7. Engage the motor by placing the Start/Stop switch to Start. The belt must rotate smoothly in a counter-clockwise (CCW) direction
a.
If the abrasive belt does not remain centered on the contact wheel while the belt is moving use the tracking adjustment
on the upper left side of the machine to track the belt to the center of the contact wheel. Turning this will cause the belt to
track to the right and to the left. See figure 3.4
about the machine wheel belt path. If either of these conditions are not met immediately turn the machine OFF.
b. If the belt runs in reverse (up from the floor, or CW) correct this by changing the main drive motor rotation direction.
Disconnect the machine from its AC electrical power and have a competent electrician:
1) Reverse the motor direction of a three-phase motor by reversing any two legs of the input power lines.
2) Reverse the motor direction of a fixed speed single phase motor by reversing leads 5 and 8 found within the metal
wiring box located on the motor, or as otherwise instructed on the actual motor label.
3) To reverse variable speed models consult the documentation that was supplied with the motor controller, or call
the Burr King factory for assistance.
If the abrasive belt tensions, and tracks properly, but the machine has excessive vibration, turn the machine OFF and call the Burr
King factory for assistance.
Burr King Manufacturing also produces several accessories that are designed to work with your machine. Accessories designed to
sharpen lawn mower blades to small radius contact or internal grinding. We also offer an adapter to allow the user to run wheels in
place of the contact wheel. For more information on these accessories contact your local dealer or the Burr King factory directly.
Additional Information-
•
Every thirty days apply light machine oil to tracking assembly. Two drops of oil is sufficient.
Maintenance of the model X400
•
Every thirty days check the drive belt tension. If you can hear the belt “slap” the frame when the drive motor starts, the belt may
require re-tensioning. Do this by loosening the two nuts that secure the motor to the belt guard and slide the guard forward. Do
not over tighten the belt. Doing so will shorten the life of the machine bearings. Tighten the two nuts.
•
Routinely inspect the machine for loose hardware. Tighten as required.
•
Daily vacuum or otherwise remove dust and debris build-up from the machine and the machine belt track.
•
Verify proper tracking of the belt by rotating the tracking knob. If belt does not track while the machine is running it may be that
the bolt that holds pressure against the tracking knob is loose. Using a 5/16 allen and a 9/16” wrench adjust the amount of
pressure. Conversely if the tracking adjustment is too stiff loosen the bolt. If excess grinding dust has accumulated it may be
necessary to remove the tracking knob and clean the shaft and the aluminum housing. Reassemble using graphite or light
machine oil.
There are no other maintenance actions required. All bearings are sealed for life and require no additional lubrication.
