How to Clean a lawnmower Paper Air Filter

The main reason for using paper air filters is to save the lawnmower’s engine and carburetor from any dirt that may have come in during the time you have your lawnmower engine running. In this regard, a properly working air filter in a lawnmower serves as the first defense line. The dirt and grass clippings could enter the engine if the air filter is worn out and cause excessive damage to the engine parts and drastically hamper the engine’s efficiency.

Cleaning or repairing your lawnmower’s air filter is considered an integral part of general maintenance. Following the steps protects the machine from risks and increases the machine’s performance by extending its lifespan. In the case of pre-cleaner foam, it needs to be washed every 25 working hours. On the other hand, replacement is needed after at least 300 hours of operation in the paper air filter case. Specifically, in dusty environments, an air filter’s replacement is important because it can get stuck. There is no room left for the air to reach the engine when an air filter gets clogged. As oxygen, an important element for initiating the engine’s combustion fails to reach the engine, there will be no engine combustion.

There are various kinds and types of air filters out there, depending upon the machine you are using. The most efficient is the dual-element air filter due to multiple layers: the foam elements and air-pleated. The other type of air filter is foam filters that consist of foam. In this article, we will briefly discuss how to clean a paper air filter in our lawnmower.

Clean your lawnmower’s paper air filter in 8 easy steps.

Step 1: Check the Type of Paper Air Filter you use in your Lawnmower

Proper research and knowledge regarding your machine serve to be the first and foremost task once we are set to clean your device’s paper air filter. A user manual consists of all the details one needs to know about his machine and eventually decipher the air filter your device uses. Moreover, referring to online resources could also help an individual do searches tailored to his machine’s model and make that could eventually help look for the right replacements it needs.

The method to clean the air filter vary from machine to machine. This is because each machine either uses a single paper air filter or a dual air filter that is a combination of paper and foam air filter. Thus, depending upon the type underhand, the cleaning process might vary.

Step 2: Turn off the lawnmower

Once you have discovered the model and make of your machine via research, you are now aware of its structure that not only helps you to identify its parts to pinpoint where an air filter is present but also helps you necessary information about its components that would, in turn, help you to gather supplies for a replacement if necessary.

Turning off or disconnecting the lawnmower is the next step, which serves to be more of a safety precaution. This step is necessary as many parts in a lawnmower might be operational even though the machine is not started.

Step 3: Remove / Disconnect the spark plugs

Like the previous step, this step also serves to be a precautionary measure before one decides to clean lawnmower engine parts. It is an extra precaution and security against engine back start. Spark plugs are generally located on the engine’s front end and are an integral part of the machine. Once the plugs have been located, you could either disconnect the wires or remove them with appropriate tools.

Step 4: Locate the air filter

Once all the precautionary measures have been taken, and the machine is completely turned off and idle, the next step is to locate the air filters. Generally, the air filters are placed in an encapsulation made of either plastic or metal. This casing is generally present close to the engine.

Step 5: Vaccum the Paper air filter

Once the paper air filter has been identified, unscrew the plastic or metal casing and remove the paper air filter from it. Once removed, tap the air filter against some solid surface like a wall until a comparable amount of dust has been shaken off.

Now take out a vacuum cleaner and attach a hose of the appropriate site to it. Use this vacuum to clean out all the contaminations. Take at least one minute to clean both sides. For confirmation, use a bright light to identify any spots left.

Step 6: Get the right tools

To remove the encapsulation and the screws to clean, make sure you have the right tools. The presence of screwdrivers, soap water, vacuum cleaner, and hoses of appropriate sizes are necessary for cleaning purposes.

Furthermore, if the paper air filter is damaged, it is highly recommended to replace it rather than cleaning it as they are very fragile and comparatively extremely cheap.

Step 7: Clean the encapsulation

After the air filter has been thoroughly cleaned, the next step is to ensure that the gasket or the encapsulation is free from any debris or dust. In this regard, use a vacuum cleaner and soap water to clean it. Also, make sure that the gasket does not has any leaks so that it is safe from dust and debris and the cleaned air filter remains protected.

Step 8: Reassemble

To keep track of all the screws and parts, it is advised to keep a bowl for storing them so that you might not lose them. Once you are done with the cleaning and replacement, step the gasket back together and place it where you removed it.
