    Maintenance and troubleshooting. Note. When conducting maintenance, disconnect the machine from the electricity and the air supply. General. Keep your machine clean. At the end of each day, clean the machine. If dust is not removed, it will cause rust. In general, we recommend that you only use a Teflon-based lubricant.
  • Page 33 Bearing lubrication. The bearings need to be greased. There are several grease points, as shown in the photographs below. It is recommended that the machine be greased after every 40 hours of operation. Greasing the bearings will flush out dust from the seals. After greasing, wipe off any excess. A grease gun extender is supplied to ease access to the bearings.
  • Page 34 Sanding belt non-contact air sensor. There are holes in the sensor for the air to escape through. The holes should be checked regularly, and if they block, they must be cleaned. If the holes block, the belt will not track correctly on the rollers. Ceramic rollers.
  • Page 35 Pressure roller adjustment. Pressure roller adjusting studs & nuts There are four pressure rollers: two on the infeed side and two on the outfeed side of the contact roll. The pressure rollers come factory set but may need to be adjusted during the life of the machine or certain applications.
  • Page 36 of the material and other factors. Experimentation will be required to achieve the correct setting. It is suggested that setting the pressure rollers to 0.020" to 0.030" is a good starting point. Never set the pressure rollers level or higher than the sanding roller (contact roll), as this may result in injury from stock slippage.
