JET Horizontal Band Saw: Model Identification, Setup, and Common Repairs
You own a JET horizontal band saw and you need help with model identification, setup, or repairs. JET horizontal band saws are popular in small and medium machine shops for cutting metal bar stock, pipe, and structural shapes. You need to know the model lineup, how to set up the saw, and how to fix common problems.
JET horizontal band saws are metal cutting saws where the blade runs horizontally and the saw head pivots down to cut through the workpiece. They are used for cutting metal bar stock, pipe, tubing, and structural shapes.
Model Identification

How to Identify Your Model
- Find the model number on the label on the saw frame.
- If the label is missing, measure the cut capacity and blade length.
- Check the motor label for horsepower and voltage.
- Look up the model number on the JET website or parts supplier.
Setup
Unboxing and Assembly
- Remove all packing material and protective coatings.
- Assemble the stand if the saw has a separate stand.
- Mount the saw on the stand and bolt it securely.
- Level the saw using the adjustable feet.
Installing the Blade
- Open the blade guard.
- Release blade tension using the tension knob.
- Remove the old blade from the wheels.
- Install the new blade on the wheels with teeth pointing toward the vise.
- Apply tension to the recommended setting.
- Check tracking by spinning the wheels by hand.
- Close the blade guard.
Adjusting the Vise
- Check that the vise is square to the blade.
- Adjust the vise angle if needed for angled cuts.
- Tighten the vise lock securely.
Setting the Speed
- Select the speed based on the material being cut.
- For step pulley models, change the belt position.
- For variable speed models, adjust the speed dial.
Setting the Feed Rate
- Adjust the hydraulic downfeed cylinder.
- Slow for thick or hard material.
- Fast for thin or soft material.
- The correct feed rate produces smooth, consistent cuts.
Common Repairs
Blade Breaks
Causes: Tension too high, blade guides too tight, blade worn, cutting radius too tight, poor blade quality. Solutions: Reduce tension, adjust guides, replace blade, use correct blade.
Poor Cut Quality
Causes: Dull blade, incorrect TPI, guides too loose, feed rate too fast, tension too low. Solutions: Replace blade, choose correct TPI, adjust guides, slow feed rate, increase tension.
Saw Vibrates
Causes: Drive belt worn, wheel bearings worn, blade unbalanced, saw not level. Solutions: Replace drive belt, replace wheel bearings, replace blade, level the saw.
Motor Hums but Does Not Start
Causes: Start capacitor failed, motor bearings seized, switch contacts burned. Solutions: Replace start capacitor (10 to 20 dollars), replace motor bearings or motor, replace switch.
Coolant Pump Does Not Work
Causes: Pump failed, coolant line clogged, coolant tank empty. Solutions: Replace pump (30 to 80 dollars), clear the line, refill the tank.
Vise Does Not Hold
Causes: Vise jaw worn, vise screw stripped, vise lock damaged. Solutions: Replace vise jaw, replace vise screw, replace vise lock.
Blade Selection
Blade Length
Check your saw’s manual for the correct blade length. Most JET 4x6 and 7x12 saws use a 64-1/2 inch blade.
TPI Selection
| TPI | Best For | Material Thickness |
|---|---|---|
| 6 to 8 TPI | Thick solid bar | 1 to 4 inches |
| 10 TPI | General metal cutting | 1/4 to 2 inches |
| 14 TPI | Medium thickness | 1/8 to 1 inch |
| 18 TPI | Thin material | Under 1/4 inch |
| 10/14 variable pitch | Mixed thicknesses | All |
Blade Material
Bi-metal M42: The standard. Handles mild steel, stainless, aluminum. Cost: 15 to 30 dollars. Bi-metal M51: Harder edge for tough materials. Cost: 20 to 40 dollars. Carbide-tipped: Longest life for production. Cost: 50 to 150 dollars.
Maintenance Schedule
Daily: Clean chips from the vise and blade guard. Check blade for wear. Check coolant level. Weekly: Clean the chip tray. Lubricate the vise screw. Check blade tracking. Monthly: Check drive belt tension and condition. Check all bolts for tightness. Clean the coolant tank. Annually: Replace coolant. Check wheel bearings. Inspect electrical cord and switch.
FAQ
How do I identify my JET horizontal band saw model?
Find the model number on the label on the saw frame. Common models include 414557 (4x6), 414560 (7x12), and HVBS-7MW. If the label is missing, measure the cut capacity and blade length.
