risk of binding and is easier to control.
6. Check for misalignment or binding of moving
parts, breakage of parts, and any other condition
that affects the tool's operation. If damaged,
have the tool serviced before using. Many accidents
are caused by poorly maintained tools.
There is a risk of bursting if the tool is damaged.
7. Use only accessories that are identified by the
manufacturer for the specific tool model. Use of
an accessory not intended for use with the specific
tool model, increases the risk of injury to persons.
2. When servicing a tool, use only identical
replacement parts. Use only authorized parts.
Air Source
1. Never connect to an air source that is
capable of exceeding 200 psi.
Over pressurizing the tool may cause
bursting, abnormal operation, breakage
of the tool or serious injury to persons.
Use only clean, dry, regulated compressed air at the
rated pressure or within the rated pressure range as
marked on the tool. Always verify prior to using the
tool that the air source has been adjusted to the rated
air pressure or within the rated air-pressure range.
SAVE THESE INSTRUCTIONS.
2. Never use oxygen, carbon dioxide, combustible
gases or any bottled gas as an air source
for the tool. Such gases are capable of
explosion and serious injury to persons.

Silicosis and Aluminum Oxide Warnings
WARNING! Abrasive blasting with sand containing crystalline silica can cause serious or fatal respiratory disease.
Exposure to crystalline silica may cause silicosis (a serious lung disease), cancer and death. Exposure to aluminum
oxide (a dust generated from material removing processes) can result in eye, skin and breathing irritation. Always
use a NIOSH (National Institute for Occupational Safety and Health) approved respirator and safety goggles. Avoid
SAFETY OPERATION MAINTENANCESETUP
skin exposure. Proper ventilation in the work area is required. Read and understand the 10 recommended measures
below to reduce crystalline silica exposures in the workplace and prevent silicosis and silicosis related deaths.
NIOSH recommends the following measures to reduce crystalline silica exposures
in the workplace and prevent silicosis and silicosis-related deaths:
1. Prohibit silica sand (or other substances
containing more than 1% crystalline silica)
as an abrasive blasting material and
substitute less hazardous materials.
2. Conduct air monitoring to measure worker exposures.
3. Use containment methods such as blast-cleaning
machines and cabinets to control the hazard
and protect adjacent workers from exposure.
4. Practice good personal hygiene to avoid
unnecessary exposure to silica dust.
5. Wear washable or disposable protective clothes
at the work site. Shower and change into clean
clothes before leaving the work site to prevent
contamination of cars, homes and other work areas.
6. Use respiratory protection when source controls
cannot keep silica exposures below the NIOSH REL.
7. Provide periodic medical examinations for all
workers who may be exposed to crystalline silica.
8. Post signs to warn workers about the hazard and to
inform them about required protective equipment.
9. Provide workers with training that includes
information about health effects, work practices
and protective equipment for crystalline silica.
10. Report all cases of silicosis to State health
departments and to OSHA or the Mine Safety
and Health Administration (MSHA).
Vibration Precautions
This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical check-ups to
ensure medical problems are not being caused or
worsened from use. Pregnant women or people who
have impaired blood circulation to the hand, past
hand injuries, nervous system disorders, diabetes,
or Raynaud's Disease should not use this tool.
If you feel any symptoms related to vibration (such
as tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
7. To reduce vibration, maintain
tool as explained in this manual.
If abnormal vibration occurs, stop immediately.
