DANGER:

1.	Keep hands away from cutting area
	and blade. Keep your second hand
	on auxiliary handle or motor housing.
	If both hands are holding the saw, they
	cannot be cut by the blade.
2.	Do not reach underneath the work-
	piece. The guard cannot protect you
	from the blade below the workpiece.
3.	Adjust the cutting depth to the thick-
	ness of the workpiece. Less than a full
	tooth of the blade teeth should be visible
	below the workpiece.
4.	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.
5.	Hold tools by insulated gripping sur-
	faces 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.
6.	When ripping always use a rip fence
	or straight edge guide. This improves
	the accuracy of cut and reduces the
	chance for blade binding.
7.	Always use blades with correct size
	and shape (diamond versus round)
	arbor holes. Blades that do not match
	the mounting hardware of the saw will
	run eccentrically, causing loss of con-

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 operator.

Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precau- tions as given below:

a. Maintain a firm grip with both hands

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 inter-

rupting a cut for any reason, release

the trigger and hold the saw motion-

less 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 cor-

rective actions to eliminate the cause

of blade binding.

c. When restarting a saw in the work-

piece, center the saw blade in the kerf

and check that saw teeth are not en-

gaged into the material. If saw blade is

binding, it may walk up or kickback from

the workpiece as the saw is restarted.

blade may cut objects that can cause

kickback.

10.Check lower guard for proper closing before each use. Do not operate the saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open po- sition. If saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.

11.Check the operation and condition of the lower guard spring. If the guard and the spring are not operat- ing properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gum- my deposits, or a buildup of debris.

12.Lower guard should be retracted manually only for special cuts such as "Plunge Cuts" and "Compound Cuts". Raise lower guard by retracting handle and as soon as blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically.

protected, coasting blade will cause the

saw to walk backwards, cutting whatever

is in its path. Be aware of the time it

takes for the blade to stop after switch is

released.

14. Maintain labels and nameplates. These

carry important information. If unread-

able or missing, contact a MILWAUKEE

service facility for a free replacement.

15. WARNING: Some dust created by

power sanding, sawing, grinding, drill-

ing, and other construction activities

contains chemicals known to cause

cancer, birth defects or other reproduc-

tive harm. Some examples of these

chemicals are:

•lead from lead-based paint

•crystalline silica from bricks and cement and other masonry

products, and

•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 ven- tilated area, and work with approved safety equipment, such as those dust masks that are specifically designed to filter out microscopic particles.

8. Never use damaged or incorrect blade

washers or bolts. The blade washers

and bolts were specially designed for

your saw, for optimum performance and

safety of operation.

9. 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.

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 blade.
	Unsharpened or improperly set blades
	produce narrow kerf causing excessive
	friction, blade binding and kickback.
f.	Blade depth and bevel adjusting lock-
	ing levers must be tight and secure
	before making cut. If blade adjustment
	shifts while cutting, it may cause binding
	and kickback.
