Maintenance; Brush Replacement; Troubleshooting - Delta ShopMaster S26-272L Instruction Manual

To reduce the risk of injury, turn unit off
and disconnect it from power source
before cleaning or servicing, before installing and
removing accessories, before adjusting when making
repairs. An accidental start-up can cause injury.
KEEP MACHINE CLEAN
Periodically blow out all air passages with dry
compressed air. All plastic parts should be cleaned
with a soft damp cloth. NEVER use solvents to clean
plastic parts. They could possibly dissolve or otherwise
damage the material. Wear certified safety equipment
for eye, hearing and respiratory protection while using
compressed air.
Empty dust bag frequently.
When servicing, use only identical
replacement parts. Use of any other
parts may create a hazard or cause product damage.
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.

BRUSH REPLACEMENT

The motor on this saw features externally accessible
brush assemblies that should be periodically checked for
wear. If the brushes need to be replaced, refer to Figure
30 and proceed as follows:
1. Unplug the saw.
Failure to unplug the saw could result in
accidental starting causing serious
personal injury.
2. Using a screwdriver, carefully remove the brush cap
(A).
NOTE: Remove the cap slowly. The brush assembly is
spring-loaded and will pop out once the cap is removed.
3. Remove brush assembly (B).
4. Inspect both brushes. If either has less than 1/4 in.
length of carbon remaining, both brushes should be
replaced.
NOTE: Do not replace one side without replacing the
other.
5. Insert both brushes into the brush tube (C), making
sure the curvature of the brushes matches curvature
of motor. Brush assembly should move freely within
the tube.
6. Carefully replace the brush cap, ensuring that it is not
cross-threaded.
7. Tighten brush cap securely. Do not over-tighten.
FAILURE TO START
If your machine fails to start, check to make sure the prongs on the cord plug are making good contact in the receptacle.
Also, check for blown fuses or open circuit breakers in your power supply line. If the saw still does not start, call
Company's Customer Care Center at 1-800-223-7278.

MAINTENANCE

Use clean cloths to remove dirt, dust, oil, grease, etc.
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, commutator,
etc. Consequently, we do not recommend 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 lubrication is required.
