ASSEMBLY INSTRUCTIONS FOR IOSO BELT
GRINDER AND IO83 FLOOR STAND
In an open area, arrange the four legs of the floor stand so each pair of matching legs, BG-56A and
BG-568, are on opposite corners. The holes for the 1084 Motor Mount should face the front and rear.
2. Using the BG-59 Nuts and Bolts provided, loosely assemble the floor stand connecting a BG-56A
Leg to a BG-56B Lcg, with BG-57 Short Brace. Repeat the procedure with the other pair of legs;
thcn connect the two assembled pair of legs with the BG-58 Long Braces.
Befort: tightening the floor stand, put the l0B4 Nlotor I\tount together using the shoulder bolts and
nuts. The two sections of the motor mount should swing loosely. Attach the motor mount to the
floor stand. Do not attach motor until after llelt Grinder is attached to the floor stand.
With the l0B3 Floor Stand loosely assembled, place the l0B0 Relt Grinder on top of the floor stand
and attach with four nuts and bolts, hand-tight. 'l'hen, tighten the floor stand and belt grinder in place
with a screwdriver and wrench.
The ll4 horsepower motor should be attached to the motor mount, tightening the nuts and bolts to
the motor bracket, hand-tight.
After aligning the motor pulley with the BG-30 pulley, tighten the motor to the motor mount with
a wrench and screwdriver.
Place the V belt over the BG-30 pulley and motor pulley, letting the weight of the motor provide
the proper belt tension.
Once the main unit and floor stand are assembled, the BG-I9A Table can be placed on the BG-33
Table Bracket Pivot and held in position with the set screw on the table. After tightening thc set
screw to hold the table in place on the BG-33 Table Bracket Pivot, you can then adjust the tension of
the 2-126 Table Adjusting Bracket Screws
so that the BG-33 Table Bracket Pivot
will turn for adjustment of the table
angle. These screws should be tight enough
to hold the table in place, yet loose enough
so that the table angle can be moved easily.
9. The optional BG-61 Belt Guard may be
added by loosening the Z-lI9 End Cap
Screw and placing the slot of the guard
beneath the head of the screw. The guard
will be positioned over the top of the
BG-27 Upp"r Pulley.

BELT INSTATLATION
The BG-B upper arm is mounted to the BG-r corumn and has spring tension created by the BG'ro upPer
arm spring. The following procedure should be used to install new belts:
l. With the table tilted forward depress BG-B upper arm'
Place belt so it runs over BG-27 upper pulley and in front of the BG-6 backstop'
Thread the belt around the BG-22lower pulley and the BG-f 4 idler pulley'
The abrasive belt will run in a counter-clockwise direction when looking at the grinder from the
right side. Make sure the arrow on the back of the belt points in this direction. If the belt travels
inthe opposite direction of the arrow, it may separate after very little use'
when the BG-8 upper arm is released the belt will have the proper tension'

TOOTH POINTS
Plan to concentrate on the face of the saw
tooth. The face on most rip saw blades is
sharpened straight across so it has no bevel-
A combination blade has a bevel of 5-10 degrees
on the face, while a cutoff or crosscut saw may
have a bevel up to 25 degrees on the face.
With the motor turned off, place the saw on
the work table so that the face of the saw
tooth is parallel to the abrasive surface of the
belt. This will insure that you are not changing
the hook angle already gound into the sawblade.
Draw a chatk line around the blade far enough
tb serve as a guide, to insure equal grinding on
each tooth. As each tooth is sharpened, bring
the teeth against the chalk line to maintain
the hook anglc.

BEVEL TOP OR BACK JUST
TO THE TOOTH POINT BEVEL SHOULD CURVE SMOOTHLY
INTO BACK OF TOOTH
BACK.BEVELING
Beveling the top or back of a saw tooth can also be accomplished on grinder. Adjust the table to the bevel
angle required on the top or back of the tooth. Plan to make the first contact of the tooth against the belt
slightly in back of the tooth point. After the sawblade has contacted the belt, use pressure to grind the top
until the bevel just extends to the tooth point. Do not grind off the tooth point, as this will cause the saw
to be out of round. Grind this bevel so the end of the bevel curves smoothly into the back of the tooth.
A general guide to the amount of metal to be removed is the size of the flat or shiner left by jointing. If
the shiner is small, you can complete the sharpening in one pass around the blade. If there is a relatively
large shiner, it is better to make several passes around the blade.
Almost any style blade can be sharpened on the abrasive belt grinder. If the style is new to you, it's best
to adjust the table angle and experiment with a sawblade before actually sharpening it on the belt grinder.
Page 13

SHAPING SAW TEETH
After a saw has been filed by hand, or ground
several times, the saw teeth may need reshaping.
The coolness of the l0B0 makes it ideal for
reshaping, as it enables you to stay on the tooth'
ON THE IOSO BEIT GRINDER
bringing it back to shape without worrying
about overheating or bluing the tooth. Basic
shaping of saw teeth should be accomplished
with table kept flat at 90 degrees to the bilt. I
I
I
I
The belt grinder is especially useful for shaping Style C teeth, as the one-inch wide belt lets you do the
entire top of the tooth in one pass. Also, this step gives you the back clearance required for properly
sharpened sawblades. With the motor turned off, set the sawblade on the table so that the top of the tooth
is parallel to the belt. Mark the circumference of the sawblade with a chalk line.
Page 14

Using the chalk line as a guide, sharpen each tooth to the same back clearance.
Saw teeth with curved backs can also be shaped. Start grinding just in back of the tooth point. Turn
the saw to grind down the back of the tooth to bring the curve back into the rounded gullet smoothly
and evenly.
T
t
I
tCutoff saws and some combination blades such as
Style S blades will have a bevel all the way down
the back of the tooth. When shaping this type
blade on the grinder, tilt the table to the recom-
mended bevel, rather than at 90 degrees to the
belt. In this way, when the final bevel ginding is
accomplished on the sawblade, you will not have
to remove an excessive amount of metal.
Pagc 15

, SCISSORS
Although scissors, like many other tools, can be sharpened, without a holder, we recommend using the
#264 tool holder until familiar with the basic operation. Clamp the blade to be sharpened in the holder,
with the beveled edge down. Tilt the table to the desired (3 degree to 5 degree) angle and make a light pass
across the belt, removing only enough metal to create a sharp cutting edge. Grind free hand matching any
curve of the blade.

I
I
PINKING SHEARS
Sharpened in a manner similar to scissors, plan
to sharpen only the beaeled cutting edge. Neuer
attempt to sharpen the V-grooues. If the grooves
have previously been filed or sharpened, the
shears should be returned to the manufacfurer
for factory service.
Reproduce the original bevel as closely as
possible. Place the shears on the work table
or in the tool holder, positioning the table to
match the bevel of the shears. After making a
light pass across the abrasive belt, visually inspect the area being sharpened and readjust table tilt if
necessary. Taking light passes, follow the natural contour of the blade. Remove only the minimum
amount of metal for a sharp edge.
You may find it necessary and
more convenient to disassemble the
shears prior to sharpening. A tool
to remove the special type fulcrum
nut can be made from a common
bottle cap opener as shown in the
picture at right. After sharpening
be sure all parts are replaced in
their original order. Clean all parts
and applylight machine oil sparingly.

CHITIEI,s
Clamp chisel in the 264 tool holder bevel-edge
down. Tilt the work table so that the bevel
rnatches the bevel on the chisel. To insure a
straight grnd, clamp a guide on the table and
slide the holder and chisel across the belt with
the holder resting on the guide.
t,SIlTG THE HOLDER
FIRST BEVEL CUT CORRECTED BEVEL CUT
If the shaft of the chisel is too short to fit
in the tool holder, the grinding may be
done free-hand, resting the chisel on the
work table;or by holding the chisel securely
in your hand. Make a light pass - if the
bevel is not exactly straight, move the
handle of the chisel to the right or left
until the bevel angle is straight with the
shaft of the chisel.
