WARNING! Some dust created by 
power sanding, sawing, grinding, drilling 
and other construction activities contains 
chemicals known to the state of California 
to cause cancer, birth defects or other 
reproductive harm. Some examples of these 
chemicals are:
•   Lead from lead-based paints,
•   Crystalline silica from bricks and cement 
and other masonry products, and
•   Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies, 
depending on how often you do this type 
of work. To reduce your exposure to these 
chemical:
•   Work in a well ventilated area,
•   Work with approved safety equipment, 
such as those dust masks that are specially 
designed to filter out microscopic particles.
IMPORTANT SAFETY INSTRUCTIONS
WARNING! When using electric 
gardening appliances, basic safety 
precautions must always be followed to 
reduce the risk of fire, electric shock, and 
serious injury, including the following:
WARNING: READ ALL 
INSTRUCTIONS.
1. FOR ALL DOUBLE- INSULATED 
APPLIANCES
a) Replacement parts. When servicing use 
only identical replacement parts.
b) Polarized appliance connections. 
To reduce the risk of electric shock, this 
appliance has a polarized plug (one blade 
is wider than the other) and will require 
the use of a polarized extension cord. 
The appliance plug will fit into a polarized 
extension cord only one way. If the plug 
does not fit fully into the extension cord, 
reverse the plug. If the plug still does not fit, 
obtain a correct polarized extension cord. 
A polarized extension cord will require the 
use of a polarized wall outlet. This plug will 
fit into the polarized wall outlet only one 
way. If the plug does not fit fully into the 
wall outlet, reverse the plug. If the plug still 
does not fit, contact a qualified electrician 
to install the proper wall outlet. Do not 
change the equipment plug, extension cord 
receptacle, or extension cord plug in any 
way.
2. FOR ALL APPLIANCES
a) Avoid dangerous environment. Don’t 
use appliances in damp or wet locations. 
b) Don’t use in rain. 
c) Keep children away. All visitors should 
be kept at a distance from work area. 
d) Dress properly. Do not wear loose 
clothing or jewelry. They can be caught in 
moving parts. Use of protective gloves and 
substantial footwear is recommended when 
working outdoors. Wear protective hair 
covering to contain long hair.
e)  Use safety glasses. Always use face or 
dust mask if operation is dusty. 
f)  Use right appliance. Do not use 
appliance for any job except that for which 
it is intended.
g)  Ground Fault Circuit Interrupter (GFCI) 
protection should be provided on the 
circuit(s) or outlet(s) to be used for the 
gardening appliance. Receptacles are 
available having built-in GFCI protection 
and may be used for an added measure of 
safety.
h)  WARNING! To reduce the risk of 
electric shock, use only with an 
extension cord intended for outdoor use, 
such as an extension cord of cord type 
SW-A, SOW-A, STW-A, STOW-A, SJW-A, 
SJOW-A, SJTW-A. or SJTOW-A.
i)  Extension cord! Make sure your extension 
cord is in good condition. When using an 
extension cord, be sure to use one heavy 
enough to carry the current your product 
will draw. An undersized extension cord 
will cause a drop in line voltage resulting 
in loss of power and overheating. Table 1 
shows the correct size to use depending on 
cord length and nameplate ampere rating. 
If in doubt, use the next heavier gage. The 
smaller the gage number, the heavier the 
cord. To reduce the risk of disconnection 
of appliance cord from the extension cord 
during operating:
i)   Make a knot as shown in Figure 1
ii)  Use one of the plug-receptacle retaining 
straps or connectors described in this 
manual.
