TROUBLESHOOTING GUIDE

Trouble     Probable Cause Remedy
Sander will not start No incoming power Check that the sander is connected to power, fuses are not blown or circuit breakers are not tripped
  Low voltage Check the voltage at the power source
  Loose wiring Inspect and remedy any loose connections on sander
  Start switch is defective Replace the start switch. Contact Apex representative for parts and service.
  Motor is defective Replace the motor. Contact Apex representative for parts and service.
The sanding belt clogs too quickly Grit of the sanding belt is too fine Choose a larger grit of sanding paper
  Too much material is being sanded off Reduce the amount of material being removed
Sanding belt will not run, or slips on the roller Emergency stop button is engaged Disengage the stop button
  Limit switches are activated Position the sanding belt so it is between the limit switches
  Insufficient air pressure causing the belt to slip on rollers Make sure air pressure regulator is set at 75 to 80 PSI (Refer to page 9 in the EZ Sander Manual)
  Dust or debris on the conveyor rollers Clean the conveyor rollers
Sanding belt keeps tripping limit switch Tracking adjustment/oscillation is not correct Set tracking correctly
Watch video on tracking the abrasive belt
  Dust covering the photo eye Check and clean dust from the photo eye
Machine takes too long to stop after the emergency switch is activated Air pressure is too low Set air pressure to 75 to 80 PSI
  Brake pads are worn Replace brake pads. Contact Apex representative for parts and service.
Grinding noise when brake is activated Brake pads are worn Replace brake pads (rotor may need turning also). Contact Apex representative for parts and service.
Too much rounding Too much material is being removed, too tightly Reduce the amount of material making the contact drum press being removed
The front end of the stock is thinner than the rear Rear hold down roller is too low in relation to the contact drum Raise the rear pressure bar (Refer to pages 16-17 in the EZ Sander Manual)
The rear end of stock is thinner than the front Front hold down roller is too low in relation to the contact drum Raise front pressure bar (Refer to page 16 in the EZ Sander Manual)
Uneven thickness between the left and right sides of the workpiece Table is not positioned correctly in relation to the contact drum Adjust table until it is parallel left to right (Refer to pages 17-18 in the EZ Sander Manual)
  Front hold down roller is not in the correct position in relation to the contact drum Adjust the front hold down roller so that it is parallel (Refer to page 16 in the EZ Sander Manual)
  Conveyor belt is worn Replace the conveyor belt. Contact Apex representative for parts and service.
Uneven thickness between the front and rear ends of the workpiece Feed rate is too high Reduce the feed rate (Refer to page 16 in the EZ Sander Manual)
  Too much stock removal Reduce the amount of material being removed
  Grit of sanding belt is too fine Use a larger grit sanding belt
  Unequal position of the hold down rollers Adjust the hold down roller to produce pressure on the stock
  Table is not parallel front to back Adjust the table until it is parallel front to back (Refer to pages 17-18 in the EZ Sander Manual)
Workpiece slips on on conveyor belt There is not enough pressure between the hold down roller and the workpiece Increase pressure between the hold down roller and the workpiece
  There is too much dust or debris on the conveyor belt Clean the conveyor belt with compressed air
  Rear pressure bar is too low, halts the work piece Raise the rear hold down roller until the proper contact is achieved
Straight strip of notches or grooves in the workpiece Hold down roller is dirty Clean the hold down rollers
  Contact drum is scratched Replace the contact drum. Contact Apex representative for parts and service.
“Snake” marks on workpiece Local damage to the sanding belt Replace the sanding belt
Watch video on replacing sanding belt
Straight parallel running stripes over the entire width of the workpiece Joint of the sanding belt is too thick or is open Repair joint or replace the sanding belt
