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.

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.
