IMPORTANT
SAFETY
INSTRUCTIONS To Reduce the Risk of Fire, Electric Shock or Injury:
Read all instructions before using this blower.
When using this blower basic precautions should always be
followed, including the following:
WARNING
If unit is vibrating, shut off immediately. abnormal vibration
indicates a mechanical problem and continued use could lead
to damage of unit or personal injury.
Call service center or manufacturer.
CAUTION

GROUNDING
INSTRUCTIONS
Improper use of the grounding plug can result in a
risk of electric shock.
Electrical equipment must be grounded. If
it should mal-function or breakdown,
grounding provides a path of least resist-
ance for electrical current to reduce the
risk of electric shock. The blower is
equipped with a cord having an equipment-
grounding conductor and grounding plug.
The plug must be inserted into an appropri-
ate outlet that is properly installed and
grounded in accordance with all local
codes and ordinances.
If repair or replacement of the cord or plug
is necessary, DO NOT connect the ground-
ed wire to either flat blade terminal. The
wire with insulation having an outer sur-
face that is green with or without yellow
stripes is the grounding wire.
GROUNDING
METHOD
This electric equipment is for use on a
nominal 120 volt circuit, and has a ground-
ed plug that looks like the plug illustrated in
(Fig A). A temporary adaptor that looks like
the adaptor illustrated in (Fig B & C) may
be used to connect this plug to a 2-pole
receptacle as shown in (Fig B) if a proper-
ly grounded outlet is not available.
The temporary adaptor should be used
only until a properly grounded outlet (Fig
A) can be installed by a qualified electri-
cian. The green color rigid ear, lug or the
like extending from the adaptor must be
connected to a permanent ground such as
a properly grounded outlet box cover.
Whenever the adaptor is used, it must be
held in place by a metal screw (Fig C).
Improper connection of the equipment-grounding conductor can result in a risk
of electric shock. Check with a qualified electrician or service person if you ar in
doubt as to whether the outlet is properly grounded. DO NOT modify the plug
provided with the equipment. If it will not fit the outlet, have a proper outlet
installed by a qualified electrician.
Note: In Canada, the use of a temporary adaptor is not permitted by the
Canadian Electrical Code.

cas dé défaillance ou de panne
éventuelles, la mise à la terre fournit au
courant un chemin de moindre résis-
tance qui réduit le risque de choc élec-
trique. Cet appareil est pourvu d'un cor-

muni d'une fiche de mise à la terre semblable à celle
illustrée par le croquis A de la figure "A". S'assurer que
l'appareil est branché à une prise de courant ayant la
même configuration que la fiche. Aucun adaptatteur ne
devrait être utilisé avec cet appareil.
AVERTISSEMENT
Un conducteur de terre mal raccordé peut entraîner un risque de choc électrique.
Consulter un électricien ou un technicien d'entretien qualifié si vous n'êtes pas certain
que la prise soit correctement mise à la terre. Ne pas modifier la fiche fournie avec
l'appareil-si elle ne peut être inséreé dans la prise, faire installer une prise adéquate
par un électricien qualifié.
