Maintenance - Craftsman 315.175170 Operator's Manual

:
WARNING
When servicing, use only identical
Craftsman 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.
:
WARNING
Before performing any adjustment,
make sure the tool is unplugged from the power
supply and the switch is in the OFF ( O ) position.
Failure to heed this warning could result in serious
personal injury.
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, commutators, 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.
Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts should
be replaced at a Sears Service Center.

MAINTENANCE

CUTTERS
Get faster and more accurate cutting results by keeping
cutters clean and sharp. Remove all accumulated pitch and
gum from cutters after each use.
When sharpening cutters, sharpen only the inside of the
cutting edge. Never grind the outside diameter. Be sure
when sharpening the end of a cutter to grind the clearance
angle to the same angle as originally ground.
COLLET
Dust and chips may collect on the collet from time to time,
making it necessary to clean the collet. To do so, remove
the collet assembly and wipe it with a clean dry rag. Clean
the taper in the shaft in the same manner. Never immerse
the collet or end of the shaft in a solvent or in water. Before
replacing the collet assembly, put a drop of SAE30 motor
oil on the inside of the nut, on the threads of the shaft, and
on the taper in the shaft. Replace the collet assembly onto
the shaft by hand only. Never tighten the collet nut without
a cutter in the collet. This action could permanently damage
the collet.
BRUSH ASSEMBLIES
See Figure 24.
The router has externally accessible brush assemblies that
should periodically be checked for wear.
To replace brush assemblies:
 Unplug the router.
 Remove brush cap with a screwdriver. Brush assembly
is spring loaded and will pop out when you remove
brush cap.
 Remove brush assembly (brush and spring).
 Check for wear. If worn, always replace in pairs. Do not
replace one side without replacing the other.
 Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and that
brush moves freely in brush tube.
 Make sure brush cap is oriented correctly (straight) and
replace.
 Tighten brush cap securely. Do not over tighten.
