MAINTENANCE
8. Service And Care
CAUTION:
Always disconnect tool from power supply prior to maintenance.
a) Regularly clean the power tool’s air vents. The motor’s fan will draw dust and
residues inside the housing and excessive accumulated residue may reduce the
tool’s cooling capacity, shortening tool life. Periodically blow out all air passages
with dry compressed air. Wear safety glasses while using compressed air.
b) Clean plastic and rubber parts with a soft, damp cloth. NEVER use solvents to
clean plastic parts. Griot’s Garage Interior Cleaner is an effective solution.
c) Check for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents are caused by poorly maintained
power tools.
d) Have your power tool serviced by a qualified repair shop using only identical
replacement parts. This will ensure the safety of the power tool is maintained.
Failure To Start
a) Should your tool fail to start, check to make sure the prongs on the cord plug are
making good contact within the outlet. Also check for blown fuses or open circuit
breakers in the line.
b) If power tool persists in not starting, unplug and inspect motor brushes for
excessive wear. Replace if necessary.
c) Inspect power cord for cuts or shorts. Should excessive wear be identified,
contact Griot’s Garage for replacement cords and/or service.
Brush Replacement
Brushes are wear items and normal wear is not covered under warranty.
The power tool comes with a spare set of replacement brushes.
a) Remove Brush Side-Port plugs from both sides of tool using a small
flathead screwdriver, turning counter-clockwise.
b) Grasp brass brush pressure plates and retrieve brushes from tool.
Discard appropriately.
c) Install replacement brushes into brush port.
d) Insert the Brush Side-Port plug and rotate clockwise by hand.
e) Tighten Brush Side-Port plug using the flathead screwdriver. Do
not overtighten!
Lubrication
THE BOSS tool comes pre-lubricated at the backing plate-to-
shroud contact point. This area should be lubricated every
100 hours of operation to ensure smooth operation and a long
service life. Apply supplied grease to black shroud (highlighted
in yellow at right) then follow backing plate installation
instructions noted in section 6.
