wire cord without aground connection may be used
since the tool is double:insulated. Cord should be 16
gauge or heavier to prevent Overheating and loss of

16. Store idle Trimmer .indoors. When not in use. Trimmer
should be ,stored indoors in dry place out of reach of

18. Keep air vents clear of debris,
DOUBLE INSULATION
Double Insulation is a concept in safety, replacing the stan-
dard grounded supply system, in electric power tools. The
construction of adouble insulated too! affords comparable
protection to a properfy grounded tool without the necessity
for using a grounded conductor. The double insulation
system e_iminates the need for the usual three wire
grounded power cord and grounded supply system.
Wherever there is electric current in the tool there are two
complete sets of insulation to protect the user. All exposed
metal parts are isolated from the internal metal motor
components with protecting insulation. The lead wires,
switch, etc. with their functional insulation have the added
protection of non-conductive sleeving or housings to
complete the double insulation system.
6. To prevent disconnection of power supply cord from
the extension cord during bperation, see instructions
with Figure 3.
7. Avoid Dangerous Environment -- Do not use unit in
damp or wet areas.
8o Don't force this tool. it will work better and safer at the
:. •rate for which it was designed. If motor slows down
too much, pull away and allow unit to obtain full speed,
9. Do not use too! for any job except that for which it is
intended.
10, Do not immerse tool in water or operate in rain,
11. Don't overreach -- Keep proper footing and balance at
all times.
12. Don't abuse cord -- never carry appliance by cord or
yank cord from receptacle. Keep cord away from heat,
oil and sharp edges, Replace damaged cord
immediately.
13. Never carry plugged in appliance with finger on switch.
14. Disconnect toolfrom the power supply when not in use and
when making any repairs or inspections.
15. Maintain Trimmer with care and follow instructions for
replacing or rewinding spool.
SERVICING OF A TOOL WITH DOUBLE INSULATION
REQUIRES EXTREME CARE AND KNOWLEDGE OF THE
SYSTEM AND SHOULD BE PERFORMED ONLY BY A
QUALIFIED SERVICE TECHNICIAN. FOR SERVICE WE
SUGGEST YOU RETURN THE TOOL TO YOUR NEAREST
AUTHORIZED DEALER FOR REPAIR WHICH WILL BE
DONE WITH ORIGINAL FACTORY REPLACEMENT PARTS.
