1.0 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 pipe notcher 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 pipe notcher, do
not use it until proper training and knowledge
have been obtained.

5. Do not use this pipe notcher 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 ANSI Z87.1 approved safety
glasses or face shield while using this machine.
(Everyday eyeglasses only have impact
resistant lenses; they are not safety glasses.)

7. Keep hands away from notching holes when
machine is connected to power.

8. Make certain the machine is properly grounded.

9. Before operating the machine, remove tie,
rings, watches, other jewelry, and roll sleeves
up past the elbows. Remove all loose clothing
and confine long hair.

10. Keep the floor around the machine clean and
free of scrap material, oil and grease.

11. Keep machine guards in place at all tim es when
the machine is in use. If removed for
maintenance purposes, use extreme caution
and replace the guards immediately upon
completion of maintenance.

12. Make all machine adjustments or maintenance
with machine unplugged from power source.

13. Use the right tool. Do not force a tool or
attachment to do a job that it was not designed
to do.

14. Make certain the switch is in the OFF position
before connecting the machine to the power
supply.

15. Give your work undivided attention. Looking
around, carrying on a conversation and "horse­play" are careless acts that can result in serious
injury.

16. Keep visitors a safe distance from the work
area. Keep children away.

17. Make your workshop child proof with padlocks,
master switches or by removing starter keys.

18. Maintain a balanced stance at all times so that
you do not fall onto moving parts. Do not
overreach or use excessive force to perform
any machine operation.

19. Use recommended accessories; improper
accessories may be hazardous.

20. 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.

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 well­ventilated area and work with approved safety
equipment, such as face or dust masks that are
specifically designed to filter out microscopic
particles.

21. Do not operate this machine while under the
influence of drugs, alcohol or any medication.

22. Keep tools sharp and clean for safe and best
performance.

23. Provide for adequate space surrounding work
area and non-glare, overhead lighting.

24. Use only JET factory authorized replacement
parts and accessories; otherwise, the warranty
and guarantee are null and void.

25. Use proper extension cord. Make sure your
extension cord is in good condition. When using
an extension cord, be sure to use one heavy
enough to carry the current your product will
draw. An undersized cord will cause a drop in
line voltage resulting in loss of power and
overheating. Table 1 (sect. 6.2) shows correct
size to use depending on cord length and
nameplate ampere rating. If in doubt, use the
next heavier gage. The smaller the gage
number, the heavier the cord.
