RULES FOR SAFE OPERATION
To help ensure safe operation, please take a moment to learn the machine’s applications and limitations,
as well as potential hazards. General
®
International disclaims any real or implied warranty and holds itself
harmless for any injury that may result from the improper use of it’s equipment.
1. Do not operate the bandsaw when tired, distracted
or under the effects of drugs, alcohol or any medI-
cation that impairs reflexes or alertness.
2. The work area should be well lit, clean and free
of debris.
3. Keep children and visitors at a safe distance when
the bandsaw is in operation; do not permit them to
operate the bandsaw.
4. Childproof and tamper proof your shop and all ma-
chinery with locks, master electrical switches and
switch keys, to prevent unauthorized or unsupervised
use.
5. STAY ALERT! Give your work your undivided attention.
Even a momentary distraction can lead to serious
injury.
6. Fine particulate dust is a carcinogen that can be
hazardous to health. Work in a well-ventilated area.
Wear face, eye, ear, respiratory and body protec-
tion devices.
7. Do not wear loose clothing, gloves, bracelets,
necklaces or other jewelry while the bandsaw is in
operation.
8. Be sure that adjusting wrenches, tools, drinks and
other clutter are removed from the machine and/or
the table surface before operating.
9. Keep hands well away from the blade and all
moving parts. Use a brush, not hands, to clear away
chips and dust.
10. Adjust and position the blade guides before starting
to cut.
11. Adjust blade tension and tracking before starting to
cut.
12. Blade teeth must point down toward the table.
13. Be sure that the blade has gained full operating
speed before starting to cut.
14. Always use a clean, properly sharpened blade.
Dirty or dull blades are unsafe and can lead to
accidents.
15. Use suitable workpiece support if the workpiece
does not have a flat surface.
16. Make sure the workpiece is securely held in place
in the vise.
17. Do not work on long stock without adequate sup-
port on the out feed end of the table.
18. Do not push or force stock into the blade. The band-
saw will perform better and more safely when work-
ing at the rate for which it was designed.
19. Avoid working from awkward or off balance posi-
tions. Do not overreach and keep both feet on floor.
20. Keep guards in place and in working order. If a
guard must be removed for maintenance or clean-
ing be sure it is properly re-attached before using
the saw again.
21. Never leave the machine unattended while it is run--
ning or with the power on.
22. Use of parts and accessories NOT recommended
by General
®
International may result in equipment
malfunction or risk of injury.
23. Never stand on machinery. Serious injury could re-
sult if the tool is tipped over or if the cutting tool is
unintentionally contacted.
24. Always disconnect the saw from the power
source before servicing or changing accessories
such as blades, or before performing any mainte-
nance or cleaning, or if the machine will be left
unattended.
25. Make sure that the switch is in the “OFF” position
before plugging in the power cord.
26. Make sure the machine is properly grounded. If
equipped with a 3-prong plug it should be used with
a three-pole receptacle. Never remove the third
prong.
27. Do not use this bandsaw for other than its intended
use. If used for other purposes ,General® International
disclaims any real or implied warranty and holds it
self harmless for any injury, which may result from
that use.

Questions and Answers

    Why is the motor on my General 90-725 Saw overheating?
    • O
      Olivia ScottAug 6, 2025
      Motor overheating in your General Saw can stem from several factors. If the blade tension is too high, reduce it. Similarly, if the motor belt tension is too high, reduce that as well. Ensure you are using the correct blade for the job; a blade that is too coarse requires you to use a finer blade, while a blade that is too thin requires you to use a thicker blade. Check the oil level of the gears, because gears needing lubrication can cause the motor to overheat. If the gears are improperly aligned, adjust them so that the worm is in the center of the gear. Lastly, if the blade is binding, reduce the feed pressure.

    Why is my General 90-725 blade dulling prematurely?
    • W
      warrencoleAug 10, 2025
      Premature blade dulling in your General Saw can occur due to several reasons. If the blade teeth are too coarse, switch to a finer tooth blade. If the speed is too high, reduce it. Excessive feed pressure can also cause dulling, so reduce feed pressure with the cylinder. For materials with hard spots or scale, reduce the speed and increase feed pressure. If the material is hardening, increase feed pressure by tightening the cylinder lock knob. Insufficient blade tension can also lead to dulling, so ensure you tension the blade. If the blade twists or slides, replace the blade and adjust its tension.

    How to fix a bad (crooked) cut on my General Saw?
    • R
      Robert MillerAug 15, 2025
      A crooked cut with your General Saw can arise from several issues. Start by reducing the feed pressure if it's too high. Ensure the guide bearings are properly adjusted. Insufficient blade tension is another common cause, so tension the blade. Replace the blade if it is dull. Adjust the speed if it is incorrect for the material. Check the blade guide spacing and adjust it if the blade guide is too far from the blade. If the blade guide loosens, re-tighten the lock knobs. Finally, adjust blade tracking if the blade tracks too far from the wheel shoulder.

    What to do if my General 90-725 Saw is producing a bad (rough) cut?
    • Z
      Zachary RobertsAug 19, 2025
      A rough cut on your General Saw can be caused by several factors. If the blade or feed speed is too high, reduce either. If the blade is too thick, replace it with a thinner blade. Insufficient blade tension can also lead to a rough cut, so ensure you tension the blade. Blade tension being too high can also cause the same problem, so reduce blade tension. If the blade is binding, reduce the feed pressure.

    What causes broken teeth on my General Saw blade?
    • S
      scottscottAug 22, 2025
      Broken teeth on your General Saw blade can occur for several reasons. If the blade teeth are too coarse, use a finer tooth blade. If the pressure is too high or the speed is too slow, reduce the pressure and increase the speed. Vibrating workpiece may be the reason, so clamp the workpiece properly. Excessive chips can also cause broken teeth; use a thicker tooth blade or brush regularly to remove chips.

    Why is the blade twisting on my General 90-725 Saw?
    • E
      Erica McgrathAug 27, 2025
      If the blade is twisting on your General Saw, it could be due to bending blade (reduce feed pressure) or blade tension being too high (reduce blade tension).

    Why is my General 90-725 experiencing excessive blade breakage?
    • W
      William ArnoldOct 31, 2025
      Excessive blade breakage in your General Saw can occur for several reasons. First, ensure the workpiece is securely tightened in the vise. If not, tighten the vise. Other causes include incorrect feed speed (adjust the feed speed), using a blade with teeth spacing that's too large (replace the blade with one that has correct teeth spacing), or using a blade that is too thick (use a thinner blade). Also, ensure correct blade tension by tensioning the blade, and if the material is too coarse, use a blade of slow speed and small teeth spacing. Additional causes can be the blade rubbing on the wheel flange (adjust wheel alignment), a misaligned guide bearing (adjust guide bearing), the blade cracking at the weld (weld again), or the teeth contacting the workpiece before the saw is turned on (p...
