Hoses - The connection from the air supply system piping to the hoist must be
made with a flexible pressure hose. Due to normal line losses in air supply lines:
„ Do not use hose smaller than specified in Table 3-1 , and
„ Limit the length of the hose to that specified in Figure 3-3 .
If your application exceeds these requirements consult factory.

CAUTION
Fittings - Important considerations regarding fittings in the hoist's air supply
include:
„ When connecting air supply components, remove all dirt or debris from the connecting surfaces of
the hoses, pipes, fittings, or threaded fasteners to prevent contaminants from entering the hoist.
„ Keep airflow restrictions such as quick disconnect fittings, bends, elbows, and adapters to a
minimum.
