SERVICE
AND
REPAIRS
All
quality tools
will
eventually require servicing or
replacement
of parts
due
to
wear from
normal
use.
These
operations should
ONLY
be performed by an
AUTHORIZED
HITACHI
POWER
TOOL
REPAIR SHOP.
REPLACEMENT PARTS
When
servicing
use only
identical
replacement
parts.
POLARIZED
PLUGS
To
reduce
the
risk
of
electric
shock,
this
equipment
has
a
polarized
plug
(one blade
is
wider than the
other).
This plug
will
fit
in
a
polarized outlet
only
one way.
If
the plug
does
not
fit
fully
in
the
outlet,
reverse the plug.
If
it
still
does
not
fit,
contact
a qualified
electrician
to
install
the proper
outlet.
Do
not
change
the plug
in
any way.

your
extension cord
is
in
good
condision.
When
using an
extension cord,
be
sure to
use
one
heavy
enough

the current
your
product
will
draw.
An
undersized cord
will
cause
a
drop
in line
voltage
resulting
in
loss
of
power and
overheating. Table
shows
the correct
size
to
use depending
on
cord
length
and nameplate ampere
rating.
If
in
doubt,
use the
next heavier
gage.
The
smaller
the
gage number,
the
heavier the
cord.
