BAND SAW
MODEL NUMBER
LIST FOR
You now own a Band Saw which is the product of
extensive engineering research and thorough test_
ing_ Accurately machined parts built to high in-
spection standards are carefully assembled to make
sure this Band Saw will deliver top quality perform_
ance. These features have all been combined with
an attractive appearance to create a tool that is a
pleasure to operate and a welcome addition to your
shop. This Band Saw can be used for cutting curves,
circles, or any irregular shape as well as straight rip-
ping or cutoff.
To prevent damage in shipment some of the parts
were disassembled from the tool, These parts are
listed below, Be sure they are all accounted for be-
fore discarding any of the packing material.

ASSEMBLY:
Remove the 4 cover knobs and slMe the
cover off studs, see Fig. I,
Place the 4 mounting bol_, No.
38_ in the four holes of the trunnion support bracket
and mount the _bh and suppo_ bracket assembly
to the frame as shown in Fig_ 2. Leave thee 4 bolts
loose enough to a|Iow the entire assembly to be
shifted. Place the blade _ntst rolle_ Nos. 30 and
49, in tool as shown in Fig. 2_ .
Before proceeding wi_ ass_bllng be sure the
table is locked so that the _ stop v:.rew, No_ 4, is
resting on the support bracket, No_ 14.
Locking of _e table h accomplished _th the _ble
flit lock handle as shown in Fig. I.
install the saw blade with the teeth pointing
down_ and away from d_e saw blade guides. Apply
enough tension to the blade to take up the slack by
turning the blade adjus_ kn_, see Fig. I.

INSTALLATION=
Securely "bolt the Band Saw to a solidly "built bench
checking each foot and adding spacers if necessary
to provide good contact with the bench, it is sug-
gested that the bench be of sufficient height to bring
the saw table about elbow level.
Three holes have been provided to secure Band
Saw to bench. There are two holes in the front foot
on the outside of the tool. The rear foot has one: hole
accessible from inside the:cover.
We suggest that a 3-inch square hole be cut in the
bench top directly back of the front foot to prevent
the accumulation of saw dust,
The motor may be installed behind or below toot.
termined after the motor position has been selected
by measuring with a steel tape around the outside
of the pulleys, not in the grooves,
LUBRICATION:
A special double row bail bearing built into the drive
shaft and the two single row ball beatings in the idler
wheel have been packed with lubricant and sealed at
the factory_ They require no further attention.
The blade thr_troiled, as shown in Fig. 2, should
be lubricated occasionally. Other moving and slid-
ing parts such as the guide slide bar, No. 46, and
table trunnions_ Nos. 12 and 16, may require occa_
sional lubrication to maintain smooth operation.
CONTROLS=
The table tilt lock handle locks the table in any posi-
tion from 90* to 45* with _w blade.
The table _t pointer indi_tes the: table angle on
the calibrated trunnion scale.
The blade back up the blade: for both lateral
and direct thrust.
The blade guide el lo_k knob controls the
upper assembly in relation _ table surface for vari-
ous work piece thicknesses.
The blade ali_ment knob provides a means of
tilting the upper wheel for correct _w blade tracing.

MOTOR:
A I/3 horsepower 1750 R.P,M. motor is recom-
mended for general usage.
Install the motor so that the direction of rotation
of the drive pulley, see Fig. I, is counter-clockwise
when viewed from the drive pulley side of the tool.
SPEED=
The above motor equipped with a 2-inch diameter
pulley .will give an arbor speed of approximately
640 R,P,M, This is recommended for general use
with wood and similar matetial.
When purchasing the motor pulley be sure to spe-
cify the shaft diameter of your motor and that the
pulley is for a l/2-inch V-belt,
BELT:
The drive pulley is designed for use with a standard
N-inch V_belt, The length of this belt may be de-
ADJUSTMENTS:
This tool was completely checked and tested under
power at the factory. Rough handling in shipment
may have caused some misa]ignmenL Check the fol-
lowing points to insure proper operation.
Proper Made tension may be _t by raising or
lowering the upper wheal assembly. This is done by
turning the bhde tension adjusfmg knob as shown in
Fig. |. When properly adjusted the blade should de_
press the rubber facings on the wheels slightly and
also may be deflected by thumb pressure exerted be-
tween the first two fingers.
The saw blade must run consistently on the approx-
imate center of the wheals. The wheels are c_owned
to accomplish this, with the upper wheel being tilt-
able. Rotate the mechanism by hand and if the saw
blade tends to ride off d-_e wheels loosen the lock
_ob, as shown in Fig. I. Turn the blade _gnment
knob slightly in or out until _e blade returns to its
proper position.
When blade tracks consistently 6ghten the lock
knob.
Saw guide _emMies are provided both above
and below the table to support the blade against
lateral and direct thrust,
_'_e upper saw guide a_mbly, Fig. 3, m_t operate
so that the distance from the back of the saw blade
to the _rust roller remains the same throughout the
entire up and down movement of the a_embly. If

adjustment is nece_ remove the cover and _rn
the upp_ _w ra_de _ g _, Fg. 3,
either in or out as required._ When adjustment is
completed lock the adju_.ing screw log nut, Fig. 3,
to maintain adjustment.
NOTE: After a f_€ hou_ of op_a_on tighten all
pulley set screws.
Following are several common _es of Band _w
blade br_kag_ Avoid thee _tuafions by fr_uenfly
and _mce from your blade.

Adjust the saw guide as_mblies so that the hte_l
saw g-_des_ see Fig. 2, when adjusted, will contact the
blade on the solid portion only, not on the: teeth or
necessary. Lock the saw guide assemblies in position.
The hteral saw gmd_ must be set as dose as pos-
sible to the blade without binding it at any point or
deflecting it sideways. Lock _e set screws securing
the lateral saw guides.
The bhde thrust rollers _ shown h Fig. 2 should
be set the thickness of a piece of newspaper, _e Fig.
3, from the back edge of _e blade. Adjustment of
the blade thrust rollers may be accomplished by
loosening the holder set _ews (Fig, 2) and
moving both _e holder bearing and thr_t taller in
or out by turning the back Up scrcw_ Fig. 3, until the
roller is in the correct position. Re-lock the holder
tighten the hold_ b_.ng s_ _ _e Fig. 2, only
slightly in bo_ the upper and lower saw _ide hrack-.
