SERVICE
Z_WARNING: Preventivemaintenance performedby unauthorizedpersonnelmay
resultin misplacing of internalwires and components, whichcould cause a serious hazard.
1. When servicing a tool, use only identical replacement parts. Follow instructionsin the
maintenance section of this manual. Use of unauthorized parts or failure to follow
maintenance instructions may create a risk of electrical shock or serious personal injury.
2. All service that requires opening the sabre saw MUST only be performed by a Sears
Service Center. All motor parts represent an important part of the double insulation
system and MUST only be serviced by a Sears Service Center. Service performed by
unqualified personnel could result in a risk of injury.
3. 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.
GENERAL
z_WARNING! To avoid accidents, ALWAYS disconnect the tool from the power I
source BEFORE cleaning or performing any maintenance.
I
./_WARNING! DO NOT at any time let brake fluids, gasoline, petroleum-based I
products, penetrating oils, etc. to come in contact with plastic parts. They contain
I
chem ca s that can damage, weaken or destroy plastic.
4, It is a known fact that electric tools are subject to accelerated wear and possible
premature failure when they are used to work on fiber glass boats and sports cars,
wallboard, spackling compounds or plaster. The chips and grindings from these materials
are highly abrasive to electdcal tool parts, such as bearing, brushes, commutators, etc.
Consequently, it is not recommended that this tool be used for extended work on any
fiber glass material, wallboard, spackling compound, 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 beadngs in this tool are lubricated with a sufficient amount of high-grads
lubricant for the life of the tool under normal operating conditions. Therefore, no further
lubrication is required.
Z_WARNINGI ALWAYS wear safety goggles or safety glasses with side shields
when using this tool or blowing dust. If operation is dusty,also wear a dust mask.
DOUBLE INSULATION
Double insulation is a concept in safety in electdc power tools which eliminates the need
for the standard 3-wira grounded power cord, All exposed metal parts are isolated from
the internal motor components with protecting insulation. Double insulated tools do not
need to be grounded.
