NOTE: Motors used on wood-working tools are
particularly susceptible to the accumulation of
sawdust and wood chips and should be blown outor
"vacuumed' frequently to prevent interference with
normal motor ventilation.
NOTE: The starting relay is a GRAVITY SENSITIVE
TYPE. NEVER TURN THE POWER ON WHILE THE
SAW IS UPSIDE DOWN AS THIS WILL DAMAGE
THE MOTOR.
