GROUNDING

proper precautions 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, centre 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.

d.

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.

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 making a

 

“plunge cut” into existing walls or

 

other blind areas. The protruding

 

blade may cut objects that can cause

 

kickback.

in all angles and depths of cut.

11.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 damaged parts, gummy deposits, or a build-up of debris.

12.Lower guard should be retracted manually only for special cuts such as “plunge cuts”and “compound cuts.” Raise lower guard by retract- ing handle and as soon as blade enters the material, the lower guard must be released. For all other saw- ing, the lower guard should operate automatically.

13.Always observe that the lower guard is covering the blade before plac- ing saw down on bench or floor. 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.

14.Do not use abrasive wheels with circular saws. Dust and grit can cause lower guard to hang up and not operate properly.

15.Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.

16.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 ce- ment and other masonry products, and

•arsenic and chromium from chemi- cally-treated lumber.

WARNING

Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electri- cian if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the cord or plug is damaged. If damaged, have it repaired by a MILWAUKEE service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.

Some models are provided with a 20 amp locking plug (NEMA L5-20).

Grounded Tools:

Tools with Three Prong Plugs

Tools marked “Grounding Required” have a three wire cord and three prong grounding plug. The plug must be connected to a prop- erly grounded outlet (See Figures A and B). If the tool should electrically malfunction or break down, grounding provides a low resis- tance path to carry electricity away from the user, reducing the risk of electric shock.

The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire con- nected to the tool’s grounding system and must never be attached to an electrically “live” terminal.

Your tool must be plugged into an appropri- ate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in Figures A and B.

Double Insulated Tools:

Tools with Two Prong Plugs

Tools marked “Double Insulated” do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association and the National Electrical Code. Double Insulated tools may be used in either of the 120 volt outlets shown in Figures C and D.

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 position. If saw is acciden-

tally dropped, lower guard may be bent.

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.
