8. Check damaged parts. Before further use of the
machine, a guard or other part that is damaged
should be carefully checked to determine that it
will operate properly and perform its intended
function. Check for alignment of moving parts,
binding of moving parts, breakage of parts,
mounting and any other conditions that may
affect its operation. A guard or other part that is
damaged should be properly repaired or
replaced.
9. Make your workshop child proof with padlocks,
master switches or by removing safety keys.
10. Use recommended accessories; improper
accessories may be hazardous.
11. Do not place this unit on an unstable surface, or
where there is a risk of tipping over. Serious
injury could occur if the unit tips over.
12. Do not use this air filtration unit with a damaged

should, has been dropped, damaged, left
outdoors, or dropped into water, return it to a
service center.
13. If ceiling mounted, bottom of filtration unit must
be at least 7 feet from the floor.
14. If ceiling mounted, mounts must be anchored to
building structure which will support the weight
of the air filtration unit. Never mount to surfaces
such as dry wall or false ceiling grids.
15. To reduce risk of electric shock, do not expose
filtration unit to water or rain.
16. Never duct a machine directly into the air
filtration unit.
17. To avoid a potentially dangerous situation, do
not use this equipment to filter volatile fumes or
smoke.
18. Do not use this unit in high humidity
environments. Doing so may cause electric
shock and/or decreased performance of the
unit.
19. Do not use this equipment to filter flammable
vapors. This air filtration unit is designed and
intended for the filtration of air borne dust only.

purpose whatsoever. If used for other purposes,
Powermatic disclaims any real or implied
warranty and holds itself harmless from any
injury that may result from that use.
20. This product complies with the maximum
allowable concentration of ozone of 0.050 parts
per million by volume (ppmv) in a 24-hour
period. The Health Canada Guideline 2010
recommends that the maximum exposure limit,
based on an averaging time of 8 hours, is 0.020
ppmv or less when tested in a sealed, controlled
room approximately 30 m3.
WARNING: This product can expose you to
chemicals including nickel which is known to the
State of California to cause cancer, and lead
which is known to the State of California to cause

Familiarize yourself with the following safety notices used in this manual:
This means that if precautions are not heeded, it may result in minor injury and/or possible
machine damage.
This means that if precautions are not heeded, it may result in serious or possibly fatal injury.
WARNING: Some dust, fumes and gases created by power sanding, sawing, grinding, drilling, welding and
other construction activities contain chemicals known to the State of California to cause cancer and birth
defects or other reproductive harm. Some examples of these chemicals are:
•lead from lead based paint
