sive atmospheres, such as in the
presence of ammable liquids,
gases, or dust. The tool is able to
create sparks resulting in the ignition
of the dust or fumes.
e. 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.
Keep bystanders, children, and c.
visitors away while operating the
tool. Distractions are able to result in
the loss of control of the tool.
Personal safety
Stay alert. Watch what you are do-a.
ing and use common sense 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.
Dress properly. Do not wear loose b.
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.
Avoid unintentional starting. Be c.
sure the switch is off before connecting to the air supply. Do not
carry the tool with your nger on the
switch or connect the tool to the air
supply with the switch on.

cutting tool sharp and clean. A properly maintained tool, with sharp cutting edges reduces the risk of binding
and is easier to control.
Check for misalignment or bind-g.
ing of moving parts, breakage of
parts, and any other condition that
affects the tool’s operation. If dam-
aged, 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.
Use only the lubricants supplied c.
with the tool or specied by the
manufacturer.
Air source
a. 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.
Never use oxygen, carbon dioxide, b.
combustible gases or any bottled
gas as an air source for the tool.
Such gases are capable of explosion
and serious injury to persons.
SAVE THESE
INSTRUCTIONS.
Use only accessories that are h.
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.

INJURY FROM ACCIDENTAL
OPERATION:
Do not install a female quick
coupler on the tool. Such a coupler
contains an air valve that will allow
the air tool to retain pressure and
operate accidentally after the air
supply is disconnected.
Note: Air ow, and therefore tool perfor-
mance, can be hindered by undersized air supply components.
The air hose must be long enough 3.
to reach the work area with enough
extra length to allow free movement
while working.
Inspect the air connections for leaks. 8.
Repair any leaks found.
If the tool will not be used at this 9.
time, 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 to prevent accidental operation.
Note: Residual air pressure should not be
present after the tool is disconnected
from the air supply. However, it is a
good safety measure to attempt to
discharge the tool in a safe fashion
after disconnecting to ensure that the
tool is disconnected and unpowered.
Make sure the tool’s throttle or switch 4.
is in the off position; refer to Operation section for description of controls.
