in damage to the machine

Arbor & Motor Installation
•
Mount the Arbor to a solid work surface or bench using four 1/4” diameter bolts (length of bolts will depend
on the bench top). Note: This arbor is designed to run with a 1/3 HP, 1725 RPM motor.
•
Install drive pulley on motor. We suggest using a 2” x 1/2” pulley for most operations.
•
Secure motor to the bench or work surface allowing for belt length and adjustment.
•
Install belt and adjust motor to obtain correct belt alignment and tension. Do not overtighten the belt as this
can lead to excessive noise and premature bearing wear.

Operation & Maintenance
•
Mount wheels securely using appropriate anges. For narrow wheels on the NS8, use the aluminum spacer
between the retaining ring and the ange. Tighten shaft nuts securely.
•
To mount wheels on the NS8 Long Shaft, use shaft nuts on either side of the wheel anges.
•
Use a water drip system or pump to provide coolant to the wheels. A splash shield may be required.
•
When grinding stone using Silicon Carbide wheels, and arbor speed of 1725 RPM gives good results.
•
For polishing, reduce the arbor speed by using the larger pulley on the arbor. Proper polishing speed depends
upon the material but can best be accomplished at speeds from 850 - 1725 RPM as needed.
•
The Arbor should be cleaned periodically with a damp cloth and the belt checked for wear.
•
Replace damaged belt or bearing if required.
