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 at-

tempt 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.

• When restarting a saw in the workpiece, centre

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.

• Support large panels to minimise 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.

• Do not use dull or damaged blades. Unsharp-

ened or improperly set blades produce narrow

kerf causing excessive friction, blade binding and

kickback.

• 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.

• 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

• 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

position. 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.

• Check the operation of the lower guard spring.

If the guard and the spring are not operating

properly, they must be serviced before use.

Lower guard may operate sluggishly due to dam-

aged parts, gummy deposits, or a build-up of

debris.

• 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.

• Always observe that the lower guard is cov-

ering the blade before placing saw down on

bench or oor. An unprotected, 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.

• Maintain labels and nameplates. These carry

important information. If unreadable or missing,

contact a MILWAUKEE service facility for a free

replacement.

• WARNING Some dust created by power sanding,

sawing, grinding, drilling, and other construction

activities contains chemicals known to cause

SPECIFIC SAFETY RULES

Cutting procedures

•

DANGER: Keep hands away from cutting

area and the 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.

• Do not reach underneath the workpiece. The

guard cannot protect you from the blade below the

workpiece.

• 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.

• 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.

• Hold the power tool by insulated gripping

surfaces only, 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 the power

tool “live” and could give the operator an electric

shock.

• When ripping, always use a rip fence or straight

edge guide. This improves the accuracy of cut

and reduces the chance of blade binding.

• 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.

• 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 un-

controlled 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 incor-

rect operating procedures or conditions and can

be avoided by taking proper precautions as given

below:

• Maintain a rm 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 kick-

back forces can be controlled by the operator, if

proper precautions are taken.

• When blade is binding, or when interrupting
