Figure 1

Your Craftsman Saw is shipped complete (without
motor) in one crater To open crate, remove lid and un-

fold sides-- then unbolt saw from wood base. The crate
bolts, in some cases, may be used for mounting the motor

to the motor' mount assembly (N). Before discarding
packing material, examine it carefully for loose parts_

Your saw is shipped with the following loose parts wrap-
ped separately and packed in same crate with the saw

(see figure 1) : Rip fence rack (J), three screws and lock

washers (D), rip fence (F), miter gage (K), motor
mount (N), motor pulley (S), V-belt (T), arbor nut
wrench (M), and Alien wrench (U)o Thoroughly clean

the saw and these loose parts with a dry cloth. Remove
the rust-preventive coating on the saw table by"wiping

it off with a cloth soaked in kerosene,

NOTICE

The saw guard assembly and splitter blade brac-

ket (Part 72, Fig° 4) are not furnished with the
saw because of Government orders restricting
the use of aluminum. The above assembly may
be purchased when available, from Sears, Roe-

buck and Company under Catalog Noo 9-279io

CHECK ARBOR NUT- Remove two screws (B, fig, 1)

and lift out the insert (A, fig. 1). Check tightness of

saw arbor* nut (part 6362, fig,. 5_, :
using wrench (M, fig. 1)_ Re-

place insert and screws_ " *.......

AZIGN SAW BLADE WITH
TABLE GROOVES _i.Using ele-

vation hand wheel (A, fig. 2),
set saw blade for deepest 'cut.

Make pencil mark Qn tooth that
is just above table top at front of

blade. Measure distance from this
tooth point to right-hand table

groove (L, fig_ I). Rotate blade by hand to place this
same tooth just above table top at rear wthen again

measure distance .from tooth point to right-hand groove°
The two measurements must be :exactly equal, iIf 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 trunnious until the two measure-
ments are equal, then retighten the screws. Again Check

measurement.

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

the front skirt of the saw,tabIe, using the three screws
and. _l°ck'washers (D, fig.. 1). Be sure to position rack

with gear teeth facing downward M-and with top edge of
rack parallel with the top of table. Pull the rip fence knob

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

fi I to slide over rack ( ,fi 1)--then lacetheri

fence on the saw table as shown in figure 2. A Slight
pressure must be exerted On the rip fencelo :cause itt0

seat properly on the rack. This is necessary because there

are two bar alignment springs which act on the :inner !iP

of the rack to hold the fence in continuous alignment.

Slide fence along rack, noting clearance between fente

and table top. If an), part of the fence (other :then the
sliding pad at the rear) drags on the table top, or if the

clearance between fence and table varies appreciably, as
fence is moved,..rack (J, fig. 1) must then be readjusted.
This can be done by again loosening screws (D, fgg 1)

to reposition the rack.
ADJUSTING RIP I;ENCE PARALLEL TO SAW

BLADE _ Place the rip fence next to the right-hand
_able groove (L, fig. 1) and clamp

it in place by pushing down on
the cam clamp lever (H, fig. 1).

Fence should be perfectly parallel
to the groo,,eo If not, loosen the

four screws (parts S-1264 and
S-1265, fig,. 4) which secure the

guide to the fence. Align fence
with groove then retighten
screws.

)

Before attempting to use your saw; assemble the parts as
instructed below _ and be sure to make all of the checks

and adjustments given in these instructions° This is im-

portant! Even though all adjustments are carefully

checked before saw is shipped, rough handling in transit
may make some readjustments necessary. Unless saw is

maintained in proper adjustment throughout, you cannot

do the fast, accurate work for which it is designed.

MOUNTING THE MOTOR _ Mount the motor (see
Motor Specifications) to the motor mount assembly (N,

fig, 1) _ then mount the motor support assembly tO the

saw by sliding the two pins (O, fig. 1) into th e mounting
holes at the rear of the cradle. Place pulley :(S, fig. i)

on the motor shaft, line it up with the pulley on the saw

arbor, then tighten the pulley set screws. Install V-belt

(T, fig. I) over pulleys and adiust the belt tension by

_2_

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 ,s cor-
rect, clamp the motor support in place by tightening the

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

ADJUSI"ING MOTOR MOUNT TENSION. Tension
is adjusted by tightening the nut (part S-!2!5, 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 tlghten'mat to a ibcked position, o_ the studwill, be
sheared off when blade is raised or lowered.. A slklmg

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 p_opet 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 moto_ rails. Use a 1!2dnch wide belt with a

minimum length of 80 inches. Adjust the position of the

motor until belt clears al! obstructions through all po-
sitions of the saw blade,,

If saw is to be driven from a line shaft, use a belt 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 a 3450 rpm motor.
Motor should be 3/4 hp (for light duty) or one hp (fox

heavy duty)--in either an AC motor of a repulsion-
induction or capacitor type, or a compound-wound DC.

The motor shaft center should be approximately 4 inches

above the bottom of the motor base,. If this dimension
varies appreciably from 4 inches, it may be necessary to

obtain a belt of a different 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. These may be ordered
through any Sears Retail Store or Mail Order House°

EIEVATION HAND WHEEL (A)--on the front of

the saw, controls elevation of the blade (depth of
cut) as indicated on the DEPTH DIAL (B)°

CLAMP SCREW HAND1[E (E) _ on front of saw, locks

the tilt mechanism in any desired position. The

clamp screw handle operates like a socket wrench.

Tilt mechanism should always be locked before start-
ing work _ and should always be unlocked before
attempting to change the angle of tilt.

TIIT HAND WHEEL (C)_ on left side of saw, con-

trois the angle of tilto The saw blade can be tilted
from 0° to 45 °, as indicated on the TILT GAGE-

(D). 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 (F) _ is operated by pushing in the FENCE

KNOB (G) so that it engages a pinion gear with
the teeth on RACK (J), Turning the knob (G),

after pushing it in, will cause the rip fence to move
accurately across the table_ When the knob (G) 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 CI,AMP 1lEVER (H)_ is used to clamp the rip

fence in place after it has been moved to the position
desired,

CAUTION

Under no circumstances should a 5-inch motor

pulley be used with a 3450 rpm motor. The saw
blade speed resulting from such a pulley ratio

would be dangerous. Do not use a 21/z-inch
motor pulley with a 1750 rpm motor--this will

not give satisfactory saw performance_

The following controls should be tested until the opera-

tot is thoroughly familiar with their uses. See figure 2,

MITER GAGE (K) _ is used in table grooves as a guide

for the wo_kpiece when the fence is not used_ The
angle of the gage can be adjusted by loosening

C1[.AMP KNOB (1[,) and positioning gage as indi-
cated by the dial and pointer (K).

bIITER GAGE STOP ROD (M)_ can be adjusted in

length by loosening WING NUT (N). This rod is
used as a positioning guide for the end of the work-

piece.

CAUTBON

Under' no circumstances should a blade with a
diameter greater than 10 inches be used with

this saw.
