Double Insulation For Safer Operation - Hitachi CM 4SB2 Instructions De Sécurité Et Mode D'emploi

b) When wheel is binding, or when interrupting a cut for any reason, release the
trigger 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 levers 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. Either the symbol " " or the words "Double
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.
