F.A.Q.

First refer to the instruction manual for guidance. If this is a bigger floor model that is hard wired to a power source (electric or gas), contact your licensed professional for advice and possible service. If this is a bench top model that is plugged into a wall outlet, then check the power source. Make sure all connections are secure. If the device still does not turn on, check for a fuse, and replace it if need be. Also, you can check the on/off switch for any lose terminals or possible failure. You should consult with a licensed electrician. A primary reason for denture processing equipment failure is a lack of proper cleaning and maintenance. In many cases the submersible copper or stainless-steel heating elements are not cleaned or maintained and therefore debris builds up over time causing these parts to fail. If this happens, you can try to clean the unit with non-abrasive cleaners.  You may have to have the parts replaced by a professional. 

Replacing a model trimmer wheel requires the use of special wrenches that can be purchased by Handler. The part number is P31-10 and can be purchased at this link: https://www.handlermfg.com/product/p31-10-wrenches-set-of-2/. First, unplug the unit disconnecting it from the power source. Remove the two Phillip head screws behind the front housing that hold the motor cover in place. Lift the motor cover up. Open the front door of the model trimer to expose the wheel. Position the straight wrench over the notched brass hub behind the housing. Position the angled wrench on the brass nut in front of the wheel and turn counterclockwise. Normally there is plaster sediment build up making it hard to loosen. You may need some type of lubricant to help loosen the nut. Follow the same steps in reverse to install the new wheel.

There is a clog in the water line at some point. Close off your water supply and unplug the unit before any service. Check the source from the wall first. Then check the line coming into the model trimmer.  If there is a solenoid valve installed, check to make sure it is functioning properly. Check the black fitting at the bottom of the model trimmer. Remove the tube from the barbed fitting underneath the rear housing. Ream it out with an appropriate tool or bottle brush. Remove the set screw on the bottom of the black fitting and do the same. Ream the entire length of the spray tube. Then, using a paper clip or think prod, clean out each of the 12 holes in the spray tube.  Make all connections secure again and power up the unit. 

Always operate at the low speed before flipping to high speed.  If you flip the unit directly onto high speed constantly, you will damage the internal windings.  Check the on/off switch for proper connection. Unplug the unit from its power source. Turn the motor on its backside and remove the base plate cover. Secure all connections.  If connections are secure, then the switch needs to be replaced. The part P26-15B red rocker switch can be purchased at this link here. https://www.handlermfg.com/product/p26-15b-rocker-switch-2-speed/.  If you have replaced the switch and it still does not operate, then the internal centrifugal switch has malfunctioned.  Contact Handler customer service at customerservcie@blackstoneind.com to have the unit sent in for flat rate repair.
