ADJUSTMENTS

DEPTH STOP ADJUSTMENTS

See Figure 43.

nUnplug the saw.

nTo adjust the depth stop use a 10 mm wrench or adjustable wrench and loosen the hex nut at the rear of the miter saw arm.

nUse a 5 mm hex key wrench to adjust the depth stop adjustment screw. The saw blade is lowered by turning the screw counterclockwise and raised by turning the screw clockwise.

nLower the blade into the miter table. Check blade clearance and maximum cutting distance (distance from fence where blade enters) to front of miter table slot.

nReadjust if necessary.

nTighten the hex nut with a 10 mm wrench or adjustable wrench.

nTo prevent the depth stop adjustment screw from turning while tightening the hex nut, carefully hold it with the hex key wrench while tightening the hex nut.

MAINTENANCE

WARNING: When servicing, use only identical replacement parts. Use of any other part 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

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, carbon dust, etc.

celerated wear and possible premature failure when they are used on fiberglass boats, sports cars, wallboard, spackling compounds, or plaster. The chips and grindings from these materials are highly abrasive to electric tool parts such as bearings, brushes, commutators, etc. Con- sequently, it is not recommended that this tool be used for extended work on any fiberglass material, wallboard, spackling compounds, or plaster. During any use on these materials it is extremely important that the tool is cleaned frequently by blowing with an air jet.

LUBRICATION

All of the bearings in this tool are lubricated with a suffi- cient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required.

WARNING: To ensure safety and reliability, all repairs — with the exception of the externally acces- sible brushes — should be performed by a qualified service technician at a Sears store to avoid risk of personal injury.

Your 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 starting 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.
