START-UP PROCEDURE
1. Plug the controller into a properly sized extention cord (see Safety).
2. Plug the extension cord into an adequate power supply.
3. Attach the control box safety tether to the operator’s wrist.
4. Move the FWD/REV toggle switch to the desired “forward” or “reverse” position.
(Figure 5A)
5. The operator should apply a light amount of pressure to the grinder handle to re-
lieve the initial torque created when starting the machine.
6. Move the power toggle switch to the “ON” position (Figure 5B).
SHUT-DOWN PROCEDURE
To turn the grinder off move the toggle switch to the “OFF” position.
ACCESSORY SET-UP
When grinding, down pressure relates to two aspects: (1) the amount of weight on the
machine, and (2) the surface area the weight is being distributed across.
• If tooling with a smaller segment is used, the amount of down pressure applied at
the point of contact is increased.
• Larger segments of tooling will decrease the amount of down pressure.
Down pressure will directly affect production rates and of profile achieved. If more down
pressure is desired, insert the tooling segments into two of the four magnetic pockets. Be
sure to insert the tooling into the magnetic pockets directly across from one another.
The machine is designed to run in forward or reverse for most applications:
• With the grinder switch in “forward,” the tooling should turn clockwise and the drum
should turn opposite (Figure 6).
• With the grinder switch in “reverse,” the tooling should turn counterclockwise and
the drum should turn opposite (Figure 7).
Note: PCDs and carbides can only be used in forward motion.
