Further Safety Instructions For All Saws - Hitachi C 18DSL Handling Instructions Manual

English
Contact with a "live" wire will also make exposed metal parts of the power
tool "live" and shock the operator.
f) When ripping always use a rip fence or straight edge guide.
This improves the accuracy of cut and reduces the chance of blade
binding.
g) Always use blades with correct size and shape (diamond versus
round) of arbour holes.
Blades that do not match the mounting hardware of the saw will run
eccentrically, causing loss of control.
h) Never use damaged or incorrect blade washers or bolt.
The blade washers and bolt were specially designed for your saw, for
optimum performance and safety of operation.
Never use any abrasive wheels
○
Burst of abrasive wheel cause serious injury of operator or persons
around the working area.

FURTHER SAFETY INSTRUCTIONS FOR ALL SAWS

Causes and operator prevention of kickback:
– kickback is a sudden reaction to a pinched, bound or misaligned saw
blade, causing an uncontrolled saw to lift up and out of the workpiece
toward the operator;
– when the blade is pinched or bound tightly by the kerf closing down, the
blade stalls and the motor reaction drives the unit rapidly back toward the
operator;
– if the blade becomes twisted or misaligned in the cut, the teeth at the back
edge of the blade can dig into the top surface of the wood causing the
blade to climb out of the kerf and jump 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 fi rm grip with both hands on the saw and position your
arms to resist kickback forces.
Position your body either side of the blade, but not in line with the
blade.
Kickback could cause the saw to jump backwards, but kickback forces
can be controlled by the operator, if proper precautions are taken.
b) When blade is binding, or when interrupting a cut for any reason,
release the trigger and hold the saw motionless in the material
until the blade comes to a complete stop.
Never attempt to remove the saw from the work or pull the saw
backward while the blade is in motion or kickback may occur.
Investigate and take corrective actions to eliminate the cause of blade
binding.
