RULES FOR SAFE OPERATION (Continued)

25. INSPECT TOOL CORDS PERIODICALLY

and if damaged, have repaired at your nearest
authorized service center. Stay constantly
aware of cord location and keep it well away
from the rotating blade.

26. INSPECT EXTENSION CORDS PERIODI-

CALLY and replace if damaged.

27. KEEP HANDLES DRY, CLEAN, AND FREE

FROM OIL AND GREASE. Always use a
clean cloth when cleaning. Never use brake
fluids, gasoline, petroleum-based products,
or any strong solvents to clean your tool.

28. STAY ALERT AND EXERCISE CONTROL.

Watch what you are doing and use common
sense. Do not operate tool when you are tired.
Do not rush.

29. CHECK DAMAGED PARTS. Before further

use of the tool, a guard or other part that is
damaged should be carefully checked to
determine that it will operate properly and
perform its intended function. Check for
alignment of moving parts, binding of moving
parts, breakage of parts, mounting, and any
other conditions that may affect its operation.
A guard or other part that is damaged should
be properly repaired or replaced by an
authorized service center.

30. DO NOT USE TOOL IF SWITCH DOES NOT

TURN IT ON AND OFF. Have switches
replaced by an authorized service center.

31. DRUGS, ALCOHOL, MEDICATION. Do not

operate this tool while under the influence of
drugs, alcohol, or any medication.

32. GUARD AGAINST KICKBACK.  Kickback

occurs when the blade stalls rapidly and the
biscuit joiner is driven in the direction opposite
blade rotation. Release switch immediately if
blade binds or joiner stalls.

33. USE ONLY 1-1/2 in. (38 mm) DIAMETER

SPECIFIED BLADES. Do not use blades with
incorrect size holes. Never use blade washers
or bolts that are defective, incorrect, or not
specified.

34. AVOID CUTTING NAILS. Inspect for and

remove all nails from lumber before cutting.

35. NEVER touch the blade or other moving parts

during use.

36. NEVER  start a tool when the blade is in

contact with the workpiece.

37. NEVER lay a tool down before the blade has

come to a complete stop.

38. POLARIZED PLUGS. To reduce the risk of

electric shock, this equipment has a polarized
plug (one blade is wider than the other). This
plug will fit in a polarized outlet only one way.
If the plug does not fit fully in the outlet,
reverse the plug. If it still does not fit, contact
a qualified electrician to install the proper
outlet. Do not change the plug in any way.

39. WHEN SERVICING USE ONLY IDENTICAL

RYOBI REPLACEMENT PARTS.

40. 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.

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:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other

masonry products, and

• arsenic and chromium from chemically-treated

lumber.

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.
