Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate dust, mists and fumes containing chemicals
known to cause serious or fatal injury or illness, such as respiratory disease, cancer, birth defects or other reproductive harm. If
you are unfamiliar with the risks associated with the particular process and/or material being cut or the composition of the tool being
used, review the material safety data sheets and/or consult your employer, the manufacturers/suppliers, governmental agencies
such as OSHA and NIOSH and other sources on hazardous materials. California and some other authorities, for instance, have
published lists of substances known to cause cancer, reproductive toxicity, or other harmful effects.
Control dust, mist and fumes at the source where possible. In this regard use good work practices and follow the recommendations of
the manufacturers/suppliers, OSHA/NIOSH, and occupational and trade associations. Water should be used for dust suppression
when wet grinding/cutting/drilling is feasible. When the hazards from inhalation of dust, mists and fumes cannot be eliminated,
the operator and any bystanders should always wear a respirator approved by NIOSH/MSHA for the material being used.
Grinding/cutting/drilling of masonry, concrete and other materials with silica in their composition may give off dust or mists containing
crystalline silica. Silica is a basic component of sand, quart�, brick clay, granite and numerous other minerals and rocks. Repeated
and/or substantial inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis. In
addition, California and some other authorities have listed respirable crystalline silica as a substance known to cause cancer.
When grinding/cutting/drilling such materials, always follow the respiratory precautions mentioned above.
SMI Dust and Silica Warning
Trouble Shooting VAC-290 & VAC-200
PROBLEM
Insuffi cient Vacuum
Pressure
Air Leaks
Material In Exhaust/
On Top Side of Filter
Unusual or High
Pitched Noises
POSSIBLE CAUSE
- Motors are not on and/or
working
- Dustpan improperly seated
- Filter clogged or improperly
seated
- Clogged hose
- Unit is improperly sealed
- Worn or poorly seated seals,
- Poor fi lter seal or torn
fi lter
- Motor bearings, Motor
brushes
- Worn or poorly seated seals,
Retainers improperly installed
CORRECTIVE ACTION
- Turn both motors on, check motor brushes
- Remove dustpan, inspect seal, replace dustpan.
- Follow fi lter inspection procedure, page 6.
- Remove hose and re-inspect vacuum pressure, if
vacuum pressure returns to normal snake hose.
- Block the inlet with a fl at and rigid material to
place the unit under vacuum pressure then
inspect for air leaks.
- Block the inlet with a fl at and rigid material to
place the unit under vacuum pressure then
remove retainers and turn the unit off. Inspect the
seals for completeness, then reseat and secure
components again under vacuum pressure.
- Follow fi lter inspection procedure in Inspection
and Maintenance section.
- Follow relevant motor brushes inspection proce-
dure in Inspection and Maintenance section.
Check motor bearings for noise by hand.
- Block the inlet with a fl at and rigid material to
place the unit under vacuum pressure then
remove retainers and turn the unit off. Inspect the
seals for damage, then reseat and secure
components again under vacuum pressure.
