General Power Tool Safety Information
WARNING
Read all safety warnings and all
instructions.
Failure to follow the warnings and instructions
mayresultin electric shock, fireand/or serious
injury.
Save all warnings and instructions for
future reference.
The term “power tool” in the warnings refers to
your mains-operated (corded) power tool.
Work Area Safety
•Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
•Donotoperatepowertoolsinexplosive
atmospheres, such as in the presence
of flammable liquids, gases or dust.
Power tools create sparks which may
ignite the dust or fumes.
•Keep children and bystanders away
while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
•Powertoolplugsmustmatchtheoutlet.
Never modify the plug in any way. Do
not use any adapter plugs with earthed
(grounded) power tools. Unmodified
plugsandmatchingoutlets will reducerisk

•Avoid body contact with earthed or
grounded surfaces, such as pipes,
radiators, ranges and refrigerators.
Thereisanincreasedriskofelectricshock
if your body is earthed or grounded.
•Donotexposepowertoolstorainorwet
conditions. Water entering a power tool
will increase the risk of electric shock.
•Do not abuse the cord. Never use the
cordforcarrying,pullingorunplugging
the power tool. Keep cord away from
heat, oil, sharp edges or moving parts.
Damaged or entangled cords increasethe
risk of electric shock.
•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.
•If operating a power tool in a damp
location is unavoidable, use a residual
current device (RCD) protected supply.
Use of an RCD reduces the risk of electric
shock.
Personal Safety
•Stay alert, watch what you are doing
andusecommonsensewhenoperating
a power tool. Do not use a power tool
while you are tired or under the
influence of drugs, alcohol or
medication.Amomentofinattentionwhile
operatingpowertoolsmayresultinserious
personal injury.
•Use personal protective equipment.
Always wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing
protection used for appropriate conditions
will reduce personal injuries.
•Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to power source and/or
battery pack, picking up or carrying the
tool. Carrying power tools with your finger
ontheswitchorenergizingpowertoolsthat
have the switch on invites accidents.
•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.
•Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in
unexpected situations.
•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.
•If devices are provided for the
connection of dust extraction and
collection facilities, ensure these are
connected and properly used. Use of
dust collection can reduce dust-related
hazards.

How to Spray
Take a few moments prior to spraying and
review these simple tips to ensure your
spraying project is a success.
Dual Speed Control
(Not available on all units)
The dual speed control feature allows you to
slow down or speed up when spraying.
•Turn the dual speed control to LOW to
slowdownthespeedofapplicationwhen
first learning to spray or when spraying
small items that require more control.
•The LOW setting delivers more control
andwillreduceoverspraywhenspraying
thinner materials such as stain.
•Turn the dual speed control to HIGH
whenyouwanttogettojobdonefastand
when spraying large surfaces.
•To reduce overspray, always spray at
lowest speed that results in an
acceptable spray pattern.
Variable Speed Control
(Not available on all units)
Thevariablespeedcontrolfeatureallowsyou
infinite speed control to slow down or speed
up to best suit your material and project.
•Turn the variable speed control to lower
speedsettingstoslowdownthespeedof
applicationwhenfirstlearningtosprayor
when spraying small items that require
more control.
•The lower speed settings deliver more
control and will reduce overspray when
spraying thinner materials such as stain.
•Turnthevariablespeedcontroltohigher
speedsettings when you want to getthe
job done fast and when spraying large
surfaces.
•To reduce overspray, always start at
lowestspeedsettingandincreasespeed
to the minimum setting that results in an
acceptable spray pattern.
Spray Techniques
Use a piece of scrap cardboard to practice
these basic spraying techniques before you
begin spraying the surface.
•Holdsprayer10in.(25cm)fromsurface
and aim straight at surface. Tilting the
sprayer to direct thespray angle causes
an uneven finish.
•Flex wrist to keep sprayer pointed
straight. Fanning sprayer to direct spray
at angle causes uneven finish.
NOTE: How fast you move the sprayer will
affect spray application. If material is
pulsating,youaremoving too fast.Ifmaterial
drips, you are moving too slow. See
