1.0 IMPORTANT SAFETY

INSTRUCTIONS

READ ALL INSTRUCTIONS BEFORE USING THIS MACHINE.

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. Replace warning labels if they become obscured or removed.

3. This pneumatic Hydraulic shear 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 shear, do not use until proper training and knowledge have been obtained.

4. Do not use this machine 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.

5. Always wear ANSI approved safety glasses/face shields while using this shear.

Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

6. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Wear protective hair covering to contain long hair. Non-slip footwear or anti-skid floor strips are recommended.

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

8. Do not exceed the rated capacity of this shear; use hand tools for small or narrow parts. Do not attempt to shear hardened materials.

9. Sheet metal stock has sharp edges. To prevent cuts, use leather work gloves when handling.

10. Keep hands and fingers clear of the area in front and rear of the shear.

11. Do not place your hands between material being sheared and the shear table.

12. 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.

13. 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.

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

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

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. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury.

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

20. 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.

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

22. Maintain tools with care. Keep tools sharp and clean for the best and safest performance. Follow instructions for lubricating and changing accessories.

23. Do not stand on the machine. Serious injury could occur if the machine tips over.

24. Unplug or lock out power to the machine when not in use.

7.2 Unpacking

Open shipping container and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Shear is assembled and running properly.

Compare the contents of your container with the following list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor. Read the instruction manual thoroughly for assembly, maintenance and safety instructions.



1. Remove the crating material from around the machine.

2. Clean the protectant from all exposed metal surfaces with a mild solvent or kerosene, and a soft rag. Do not use lacquer thinner, paint thinner, or gasoline, as these may damage painted surfaces.

3. Coat all machined surfaces with a light coat of oil to inhibit rust.

4. Remove the bolts holding the machine to the skid.

5. Place straps below the table (you may have to remove front cover), and use properly rated lifting equipment to move the machine to a level foundation. Machine location must allow access to all sides. Use shims at floor if needed.

Assembly Note: Prior to shipment, the hydraulic shear is adjusted at the factory for proper alignments and operation. If the machine does not operate properly or the stand does not sit squarely on the floor, proceed to Adjustments.

6. When the machine sits evenly, secure it to the floor using proper fasteners. Refer to Figure 2.

7.3 Stop assemblies

Refer to Figure 1.
