ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of serious
personal injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories,
when replacing line, or prior to cleaning. An
accidental start‑up can causeinjury.
Motor
Be sure your power supply agrees with the nameplate
marking. Voltage decrease of more than 10% will cause loss
of power and overheating. These tools are factory tested; if
this tool does not operate, check powersupply.
Servicing of Double Insulated Appliances
Your appliance is double‑insulated to give you added
safety. In a double insulated appliance, two systems of
insulation are provided instead of grounding. No grounding
means is provided on a double insulated appliance, nor
should a means for grounding be added to the appliance.
Servicing a double insulated appliance requires extreme
care and knowledge of the system and should be done
only by qualified service personnel. 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 insulated or “double insulation”. The
symbol (square within a square) may also be marked on
theappliance.
Safety Rules and Instructions:
ExtensionCords
Double insulated appliances have 2‑wire cords and can
be used with 2‑wire or 3‑wire extension cords. Only
round jacketed extension cords should be used, and we
recommend that they be listed by Underwriters Laboratories
(U.L.) (C.S.A. in Canada). If the extension will be used outside,
the cord must be suitable for outdoor use. Any cord marked
as outdoor can also be used for indoorwork.
Before using an extension cord, inspect it for loose or
exposed wires, damaged insulation, and defective fittings.
Make any needed repairs or replace the cord ifnecessary.
Safety Rules and Instructions:
PolarizedPlug
To reduce the risk of electric shock, this appliance has a
polarized plug (one blade is wider than the other). This
equipment must be used with a suitable polarized 2wire or
3wire extension cord. Polarized connections will fit together
only one way. Make sure that the receptacle end of the
extension cord has large and small blade slot widths. If the
plug does not fit fully into the extension cord, reverse the
plug. If it still does not fit, obtain a suitable extension cord. If
the extension cord does not fit fully into the outlet, contact a
qualified electrician to install the proper outlet. Do not change
the appliance plug or extension cord in anyway.

Safety Rules and Instructions:
Extension Cords

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.
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
cord will cause a drop in line voltage resulting in loss of
power and overheating. The table shows the correct size
to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The smaller
the gauge number, the heavier the cord. If the extension will
be used outside, the cord must be suitable for outdoor work.
The letters “WA” on the cord jacket indicate that the cord is
suitable for outdooruse.
