Air Filters 101
Skid steers and compact track loaders encounter many jobsite contaminants, including dirt and dust, which can cause engine damage. By correctly installing air filters at regularly scheduled intervals, you'll help protect your engine and ensure long life.
First and foremost, be sure to carefully follow the procedures in your machine's operator manual. The following tips highlight some of the important things you need to know:
Tip 1: Time for a change.
Change air filters according to the recommended hours for your equipment. For new E-Series machines, air filters should be changed as soon as indicated by the air-restriction light on the monitor.
Tip 2: Check the dust-unloader valve.
Squeeze the dust-unloader valve to remove dust from the air filter. If the unloader valve appears worn or damaged, replace it.
Tip 3: Carefully remove and discard.
After removing the service cover, gently move the end of the air filter back and forth to break the seal. Gently pull the filter out of the housing, taking care not to knock the filter against the housing and dislodging contaminants.
Tip 4: Clean the air-filter housing.
DO NOT use compressed air as debris could enter the engine and cause damage.
Tip 5: Install the primary filter.
Gently slide the primary filter over the secondary filter and press it into place until fully seated. Apply pressure by hand at the filter's outer rim to complete a tight seal. To ensure sealing pressure has been distributed evenly to the critical sealing area, continue pushing the filter into the outlet tube until the filter stops.
Tip 6: Check service cover.
If it does not fit flush to the air-filter housing the primary filter is not properly seated. Do not force the service cover into place.
Tip 7: Check air-filter restriction.
After inspecting and torqueing the entire air-intake system, check the air-filter restriction indicator on the monitor. Replace the secondary filter if the indicator shows restriction.
