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.
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 the 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. Special electrical precautions should be taken
when working on flammable materials.
7. Avoid accidental starts by being sure that the
start switch is in the “OFF” position before
plugging in the machine.
8. Never leave the machine running while
unattended. The machine shall be shut off
whenever it is not being used.
9. Disconnect the electrical power before servicing,
whenever changing accessories or when general
maintenance is done on the machine.
10. 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.
11. If there is any risk of tipping or sliding, the
machinery must be anchored to the floor.
12. 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.
13. Never brush chips away while the machine is in
operation.
14. Keep work area clean. Cluttered areas invite
accidents.
15. Remove adjusting keys and wrenches before
turning the machine on.
16. Use the right tool. Don’t force a tool or
attachment to do a job it was not designed for.
17. Use only recommended accessories and follow
manufacturer’s instructions pertaining to them.
