ADJUSTMENTS
POSITIVE STOP ADJUSTMENTS
See Figure 42.
NOTE: These adjustments were made at the factory and normally do not require readjustment.
To adjust:
nUnplug the saw.
nUsing two wrenches (one on the lock nut and one for the positive stop adjustment screw), loosen the lock nut securing the positive stop adjustment screw.
nLoosen the bevel lock knob by turning the knob counterclockwise.
nSquare the blade to the miter table as described in the Assembly section of this manual.
nRetighten bevel lock knob. Next, retighten lock nut securing the positive stop adjustment screw. Recheck
NOTE: The above procedure can be used to check blade squareness of the saw blade to the miter table at both 0° and 45° angles.
The saw has two scale indicators, one on the bevel scale and one on the miter scale. After squaring adjustments have been made, it may be necessary to loosen the indicator screws and reset them to zero.
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.
Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commu- tators, etc. Consequently, we do not recommended using this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the tool using compressed air.
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. Therefore, no further lubrica- tion is required.

BRUSH REPLACEMENT
See Figure 43.
The saw has externally accessible brush assemblies that should be periodically checked for wear.
Proceed as follows when replacement is required:
nUnplug the saw.
WARNING:
Failure to unplug the saw could result in accidental start- ing causing serious injury.
nRemove brush cap with a screwdriver. Brush assembly is spring loaded and will pop out when you remove brush cap.
nRemove brush assembly.
nCheck 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.
nReassemble using new brush assemblies. Make sure curvature of brush matches curvature of motor and that brush moves freely in brush tube.
nMake sure brush cap is oriented correctly (straight) and replace.
nTighten brush cap securely. Do not overtighten.
