Lock-Off Button; Adjusting Blade Depth - Ryobi P504 Manual Del Operador

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.
BLADE GUARD SYSTEM
See Figure 9, page 15.
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 10, page 15.
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.
OPERATION

LOCK-OFF BUTTON

See Figure 10, page 15.
The lock-off button reduces the possibility of accidental
starting. The lock-off button is located on the handle above
the switch trigger. The lock-off button must be depressed
before you pull the switch trigger. The lock resets each time
the trigger is released.
NOTE: You can depress the lock-off button from either the
left or right side.

ADJUSTING BLADE DEPTH

See Figure 11, page 15.
Always keep correct blade depth setting. The correct blade
depth setting for all cuts should not exceed 1/4 in. below the
material being cut. More blade depth will increase the chance
of kickback and cause the cut to be rough. For more depth
of cut accuracy, a scale is located on the upper blade guard.
 Loosen the depth adjustment knob.
 Determine the desired depth of cut.
 Locate the depth of cut scale on the back of the upper
blade guard.
 Hold the base flat against the workpiece and raise or
lower the saw until the indicator mark on bracket aligns
with the notch on the blade guard.
 Tighten the depth adjustment knob securely.
OPERATING THE SAW
See Figures 12 - 14, page 15.
It is important to understand the correct method for operat-
ing the saw. Refer to the figures in this section to learn the
correct and incorrect ways for handling the saw.
WARNING:
To make sawing easier and safer, always maintain proper
control of the saw. Loss of control could cause an acci-
dent resulting in possible serious injury.
DANGER:
When lifting the saw from the workpiece, the blade is
exposed on the underside of the saw until the lower blade
guard closes. Make sure the lower blade guard is closed
before setting the saw down.
To make the best possible cut, follow these helpful hints:
 Hold the saw firmly with both hands.
 Avoid placing your hand on the workpiece while making
a cut.
 Support the workpiece so that the cut (kerf) is always to
your side.
 Support the workpiece near the cut.
 Clamp the workpiece securely so that the workpiece will
not move during the cut.
