1. Read and understand the entire owner’s manual before attempting assembly or operation.
2. Read and understa nd the warnings pos ted on the m achine and i n this m anua l. F ailure t o com pl y with
all of these warnings m ay cause serious injury. Replace warnin g labels if they become obscur ed or
removed.
3. This pneumatic Hydraulic shear is designed and intended for use by properly trained and experienced
personnel only. If you ar e not familiar with the pr oper and safe oper ation of a shear, do n ot use until
proper training and knowledge have been obtained.
4. Do not use this mac hine f or other than its intended use . If used for other purposes, JET dis c laims any
real or implied warranty and holds itself harmless from any injury that may result from that use.
5. Always wear ANSI a pprove d saf ety gl asses /fac e shields while us ing t his sh ear. Ev eryday eyeglas ses
only have impact resistant lenses; they are not safety glasses.
6. Do not wear loose cloth ing, gloves, neck ties, rings, bracelets, or other jewelr y which may get caught
in moving parts. Wear protective hair co vering to contain long ha ir . No n-slip footwear or anti-skid floor
strips are recommended.
7. Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contains chemicals known to caus e cancer , birt h defects or other r eprod uctive har m . Some ex amples
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 well-ve nti lat ed ar ea a nd work w ith a ppro v ed s af et y equ ipment,
such as face or dust masks that are specifically designed to filter out microscopic particles.
8. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.
9. Do not exceed the rated capacity of this shear; use hand tools for small or narrow parts. Do not
attempt to shear hardened materials.
10. Sheet metal stock has sharp edges. To prevent cuts, use leather work gloves when handling.
11. Keep hands and fingers clear of the area in front and rear of the shear.
12. Do not place your hands between material being sheared and the shear table.
13. 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.
14. 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 alignm ent of moving parts, binding of moving parts, break age of parts, mounting a nd any
other conditions that may affect its operation. A guard or other part that is damaged should be
properly repaired or replaced.
15. Provide for adequate space surrounding work area and non-glare, overhead lighting.
16. Keep the floor around the machine clean and free of scrap material, oil and grease.
17. Keep visitors a safe distance from the work area. Keep children away.
18. Make your workshop child proof with padlocks, master switches or by removing starter keys.
19. Give your work undivided attent ion. Looking around , carrying o n a conversati on and “hors e-play” are
careless acts that can result in serious injury.
20. Maintain a balanced stance at all tim es so that you do not f all or lean against m oving parts. Do not
overreach or use excessive force to perform any machine operation.
21. Use the right tool at th e cor rec t spee d and feed rate. Do n ot f orce a too l or at tach m ent to d o a j ob f or
which it was not designed. The right tool will do the job better and more safely.
22. Use recommended accessories; improper accessories may be hazardous.

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.
7.4.1 Grounding instructions
This machine m ust be grounded . In the event of
a malfunction or bre akdown, gro unding prov ides
a path of least res istance for electric current to
reduce the risk of electric shock.
Improper connection of the equipmentgrounding conductor can result in a risk of
electric shock. The conductor with insulation
having an outer surface that is green with or
without yellow stripes, is the equipmentgrounding conductor. I f repair or r eplacem ent of
the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is pr operly grounded . Repair or
replace a damaged or worn cord immediately.
7.4.2 Extension cords
The use of an extension cord is not
recommended. Try to place shop equipment
within reach of th e po w er source. If an ex tension
cord becomes necessary, make sure the cord
rating is suitable for the amperage listed on the
machine’s motor plate. An undersized cord will
cause a drop in line voltag e resulting in loss of
power and overheating.
*based on limiting the line voltage drop to 5V at 150% of the
rated amperes.
NR: Not Recommended.
Table 1
8.0 Adjustments
8.1 Adjustment for the shearing edge
gap
The relationship between plate thickness and
cutting edge data is shown in Figure 3.
Figure 3
To adjust gap (Figure 4):
1. Loosen bolts (1,2,3).
2. Tighten bolt (4) to increas e gap. Loos en bolt
(4) and tighten bolt (3) to decrease gap.
NOTE: Adjust equally at both ends of
machine.
3. Check gap with feeler gauge.
4. When gap value and shear plate thickness
correspond, tighten nut (2) and bolts (1).
Use the chart in Figure 17 as a gener al guide i n
choosing the correct size cord. If in doubt, use
the next heavier gaug e. The smaller the gauge
number, the heavier the cord.
Figure 4

8.2 Adjustment for back gauge
9.0 Maintenance
Position rear stop to “ 0” on the scales, and v erify
that stop plate is par allel to shear. If not, lo osen
screw (1) and rotate nut (2) until aligned.
Retighten screw (1).
To adjust rear stop f or operations, loosen ha ndle
(4) and rotate handwheel (5) until desired
measurement is reached. Lock handle (4).
Figur e 5
Use care when working with
or around the knives.
The 2-way upper knife can be removed and
flipped 180°, for a new e dge before ha ving to be
sharpened.
Wipe the blades lightly with oil.
Lubricate all pivot points on the machine daily.
10.0 Troubleshooting the HS-1452
Trouble Probable Cause Remedy
Incorrect gap between blades. Increase gap for thicker gauge metals.
Blades will not cut
material.
Unsatisfactory cuts.
Cuts not square.
Material exceeds machine cap acity . Stay within capacity.
Blades are dull. Replace or sharpen blades.
Blades dull. Replace or sharpen blades.
Incorrect gap between blades. Correct gap.
Loose gibs. Remove backlash from gibs.
Inadequate hold-down pressure. Adjust pressure of hold-down.
Blade gap unequal. Adjust gap equally across length of blade.
Uneven guide contact. Place work against guide consistently.
