Masonry drilling on materials such as
concrete (which contains crystalline silica)
can cause silicosis (a serious lung disease),
cancer and death. To reduce crystalline silica
exposures in the workplace and prevent
silicosis and silicosis-related deaths:
a. Conduct air monitoring to measure
worker exposures.
b. Use containment methods to control the hazard
and protect adjacent workers from exposure.
c. Practice good personal hygiene to avoid
unnecessary exposure to silica dust.
d. 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. Avoid skin exposure.
e. Always wear a NIOSH approved respirator and
safety goggles. Ventilate the work area properly.
f. Provide periodic medical examinations for all
workers who may be exposed to crystalline silica.
g. Post signs to warn workers about
the hazard and to inform them about
required protective equipment.
h. Provide workers with training that includes
information about health effects, work practices
and protective equipment for crystalline silica.
i. Report all cases of silicosis to State health
departments and to OSHA or the Mine
Safety and Health Administration (MSHA).

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:
a. 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.
b. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
c. Wear suitable gloves to reduce the
vibration effects on the user.
d. Use tools with the lowest vibration
when there is a choice.
e. Include vibration-free periods each day of work.
f. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
g. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.

and rotate the Mode Selector until it clicks in place
with the Indicator pointing to the desired function.

Motor is stopped. Attempting to move the Mode
Selector while the Motor is engaged will result in
abrupt bit rotation and can cause property damage.

make sure it clicks into the desired position. If
not locked in place, the Mode Selector could

OFPGLIMg Wear heavy-duty work gloves to
provide protection when inserting and removing
drill bits. Drill bits become very hot during use.
Do not remove drill bits until the bit has cooled.
Do not strike stuck bits with a hammer.
1. Grease the drill bit shank before installing.
2. Pull back on the Chuck and insert the drill bit.
Make sure it slides all the way into the opening.
3. Release the Chuck.
4. Check that the drill bit is secured in place.
It should not be able to be pulled out of the Chuck.
M&$*- When drilling a hole larger than 1-1/4 diameter,
use a drill bit with four cutting edges.

1. Designate a work area that is clean and well-
lit. The work area must not allow access by
children or pets to prevent distraction and injury.
2. Route the power cord along a safe route to reach
the work area without creating a tripping hazard or
exposing the power cord to possible damage. The
power cord must reach the work area with enough
extra length to allow free movement while working.
3. Secure loose work pieces using a vise or clamps
(not included) to prevent movement while working.
4. There must not be objects, such as utility lines,
nearby that will present a hazard while working.
