4.6 SPECIAL OPERATION :
(1) While you are cutting a workpiece, if the saw blade suddenly jams in the workpiece, depress the
FRAME RAISE button to lift the saw frame immediately.
(2) The saw blade jamming in the workpiece is most likely because of :
a. Slippage occurring between saw blade and drive wheel. Tension placed on the saw blade is not
sufficient.
b. Slippage occurring between drive belt and motor pulley. Tension on drive belt is not sufficient or
belt is worn.
c. Broken teeth on saw blade.
d. Too blunt saw blade.
e. Too fine tooth spacing on saw blade for material being cut.
f. Too fast feed rate for material being cut and blade used.
4.7 BREAK-IN OPERATION:
When a new blade is used , be sure to first break in the blade before using it for extended operation.
Failure to break in the blade will shorten the service lift of the blade ,and result in less than optimum
efficiency. To break in the blade ,proceed as follow :
(1) Reduce the blade speed setting to one half of its normal setting .
(2) Lengthen the time required for cutting to 2-3 times that of normal.
(3) The break-in operation can be considered sufficient if all unusual noises or metallic sounds have
been eliminated. (For instance, to completely break in the blade, a minimum of five complete cuts
of a 200mm (8 ins) diameter work- piece will be required.)
(4) After the break-in operation has been completed, return the blade speed and feed rate to their
normal setting.
