SAFETY NOTICE: Exposure to vibra-
tions through prolonged use of hand
tools could caus e blood vessel or nerve
damage in the fingers, hands, a nd joints
of people prone to circulation disorders
or abnormal swelling. Prolonged use in
cold weather has been linked to blood
vessel damage in otherwise healthy
people. If symptoms occur such as
numbness, pain, loss of strength,
change in skin color or texture, or loss of
feeling in the fingers, hands, or joints,
discontinue the use of this tool and seek
medical a ttention. An anti-vibration sys-
tem does not guarantee the avoidance
of these problems. Users who operate
power tools on a continual and regular
basis must closely monitor theirphysical
condition and the condition of this tool.
DOUBLE INSULATION
CONSTRUCTIO N
This unit is double insulated to help pro-
tect against electric shock. Double in-
sulation construction c onsists of two
separate “layers” of electrical insulation
instead of grounding.
Tools builtwith thisinsulation systemare
not intended to be grounded. No
grounding means is provided on this
unit, nor should a means of grounding
be added to this unit.
Safety precautions must be observed
when operating any electrical tool. The
double insulation system only provides
added protection against injury resulting
from an internal electrical insulation
failure.
WARNING: All e lect r ical repair s to
this unit, including housing, swi t ch, motor,
etc., must be diagnosed and repai r ed by
qualif i ed service personnel. Replacement
parts for a double insulated appliance
must be iden t ical to the par ts they r eplace.
A double insul ated appliance is marked
wit h the wor ds “double insulation” or
“double insulat ed”. The symbol
(square wi t hin a square) may also be
marked on the appl i ance. Failure to have
the unit repaired by authorized ser vi ce
personnel can cause the double i nsula-
tion construction to become ineffective
and result in serious injury .
