  IMPORTANT SAFETY 

INSTRUCTIONS 

WARNING – To reduce risk of injury: 

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.  Do not operate this machine while tired or under 

the influence of drugs, alcohol or any medication. 

11.  Make certain the switch is in the OFF position 

before connecting the machine to the power 
supply. 

12.  Make certain the machine is properly grounded. 

13. Make all machine adjustments or maintenance 

with the machine unplugged from the power 
source. 

14.  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.  

15.  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. 

16.  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. 

17. Provide for adequate space surrounding work 

area and non-glare, overhead lighting. 

18.  Keep the floor around the machine clean and free 

of scrap material, oil and grease. 

19.  Keep visitors a safe distance from the work area. 

Keep children away. 

20.  Make your workshop child proof with padlocks, 

master switches or by removing starter keys. 

21. Give your work undivided attention. Looking 

around, carrying on a conversation and “horse-
play” are careless acts that can result in serious 
injury. 

22.  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. 

23. Disconnect grinder before servicing and when 

changing abrasive wheels.  

24. Use recommended accessories. The use of 

improper accessories may cause risk of injury to 
persons.  

25. Turn off the machine before cleaning. Use a 

brush to remove chips or debris — do not use 
your hands. 

26.  Never leave the grinder running unattended. Turn 

power off and do not leave machine until wheels 
come to a complete stop. 

27. Remove loose items and unnecessary work 

pieces from the area before starting the grinder. 

28.  Don’t use in dangerous environment. Don’t use 

power tools in damp or wet location, or expose 
them to rain. Don’t use this grinder in a 
flammable environment. Keep work area well 
lighted. 

29. Keep work area clean. Cluttered areas and 

benches invite accidents. 

30.  Use right tool. Don't force tool or attachment to 

do a job for which it was not designed.
