After wet operation, wash bottom of machine thoroughly, failure to do so may
result in damaged bearing seals.!
DO NOT use any sharp object or abrasive pad to clean the bearing shields. This
can compromise the bearing seal.

!
• Check all strain reliefs and make sure they are tight. (Strain reliefs are the
plastic nuts that secure the wires that come out of the handle and VFD.)
• Remove the pad drivers and inspect the threads to make sure there are no
signs of cross-threading or stripping. Remove excess thread locking
compound from bolts using a wire brush or by washing the bolts in a solvent.
• Clean and lubricate wheels.
• Using an extremely light abrasive pad, remove any topical rust from the shafts.
TROUBLESHOOTING
!
Machine will not turn on.
Check all power connections. Make sure
the source power meets the machine’s
minimum power requirements (see
Power Cord Minimum Requirements
p. 5).
• Plug in the machine.
• Check to see if any breakers or fuses are tripped or blown.
• Check to see the handle activation lever is not depressed.
• Have a qualified electrician test the source power to see if it meets
the machine’s minimum power requirements.
Machine turns on but will not
start.
Check the VFD display for error codes
(see Appendix p. p.19).
• If no error code is displayed, check if the handle wire is plugged
into the machine.
• If the VFD error code is “voltage range,” have a qualified
electrician test the source power and make the necessary
adjustments to the wiring to supply the machine with its required
input power.
Machine runs for a short time
and then shuts down.
Check the circuit breaker to see if it is
tripped or the fuse if it is blown.
• Check to make sure that the power source has the appropriately
sized breaker or fuse to meet the machine’s minimum power
requirements.
• Make sure the generator meets the machine’s minimum power
requirements.
• Have an electrician perform a voltage test while the machine is
under load to see if the voltage drops below the machine’s
minimum power requirements.
Pad drivers are not turning or
only one pad driver is
turning.
Disconnect the power and tilt the
machine back. Spin one pad by hand.
• If the pad turns independently, replace the secondary belt. Go to
www.werkmaster.com/support.
• If all pad drivers turn but the motor fan does not turn, replace the
primary belt. Contact technical support: 866.373.9375.
Not all discs are grinding the
floor.
Disconnect the power and tilt the
machine back. Visually inspect each pad
driver height against the adjacent pad
driver.
• Make sure all pad drivers are seated properly on the shafts.
• Make sure grinding / polishing / sanding media is seated properly
on the pad drivers.
• Make sure grinding / polishing / sanding media is worn evenly and
change out any media if uneven.
