times. If you cut a thin piece of steel with
a coarse tooth blade, you may rip off teeth
or break the blade. In general, the thinner
the material or the stack of material, the
finer the blade tooth should be.
Be sure the teeth of the blade clear the
outside slot of the guide blocks.

ASSEMBLY AND ADJUSTMENT PROCEDURE
ADJUSTMENT TAKE-UP
The reduction
unit is mounted on an eccentric hub and bearing assembly #6006 (see
Figure 1) that can be revolved to the right slightly to take up any undue slack in the drive
chain and V-belt.
MOTOR BELT INSTRUCTION
Motor belt can be tightened by turning hand wheel on base to the left. DO NOT have
belt too tight.
ASSEMBLY
OF TABLE ON SAW
First, remove the table slot screw #6007-9 from the table. (See Figure 5.) Guide
the blade through the slit in the front edge of the table #6007 and then rest the two front
table lugs on the 3/4" round table mounting
shaft #6007-3.
At the same time slip the
rear table lug over the 3/8" table mounting pin #6007-2 in the frame until the lug con
tacts the frame. Finally, lock the front lugs to the mounting
long studs and washers #6007-1.

UPPER WHEEL ADJUSTMENT
sheets.
AND TRACKING THE BLADE
Place the blade on the rubber tires of both the upper and lower wheels and shift the
back edge of the blade up against the flange of both wheels, then, increase the tension on
the blade by screwing the riser bolt #6002-8 to the right (see Figure 4.) Care should be
taken that the tension is not too great to interfere
with free movement
of
the wheels. Too
great a tension on the blade is a common cause of blade breakage. When tension has been
adjusted,
revolve the wheels slowly forward by hand. NEVER ADJUST ANY PART OF
THE SAW WHILE MOTOR IS RUNNING. If the blade creeps away from the flange on the
upper wheel, tilt the upper wheel in at the top slightly by turning the upper wheel bracket
adjusting bolt #6002-4
against the flanges, in which position the blade is tracking properly.

This will cause the blade to gradually creep up

SETTING AND ADJUSTING THE BLADE GUIDES
After the blade has been "tracked" properly, the blade guide brackets
#6003-1
