  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 wear protective eye wear when 

operating machinery. Eye wear shall be impact 
resistant, protective safety glasses with side 
shields which comply with ANSI Z87.1 
specifications. Use of eye wear which does not 
comply with ANSI Z87.1 specifications could 
result in severe injury from breakage of eye 
protection. (Everyday eyeglasses only have 
impact resistant lenses; they are NOT safety 
glasses.) Use the grinder’s eye shields and 
spark guards. 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 sound 

exceeds safe levels. 

10. CALIFORNIA PROPOSITION 65 WARNING:

 

This product contains chemicals known to the 
State of California to cause cancer, or birth 
defects or other reproductive harm. 

11.  This product, when used for welding, cutting, or 

working with metal, produces fumes, gases, or 
dusts which contain chemicals known to the 
State of California to cause birth defects and, in 
some cases, cancer. (California Health and 
Safety Code Section 25249.5 et seq.) 

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, belt, or other moving parts. Do 
not overreach or use excessive force to perform 
any machine operation. 

25.  Disconnect grinder before servicing and before 

changing wheel, disc, or belt.
