TABLE A

USE PROPER EXTENSION CORD. 9.
Make sure your extension cord is
in good condition. When using an
extension cord, be sure to use one
heavy enough to carry the current
your product will draw. An undersized
cord will cause a drop in line voltage
resulting in loss of power and over­heating. Table A shows the correct
size to use depending on cord length
and nameplate ampere rating. If in
doubt, use the next heavier gauge.
The smaller the gauge number, the
heavier the cord.

WEAR PROPER APPAREL. Do not 10.
wear loose clothing, gloves, neck­ties, rings, bracelets, or other jewelry
which may get caught in moving
parts. Nonslip footwear is recom­mended. Wear protective hair cover­ing to contain long hair.

ALWAYS USE SAFETY GLASSES. 11.
Also use face or dust mask if cutting
operation is dusty. Everyday eye­glasses only have impact resistant
lenses, they are NOT safety glasses.

NEVER STAND ON TOOL. Serious 18.
injury could occur if the tool is tipped
or if the cutting tool is unintentionally
contacted.

CHECK DAMAGED PARTS. Before 19.
further use of the tool, a guard or
other part that is damaged should
be carefully checked to determine
that it will operate properly and per­form its intended function – check for
alignment of moving parts, binding
of moving parts, breakage of parts,
mounting, and any other conditions
that may affect its operation. A guard
or other part that is damaged should
be properly repaired or replaced.

DIRECTION OF FEED. Feed work 20.
into a blade or cutter against the
direction of rotation of the blade or

Don’t leave tool until it comes to a

Check with a qualied electrician or 4.
service personnel if the grounding
instructions are not completely under­stood, or if in doubt as to whether the
tool is properly grounded.

GROUNDING INSTRUCTIONS

TO PREVENT

ELECTRIC SHOCK
AND DEATH FROM
INCORRECT GROUNDING
WIRE CONNECTION
READ AND FOLLOW THESE
INSTRUCTIONS:

110-120 V~ Grounded Tools: Tools

with Three Prong Plugs

In the event of a malfunction or 1.
breakdown, grounding provides a
path of least resistance for electric
current to reduce the risk of electric
shock. This tool is equipped with an
electric cord having an equipment­grounding conductor and a ground­ing plug. The plug must be plugged
into a matching outlet that is properly
installed and grounded in accordance
with all local codes and ordinances.

Do not modify the plug provided – if it 2.

will not t the outlet, have the proper
outlet installed by a qualied electri-

cian.
Improper connection of the equip-3.

ment-grounding conductor can re­sult in a risk of electric shock. The
conductor with insulation having an
outer surface that is green with or
without yellow stripes is the equip­ment-grounding conductor. If repair
or replacement of the electric cord or
plug is necessary, do not connect the
equipment-grounding conductor to a
live terminal.

Use only 3-wire extension cords that 5.
have 3-prong grounding plugs and
3-pole receptacles that accept the
tool’s plug.

Repair or replace damaged or worn 6.
cord immediately.

To properly understand all safety 12.
warnings, be familiar with the follow­ing safety terms and equipment:

Through-sawing – A cut made from a.
one side of a board to the opposite
side, without stopping.

Kickback – A sudden reaction to a g.

pinched, bound, or misaligned blade,

causing an uncontrolled workpiece

to lift up and out of the saw toward

the operator.

Spreader – A metal plate that fol-h.

lows the saw blade to keep the kerf

(gap) from closing on the saw blade.

Spreaders, except riving knives,

must be aligned to the blade after

blade adjustment to prevent binding.

Construct a Push Stick out of Wood 13.
according to the guidelines on the fol­lowing page.

Ripcut or Ripping - A cut made paral-b.
lel to (along with) the grain of the
wood.

Crosscut or Crosscutting - A cut c.
made perpendicular (at a 90° angle)
to the grain of the wood.

Push-stick – A narrow strip of wood d.
or other soft material with a notch
cut into one end and which is used
to push short pieces of material
through saws. It provides a safe
distance between the hands and the
cutting tool. Must be narrower than

WARNING: Some dust created by 29.
power sanding, sawing, grinding, drill­ing, and other construction activities,
contains chemicals known [to the
State of California] to cause cancer,
birth defects or other reproductive
harm. Some examples of these
chemicals are:

• Lead from lead-based paints

• Crystalline silica from bricks and ce-

ment or other masonry products

• Arsenic and chromium from chemi­cally treated lumber
Your risk from these exposures var­ies, depending on how often you do
this type of work. To reduce your
exposure to these chemicals: work in
a well ventilated area, and work with
approved safety equipment, such as
those dust masks that are specially

designed to lter out microscopic

particles. (California Health & Safety
Code § 25249.5, et seq.)
