ASSEMBLY
MOUNTING THE SAW TABLE TO SAW BODY
See Figures 16 - 18, pages 25 - 26.
 Remove throat plate and pull table pin out of saw table.
 Standing at the front of the saw, guide saw blade through
slot in saw table.
 Rotate saw table so slot is facing the front of the saw.
 Slide table screws into trunnion support.
 Secure saw table using table lock knobs.
WARNING:
Unit is shipped with blade installed. Do not plug
in or operate unit unless the blade is adjusted and
aligned per section titled "Installing and Adjusting
the Blade". Failure to do so could result in possible
serious personal injury.
 Replace throat plate and table pin.
ADJUSTING BLADE TENSION
See Figure 19, page 26.
As you become familiar with the saw, you may find it nec-
essary to change the blade tension from the initial setting.
Changes in blade width and the type of material being cut
will have an effect on blade tension.
Keep in mind that too little or too much blade tension can
cause blade breakage.
 Turn blade tension knob clockwise to tension blade. A
gauge on the upper wheel slide bracket indicates the
approximate tension according to the width of the blade.
Initially, set the blade tension gauge to correspond with
the blade width.
NOTE: Adjustments of blade tension can be made at
anytime.
 Never increase blade tension so tight as to completely
compress the spring. When completely compressed, the
spring can no longer act as a shock absorber.
TRACKING THE BLADE
See Figure 20, page 26.
Blade must be properly tensioned before adjusting blade
tracking. Make sure blade guides and blade bearings do
not interfere with the blade.
 Open upper cover. Rotate the wheel forward by hand and
observe the position of the blade on the wheel. It should
be in the center.
 If adjustment is necessary, loosen jam nut, tighten knob
slightly to move blade toward rear of machine. Slightly
loosening the knob will cause the blade to track toward
the front of the machine.
 Tighten nut after blade is tracking in the center of the
wheel.
ADJUSTING TABLE STOP BOLT
See Figure 21, page 26.
 Loosen table lock knobs and tilt table until it rests against
table stop bolt.
 If an adjustment is necessary, loosen jam nut and turn
table stop bolt left or right to raise or lower the stop.
 Tighten jam nut to hold table stop bolt in place.
 Tighten table lock knobs by turning clockwise.
SQUARING THE SAW TABLE TO THE BLADE
See Figure 22, page 27.
 Turn the lock knob counterclockwise to unlock the blade
guide.
 Raise the blade guide as far as it will go. Turn the lock
knob clockwise to retighten.
 Place a small combination square on the saw table against
the blade.
 Loosen the table lock knobs by turning counterclockwise
and rotate the saw table up or down to align table 90° to
blade (0° position).
 Retighten the table lock knobs by turning clockwise.
 Check squareness of the saw table to the blade. Make
readjustments if necessary.
 Loosen screw on scale indicator with a Phillips screwdriver
and align scale indicator to zero.
 Tighten all screws securely.
ADJUSTING UPPER BLADE GUIDE
See Figures 23 - 24, page 27.
 Loosen lock knob and raise or lower upper blade guide
to just above the material being cut.
 Tighten lock knob. Make sure blade guides are still flat to
the blade. If adjustment is necessary, loosen lock knob
and rotate assembly until blade guides are flat to the
blade.
