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 the warning labels if they become
obscured or removed.
4. This cold saw 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 cold saw, do not use until
proper training and knowledge have been
obtained.
5. Do not use this cold saw 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.
7. Before operating this cold saw, remove tie,
rings, watches and other jewelry, and roll
sleeves up past the elbows. Remove all loose
clothing and confine long hair. Non-slip
footwear or anti-skid floor strips are
recommended.
8. Wear ear protectors (plugs or muffs) during
extended periods of operation.
9. CALIFORNIA PROPOSITION 65 WARNING:
This product contains chemicals known to the
State of California to cause cancer, or birth
defects or other reproductive harm.
10. 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.)
11. Do not operate this machine while tired or under
the influence of drugs, alcohol or any
medication.
12. Make certain the switch is in the OFF position
before connecting the machine to the power
supply.
13. Make certain the machine is properly grounded.
14. Make all machine adjustments or maintenance
with the machine unplugged from the power
source.
15. 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.
16. 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
maintenance is complete.
17. Make sure the abrasive saw is firmly positioned
on a secure foundation.
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 “horseplay” are careless acts that can result in serious
injury.
24. Maintain a balanced stance at all times so that
you do not fall or lean against the blade or other
moving parts. Do not overreach or use
excessive force to perform any machine
operation.
25. Use the right tool at the correct speed and feed
rate. Do not force a tool or attachment to do a
job for which it was not designed. The right tool
will do the job better and more safely.
26. Only use an abrasive disc that is suited to the
work being done.
2
27. Do not make a cut which exceeds the capacities
of the abrasive saw as shown in the
specifications section of this manual.
28. Use recommended accessories; improper
accessories may be hazardous.
29. Maintain tools with care. Keep blades sharp and
clean for the best and safest performance.
Follow instructions for lubricating and changing
accessories.
30. Make sure the work piece is securely clamped
to the table. Never use your hand to hold the
work piece.
31. Make sure blade is not contacting workpiece
when machine is started.
32. Turn off the machine and disconnect from
power before cleaning. Use a cloth or brush to
remove chips or debris — do not use bare
33. Do not stand on the machine. Serious injury
could occur if the machine tips over.
34. Never leave the machine running unattended.
Turn the power off and do not leave the
machine until it comes to a complete stop.
35. Remove loose items and unnecessary work
pieces from the area before starting the
machine.
36. For circuits which are far away from the
electrical service box, the wire size must be
increased in order to deliver ample voltage to
the motor. To minimize power losses and to
prevent motor overheating and burnout, the use
of wire sizes for branch circuits or electrical
extension cords according to Table 1 (sect. 6.3)
is recommended.

Read and understand all
assembly instructions before attempting
assembly. Failure to comply may cause serious
injury.
5.0 Setup and assembly
5.1 Shipping contents
Carton contents
1 Abrasive saw
1 Material stop assembly
1 Open-end wrench, 32/36mm
1 Hex wrench, 8mm
1 Operator’s manual
1 Product registration card
5.2 Tools required for assembly
8mm hex wrench (provided)
21 and 24mm (or adjustable) wrench
5.3 Unpacking and cleanup
1. Inspect contents for shipping damage. Report
damage, if any, to your distributor. Do not
discard shipping materials until saw is installed
and running properly.
2. Compare contents of shipping carton with the
contents list in this manual. Report shortages, if
any, to your distributor.
5.4 Location
Locate the machine on a solid, level floor, preferably
concrete. Area should have good overhead lighting
and ventilation, with enough room for loading and
offloading of stock and general maintenance.
Secure machine to floor using lag screws (not
provided) or similar means through the provided
holes in base.
5.5 Operating handle
Refer to Figure 5-1.
1. Install operating handle (A) into threaded hole.
Rotate it a good distance into hole, and make
sure final orientation of handle grip is in
comfortable position for operator.
2. Secure operating handle by tightening hex nut
(B) against saw head.
Figure 5-1 (AB-12 shown)
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.
The AB-12 and AB-14 Abrasive Saws are rated for
3-phase, 230/460-volt power, prewired 230V. They
are not supplied with a plug. You may either install
a proper 230V UL/CSA listed plug, or “hardwire” the
machine directly to a service panel. To convert to
460-volt, see sect. 6.3.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the, when used with 230V
power, be connected to a dedicated 20 amp circuit
with circuit breaker or time-delay fuse marked “D”.
When used with 460V power, connect the AB-14 to
a dedicated 10 amp circuit with circuit breaker or
time-delay fuse marked “D”.
NOTE: Local codes take precedence over
recommendations.
5.6 Material stop
Refer to Figure 5-1.
Screw lower rod (D) into threaded hole in base and
tighten hex nut (C) against base.
Install stop block with knobs (E) and upper rod as
shown.
6.1 GROUNDING INSTRUCTIONS
This machine 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.
If used with a plug:
