1.

Observe chip formation to be sure cutting is efficient.

 

Guide bearings not adjusted properly

1.

Adjust guide bearings according to instruction in this

 

 

manual.

 

Inadequate blade tension

1.

Check tightness of bearing seat bolt.

 

Blade tracking too far away from wheel

1.

Rough

Too much feed or speed

1.

Try one step lower speed and observe chip formation

cuts

 

for efficient cutting/feed rate.

 

Blade too coarse

1.

Use finer blade. Check with suppliers for recommen-

 

 

dations for the material you are cutting.

 

Incorrect blade for material

1.

Check with blade suppliers for recommendations for

 

 

exotic or unusual materials or specifications.

Blade

Cut is binding blade

1.

Be sure workpiece is flat on saw table.

twisting

 

2.

Decrease feed pressure.

 

Too much blade tension

1.

Reduce tension to just above point where blade slips.

 

Loose guide bearing eccentrics

1.

Check eccentric jam nuts for tightness.

 

Worn guide bearings

1.

Check guide bearings for wear. Replace if necessary.

 

Incorrect guide bearing adjustment

1.

Adjust guide bearings according to instructions in this

 

 

manual.

 

Loose guide bearing bracket

1.

Tighten bracket on saw arm.

 

Loose bearing seat attachment screw

1.

Tighten bearing seat attachment screw -- adjust blade

 

 

for vertical and parallel.

Unusual

Blade guides worn

1.

Replace.

Blade guide bearings not adjusted properly

1.

Check and adjust for proper clearance.

Blade running on wheel flange

1.

Adjust blade tracking using the paper cutting method.

Breaking

Teeth too coarse for work

1.

Use blade with finer pitch.

teeth

Too heavy feed

1.

Decrease feed rate -- observe chip formation to verify

 

 

efficient cutting.

 

Too slow speed

1.

Increase blade speed. Check technical literature or

 

 

blade or workpiece supplier for blade speed recommenda-

 

 

tions.

 

Vibrating work piece

1.

Be sure vise is tight.

 

 

2.

Support slender cross section or long workpieces with

 

 

appropriate out-feed supports.

 

 

3.

If stacking pieces in the vise, be sure all workpieces

 

 

are securely captured by the vise.

 

Tooth gullets loading

1.

Use coarser blade or one with a tooth geometry more

 

 

appropriate to the workpiece being cut.

 

Blade in contact with workpiece before motor

1.

Always allow motor to come fully up to speed before

 

is started

beginning cut.

Motor

Blade tension too high

1.

Decrease blade tension to just above slip point.

running too

Blade too coarse for work (pipes, especially)

1.

Use finer pitch blade.

hot

Blade is too fine for work (heavier, soft

1.

Use coarser blade.

 

material)

 

 

 

Worn transmission and worm gear

1.

Replace gears in transmission gearbox.

 

Gears need lubrication

1.

Check gearbox and add oil as required.

J-3410-2, J-3410 specifications

Jet Tools is renowned for its high-quality woodworking and metalworking equipment, and the J-3410 and J-3410-2 drill presses are prime examples of this commitment to excellence. These machines are engineered for precision, durability, and efficiency, appealing to both hobbyists and professional craftsmen.

The J-3410 features a robust 1 HP motor that provides ample power for a variety of drilling applications. This strength enables it to handle a wide range of materials, making it versatile enough for various projects. The machine operates at five different speeds, ranging from 600 to 3,100 RPM, allowing users to select the ideal speed for the specific material and drill bit size they are using. This versatility is crucial for achieving the desired results, whether it’s delicate woodwork or tougher metals.

One of the standout features of the J-3410 is its adjustable table, which can tilt up to 45 degrees, facilitating angled drilling. The table is constructed from heavy-duty cast iron, ensuring stability and reducing vibration, which is vital for precision work. Additionally, this model comes with a built-in laser guide that provides an accurate reference point for drilling, enhancing user efficiency and accuracy.

The J-3410-2 model builds upon the features of the J-3410, offering dual laser guides for even greater precision. These guides help users easily align the drill bit, ensuring that holes are drilled exactly where intended. The dual lasers also enhance visibility, especially in low-light environments. This model also includes a larger work table, allowing for drilling operations on bigger workpieces without compromising stability.

Both models are equipped with a heavy-duty, quick-adjust depth stop. This feature allows for consistency in repetitive drilling tasks, which is essential for users who need to achieve uniform results. They also feature an easy-to-use belt and pulley system for speed changes, ensuring that the transition between different speeds is effortless.

Safety is paramount in the design of the J-3410 and J-3410-2 press. A protective on/off switch prevents accidental start-ups, while the cast iron construction enhances overall stability and reduces the likelihood of accidents during operation.

The Jet Tools J-3410 and J-3410-2 combine power, precision, and safety, making them excellent choices for anyone in need of reliable drilling equipment. Whether for professional use or personal projects, these drill presses stand out in their class, showcasing Jet's commitment to quality and innovation.
