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 are the first and foremost tasks once we 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, which could eventually help look for the correct replacements it needs. The method to clean the air filters varies from machine to machine.

This is because each machine uses either a single paper air filter or a dual air filter that combines paper and foam air filters. 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, which helps you identify its parts to pinpoint where an air filter is present and help you with necessary information about its components.

In turn, allow you to gather supplies for a replacement if necessary. Turning off or disconnecting the lawnmower is the next step, which is more of a safety precaution. This step is essential as many lawnmower parts might be operational even though the machine has not started.

● Step 3: Remove / Disconnect the spark plugs

Like the previous step, this step is 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 found, 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 usually 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.

Remove a vacuum cleaner and attach a hose to the appropriate site. 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. Screwdrivers, soap water, vacuum cleaners, and hoses of appropriate sizes are necessary for cleaning.

Furthermore, if the paper air filter is damaged, replacing it rather than cleaning it is highly recommended as it is very fragile and comparatively cheap.

● Step 7: Clean the encapsulation

After the air filter has been thoroughly cleaned, the next step is to ensure that the gasket or encapsulation is free from debris or dust. In this regard, use a vacuum cleaner and soap water to clean it.

Also, ensure that the gasket has no leaks so 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.

Set the spark plugs back together and make the necessary connection to set the lawnmower in the starting position.
