Ducting Guidelines

DANGER
Asphyxiation. Running engines produce carbon
monoxide, a colorless, odorless, poisonous
gas. Carbon monoxide, if not avoided, will
result in death or serious injury.
WARNING
Burn hazard. Do not remove ducting until all air
pressure has been emptied from hose duct.
Failure to do so could result in severe injury.
•
Place ducting in desired configuration before oper-
ating the unit.
•
Tightly secure ducting end to the unit. Verify any
additional ducting is also tightly secured.
•
Avoid sharp bends or 90° turns in the ducting.
•
Use only the necessary length of ducting required.
•
Verify that ducting is not in a high traffic area, and
will not impede workers or other machinery. Care
should be taken to prohibit the need to step or
climb over ducting.
•
DO NOT place ducting over combustible materials.
•
DO NOT place ducting over surfaces that may
cause damage or reduce performance, such as
water, sharp rocks or glass, electrical wiring, pip-
ing, etc.
•
DO NOT place or drape anything over ducting,
such as covers, insulation (insulated ducting is
available), blankets or cloth, or electrical wires.
•
Inspect ducting for damage or unusual wear before
each use.

WARNING
Hot Surfaces. When operating machine, do not
touch hot surfaces. Keep machine away from
combustibles during use. Hot surfaces could
result in severe burns or fire.
WARNING
Crushing hazard. Verify unit is properly secured and
on level ground. An unsecured unit can suddenly roll

CAUTION
Equipment or property damage. Do not block air
intake or restrict proper air flow. Doing so could
result in unsafe operation or damage to unit.
