mask/respirator. Safety equipment
such as non-skid safety shoes, hard
hat, or hearing protection used for
appropriate conditions will reduce
personal injuries.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b.Avoid body contact with grounded
surfaces such as pipes, radiators,
ranges and refrigerators. There is
an increased risk of electric shock if
your body is grounded.
c.Prevent unintentional starting.
Ensure the Power Switch (33) is in
the off-position before connecting
to the power source, picking up or
carrying the tool. Carrying power
tools with your finger on the Power
Switch or energizing power tools that
have the Power Switch on invites accidents.
c.Do not expose power tools to rain
or wet conditions. Water entering
a power tool will increase the risk of
electric shock.
d.Do not abuse the Power Cord (34).
Never use the Cord for carrying,
pulling or unplugging the power
tool. Keep Cord away from heat,
oil, sharp edges or moving parts.
Damaged or entangled Cords increase the risk of electric shock.
d.Remove any adjusting key or
wrench before turning the power
tool on. A wrench or a key left attached to a rotating part of the power
tool may result in personal injury.
e.When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the
risk of electric shock.
e.Do not overreach. Keep proper
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
f. Dress properly. Do not wear loose
clothing or jewelry. Keep your
hair, clothing and gloves away
from moving parts. Loose clothes,
jewelry or long hair can be caught in
moving parts.
f. If operating a power tool in a damp
location is unavoidable, use a
Ground Fault Circuit Interrupter
(GFCI) protected supply. Use of
a GFCI reduces the risk of electric
shock.
3.
Personal safety
a.Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use
a power tool while you are tired
or under the influence of drugs,
alcohol or medication. A moment
of inattention while operating power
tools may result in serious personal
injury.
b.Use safety equipment. Always
wear ANSI-approved safety impact
goggles and NIOSH-approved dust
SKU 97750
4.
Power tool use and care
a.Do not force the power tool. Use
the correct power tool for your application. The correct power tool will
do the job better and safer at the rate
for which it was designed.
b.Do not use the power tool if the
Power Switch (33) does not turn
it on and off. Any power tool that
cannot be controlled with the Power
Switch is dangerous and must be
repaired.
For technical questions, please call 1-800-444-3353.
Page 3
c.Disconnect the Power Cord (34)
from the power source before making any adjustments, changing accessories, or storing power tools.
Such preventive safety measures
reduce the risk of starting the power
tool accidentally.
d.Store idle power tools out of the
reach of children and do not allow
persons unfamiliar with the power
tool or these instructions to operate the power tool. Power tools are
dangerous in the hands of untrained
users.
e.Maintain power tools. Check for
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool’s operation. If damaged, have the power tool repaired
before use. Many accidents are
caused by poorly maintained power
tools.
f. Keep the power tool clean. Improper cleaning of the Paint Sprayer and
its accessories is a common reason
for the Spray Gun to jam or not perform properly.
g.Use the power tool, accessories
and tool bits etc. in accordance
with these instructions, taking into
account the working conditions
and the work to be performed. Use
of the power tool for operations different from those intended could result
in a hazardous situation.
5.
Service
a.Have your power tool serviced by
a qualified repair person using
only identical replacement parts.
This will ensure that the safety of the
power tool is maintained.

As the distance from the supply outlet
increases, you must use a heavier
gauge extension cord. Using extension cords with inadequately sized
wire causes a serious drop in voltage,
resulting in loss of power and possible tool damage.
(See Table A.) The smaller the
gauge number of the wire, the greater
the capacity of the cord. For example, a 14 gauge cord can carry a
higher current than a 16 gauge cord.
