IMPORTANT SAFETY
INSTRUCTIONS
INSTRUCTIONS PERTAINING
TO A RISK OF FIRE,
ELECTRIC SHOCK, OR
INJURY TO PERSONS
WARNING – When using tools, basic
precautions should always be
followed, including the following:
General
a. To reduce the risks of electric
shock, re, and injury to persons,
read all the instructions before
using the tool.
Work area
a. Keep the work area clean and well
lighted. Cluttered benches and dark
areas increase the risks of electric
shock, re, and injury to persons.
b. Keep bystanders, children, and
visitors away while operating the
tool. Distractions are able to result in
the loss of control of the tool.
Personal safety
a. Stay alert. Watch what you are
doing and use common sense
Page 3For technical questions, please call 1-800-444-3353.SKU 33615
when operating the tool. Do not
use the tool while tired or under
the inuence of drugs, alcohol, or
medication. A moment of inattention
while operating the tool increases the
risk of injury to persons.
b. Dress properly. Do not wear loose
clothing or jewelry. Contain long
hair. Keep hair, clothing, and
gloves away from moving parts.
Loose clothes, jewelry, or long hair
increases the risk of injury to persons
as a result of being caught in moving
parts.
c. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance
enables better control of the tool in
unexpected situations.
d. Use safety equipment. A
dust mask, non-skid safety
shoes and a hard hat must
be used for the applicable
conditions. Wear heavy-duty work
gloves during use.
e. Always wear eye
protection. Wear ANSI-
approved safety goggles.
Tool use and care
a. Do not force the tool. Use the
correct tool for the application. The
correct tool will do the job better and
safer at the rate for which the tool is
designed.
b. Disconnect the tool from the
air source before making
any adjustments, changing
accessories, or storing the tool.
Such preventive safety measures
reduce the risk of starting the tool
unintentionally. Turn off and detach
the air supply, safely discharge any
residual air pressure, and release the
throttle and/or turn the switch to its off
position before leaving the work area.
c. Store the tool when it is idle out
of reach of children and other
untrained persons. A tool is
dangerous in the hands of untrained
users.
d. Maintain the tool with care. Keep
a cutting tool sharp and clean. A
properly maintained tool, with sharp
cutting edges reduces the risk of
binding and is easier to control.
e. 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.
f. Use only accessories that are
identied by the manufacturer for
the specic tool model. Use of an
accessory not intended for use with
the specic tool model, increases the
risk of injury to persons.
Service
a. Tool service must be performed
only by qualied repair personnel.
b. When servicing a tool, use only
identical replacement parts. Use
only authorized parts.
c. Use only the lubricants supplied
with the tool or specied by the
manufacturer.
