Milwaukee 6130-33 Cut-Off Tool Produces a Subtle Rustling Sound During Operation

Is your Milwaukee 6130-33 Cut-Off tool experiencing malfunctions, displayed by rustling noises and a noticeable decline in performance? Use this troubleshooting guide to help diagnose why.

When using the cut-off wheel, it is important to ensure that the disc is securely fastened, along with the other safety components, including the flange nut and safety guard.

• Once you have confirmed that the wheel is securely fastened, the device should operate at its normal levels.
• If the disc exhibits any chips, dents, or signs of wear, it is likely indicative that the wheel requires a replacement disc.
• If the disc still exhibits signs of disfunction after replacement, it is likely indicative of issues with the motor or gears.

If, after cleaning and checking for loose components, the wheel continues to stay loose, remove and replace the cut-off wheel as shown in our Cut-Off Wheel Replacement Guide.

The Gears is located just below the Cut-Off wheel and can be worn over time through usage. Thus, you can access the gears by removing the guards/clamps, now by locating the four screws you can access the gears.

• If you notice any grinding sounds or signs of wear on the gears, it is likely that the blades need to be replaced. Contact the company or search the supplier's website to obtain a new set of gears.

Check for any filings or dust build up within the gears, removal by a brush is effective in cleaning the gears.

If, after cleaning the gears, the gear continues to malfunction, remove and replace the gears as shown in our Gear Replacement Guide.

The loss of motor sounds or a grinding motor sound is an indication to inspect the brushes.

• Once the bottom casing is removed, the next step it to push the brushes ensuring the springs are still working and, not worn down as this could cause problems with the rotor as well.

Additionally, checking the alignment of the sheet metal surrounding the brushes can resolve the problem, as improper snagging can cause a disfunction in the brushes.

If, after inspecting the brushes, the brush remains stuck, remove and replace the safety brush springs using our Safety Brush Springs Replacement Guide.

The Fan Casing serves as a heat regulator to the gears and motors. Fan Casing failure can be identified as overheating or abnormal air sounds.

• Following from the Brush Springs step, continue with the bottom casing and springs removed.
• Remove the four screws of the metal head from the rim of the metal head.
• Remove the gear cover along with the rotor, then move to the four screws securing the Fan Casing.

If, after inspecting the fan casing, the casing continues to overheat, remove and replace the fan casing using our Fan Casing Replacement Guide.

Damage to wiring will result a power loss to the device.

• Located next to the brushes will be the wiring to the device. Here check for wire damaging or disconnection that may indicate any wiring problems.
• Also, ensure the wires aligned in the correct positions as displayed in the device manual.

If, after inspecting the wiring, the device power continues to fail, remove and replace the wiring system using our Wiring System Replacement Guide.
