard table insert. Whenever two or more

chippers are used, stagger the swaged ends as evenly as

possible around the circumference. Fractional adjust-

ments in thickness of the head can be made by using

paper washers between the outside blades and chippers.

Dado head operations are much

the same as those with a standard

blade _ but the dado head takes

a bigger bite, so that workpiece

should be held more firmly. It is

good practice to use a hold-down

jig like the one illustrated.

When a groove wider than the _-

dado head is needed, make two

or more passes. Best method is

to use a notched stop block to po-

sition each successive cut. Block

is fastened to edge of table where

it can be used to position work

before starting the cut; but in such a position that it will

not contact work during the cutting operation. Space

cuts so that they overlap a trifle.
