USER MAINTENANCE & TROUBLESHOOTING

If Your Orbot Micro Fails to Run
Be sure the machine is disconnected from the electrical supply before any inspection or maintenance is
performed. The motor is only for the voltage specified on the nameplate. Voltage should not vary more
than 10% over or under the voltage shown on the nameplate. Although the ORBOT MICRO is built to
last a lifetime, it can encounter problems from heavy wear and tear. All problems are repairable, and
can most often be repaired by a mechanically inclined technician or user.
1)
If your Orbot Micro fails to run, unplug it from the outlet or power source.
a) Check power cord plug for bent prongs that could be preventing proper contact with the outlet.
b) Check power cord for worn or cracked insulation. If these are noted,
DO NOT CONTINUE
TO OPERATE
tool.
IMMEDIATELY
contact your dealer to have tool repaired and serviced.
c) Check power source for blown fuses or open circuit breakers. Also verify that power source is
providing adequate voltage and current to safely operate your tool. Use a volt meter if able.
2)
If your Orbot Micro starts to arc, experiences a loss in torque, runs hot to the
touch or has stopped during operation:
a) Turn off and
DO NOT CONTINUE TO OPERATE
the tool. Continuing to use your tool may
cause further damage by creating a short circuit in the motor windings. Unplug the machine
from the outlet or power source, and proceed through the following steps or contact your
dealer to have your tool repaired and serviced:
3)
Clean tool of dirt, fiber, and other debris by blowing it out with compressed air.
a) This is recommended maintenance for every 8 hours of operation or as conditions warrant.
Pay attention to area around the carbon brushes’ contact with the motor, just inside the top
of motor cover. If used on carpets or with wool pads/bonnets, it is recommended to blow out
your tool after every use. If the tool should get wet, also blow out the underside of the tool.
If the tool has gotten wet, you may need to allow the tool to completely dry before you are
able to completely blow out all the fibers and other debris.
4)
Check the carbon brushes, brush holder and brush holder caps.
a) The carbon brushes are wear items and periodically will need
replacing (after 50 to 150 hour of use). Carbon brushes will
shut off the machine when needing replacing. Never operate
with chipped or cracked brush holder caps. Refer to the images
shown for good and worn parts. Since brushes are wear items,
we recommend that you keep a spare set of brushes. Please
note some specialty tools are required for replacing the brush
holders. Recommend to have your dealer perform this service.
5)
Inspection of the brush holder caps.
a)
WARNING:
Never operate machine with chipped or otherwise damaged brush holder caps.
b) Be sure power cord is disconnected. Use a screwdriver to remove damaged brush holder cap,
carbon brush and spring. Wipe threads with a cotton Q-tip on inside of brush holder cleaning
any foreign matter. Replace carbon brush, spring and screw on a new brush cap.
