    What to do if my Wen Saw motor does not start?
    • J
      joykleinJul 29, 2025
      If the motor of your Wen Saw doesn't start, first, make sure the unit is properly plugged in. If it is, there may be a defective power switch, power cord, start capacitor, or even a defective motor. For assistance with these issues, it's best to contact customer service.

    Why is my Wen Saw cut squaring inaccurate?
    • C
      Christopher MooreAug 2, 2025
      Inaccurate cut squaring with your Wen Saw can occur for several reasons. It may be due to excessive cutting pressure from an incorrect feed rate, or an incorrect choice of blade tooth count. Also, check the adjustment of the sliding blade guides to ensure they are as close to the workpiece as possible. Incorrect cutting speeds, a workpiece not securely clamped or improperly positioned, or poor blade tension can also cause this issue. Contact customer service if the blade is warped.

      Alex RobertsonAug 8, 2025
      If your Wen Saw is stalling or feels underpowered, it could be due to a few reasons. You might be using the wrong blade for the workpiece material, so try using a different blade that's more suited to the material type. Also, inspect the V-belt for wear or looseness and replace it if needed. Finally, check if the pulley is loose; if so, realign the pulleys and tighten the set screws.

    Why does my Wen BA4664 vibrate or operate noisily?
    • K
      Kelly BrownAug 13, 2025
      If your Wen Saw is vibrating or operating noisily, several factors could be the cause. First, verify that the belt cover was installed properly, as the V-belt might be hitting it. Also, inspect the V-belt for wear or looseness and replace it if necessary. Check if the pulley is loose; if it is, realign the pulleys and tighten the set screws. Contact customer service if you suspect worn bearings.

    What to do if teeth are ripping from the blade of my Wen BA4664?
    • F
      flowersjoanneAug 18, 2025
      If teeth are ripping from the blade of your Wen Saw, it could be because the feed rate is too high, the blade speed is too slow, or the blade is too coarse for the workpiece. Try decreasing the feed rate, adjusting the blade speed, or replacing the blade. Also, ensure the workpiece is securely clamped, using a jig if necessary. If the blade teeth gullets are loading up with chips, switch to a coarser-tooth blade.

    Why does the blade on my Wen Saw tend to protrude from the guide bearings?
    • M
      Mark TownsendAug 23, 2025
      If the blade on your Wen Saw tends to protrude from the guide bearings, it could be due to excessive blade tension, so check the blade tension. Another possible cause is incorrect tracking adjustment, so adjust the blade tracking. Blade slippage on the guide bearings might occur if cutting oil has been used; it is not recommended to use lubricant or coolant with this bandsaw.

Overview

The WEN BA4664 is a 4-inch by 6-inch metal bandsaw designed for cutting flat and round pieces of metal. This tool is engineered for dependability, ease of operation, and operator safety, providing years of rugged, trouble-free performance when properly cared for and used for its intended purpose.

Function Description:

The WEN BA4664 metal bandsaw is primarily used for precision cutting of various metal workpieces. It can operate in both horizontal and vertical cutting positions, offering versatility for different project requirements. In horizontal cutting, it utilizes a work stop for quickly and accurately cutting multiple pieces of stock to the same length. For vertical cutting, it can be assembled with a vertical table assembly to support workpieces that cannot be properly stabilized with a vise. The saw features adjustable blade guides to minimize side-to-side blade movement and a vise for securing workpieces at various angles (0° to 45°). The feed rate is controlled by a spring and handle mechanism, allowing users to adjust the tension to decrease or increase the feed rate. Blade speed is also adjustable, offering three different settings to accommodate various metal types and cutting needs. A head locking pin is included to safely secure the saw head in the down position when not in use or during transport, preventing unexpected movement.

Important Technical Specifications:

Usage Features:

The WEN BA4664 is designed with several features to enhance usability and safety.

  • Adjustable Vise: The vise allows for angle adjustments from 0° to 45°, enabling miter cuts. Hex bolts on both the large and small jaws can be loosened to set the desired angle and then retightened to secure the workpiece. The vise handle is used to open or close the jaws and tighten against the workpiece.
  • Adjustable Blade Guide: A knob allows the blade guide to be slid as close to the workpiece as possible, minimizing blade movement and improving cut accuracy.
  • Adjustable Feed Rate: The feed rate is controlled by a spring and handle. Twisting the handle clockwise increases spring tension, decreasing the feed rate, while twisting counterclockwise removes tension, increasing the feed rate. This allows for optimization based on material and desired cut quality.
  • Adjustable Blade Speed: The bandsaw offers three blade speeds (80, 120, 180 FPM) which can be adjusted by changing the V-belt placement on the motor and worm gear pulleys. This flexibility allows users to select the appropriate speed for different metal types, ensuring efficient and clean cuts.
  • Head Lock Pin: A head locking pin is provided to secure the saw head in the down position, preventing accidental spring-up and ensuring safety during transport or when the tool is not in use.
  • Transportation Handle and Wheels: For ease of movement, the assembled saw can be rolled using the transportation handle and wheels, avoiding the need to carry it by its guards or accessories.
  • Work Stop: The work stop assembly allows for consistent cutting of multiple pieces to the same length in horizontal mode.

Maintenance Features:

Regular maintenance is crucial for the longevity and safe operation of the WEN BA4664.

  • Routine Inspection: Before each use, users should inspect for loose hardware, damaged or dull blades, misalignment or binding of moving parts, damaged cord/electrical wiring, cracked or broken parts, and any other condition affecting safe operation.
  • Cleaning & Storage: Ventilation openings should be kept free from dust and debris to prevent motor overheating. A brush and shop vacuum are recommended for removing chips and debris. The tool surfaces should be wiped clean with a dry cloth. When storing for extended periods, the blade should be removed or its tension relieved to prevent warping and prolong its life. The tool should be stored in a clean, dry place between 41°F and 86°F.
  • Lubrication: The bandsaw's bearings are permanently sealed and do not require additional lubrication.
  • Oil Replacement: The gear oil (L-CKE gear oil, ISO VG 220) should be replaced approximately once a year under normal usage, or more often for professional/industrial use. The gear box can be opened by removing six screws to drain and replace the oil.
  • Changing the Saw Blade: The manual provides detailed instructions for safely changing the saw blade, including locking the saw in the vertical position, removing guards, loosening tension, and installing the new blade with correct orientation. Protective gloves are recommended when handling blades.
  • Adjusting Blade Tracking: While factory-set, blade tracking can be adjusted if problems occur, especially after replacing a blade. This involves loosening shaft locking bolts and carefully turning the shaft tracking bolt while observing the blade's movement on the wheel. This adjustment should be performed by a qualified person with the back cover open, wearing appropriate safety gear.
  • Blade Alignment: Users should ensure the blade is properly aligned on both wheels and adjust blade tension so it sits centered and does not move during operation. The blade guard can also be adjusted to straighten the blade and prevent it from slipping off the wheels.

The manual emphasizes the importance of reading and understanding all safety warnings and instructions before operating the tool to prevent electric shock, fire, and serious injury. It also provides troubleshooting guidance for common issues such as the motor not starting, machine stalling, noisy operation, inaccurate cuts, and blade protrusion.
