until "READY" light illuminates. While maintaining pressure on "Charge"
switch depress "DETONATE" switch. "READY" light should go off immediately.

The L450-4J utilizes a dual switch firing mechanism to assure the blaster's
conviction to detonate.

When "READY" light fails to illuminate replace the 9V Alkaline
Cell under battery cap on right side of machine. Observe cap position when
replacing cap so as not to cross thread.

TO OPERATE: Connect machine to the blasting circuit and repeat "CHARGE"
and "DETONATE" sequence as in "TO TEST."
