MAINTENANCE
WARNING:
When servicing, use only identical Ryobi replacement
parts. Use of any other parts may create a hazard or
cause product damage.
WARNING:
Always wear safety goggles or safety glasses with side
shields during power tool operation or when blowing
dust. If operation is dusty, also wear a dust mask.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. After extended use, lubricate
table rollers and clean the slide rod so the table will slide
smoothly.
CLEANING THE SLIDE ROD
During use, the slide rod will become dirty preventing the
table rollers from sliding smoothly. It is important to clean
the slide rod often using a clean, dry cloth.
BRUSH REPLACEMENT

The saw has externally accessible brush assemblies that
should be periodically checked for wear.
Proceed as follows when replacement is required:

Failure to unplug the saw could result in accidental start-
ing causing serious injury.
 Remove brush cap with a screwdriver. Brush assembly is
spring loaded and will pop out when you remove brush
cap.

 Check for wear. Replace both brushes when either has
less than 1/4 in. length of carbon remaining. Do not
replace one side without replacing the other.
 Reassemble using new brush assemblies. Make sure

brush moves freely in brush tube.
 Make sure brush cap is oriented correctly (straight) and
replace.
 Tighten brush cap securely. Do not overtighten.
