B W MANUFACTURING, INC.
GENERAL SAFETY & HAZARDOUS MATERIALS WARNING
WARNING SURFACE PREPARATION EQUIPMENT CAN BE DANGEROUS IF NOT OPERATED
PROPERLY. THE OPERATOR IS RESPONSIBLE FOR THE SAFE OPERATION OF THIS EQUIPMENT.
The operator must carefully read and follow any warnings or safety instructions provided with the equipment
prior to operating the equipment. Do not remove any safety devices or warnings on the equipment.
WARNING FLOOR AND/OR DECK SURFACES MAY BE COATED WITH OR CONTAMINATED BY
HAZARDOUS MATERIALS. Typical examples of hazardous materials include (i) tile mastic (likely to contain
asbestos); (ii) stained areas near electrical equipment (potentially containing PCBS); (iii) paint (potentially con-
taining lead); (iv) stained floor areas in chemical or other industrial facilities (potentially containing toxic pesti-
cides, cleaning fluids, solvents, or other harmful chemicals).
WARNING Preparation equipment is used to remove surface material from a variety of surfaces. The surface
preparation process often generates large amounts of dust and other small particles, which are released into the
air. WHEN A SURFACE CONTAINS HAZARDOUS MATERIALS, EXPOSURE TO THE DUST GENER-
ATED BY THE PREPARATION EQUIPMENT MAY POSE A HEALTH RISK. INSPECT ALL SURFACES
FOR POSSIBLE CONTAMINATES PRIOR TO USING PREPARATION EQUIPMENT AND CONSULT
HAZARDOUS MATERIAL EXPERTS AND GOVERNMENT AUTHORITIES BEFORE OPERATING
PREPARATION EQUIPMENT ON SURFACES SUSPECTED OF CONTAINING HAZARDOUS MATERI-
ALS.
WARNING BW MANUFACTURING, INC. IN NO WAY REPRESENTS THAT ITS PREPARATION
EQUIPMENT IS SUITABLE OR APPROVED FOR REMOVING HAZARDOUS MATERIALS FROM CON-
TAMINATED SURFACES. DO NOT ATTEMPT TO USE ANY PREPARATION EQUIPMENT MANUFAC-
TURED BY BW MANUFACTURING, INC. ON ANY CONTAMINATED SURFACE. It is the responsibility
of the preparation equipment operator and/or the contractor using the preparation equipment to inspect the pro-
posed worksite for contaminates and obtain approval from contamination experts and/or government authorities
before using BW Manufacturing, Inc. preparation equipment. It is also the responsibility of any contractor using
preparation equipment to inform its employees or subcontractors of all potential health risks associated with op-
erating preparation equipment and to ensure its employees or subcontractors are protected from exposure to
harmful materials.
BW MANUFACTURING, INC. IS NOT RESPONSIBLE FOR ANY INJURY, ILLNESS, DEATH, OR PROP-
ERTY DAMAGE THAT MAY RESULT FROM IMPROPER USE OF ITS PREPARATION EQUIPMENT OR
OTHER PRODUCTS

Filter Media Specifications
New filters may “puff”a minuscule amount dust for the first 10 to 15 minutes of use or until the
filter is adequately coated with material. The stock filter (10129-H) cleans to 99.7% efficiency at
0.3 micron directly out of the box, and the filter will therefore allow a minimal amount of dust
through the filter on every pulsation cycle.
Further tests have shown that humidity and concrete dampness will affect the efficiency of the pulsation
system to clean the filter.
#10129-H Spun Bond W/PTFE Coating (Standard Filter in all BW Manufacturing equipment):
· SpunBond P.T.F.E., 70 pleats, 31 Sq. Ft media.
· Efficiency of 99.7% @ 0.3 Microns (Minimum Efficiency Rating Value (MERV) 16 Rating - Out of the box)
#10129-B Cellulose Paper/Polyester Blend Filter (Optional Replacement Filter) :
· 80/20 Blend, 120 pleats, 53 Sq. Ft media.
· Efficiency of 99.9% @ 1.0 Micron with a seasoned ( caked ) filter.
Technical Notes:
· OSHA Standard#: 1926.1153 for Respirable crystalline silica requires a filter with 99.0% or greater efficiency.
· All values are averages
· Specifications are subject to change without notice
· To qualify as HEPA by US government standards, an air filter must remove (from the air that passes through) 99.97% of particles
that have a size of 0.3 µm*. HEPA was commercialized in the 1950s, and the original term became a registered trademark and later a
generic term for highly efficient filters. Products that claim to be "HEPA-type", "HEPA-like", "HEPA-style" or "99% HEPA" do not
satisfy these requirements and may not have been tested in independent laboratories. Some of these sub-par quality filters may come
reasonably close to HEPA filtration, while others will fall significantly short, making them truly inferior.
* The symbol µm or micrometer/micron is one thousand of a millimeter, 0.001mm or about 0.000039 inch

Test Results in accordance to
OSHA 1926.1153 Respirable Silica Dust Exposure
On October 27, 2017, an Industrial Hygienist with the Consultation Education and Training (CET) Division of the Michigan Occupational
Safety and Health Administration (MIOSHA) conducted air monitoring at our facility in response to our request for assistance with evalu-
ating employee exposures to silica while using BW Manufacturing’s grinders and vacuum.
The air monitoring included breathing zone samples on an employee using the DG-71-ME Hand Grinder connected to an A-101 Pulse Vac
and a DG-16-2 Diamond Grinder/Polisher connected to an A-101 Pulse Vac. These were screening samples that were run long enough to
ensure that the sample result’s limit of detection was below the established action level limit of 0.025 mg/m³.
Air Monitoring
The air sampling that was performed at our facility was only considered to be screening samples and do not represent a full shift monitor-
ing period. If these operations were consistently performed for the full shift, then the Sample Results, found on the enclosed Air Contami-
nant Data Sheets, would be a relatively accurate employee exposure representation for a full shift.
The test results revealed that the operator using both the DG-71-ME Hand Grinder and the DG-16-2 Diamond Grinder/Polisher was not
exposed to concentrations of respirable quartz (silica), respirable cristobalite and respirable nuisance dust in excess of the established lim-
its (i.e., PEL). The results indicated that silica was not detected on the filters.
These air sample results can be passed on as objective data to employers to utilize when developing their safety and health programs and
determining employee exposure levels. Contractors must be reminded that the working conditions must be similar to the test conditions if
this is going to be used as objective data. The testing was performed outdoors on concrete that contained 50% silica as determined through
a bulk sample submitted to the lab. This objective data would not be applicable to work conditions that contain more than 50% silica or is
performed indoors. Further testing (air monitoring) for indoor environments would be required for use as objective data indoors.

Filter Maintenance:
Never fill container above hose inlet (1).
This can cause debris to pack tight in the
filter.
For every 8 hours of running time, it is
recommended to remove the filter (2) and
clean manually.
To Clean Filter Manually:
Rotate the filter and gently tap the filter
sides on the ground. Adverse conditions
on the filters such as heavy grease, oil,
glues, and moisture may require more
frequent manual cleaning or replacement.
Periodically clean rear cooling filters (3).

TOADJUST PRESSURE SWITCH:
While checking pressure on gauge (1), adjust screw
(2) clockwise to raise pressure and counter clockwise
to lower pressure. Only adjust screw in 1/2 turn
increments and let the vacuum cycle. If pressure does
not raise, check for air leaks or a worn out
compressor. Pressure should reach between 80
and 90 pounds before cycling.

To determine if you have a bad dust filter.
Watch the indicator lights on the timer board and blower
exhaust while the machine is in operation. If a puff of dust
follows an indicator light, that filter is bad and should be
replaced. Or when inspecting filters you find a layer of dust
on the top of the filter inside the rubber seal ring, this is an
indication that the filter is bad and needs to be replaced. (Using filters that are not designed for collector
systems will cause a decrease in vacuum and
will reduce paddle and liner life).
Dust Filter Cleaning & Replacement.
To clean filter manually, rotate the filter and gently tap
the filter sides on the ground. Adverse conditions on the
filters such as heavy grease, oil, glues, and moisture may
require more frequent manual cleaning or replacement.

Maintenance Instructions
The 10129-B Filter on the left weighs over 2 lbs.
less then the competitors filter due to better air flow
during the pulsation process.
This is the 10129-B Filter
that is the stock filter in all
BW Manufacturing, Inc.
equipment. This is a competitors filter.
Both filters were installed in the same machine and you
can see that the filter on the right has more pleats along
with dust packed near the top rim.
