GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. Cluttered benches and dark areas
invite accidents.
Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power tools create
sparks which may ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as blown dirt, rocks, sticks, etc. Provide barriers or shields as need-
ed.
ELECTRICAL SAFETY
Grounded tools must be plugged into an outlet properly installed and
grounded in accordance with all codes and ordinances. Never remove the

grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically malfunction or
break down, grounding provides a low resistance path to carry electricity away
from the user.
Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
PERSONAL SAFETY
Stay alert. Watch what you are doing, and use common sense when
operating a power tool. Do not use a power tool while tired or under the
influence of drugs, alcohol, or medication. A moment of inattention while
operating power tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in moving parts.
Do not overreach. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the power tool in unexpected situa-
tions.
Always wear ANSI-approved safety impact goggles when using this
product. Dust mask, nonskid safety shoes, and a hard hat must be used
for appropriate conditions.
Noise precautions: Prolonged exposure to noise levels above 85 dBA is
hazardous to hearing. Always wear ANSI-approved hearing protection when
operating or working around the Blower when it is running.
TOOL USE AND CARE
Do not force the tool. Use the correct tool for your application. The correct
tool will do the job better and safer at the rate for which it is designed.
Do not use the Blower if the Power Switch does not turn it on or off. Any
tool that cannot be controlled with the Power Switch is dangerous and must be
replaced.
Turn off the Power Switch and disconnect the AC/DC Adapter from the
electrical outlet before making any adjustments, changing accessories, or
storing the Blower. Such preventive safety measures reduce the risk of starting
the tool accidentally.

Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
Maintain tools with care. Keep the Blower clean and in proper working
order. Properly maintained tools with a sharp cutting edge are less likely to bind
and are easier to control. Do not use a damaged tool. Tag damaged tools “Do
not use” until repaired.
Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool’s operation. If damaged, have
the tool serviced before using. Many accidents are caused by poorly main-
tained tools.
Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous
when used on another tool.
SERVICE
Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow in-
structions in the “Inspection, Maintenance, And Cleaning” section of this
manual. Use of unauthorized parts or failure to follow maintenance instructions
may create a risk of electric shock or injury.

The charge time for the Battery (3) is from 10 to 12 hours. Do not charge the
Battery for over 12 hours as damage to the Battery and/or Blower may result.
Always switch to a fresh Battery (3) when tool performance begins to di-
minish. Severe heat is most destructive to a Battery. The more heat generated,
the faster the Battery loses its power. A Battery that gets too hot can be perma-
nently damaged. Never over-discharge a Battery by using the tool even after
tool performance is decreasing. Never attempt to discharge a tool’s Battery by
leaving the Power Switch on. When tool performance begins to diminish stop the
tool, recharge the Battery, and use the fresh Battery for optimal performance.
Battery (3) leakage may occur under extreme usage or temperature condi-
tions. Do not attempt to charge a leaking Battery. If Battery fluid comes
in contact with skin, wash with soap and water and rinse with lemon juice and
vinegar. If the fluid comes into contact with eyes, flush with water for several min-
utes and contact a physician immediately.
Never burn a Battery, as it can explode in a fire. Contact local solid
waste authorities for instructions on correct disposal of a Battery.
Do not operate the Blower without its Blower Tube (11) attached.
Do not operate the Blower while it is attached to the AC/DC Adapter (20).
Do not operate the Blower indoors.
WARNING! People with pacemakers should consult their physician(s) before
using this product. Operation of electrical equipment in close proximity to a heart
pacemaker could cause interference or failure of the pacemaker.
WARNING! The warnings and cautions discussed in this manual cannot
cover all possible conditions and situations that may occur. It must be under-
stood by the operator that common sense and caution are factors which cannot
be built into this product, but must be supplied by the operator.

DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
Tools marked “Double Insulated” do not require grounding. They have a special
double insulation system which satisfies OSHA requirements and complies with
the applicable standards of Underwriters Laboratories, Inc., the Canadian Stan-
dard Association, and the National Electrical Code. (See Figure A.)
Double insulated tools may be used in either of the 120 volt outlets shown in the
following illustration. (See Figure A.)

EXTENSION CORDS
Grounded tools require a three wire extension cord. Double Insulated tools can
use either a two or three wire extension cord.
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 Figure B, next page.)
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.
(See Figure B.)
When using more than one extension cord to make up the total length, make sure
each cord contains at least the minimum wire size required. (See Figure B.)
If you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size.
(See Figure B.)

If you are using an extension cord outdoors, make sure it is marked with the suf-
fix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified elec-
trician before using it.
Protect your extension cords from sharp objects, excessive heat, and damp or
wet areas.
