Additional Specific Safety Rules - Porter-Cable 557 Instruction Manual

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.
5) SERVICE
a) Have your power tool serviced by a qualified repair person using only identi-
cal replacement parts. This will ensure that the safety of the power tool is main-
tained.

ADDITIONAL SPECIFIC SAFETY RULES

• Keep hands away from cutting area. Keep hands away from blade. Do
not reach underneath work while blade is rotating.
•
If tool is dropped, guard may distort restricting operation. Keep
slide mechanism free of wood chips. Occasionally lubricate with light tool oil.
DO NOT OVER LUBRICATE as this creates excessive sawdust buildup.
•
Hold power tools 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 make exposed metal parts of the tool "live" and
shock the operator.
• Wait for the cutter to stop before setting the tool down. An exposed cutter
may engage the surface leading to possible loss of control and serious injury.
•
Use clamps or other practical way to secure and support the workpiece to a
stable platform. Holding the work by hand or against your body is unstable and
may lead to loss of control.
• Keep blades sharp. Sharp blades will do the job better and safer.
• When you have finished a cut be careful not to come into contact with the
blade. Turn off the motor immediately.
• Never hold work in or with your hand, lap, or against other parts of your body.
• Keep guards in working order. Check operation before each use. Do not use if
guard does not close briskly over blade.
• Avoid cutting nails and knots. Inspect for and remove all nails from lumber
before cutting. Try to layout cuts between knots.
•
Plate joiner blades must be rated for at least the speed recommended on
the tool. Blades running over the rated speed can fly apart and cause injury.
• Always use the guard. The guard protects the operator from broken plate joiner
blade fragments and unintentional contact with the blade.
• Laceration hazard. Never remove the return springs. If the springs are
removed the tool cannot be operated safely because the blade will not retract
following a cut.
EXTENSION CORD
An extension cord must have adequate wire size (AWG or American Wire Gauge)
for safety. The smaller the gauge number of the wire, the greater the capacity of the
cable, that is 16 gauge has more capacity than 18 gauge. An undersized cord will cause
a drop in line voltage resulting in loss of power and overheating. When using more than
one extension to make up the total length, be sure each individual extension contains at
least the minimum wire size. The following table shows the correct size to use depend-
ing on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge.
The smaller the gauge number, the heavier the cord.
