Introduction This manual is provided by JET, covering the safe operation and maintenance procedures for a JET Model J-9180 zip-miter bandsaw. This manual contains instructions on installation, safety precautions, general operating procedures, maintenance instructions and parts breakdown.

Saw Head Shipping Contents The saw head (Figure 1) consists of a drive motor, gearbox, blade wheels, blade guides and supports, control panel, blade tension mechanism, wire brush, and the saw blade. Contents of the Carton 1 1 1 1 1 1 1 1 Band Saw (not shown) Front Stand Panel (A) Rear Stand Panel (B) Left Stand Panel (C) Right Stand Panel (D) Bottom Plate (E) Operating Instructions/Parts List Warranty Card The drive wheel is installed on the output shaft of the gearbox.
Assembly Referring to Figure 3: Stand Assembly 1. The saw (A) and stand top (B) come as an assembled unit. Use a hoist to lift and place the saw onto the stand (C). Tools required for assembly: Note that the front of the saw faces the same direction as the indented panel of the stand. Two 1/2-inch wrenches (Note: A ratchet wrench may speed assembly time.) Referring to Figure 2: 2. Adjust the stand top (B) and stand (C) so the corner mounting holes (D) are aligned. 1.
Controls and Indicators Control Panel The operating controls for the bandsaw are located on the control panel (Figure 4) and consist of the following controls and indicators: Emergency Stop Switch – by depressing this switch the user can quickly stop the machine when it is in operation; to restart, turn clockwise slightly to release then press Start switch Feed Rate Control – used in conjunction with the Feed Rate Start/Stop Control (see below); this knob is used to set the downward head speed that is appli
Blade Selection Operations The cut-off saw is delivered with a saw blade that is adequate for a variety of cut-off jobs on a variety of common materials. A general-purpose blade is provided as standard equipment with the machine. After-market blades can be acquired for specific cutting jobs. Hydraulic Feed Control A coarse blade could be used for a solid steel bar, but a finer tooth blade would be used on a thin-wall steel tube.
Setting the Work Stop Referring to Figure 7: The work stop is an accessory that is included with the JET J-9180 Bandsaw. It is used to set up the saw for making multiple cuts of the same length. Do not allow the blade to rest on the workpiece when the saw is not cutting. Installation 1. Screw the threaded end of the distance set rod (A) into the hole at the front of the base (B) as shown. 2. Secure by tightening the lock nut (C) with a 22mm hex wrench. Adjustment 3.
Miter Cuts Referring to Figure 9, the J-9180 bandsaw is capable of making angle cuts from 0–60º. The vise remains stationary while the saw head is adjusted as follows: 1. Place the saw head (F) in the raised position so the blade doesn't catch in the table slots. 2. Set the lock handle (A) to the unlock position as indicated by the arrows. 3. Using handles (B and C), rotate the saw head (F) to any desired angle within a range of 0º (square cut) to 60º, setting it to the scale (D) on the base. 4.
Guide Bearing Adjustment Referring to Figure 12: Guide bearings are located on either side of the saw blade and provide stability for the blade when the saw is in operation. These bearings rotate on an eccentric shaft so the distance from the blade can be adjusted for optimal performance. Guide bearings are initially adjusted at the factory and should rarely require adjustment. It is always better to try a new blade when cutting performance is poor.
Blade Tension Blade tension is covered in the Changing Blades section on page 15. Limit Switch Adjustment Refer to Figure 14. The J-9180 bandsaw should shut off automatically when a cut is completed. If not, the limit switch (A) located below the control panel (Figure 1) probably needs to be adjusted as follows: Disconnect the cut-off saw from its electrical power source. 1. Place the saw in the lowered position to represent the completion of a cutting operation.
Maintenance Figure 15 Changing Blades 4. Pull the blade (E) off the drive wheel (F) and idler wheel (G) and out of the blade guides (H1, H2). Store the removed blade carefully before proceeding. Refer to Figure 15 except where specified otherwise. Use leather gloves when changing the saw blade to protect your hands from cuts and scratches. Use protective eye wear that meets ANSI Specification Z87.1 Installing New Blade 5.
Cleaning Coolant Clean off any preservative on machine surfaces. Change coolant with a frequency appropriate to the type of coolant being used. Oil based coolants can sour. Refer to the coolant supplier’s instructions for change frequency. After cleaning: 1. Coat machined surfaces of the cutoff saw with a medium consistency machine oil. Reapply the oil coating at least every six months. The general-purpose coolant is a mixture of water-soluble oil or synthetic based coolant and water.
Troubleshooting Fault Probable Cause Suggested remedy 1. Clamp work securely. 2. Check Machinist’s Handbook for speed/feed appropriate for the material being cut. 3. Check Machinist’s Handbook for Teeth too coarse for material. recommended blade type. 4. Adjust blade tension to the point Incorrect blade tension. where the blade just does not slip on the wheel.
