WARNING
Risk of injection or injury – Do not direct discharge stream at people or animals.
EXTENSION CORDS
• When using a power tool at a considerable distance from a power source, be sure to use
an extension cord that has the capacity to handle the current the product will draw. An
undersized cord will cause a drop in line voltage, possibly resulting in overheating, loss
,7'3,8"!.'0)12,!'1090:"'&,'*(!*$(&';!"0-"!6 Use the chart to determine the minimum
wire size required in an extension cord. Only round jacketed cords listed by Underwriter’s
Laboratories (UL) should be used. When working outdoors with a product, use an extension
cord that is designed for outside use. This type of cord is designated with “WA” or “W” on
the cord’s jacket. Before using any extension cord, inspect it for loose or exposed wires and
cut or worn insulation. It is possible to tie the extension cord and power cord in a knot to
prevent them from becoming disconnected during use. Make a knot, then connect the plug
end of the power cord into the receptacle end of the extension cord. This method can also
be used to tie two extension cords together.
USE ONLY THIS SIZE ENTENSION CORD WHEN USING THIS PRODUCT:

50 ft. Not Allowed
100 ft. Not Allowed
WARNING
To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch
plug with wet hands.
WARNING
Check extension cords before each use. If damaged, replace immediately. Never use the product
with a damaged cord since touching the damaged area could cause electrical shock, resulting in
serious injury.

SAFETY INFORMATION
WARNING
Keep the extension cord clear of the working area. Position the cord so that it will not get caught
on lumber, tools, or other obstructions while you are working with a power tool. Failure to do so
can result in serious personal injury.
• Know your product. Read the operator’s manual carefully. Learn the machine’s applications
./$(3,9,'.',#/)7(.)(2+33(.)('1+()*+&,-&(*#'+/',.3(1.<."$)("+3.'+$('#('1,)(*"#$%&':
• To reduce the risk of injury, keep children and visitors away. All visitors should wear safety
glasses and be kept a safe distance from the work area.
• Use the right product for the job. Don’t force the product or the attachments to do a job it was
not designed for. Don’t use it for a purpose not intended.
• Dress properly. Do not wear loose clothing, gloves, neckties, or jewelry. They can get caught

when working outdoors. Also wear protective hair covering to contain long hair.
• Do not operate the equipment while barefoot or when wearing sandals or similar lightweight
footwear. Wear protective footwear that will protect your feet and improve your footing on
slippery surfaces.
• Exercise caution to avoid slipping or falling.
• Always wear eye protection with side shields marked to comply with ANSI Z87.1. Following
this rule will reduce the risk of serious personal injury.
• Use only recommended accessories. The use of improper accessories may cause risk of
injury.
• Check damaged parts. Before further use of the product, all parts should be carefully checked
to determine that they will operate properly and perform their intended function. Check for
alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any
other conditions that may affect its operation. A guard or other part that is damaged must be
properly repaired or replaced by an authorized service center to avoid risk of personal injury.
• Never leave product running unattended. Turn power off. Do not leave the product until it
