8. All three phase electrical installations must include a magnetic starter. Magnetic starters protect motors
from “double phasing”, overheating, etc. thereby reducing the risk of damage to the equipment and/or
fire hazard to your facility. Three phase motors are not warranted if used without a magnetic starter or
other suitable device.
Functional operating instructions for the Model 1050 buffer
The Model 1050 was fully tested and verified to comply with requirements prior to shipping from the factory.
No adjustments should be necessary. You should perform the following steps:
1. With the machine securely bolted to its table, pedestal, and/or floor point connect the AC power to its
source.
2. Insure the buffing wheels are firmly tightened to the spindle. A finishing wheel running in reverse
rotation can unscrew from the spindle, creating a serious personnel safety hazard. Insure that the Model
1050 spindle operates CCW when viewed from the right side of the machine. The right spindle has a
right-hand thread.
3. Your model 1050 has been shipped to you with 1 cap plug on each end of the spindle it is very important
that once you have selected the wheel you will be using on your machine that you cut the plug to the
size of the exposed thread. Failure to do so may expose the operator to risk of injury should clothing or
loose objects become snagged on the exposed area.
4. Engage the motor. The wheel should rotate smoothly in a CCW direction with the front face of the
finishing wheel moving toward the floor. If either of these conditions are not met turn the machine OFF
immediately.
5. If the Model 1050 runs in reverse direction you must correct this by changing the main drive motor
rotation direction. FIRST DISCONNECT THE MACHINE FROM ITS AC POWER SOURCE. A
COMPETENT ELECTRICIAN SHOULD PERFORM ALL ELECTRICAL WORK ON THE
MODEL 1050.
All single phase Model 100 buffers are set up for correct rotation at the factory. The phasing of your “in-
house” electric service will effect three phase Model 1000 rotation.
If your Model 1050 is equipped with variable speed control the wheel speed can be adjusted using the speed
control that will be mounted on the motor or on a separate control box.
Maintenance
FIRST DISCONNECT THE MACHINE FROM ITS AC POWER SOURCE.
Every thirty days or if the drive belt slips check the drive belt tension To adjust the belt tension:
• Remove the two screws that secure the aluminum cover plate on the right side of the main casting.
• Loosen (do not remove) the two elastic nuts (use a 9/16 inch socket) inside the main frame near the
rear drive pulley. Use care not to nick or otherwise damage the pulley. The pulley has a series of
shallow groves that drive the Micro-V flat drive belt if so equipped. Any damage to the groves will
shorten belt life significantly.
• Pull the main frame forward in respect to the motor. The frame will slide across the motor face with
the above elastic nuts loose.
• The belt is properly tensioned when a force of approximately 5 pounds will deflect the belt
approximately ¼ inch near the center of the belt track.
• Tighten the two elastic nuts and reinstall the cover plate.
• Vacuum or otherwise remove dust and debris build-up regularly from the machine.
