Chainsaw Carb Maintenance with an Ultrasonic Cleaner

Chainsaws are used in a wide range of applications including felling trees, limbing, stripping side shoots and buds from branches or shoots, general tree surgery and wood construction. This power tool can either be a gas-powered, electric-powered, pole type or top handle chainsaw. Capable of heavy duty work, a chainsaw operates using an engine which powers a cutting chain that works as a mechanical portable saw. To maintain the tool’s condition while extending utility and safety, owners should make sure their chainsaws are clean and maintained, inside and out.

A clean, well-tuned carburetor is a key factor in the performance of your chainsaw and nothing makes cleaning carburetors faster, safer and easier than an ultrasonic cleaner from iUltrasonic. Whether you operate a chainsaw service shop or do it yourself, you’ll be amazed at just how thorough an ultrasonic cleaner can be in removing varnish, grease, oil and other contaminants from your chainsaw.

How Ultrasonic Parts Cleaners Work on your Chainsaw Carburetor

Ultrasonic cleaners are used in a wide range of applications to remove virtually any soil or contamination by using the power of cavitation action. This is the term used to describe the implosion of billions of minute bubbles contacting carb parts being cleaned. The bubbles are created by generator-powered ultrasonic transducers bonded to an ultrasonic cleaning tank and typically operate at an ultrasonic frequency of 37 to 42 kHz (37,000 to 42,000 cycles per second).

When the bubbles implode contaminants are quickly and safely blasted away from wetted surfaces without damaging delicate carb parts. So tiny are the bubbles that they penetrate minute cracks, crevices and blind holes impossible to reach by hand scrubbing using conventional parts washers or aerosol sprays. The ultrasonic cleaner will complete the job in less than an hour, meanwhile freeing you up to attend to other tasks. And it will do it in an environmentally friendly manner because the ultrasonic carburetor cleaning formula is a biodegradable concentrate that minimizes disposal problems.

How to Select and Set Up your Chainsaw Ultrasonic Carb Cleaner

Ultrasonic carb cleaners come in a variety of sizes from bench top units to a floor-mounted industrial ultrasonic cleaning machine, so you can select any size you need. Our most popular 1½ gallon models for cleaning one carburetor at a time are the TOV150-6L and EH150EL. Select sonic cleaners equipped with heaters to improve the ultrasonic carburetor cleaning process.

Whatever the model and size ultrasonic carb cleaner you use there are steps to take before cleaning begins.

  1. Fill the ultrasonic carb cleaner tank to the fill line (or approximately 2/3 full) with ultrasonic cleaner solution diluted per manufacturer’s recommendations.
  2. Turn on the ultrasonic cleaner, set the heater to approximately 70°C, and operate the ultrasound for about 30 minutes to drive off cavitation inhibiting entrained air. Degassing is complete when bubbles stop coming to the surface and must be performed every time the tank is filled with fresh cleaning solution.

How to Remove, Clean and Reinstall your Chainsaw Carburetor

Step 1: Removing the Carburetor

To start off, unscrew the air filter cover that is held by just one screw. You will then have to remove the air filter by loosening and removing one screw as well. The carburetor has two screws located on both ends. Unscrew these to get your chainsaw carb cover off.

You should not just pull the carburetor out right away. First, pull the spark plug and the muffler out. Use needle nose pliers if you are having trouble using your fingers. Press the button to pull the choke off and unhook it from the throttle. Once this is done, simply pull your chainsaw carburetor off from the body.

You now hold in your hand, your chainsaw carburetor.

Congratulations! You have successfully removed your carb from your chainsaw! You may now proceed with the next step.

Step 2: Cleaning the Carburetor

Although you can clean your carburetor without any disassembly you will achieve the most thorough cleaning with partial disassembly to allow the solution into the float chamber. Remember that only surfaces that are wetted by the cleaning solution will be cleaned. Fine mesh baskets can be used to hold very small parts.

Set the thermostat to 70°C. While the solution is heating, place your carburetor parts in the basket taking care that they do not touch each other. Once the operating temperature is reached lower the basket into the cleaning solution and set the timer for 40 minutes. Cleaning time depends on the condition of the carburetor and may have to be adjusted.

At the end of the cycle remove the components from the sonicating water bath. If they are not clean replace them in the bath until the cleaning is complete. Then rinse them in fresh water to remove all traces of the cleaning solution and allow them to dry.

Safety note: DO NOT reach into an operating ultrasonic bath. Instead remove the basket if you want to inspect or rearrange the parts.

Step 3: Reinstalling the Carburetor

Return your chainsaw carb to the body. Press the button to insert the choke and hook it once again to the throttle. Use needle nose pliers or your fingers to return the spark plug and muffler to their original places. You will need to return your chainsaw carburetor cover that protects your carb. Screw this back on and make sure it stays in place. Return the air filter back to its original position by tightening the screw. Don’t forget to screw the air filter cover on as well.

Admire the piece of work you just put back together.

Voila! Turn the device on, and your chainsaw should be good to go

More Operating Tips

Oils that rise to the surface of the sonicator bath should be skimmed off and disposed of properly. When the solution becomes discolored or cleaning time takes longer it is time to replace it. Drain the tank and dispose of the spent solution according to local regulations. Take the time to remove sludge that settled to the bottom of the tank. Clean the tank using a cleaning process recommended by the manufacturer.
