Double Insulation For Safer Operation - Hitachi CM 5SB Manual De Instrucciones

English
It is important to support the work properly to
minimize body exposure, wheel binding, or loss
of control.
d) Never use damaged or incorrect wheel washers
or wheel nut.
The wheel washers and wheel nut were specially
designed for your saw, for optimum performance
and safety of operation.
Causes and operator prevention of kickback:
– kickback is a sudden reaction to a pinched,
bound or misaligned wheel, causing an
uncontrolled saw to lift up and out of the
workpiece toward the operator.
– when the wheel is pinched or bound tightly
by the kerf closing down, the wheel stalls and
the motor reaction drives the unit rapidly back
toward the operator.
Kickback is the result of saw misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
a) Maintain a firm housing and position your arms
to resist kickback forces.
Position your body either side of the wheel, but
not in line with the wheel.
Kickback could cause the saw to jump backwards,
but kickback forces can be controlled by the
operator, if proper precautions are taken.
b) When wheel is binding, or when interrupting a cut
for any reason, turn off the switch and hold the
saw motionless in the material until the wheel
comes to a complete stop.
Never attempt to remove the saw from the work
or pull the saw backward while the wheel is in
motion or kickback may occur.
Investigate and take corrective actions to eliminate
the cause of wheel binding.
c) When restarting a saw in the workpiece, centre
the wheel in the kerf and check that wheel
segments are not engaged into the material.
If wheel is binding, it may walk up or kickback from
the workpiece as the saw is restarted.

d) Support large panels to minimize the risk of wheel
pinching and kickback.
Large panels tend to sag under their own weight.
Supports must be placed under the panel on both
sides, near the line of cut and near the edge of the
panel.
e) Do not use dull or damaged wheels.
Unsharpened or improperly set wheels produce
narrow kerf causing excessive friction, wheel
binding and kickback.
f) Wheel depth adjusting locking wing nut must be
tight and secure before making cut.
If wheel adjustment shifts while cutting, it may
cause binding and kickback.
DOUBLE INSULATION FOR SAFER
OPERATION
To ensure safer operation of this power tool, HITACHI
has adopted a double insulation design. "Double
insulation" means that two physically separated
insulation systems have been used to insulate the
electrically conductive materials connected to the power
supply from the outer frame handled by the operator.
Therefore, either the symbol "
insulation" appear on the power tool or on the
nameplate.
Although this system has no external grounding, you
must still follow the normal electrical safety precautions
given in this Instruction Manual, including not using the
power tool in wet environments.
To keep the double insulation system effective, follow
these precautions:
Only HITACHI AUTHORIZED SERVICE CENTER
should disassemble or assemble this power tool,
and only genuine HITACHI replacement parts
should be installed.
Clean the exterior of the power tool only with a
soft cloth moistened with soapy water, and dry
thoroughly.
Never use solvents, gasoline or thinners on plastic
components; otherwise the plastic may dissolve.
