7.5 BLADE GUARD SYSTEM
The lower blade guard attached to your cordless circular saw is there for your protection and safety. It should never be altered
for any reason. If it becomes damaged or begins to return slowly or sluggishly, do not operate your saw until the guard has
been repaired or replaced. Always leave the guard in operating position when using the saw.
DANGER:
When sawing through a workpiece, the lower blade guard does not cover the blade on the underside of the work-
piece. Since the blade is exposed on the underside of the workpiece, keep hands and fingers away from the cutting
area. Because of the risk of serious bodily injury, the rotating blade must never come into contact with any part of
your body. See Figure 5.
Never use your saw when the guard is not operating correctly. The guards should be checked for correct operation
before each use. If you drop your saw, check the lower blade guard and riving knife for damage at all depth settings
before using it again.
NOTE: The guard is operating correctly when it moves freely and readily returns to the closed position. If for any
reason your lower blade guard does not close freely, take it to the nearest Ryobi Authorised Service Centre to have
it repaired.

7.6 KICKBACK
See Figure 6.
The best guard against kickback is to avoid dangerous practices.
Kickback occurs when the saw jams up suddenly and the saw is driven back towards the operator. Blade jamming occurs
when the blade is pinched in the wood.
DANGER:
Release the switch immediately if the blade binds or if the saw jams up. Kickback could cause you to lose control of
your saw. Loss of control can lead to serious injury.
KICKBACK IS CAUSED BY:
• Incorrect blade depth setting. See Figure 6.
• Sawing into knots or nails in workpiece.
• Twisting blade while making a cut.
• Making a cut with a dull, gummed up, or improperly set blade.
• Incorrectly supported workpiece. See Figure 7.
• Forcing a cut
• Cutting warped or wet lumber.
• Tool misuse or non compliance with operating procedures.
TO MINIMISE THE RISK OF KICKBACK:
• Always keep the correct blade depth setting – this should not exceed 6 mm (1/4'') below the material to be cut. See Figure
8. For efficient cutting, a single blade tooth should protrude below the material to be cut.
• 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 making rip cuts. This helps prevent twisting of the blade.
• Always use clean, sharp and properly set blades. Never cut with dull blades.
• To avoid pinching the blade, support the workpiece properly before beginning a cut. The right and wrong ways to support
large pieces of work are shown in Figures 7 and 9.
• 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 in control of your tool. Do not remove your saw from the workpiece
while the blade is moving.
