!
Disconnect power before performing any maintenance, cleaning, or repair
to your machine.
After wet operation, wash bottom of the 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 seals.
This can compromise the bearing seals.
• Wipe down the machine after every job.
• Gently remove dirt and debris from the pad driver.
• Check grommets and replace if necessary.
• Vacuum, wash and thoroughly dry the underside of the machine.
• Inspect the plug ends for signs of carbon deposits and arcing.
• Check all fasteners and tighten if necessary.
• Inspect the handle wires for damage.
• Blow off the VFD heat sink with compressed air.
• Using a soft scrub pad, remove any excess dirt build-up from the bottom
plate and back side of the pad drivers.
• Inspect bearing seals around shaft for any wear or damage.
• 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. Reapply blue thread locking compound (Loctite 243) and reinstall
pad drivers. Make sure bolts are tight.
