  Safety Warnings 

3.1

  General Cautions 

-   Misuse of this machine can cause serious injury. 

-   For safety, the machine must be set up, used and 

serviced properly. 

-   Read, understand and follow the instructions in the 

Operating Instructions and Parts Manual which was 
shipped with your machine. 

When setting up the machine: 

-   Always avoid using the machine in damp or poorly 

lighted work areas. 

-   Always be sure the machine is securely anchored 

to the floor or the work bench. 

-   Always keep the machine guards in place. 

-  Always put the start switch in the “OFF” position 

before plugging in the machine. 

When using the machine: 

-  Never operate the machine with safety guards 

missing. 

-   Always wear safety glasses with side shields (See 

ANSI Z87.1)  

-   Never wear loose clothing or jewelry. 

-  Never overreach; you may slip and fall into the 

machine. 

-   Never leave the machine running while unattended. 

-   Always shut the machine off when not in use. 

When servicing the machine: 

-  Always unplug the machine from the electrical 

power before servicing. 

-  Always follow the instructions in the Operating 

Instructions and Parts Manual when changing 
accessory tools or parts. 

-   Never modify the machine without consulting JET. 

You — the stationary power tool user — hold the key 
to safety. 

Read and follow these simple rules for best results 
and full benefits from your machine. Used properly, 
JET machinery is among the best in design and 
safety. However, any machine used improperly can 
be rendered inefficient and unsafe. It is mandatory 
that those who use our products be properly trained in 
how to use them correctly. They should read and 
understand the Operator’s and Parts Manual as well 
as all labels affixed to the machine. Failure in 
following all of these warnings can cause serious 
injuries. 

3.2

  General Machinery Warnings 

1. 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 the breakage of the 
eye protection. 

2.  Wear proper apparel. No loose clothing or 

jewelry which can get caught in moving parts. 
Rubber soled, nonslip, footwear is 
recommended for best footing. 

3.  Do not overreach. Failure to maintain a proper 

working position can cause you to fall into the 
machine or cause your clothing to get caught 
— pulling you into the machine.  

4.  Keep guards in place and in proper working 

order. Do not operate the machine with the 
guards removed. 

5.  Avoid dangerous working environments. Do 

not use stationary machine tools in wet or 
damp locations. Keep work areas clean and 
well lit. 

6.  Avoid accidental starts by being sure that the 

start switch is in the “OFF” position before 
plugging in the machine. 

7. Never leave the machine running while 

unattended. The machine shall be shut off 
whenever it is not being used. 

8. Disconnect the electrical power before 

servicing, whenever changing accessories or 
when general maintenance is done on the 
machine. 

9.  Maintain all machine tools with care.  Follow all 

maintenance instructions for lubricating and 
the changing of accessories. No attempt shall 
be made to modify or have makeshift repairs 
done to the machine. This not only voids the 
warranty but also renders the machine unsafe. 

10. If there is any risk of tipping or sliding, the 

machinery must be anchored to the floor. 

11. Secure your work. Use clamps or a vise to 

hold your work, when practical. It is safer than 
using your hands and it frees both hands to 
operate the machine. 

12.  Never brush chips away while the machine is 

in operation. 

13. Keep work area clean. Cluttered areas invite 

accidents. 

14. Remove adjusting keys and wrenches before 

turning the machine on.
