IMPORTANT SAFETY INSTRUCTIONS FOR  
CIRCULAR SAWS  
KEEP GUARDS IN PLACE AND IN WORKING  
ORDER. Never wedge or tie lower blade guard open.  
Check operation of lower blade guard before each use.  
Do not use if lower blade guard does not close briskly  
over saw blade.  
Stay alert – exercise caution.  
Don't remove saw from work during a cut while the  
blade is moving. See Pages 13 and 14.  
If saw is dropped, lower blade guard or bumper may be  
bent, restricting full return. If lower blade guard or  
bumperbecomesbentordamaged,replacethembefore  
reuse.  
BEFORE MAKING A CUT, BE SURE THE DEPTH  
AND BEVEL ADJUSTMENTS ARE TIGHT.  
USE ONLY CORRECT BLADES. Do not use blades  
with incorrect size holes. Never use blade washers or  
boltsthataredefectiveorincorrect.Themaximumblade  
capacity of your saw is 5-1/2 inches (140 mm).  
KEEP BLADES CLEAN AND SHARP. Sharp blades  
minimize stalling and kickback.  
NEVER touch the blade or other moving parts during  
use.  
DANGER:  
KEEP HANDS AWAY FROM CUTTING AREA. Keep  
hands away from blade. Do not reach underneath work  
while blade is rotating. Do not attempt to remove cut  
material when blade is moving.  
NEVER start a saw when its blade is touching the  
workpiece.  
NEVER lay a tool down before its moving parts have  
come to a complete stop.  
SAVE THESE INSTRUCTIONS. Refer to them  
frequently and use them to instruct others who may use  
this tool. If you loan someone this tool, loan them these  
instructions also.  
Blades coast after turn off.  
USE RIP FENCE. Always use a fence or straight edge  
guide when ripping.  
SUPPORT LARGE PANELS. To minimize the risk of  
blade pinching and kickback, always support large  
panels as shown in Figure 11, Page 12. When cutting  
operation requires the resting of the saw on the  
workpiece, the saw should be rested on the larger  
portion and the smaller piece cut off.  
WARNING:  
Some dust created by power sanding, sawing, grinding,  
drilling, and other construction activities contains  
chemicals known to cause cancer, birth defects or  
other reproductive harm. Some examples of these  
chemicals are:  
LOWER BLADE GUARD.  
• lead from lead-based paints,  
Make sure cord is located so that it will not be stepped  
on, tripped over, or otherwise subjected to damage or  
stress.  
• crystalline silica from bricks and cement and other  
masonry products, and  
If lower blade guard must be raised to make a cut,  
always raise it with the retracting handle to avoid  
serious injury. See Figure 20, Page 16.  
• arsenicandchromiumfromchemically-treatedlumber.  
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 filter  
out microscopic particles.  
GUARD AGAINST KICKBACK.  
Kickback occurs when the saw stalls rapidly and is  
driven back towards the operator.  
Releaseswitchimmediatelyifbladebindsorsawstalls.  
Keep blades sharp.  
WARNING:  
The operation of any power tool can result in foreign objects being thrown into your  
eyes, which can result in severe eye damage. Before beginning power tool operation,  
always wear safety goggles or safety glasses with side shields and a full face shield  
when needed. We recommend Wide Vision Safety Mask for use over eyeglasses or  
standard safety glasses with side shields. Always use eye protection which is marked

LOWER BLADE GUARD  
IS IN UP POSITION  
WHEN MAKING A CUT  
SAW BLADES  
The best of saw blades will not cut efficiently if they are not  
kept clean, sharp, and properly set. Using a dull blade will  
place a heavy load on your saw and increase the danger of  
kickback. Keep extra blades on hand, so that sharp blades  
are always available.  
Gum and wood pitch hardened on blades will slow your saw  
down. Use gum and pitch remover, hot water, or kerosene to  
remove these accumulations. DO NOT USE GASOLINE.  
BLADE GUARD SYSTEM  
Thelowerbladeguardattachedtoyourcordlesscircular  
saw is there for your protection and safety. It should  
never be altered for any reason. If it becomes damaged  
or begins to return slow or sluggish, do not operate your  
saw until the damage has been repaired or replaced.  
Always leave guard in operating position when using saw.  
BLADE EXPOSED ON  
UNDERSIDE OF WORKPIECE  
Fig. 7  
Never use saw when guard is not operating correctly.  
Guard should be checked for correct operation before  
each use. If you drop your saw, check the lower blade  
guard and bumper for damage at all depth settings  
before reuse.  
DANGER:  
When sawing through workpiece, lower blade guard does  
not cover blade on the underside of workpiece. Since  
blade is exposed on underside of workpiece, keep hands  
and fingers away from cutting area. Any part of your body  
coming in contact with moving blade will result in serious  
injury. See Figure 7.  
NOTE: The guard is operating correctly when it moves

reasonyourlowerbladeguarddoesnotclosefreely,take  
it to the nearest Ryobi authorized service center for  
service before using.

OPERATION  
KICKBACK  
See Figure 8.  
The best guard against kickback is to avoid dangerous  
practices.  
Kickback occurs when the blade stalls rapidly and the saw is  
driven back towards you. Blade stalling is caused by any  
action which pinches the blade in the wood.

below the material to be cut. See Figure 10. One blade  
tooth below the material to be cut works best for most  
efficient cutting action.  
Inspect the workpiece for knots or nails before beginning  
a cut. Never saw into a knot or nail.  
Make straight cuts. Always use a straight edge guide  
when rip cutting. This helps prevent twisting the blade in  
the cut.  
Always use clean, sharp and properly set blades. Never

OPERATION  
When making a cut use steady, even pressure. Never  
force cuts.  
Do not cut warped or wet lumber.  
Always hold your saw firmly with both hands and keep  
your body in a balanced position so as to resist the forces  
of kickback should it occur.  
When using your saw, always stay alert and exercise  
control. Do not remove your saw from workpiece while  
the blade is moving.  
DEPTH OF CUT ADJUSTMENT  
Always keep correct blade depth setting. The correct blade  
depth setting for all cuts should not exceed 1/4 inch (6.4 mm)  
below the material to be cut. More blade depth will increase  
the chance of kickback and cause the cut to be rough. One  
blade tooth below the material to be cut works best for most  
efficient cutting action.

OPERATION  
TO HELP MAINTAIN CONTROL:  
Always support your workpiece near the cut.  
Support your workpiece so the cut will be on your left.  
Clamp your workpiece so it will not move during the cut.  
Place your workpiece with its good side down.  
NOTE: The good side is the side on which appearance is  
important.  
Before beginning a cut, draw a guideline along the desired  
line of cut. Then place front edge of base on that part of your  
workpiece that is solidly supported. See Figure 13.

WARNING:  
WRONG  
Fig. 15  
The blade coming in contact with the workpiece before it  
reaches full speed could cause your saw to "kickback"  
towards you resulting in serious injury.  
When making a cut use steady, even pressure. Forcing  
causes rough cuts, could shorten the life of your saw and  
could cause "kickback."

When sawing through work, the lower blade guard does  
not cover the blade, exposing it on the underside of work.  
Keep your hands and fingers away from cutting area. Any  
part of your body coming in contact with the moving blade  
will result in serious injury.  
After you complete your cut release the trigger and allow the  
blade to come to a complete stop. Do not remove your saw  
from workpiece while the blade is moving.

GUIDELINE  
When making a cross cut or rip cut, align your line of cut  
with the outer blade guide notch on the saw base as  
shown in figure 17.  
Since blade thicknesses vary, always make a trial cut in  
scrap material along a guideline to determine how much, if  
any, the guideline must be offset to produce an accurate cut.  
NOTE:Thedistancefromthelineofcuttotheguidelineisthe  
amount you should offset the guideline.  
WIDTH OF CUT SCALE  
See Figure 18.  
A width of cut scale has been provided on the base of your  
saw. When making straight cross cuts or rip cuts, the scale  
can be used to measure up to four inches to the right side of  
the blade. It can be used to measure up to one inch to the left  
side of the blade.
