ASSEMBLY
n Replace throat plate and table pin.
n Transportation and handling may have caused some
fasteners to loosen. Before operating, check all screws,
bolts and nuts to make sure they are snug. Operate
machine only after reading the entire operator's manual
including blade tracking, blade guide adjustments, and
safety rules.
ADJUSTING BLADE TENSION
See Figures 27 - 28.
As you become familiar with the saw, you may find it necessary
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.
n Unplug the saw and remove switch key.
n 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.
Another method of checking blade tension has to do with
the sound the blade makes when plucked like a guitar
string.
n Pluck the back straight edge on the coasting side
opposite the blade guides while turning the tension
knob. Sound should be a musical note. Sound becomes
higher pitched as tension increases.
Using either method to check blade tension can be
developed with practice.
n 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 29.
Blade must be properly tensioned before adjusting blade
tracking. Make sure blade guides and blade bearings do
not interfere with the blade.
n 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.
n If adjustment is necessary, loosen wing 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.
n Tighten nut after blade is tracking in the center of the
wheel.
