Saw Blades - Ryobi P508 Manuel D'utilisation

To guard against kickback, avoid dangerous practices
such as the following:
 Setting blade depth incorrectly.
 Sawing into knots or nails in workpiece.
 Twisting the blade while making a cut.
 Making a cut with a dull, gummed up, or improperly set
blade.
 Supporting the workpiece incorrectly.
 Forcing a cut.
 Cutting warped or wet lumber.
 Operating the tool incorrectly or misusing the tool.
To lessen the chance of kickback, follow these safety
practices:
 Keep the blade at the correct depth setting. The depth
setting should not exceed 1/4 in. below the material being
cut.
 Inspect the workpiece for knots or nails before cutting.
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.
 Use clean, sharp, and properly set blades. Never make
cuts with dull blades.
 Support the workpiece properly before beginning a cut.
 Use steady, even pressure when making a cut. Never
force a cut.
 Do not cut warped or wet lumber.
 Hold the saw firmly with both hands and keep your body
in a balanced position so as to resist the forces if kickback
should occur.
WARNING:
When using the saw, always stay alert and exercise con-
trol. Do not remove the saw from the workpiece while the
blade is moving.

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 the 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 the
saw down. Remove saw blade from the saw and use gum
and pitch remover, hot water, or kerosene to remove these
accumulations. DO NOT USE GASOLINE.
OPERATION
BLADE GUARD SYSTEM
See Figure 8, page 14.
The lower blade guard attached to the circular saw is there
for your protection and safety. Do not alter it for any reason.
If it becomes damaged, do not operate the saw until you
have the guard repaired or replaced. Always leave guard in
operating position when using the saw.
DANGER:
When sawing through work, lower blade guard does not
cover blade on the underside of work. Since blade is
exposed on underside of work, keep hands and fingers
away from cutting area. Any part of your body coming
in contact with moving blade will result in serious injury.
CAUTION:
Never use saw when guard is not operating correctly.
Check the guard for correct operation before each use.
The guard is operating correctly when it moves freely and
readily returns to the closed position. If you drop the saw,
check the lower blade guard and bumper for damage at
all depth settings before reuse.
STARTING/STOPPING THE SAW
See Figure 9, page 14.
This saw is equipped with a worklight that will turn on when
the trigger is depressed and will turn off when the trigger
is released.
To start the saw:
 Depress the lock-off button.
 Depress the switch trigger.
Always let the blade reach full speed, then guide the saw
into the workpiece.
WARNING:
The blade coming in contact with the workpiece before
it reaches full speed could cause the saw to "kickback"
towards you resulting in serious injury.
To stop the saw: release the switch trigger.
After you release the switch trigger, allow the blade to come
to a complete stop. Do not remove the saw from the
workpiece while the blade is moving.
