Extension Cords
Use a sufficient gauge:
Up to 25 ft. = 12/3 AWG.
25 to 50 ft. =10/3 AWG.
Use only extension cords that are intended
for outdoor use. These extension cords are
identified by a marking “Acceptable for use

cords. Examine extension cord before using
and replace if damaged. Do not abuse extension cord and do not yank on any cord to disconnect. Keep cord away from heat and sharp
edges. Always disconnect the extension cord
from the receptacle before disconnecting the
product from the extension cord. If you are
using an extension cord, it should always be
completely unwound from the cable drum.
Grounding Instructions
This product must be grounded. If it should
malfunction or breakdown, grounding
provides a path of least resistance for
electric current to reduce the risk of electric
shock. This product is equipped with a cord
having an equipment-grounding conductor
and a grounding plug. The plug must be
plugged into an appropriate outlet that is
properly installed and grounded in accordance with all local codes and ordinances.
DANGER- Improper connection of the
equipment-grounding conductor can result in
a risk of electrocution. Check with a qualified
electrician or service personnel if you are in
doubt as to whether the outlet is properly
grounded. Do not modify the plug provided
with the product - if it will not fit the outlet,
have a proper outlet installed by a qualified
electrician. Do not use any type of adapter
with this product.
Caution
• Follow the maintenance instructions
specified in the manual.
• This machine has been designed for
use with cleaning detergent supplied
or recommended by the manufacturer.
The use of other cleaning detergents
may affect the operation of the
machine and void the warranty.
