Safety Instructions For All Saws; Cutting Procedures - Porter-Cable PCE381 Instruction Manual

f ) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
g ) Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking
into account the working conditions and the
work to be performed. Use of the power tool for
operations different from those intended could result
in a hazardous situation.
h ) Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
5) Service
a ) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.

SAFETY INSTRUCTIONS FOR ALL SAWS

Cutting Procedures

a ) DAngER: Keep hands away from cutting area
and the blade.
b ) Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
c ) Adjust the cutting depth to the thickness of the
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
d ) Never hold piece being cut in your hands or
across your leg. Secure the workpiece to a stable
platform. It is important to support the work properly
to minimize body exposure, blade binding, or loss of
control.
e ) Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting tool may contact hidden wiring or its
own cord. Contact with a "live" wire will also make
exposed metal parts of he power tool "live" and could
give the operator an electric shock.
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 arbor holes. Blades
that do not match the mounting hardware of the saw
will run off centre, 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.
Kickback Causes And Related Warnings:
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 firm grip on the saw and position
your arms to resist kickback forces. Position
your body to 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.
c ) When restarting a saw in the workpiece, center
the saw blade in the kerf and check that saw
teeth are not engaged into the material. If saw
blade 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
blade 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 blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f ) Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
g ) Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
Lower Guard Function
a ) Check guard for proper closing before each
use. Do not operate the saw if guard does not
move freely and enclose the blade instantly.
Never clamp or tie the lower guard into the open
position. If saw is accidentally dropped, guard
may be bent. Check to make sure that the guard
moves freely and does not touch the blade or any
other part, in all angles and depths of cut.
b ) Check the operation of the guard spring. If the
guard and the spring are not operating properly,
they must be serviced before use. Guard may
