Operation
WARNING:
Do not operate this grinder-buffer until you are sure that you are completely familiar with the safe operation
of the grinder-buffer, all accessories and safety equipment. Improper use can lead to severe injury. This
manual defines proper use of this equipment. Before using this equipment for any other use, please seek
expert advise if you do not understand any procedure or operation concerning this grinder-buffer or this
manual.
WARNING:
Always use safety glasses with side shields (or full face shield) when operating grinder. Do not use ordinary
eyeglasses. Also use face or dust mask if cutting operation is dusty.
WARNING:
When starting a grinder for the first time, or after installing a replacement wheel or belt, it is most important
that the operator stand aside for at least one minute of rotation at full speed. This is the correct practice
since belts and wire wheels can disintegrate if they have received damage during shipping or handling.
WARNING:
Be sure the system is properly grounded before applying power. Do not apply power before you ensure that
grounds are connected. Electrical shock can cause serious or fatal injury. Follow the National Electrical Code
(NEC) and local codes for the safe installation of this equipment.
Power On Procedure
1.
Be sure the On-Off switch is in the Off position, and the wire wheel and belt grinder move freely.
2.
Connect the AC power cord to a properly grounded 115VAC receptacle.
3.
Put on full face shield.
4.
Stand to either side of the grinder-buffer and place the On-Off switch in the On position.
Wait at least one full minute of grinder rotation to verify that no pieces of the wire wheel or belt are being thrown
from the grinder. A damaged wheel or belt can disintegrate and must be replaced.
5.
Place the On-Off switch in the Off position to stop grinder-buffer operation.
Wire Wheel Operation
Always use guard and eyeshield. Operating the grinder-buffer without the guard and eyeshield or with damaged
guard and eyeshield must not be attempted because of the hazard this introduces.
Maintain 1/8 or less clearance between tool rest and wheel. This clearance is necessary in preventing the work piece
from becoming wedged between the wheel and tool rest and restricting nip areas in the machine.
Buff on face of brush only.
1.
Put on full face shield.
2.
Place the On-Off switch in the On position. Grinder-buffer should come up to speed smoothly and without
vibration. If grinder-buffer does not, turn off grinder-buffer immediately and determine reason.
3.
Place work piece on tool rest and buff the work piece on the wire brush face only.
4.
Place the On-Off switch in the Off position to stop grinder-buffer operation.
Belt Grinder Operation
Always use guard and eyeshield. Operating the grinder-buffer without the guard and eyeshield or with damaged
guard and eyeshield must not be attempted because of the hazard this introduces.
Ensure the correct belt is installed so the Belt Lap faces the correct direction, see Figure 1.
1.
Put on full face shield.
2.
Place the On-Off switch in the On position. Grinder-buffer should come up to speed smoothly and without
vibration. If grinder-buffer does not, turn off grinder-buffer immediately and determine reason.
3.
Belt grind the work piece using one of the methods described.
4.
Place the On-Off switch in the Off position when done.
Several methods for belt grinding can be used: see Figure 1.
1.
Platen Grinding (Horizontal or Vertical)

2.
Disc Grinding When possible, remove belt (to reduce wear) when disc grinding.
Use only grinding area indicated in Figure 3.
a.

Be sure the platen is properly adjusted, see Maintenance section of this manual.
Work of any length can be surfaced using the platen. For example the sawn edges of wood from short
pieces up to lengths of several meters.
Tool and cutter sharpening is a simple task and there is less chance of burning the work edges.
When using the optional table, lengths and angles are easy to adjust.
Dressing end grain flat and square has always been a difficult task but now it is a simple and quick
operation, making perfect joints possible. A rubber cleaning stick should be used regularly to prevent
built up of wood resin.
Three options are available in abrasive discs. 1. Self-Adhesive. 2. Fur backed - which must be used with an
optional hook and loop backing pad. 3. Plain paper or cloth backed disc which must be attached with a
contact adhesive. When changing a disc pad, remove all remaining adhesive from the disc with solvent
(acetone or lacquer thinner). Do not use household cleaners.
Figure 3 Disc Grinding
Use only the surface indicated so grinding is in the
downward direction and the force against the work
piece is downward against the table.
