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.

6.1 GROUNDING INSTRUCTIONS
Read and understand the entire
contents of this manual before attempti ng setup or operation! Failure to comply may cause
serious injury.
5.0 Setup
Remove all crating and check for shipping damage.
Report any damage immediately to your distributor
and shipping agent. Do not discard any shipping
material until Pipe Notcher is set up and operating
properly.
Use hoist, forklift, or similar means to raise Pipe
Notcher using lifting ring on top. Straps and chains
must be properly rated for weight of Notcher.
The Pipe Notcher can be used in horizontal or
vertical position. Mount it to a stable surface with
appropriate fasteners (not provided). Make sure to
leave space around machine for pipe movement
and general maintenance.
Remove any protectant from the machine with a soft
cloth and a cleaner-degreaser or kerosene. Do not
allow solvents to contact painted or plastic areas.
6.0 Electrical connections
Electrical connections must be
made by a qualified electrician in compliance
with all relevant codes. This machine must be
properly grounded to help prevent electrical
shock and possible fatal injury.
This tool must be grounded. In the event of a
malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce
the risk of electric shock. This tool is equipped with
an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be
inserted into an appropriate outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
Improper connection of the
equipment-grounding conductor can r esult in a
risk of electric shock. Check with a qualified
electrician or service person if you are in do ubt
as to whether the outlet is proper ly grounded.
Do not modify the plug pr ovided w ith the tool –
if it will not fit the outlet, have a proper outlet
installed by a qualified electrician.
The conductor with insulation having an outer
surface that is green with or without yellow stripes is
the equipment-grounding conductor. If repair or
replacement of the electric cord or plug is
necessary, do not connect the equipment-grounding
conductor to a live terminal.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord
immediately.
The ESN-40 Pipe Notcher is ready to run at 230-volt
operation. This tool is intended for use on a circuit
that has an outlet that looks like the one illustrated
in Figure 6-1. The tool is intended for use with a
grounding plug that looks like the plug illustrated in
Figure 6-1. Make sure the tool is connected to an
outlet having the same configuration as the plug. No
adapter is available or should be used with this tool.
If the tool must be reconnected for use on a different
type of electric circuit, the reconnection should be
made by qualified service personnel; and after
reconnection, the tool should comply with all local
codes and ordinances.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the Pipe Notcher be
connected to a dedicated 15 amp circuit with a
circuit breaker or fuse. If connected to a circuit
protected by fuses, use time delay fuse marked “D”.
NOTE: Local codes take precedence over
recommendations.
Figure 6-1: grounding
6.2 Extension cords
The use of extension cords is discouraged; try to
position equipment within reach of the power
source. If an extension cord becomes necessary, be
sure it is 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 shows recommended size to use depending
on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.

7.0 Operation
Make sure pipe notcher is
properly lubricated before oper ating. Failure to
comply may cause damage to machine.
The Pipe Notcher is shipped with oil in the reduction
box. However, the operator should confirm this
before using the machine! See sect. 8.0.
1. Turn on machine.
2. Clean pipe end of any dirt, chips, burrs, etc.
3. Insert end of pipe into correct hole, determined
by nominal size of schedule 40 pipe (see Figure
7-1). NOTE: Insertonly one pipe at a time into the machine.
4. Continue to lightly press pipe into hole until it
slides farther in and is notched. Pull pipe out.
The scrap will fall to bottom of machine.
5. Remove pipe. It is now read y for saddling and
welding.
8.0 User-maintenance
Disconnect machine from
power supply before performing any
maintenance. Failure to comply may result in
serious injury.
1. It is recommended that the oil be replaced every
2,500 operating hours. Remove set screw to
drain (Figure 8-1).
Capacity - 2.0L. (approximate)
Recommended oil - see Table 2.
2. Remove cover and clean out any lingering chips
or debris around blade area, as needed.
3. Periodically check tightness of all screws.
