Warni and understand the entire owner’s manual before attempting assembly or operation.
1. Read and understand the entire owner's manual before attempting assembly or operation.
2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with
all of these warnings may cause serious injury.
3. Replace warning labels if they become obscured or removed.
4. Do not use this grinder for other than its intended use. If used for other purposes, Baileigh Industrial
disclaims any real or implied warranty and holds itself harmless from any injury that may result from
that use.
5. Always use the grinder’s eye shields. In addition, wear ANSI Z87.1 approved safety glasses, or a face
shield. (Everyday eyeglasses only have impact resistant lenses; they are NOT safety glasses.)
6. Before operating grinder, remove tie, rings, watches and other jewelry, and roll sleeves up past elbows.
Do not wear loose-fitting clothing. Confine long hair.
7. Wear protective clothing such as apron or safety shoes, where the grinding activity presents a hazard
to the operator.
8. Wear ear protectors (plugs or muffs) if the particular work requires it.
9. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.
10. Make certain the switch is in the OFF position before connecting the machine to the power supply.
11. Make certain the machine is properly grounded.
12. Make all machine adjustments or maintenance with the machine unplugged from the power source.
13. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting
wrenches are removed from the grinder before turning it on.
14. Keep safety guards in place at all times when the machine is in use. If removed for maintenance
purposes, use extreme caution and replace the guards immediately after completion of maintenance.
15. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should
be carefully checked to determine that it will operate properly and perform its intended function. Check
for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other
conditions that may affect its operation. A guard or other part that is damaged should be properly
repaired or replaced.
16. Provide for adequate space surrounding work area and non-glare, overhead lighting.
17. Keep the floor around the machine clean and free of scrap material, oil and grease.
18. Keep visitors a safe distance from the work area. Keep children away.
19. Make your workshop child proof with padlocks, master switches or by removing starter keys.
20. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are
careless acts that can result in serious injury.
21. Maintain a balanced stance at all times so that you do not fall into the tool or other moving parts. Do
not overreach or use excessive force to perform any machine operation.
22. Disconnect grinder before servicing and when changing abrasive wheels.
23. Use recommended accessories. The use of improper accessories may cause risk of injury to persons.
24. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris — do
not use your hands.

7
25. Never leave the grinder running unattended. Turn power off and do not leave machine until wheels
come to a complete stop.
26. Remove loose items and unnecessary work pieces from the area before starting the grinder.
27. Don’t use in dangerous environment. Don’t use power tools in damp or wet location or expose them to
rain. Keep work area well lighted.
28. Inspect abrasive wheels for cracks or other forms of damage. Perform a “ring test” to check wheel
integrity (see section 6.10). Do not use a faulty or damaged wheel.
29. Verify that maximum RPM of abrasive wheels is compatible with speed of grinder.
30. Allow abrasive wheels to reach full RPM before starting the grinding operation.
31. Do not crowd the work so that the wheels slow.
32. Tool rest should be adjusted less than 1/8” from wheel surface.
33. Do not grind on side of wheel; do all work on the grinding face or edge near the tool rest.
34. Do not grind aluminum or magnesium, as these may pose a fire hazard.

1.0 Introduction
This manual is provided by Baileigh Industrial covering the safe operation and maintenance procedures for
a Model BBG-8 Bench Grinder. This manual contains instructions on assembly, safety precautions, general
operating procedures, maintenance instructions and parts breakdown. This machine has been designed
and constructed to provide consistent, long-term operation if used in accordance to instructions set forth in
this manual.
If there are any questions or comments, please contact either your local supplier or Baileigh Industrial.

2.0 Description
The Baileigh Industrial BBG-8 Bench Grinder is designed primarily for woodworkers; the slow speed is
optimal for grinding and sharpening common tool steels – lathe turning chisels, gouges, knives, plane irons,
carving tools, and more. Abrasive wheels are protected by cast iron guards. The large tool rests are
adjustable, with a tilt angle scale and incised lines to help align tools square to the wheel. A steel spark
guard and plexiglass eye shield provide safety (personal eye protection is still required). Rubber foot pads
prevent sliding. Alternatively, mounting holes are provided in the base for securing the unit to a bench or
stand. Heavy-duty machined flanges keep the grinding wheel true and reduce runout.
The operator is encouraged to familiarize him/herself with ANSI B7.1 – Safety Requirements for Use, Care
and Protection of Abrasive Wheels.
Retain this manual for future reference. If the grinder transfers ownership, the manual should accompany
it.
Read and understand the entire contents of this manual before attempting
assembly or operation! Failure to comply may cause serious injury!
