approved safety equipment, such as dust masks that are
specially designed to lter out microscopic particles.
Double-Insulated Appliances
In a double-insulated appliance, two systems of insulation
are provided instead of grounding. No grounding means
that it is already provided on a double-insulated appliance.
Servicing a double-insulated appliance requires extreme care
and knowledge of the system, and should be performed only
by qualied service personnel at an authorized Snow Joe
Sun Joe
dealer. Replacement parts for a double-insulated
appliance must be identical to the parts they replace. A
double-insulated appliance is marked with the words “Double
Insulation” or “Double Insulated.” The symbol (square
within a square) may also be marked on the appliance.
This electric scarier + dethatcher is double-insulated,
eliminating the need for a separate grounding system. Use
only identical replacement parts. Read the instructions before
servicing double-insulated appliances. Use this electric
scarier + dethatcher only as described in this manual.
Electrical Safety
1. Ground fault circuit interrupter (GFCI) protection should
be provided on the circuit(s) or outlet(s) to be used for
this electric scarier + dethatcher. Receptacles are
available having built-in GFCI protection and may be used
for this measure of safety.
2. To prevent electric shock, use only with an extension cord
suitable for outdoor use, such as SW-A, SOW-A, STW-A,
Before use, check that the extension cord is in good
condition. When using an extension cord, make sure to
use one heavy enough to carry the current your product
will draw. For lengths more than 50 ft (15 m), a No.14
AWG (or greater) extension cord should be used. An
undersized cord will cause a drop in line voltage resulting
in loss of power and overheating.
3. To reduce the risk of electric shock, this appliance has
a polarized plug (i.e. one blade is wider than the other).
Use this appliance only with a polarized UL-, CSA-, or
ETL-listed extension cord recommended for outdoor,
all-weather use, such as the Snow Joe
+ Sun Joe
Power Joe SJTW-A 14-gauge 50-foot extension cord
with lighted end (Model PJEXT50-B). Visit
to purchase this extension cord online or, to order by
phone, call 1-866-SNOWJOE (1-866-766-9563).
The appliance plug will t into a polarized extension cord
only one way. If the appliance plug does not t fully into the
extension cord, reverse the plug. If the plug still does not
t, obtain a correct polarized extension cord. A polarized
extension cord will require the use of a polarized wall outlet.
The extension cord plug will t into the polarized wall outlet
only one way. If the plug does not t fully into the wall
outlet, reverse the plug. If the plug still does not t, contact
a qualied electrician to install the proper wall outlet. Do not
modify the appliance plug, extension cord receptacle, or
extension cord plug in any way.

Circle around ower beds. When reaching a ower bed
in the middle of the lawn, make a row or two around the
circumference of the bed.
Pay special attention when changing direction.
Consider the weather when scarifying. Scarify the lawn with an
increased depth setting during spring time between April and
May as the lawn is better able to recover during this season.
During a wet summer scarify again in late summer with a
decreased depth setting. Do not scarify during periods of hot
weather condition. During a dry rainless summer do not scarify
a second time in autumn.
In order for a healthy lawn to develop in the spring, it is
necessary for greater amounts of air to penetrate the area
around the roots of the grass. We recommend aerating the
lawn every 4 – 6 weeks depending on the state of your lawn.
mWARNING! Before carrying out any repairs or
servicing work, you must ensure that the machine has been
