NOTE
For quick response, Nexen recommends a quick exhaust
valve and short air lines between the Control Valves and
the product. Align the air inlet ports to a down position
to allow condensation to drain out of the air chambers
of the product.
CAUTION
Low air pressure will cause slippage and
overheating. Excessive air pressure will
cause abrupt starts and stops, reducing
product life.
