Troubleshooting

Problem

Probable cause

 

Potential solutions

Excessive

Material loose in the vise

1.

Use more pressure to tighten vise.

blade

 

2.

Check stationary jaw pivot and lock bolts for tightness.

breakage

 

3.

Check quick release handle nut for excessive tightness

 

 

-- nut should be just tight enough to keep adjustable jaw

 

 

from tilting when tightening.

 

 

4.

If you are stacking multiple pieces in the vise, be sure

 

 

all of the pieces are captured by the vise pressure.

 

Incorrect feed or speed

1.

Check technical literature for recommended feeds and

 

 

speeds for the material and blade you are using.

 

 

2.

Check chip formation to adjust speed and feed to

 

 

correct rate when sawing.

 

Incorrect blade tension

1.

Adjust blade tension to where it just does not slip on

 

 

the wheel.

 

Teeth in contact with work before saw is

1.

Be sure the saw motor has come fully up to speed

 

started

before beginning a cut and be sure the blade is not resting

 

 

on the workpiece before the motor has come up to full

 

 

speed.

 

Blade rubs on wheel flange

1.

Use paper cutting method of adjusting blade tracking.

 

 

See Blade Tracking Adjustment.

 

 

2.

Check drive and idler wheels for looseness in mount-

 

 

ing parts or worn/damaged bearings.

 

Misaligned blade guides

1.

Adjust blade guides.

 

Blade too thick for wheel diameter

1.

Use a thinner blade. Check with your blade supplier

 

 

for recommendations on blade thickness for a specific

 

 

wheel diameter.

 

Cracking at weld

1.

Replace blade.

Premature

Teeth too coarse

1.

Use finer tooth blade.

blade

Too much blade speed

1.

Try next lower speed or check technical literature for

dulling

 

specific recommendations regarding speeds for specific

 

 

blade and material being cut.

 

 

2.

Check with materials supplier for recommendations on

 

 

the workpiece material supplied.

 

 

3.

If using coolant, check with supplier regarding correct

 

 

coolant for the job.

 

Inadequate feed pressure

1.

Increase pressure while observing chip formation to be

 

 

sure you are cutting efficiently.

 

Hard spot or scale on material

1.

Reduce speed of blade.

 

 

2.

Increase feed pressure in scale or hard spots .

 

Work hardening of material (especially

1.

Work hardening materials such as stainless require a

 

stainless steel)

heavy, continuous cut. Be sure you are using a sharp

 

 

blade, then, if necessary, release some counterbalance

 

 

spring pressure by loosening the tension nut if work

 

 

hardening of the material is a problem.

 

Blade installed backwards

1.

Reinstall blade so teeth point toward right end of saw.

 

Incorrect coolant or no coolant

1.

Check with materials supplier and/or blade supplier for

 

 

coolant recommendations.

 

 

2.

Check with coolant supplier for specific recommenda-

 

 

tions on the blade and material you are using.

 

Insufficient blade tension

1.

Increase tension so blade is above the slipping point.

Crooked

Work not square

1.

Adjust the stationary vise jaw so it is square to the

cuts

 

blade.

 

 

2.

Clamp work tightly in the vise.

 

 

3.

Check blade for vertical and adjust, if necessary.

 

 

4.

Perform test cuts according to instructions on page

 

 

until cuts are satisfactorily square.

 

 

5.

Move guide bearings as close as possible to work

 

 

while still completing the cut.

 

 

6.

Check guide bearings, seats and brackets for possible

 

 

looseness or wear.

Jet Tools J-3410-2 operating instructions Troubleshooting, Problem Probable cause Potential solutions

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.
