3.0 Safety warnings
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. This bench grinder is designed and intended for
use by properly trained and experienced
personnel only. If you are not familiar with the
proper and safe operation of a bench grinder, do
not use until proper training and knowledge have
been obtained.
5. Do not use this bench grinder for other than its
intended use. If used for other purposes, JET
disclaims any real or implied warranty and holds
itself harmless from any injury that may result
from that use.
6. Always use safety glasses. Use the grinder’s eye
shields and spark guards. (Everyday eyeglasses
only have impact resistant lenses; they are NOT
safety glasses.) Also use face or dust mask if
cutting operation is dusty.
7. Wear proper apparel. Do not wear loose clothing,
neckties, rings, bracelets, or other jewelry which
may get caught in moving parts. Non-slip
footwear is recommended. Wear protective hair
covering to contain long hair.
8. Wear protective clothing such as apron or safety
shoes, where the grinding activity presents a
hazard to the operator.
9. Wear ear protectors (plugs or muffs) if the
particular work requires it.
10. Some dust created by power sanding, sawing,
grinding, drilling and other construction activities
contain chemicals known to cause cancer, birth
defects or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead based paint.
• Crystalline silica from bricks, cement and other
masonry products.
• Arsenic and chromium from chemically treated
lumber.
11. Your risk of exposure varies, depending on how
often you do this type of work. To reduce your
exposure to these chemicals, work in a well-
ventilated area and work with approved safety
equipment, such as face or dust masks that are
specifically designed to filter out microscopic
particles.
12. Do not operate this machine while tired or under
the influence of drugs, alcohol or any medication.
13. Make certain the switch is in the OFF position
before connecting the machine to the power
supply.
14. Make certain the machine is properly grounded.
15. Make all machine adjustments or maintenance
with the machine unplugged from the power
source.
16. Remove adjusting keys and wrenches. Form a
habit of checking to see that keys and adjusting
wrenches are removed from the machine before
turning it on.
17. 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.
18. 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.
19. Provide for adequate space surrounding work
area and non-glare, overhead lighting.
20. Keep the floor around the machine clean and free
of scrap material, oil and grease.
21. Keep visitors a safe distance from the work area.
Keep children away.
22. Make your workshop child proof with padlocks,
master switches or by removing starter keys.
23. Give your work undivided attention. Looking
around, carrying on a conversation and “horse-
play” are careless acts that can result in serious
injury.
24. Keep proper footing and balance at all times so
that you do not fall into or lean against the
grinding wheel or other moving parts. Do not
overreach or use excessive force to perform any
machine operation.
25. Disconnect grinder before servicing and when
changing abrasive wheels.
26. Use recommended accessories. The use of
improper accessories may cause risk of injury to
persons.
27. Turn off the machine before cleaning. Use a
brush to remove chips or debris — do not use
your hands.
28. Never leave the grinder running unattended. Turn
power off and do not leave machine until wheels
come to a complete stop.
