Maintenance
Maintenance Safety
-
Shut off the machine and wait for all moving parts to stop before you leave the operator’s position. Allow the machine to cool before adjusting, fueling, unclogging, servicing, cleaning, or storing it.
-
Disconnect the spark-plug wire from the spark plug before performing any maintenance procedure.
-
Never tamper with safety devices. Check their proper operation regularly.
-
Keep all nuts, bolts and screws tight to ensure that the machine is in safe working condition.
-
Replace a faulty muffler.
-
Tipping the machine may cause the fuel to leak. Fuel is flammable and explosive, and can cause personal injury. Run the engine dry or remove the fuel with a hand pump; never siphon the fuel.
-
Inspect the machine regularly and replace worn or damaged parts. Ensure that parts are not bent, damaged, or loose.
-
To ensure optimum performance of the machine, use only genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers could be dangerous, and such use could void the product warranty.

Pre-Maintenance Procedures
Preparing for Maintenance
-
Move the machine to a level surface, shut off the engine, and wait for all moving parts to stop.
-
Disconnect the spark-plug wire from the spark plug.
-
After performing the maintenance procedure(s), connect the spark-plug wire to the spark plug.
Important: Before tipping the machine, allow the fuel tank to run dry through normal usage. If you must tip the machine prior to running out of fuel, use a hand fuel pump to remove the fuel.
Engine Maintenance
Servicing the Air Cleaner
Maintenance Service Interval | Maintenance Procedure |
---|---|
Every 25 hours |
|
-
Refer to Preparing for Maintenance.
-
Remove the air-cleaner cover.
-
Remove and inspect the air-cleaner elements.
-
Inspect the air-cleaner elements.
-
Replace any torn or worn element. Otherwise, clean each element as follows:
-
Wash the element with warm water and a mild detergent.
Important: Press the element when washing it; do not twist it.
-
Dry the element by pressing it in a clean cloth.
-
Thoroughly oil the foam element using new engine oil and press out any excess oil.
-
-
Install the elements, screen, and air-cleaner cover to the base.
Servicing the Engine Oil
Engine-Oil Specifications
Engine oil capacity | 0.35 L (11.8 fl oz) |
Oil viscosity | Refer to the chart below. |
API service classification | SJ or higher |
Important: Do not use SAE 10W-40 Motor Oil.
Checking the Engine-Oil Level
Maintenance Service Interval | Maintenance Procedure |
---|---|
Before each use or daily |
|
-
Move the machine to a level surface.
-
Remove the dipstick.
-
Wipe the dipstick clean with a clean cloth.
-
Insert the dipstick into the oil-fill tube and tighten it.
-
Remove the dipstick and check the engine-oil level.
-
If the oil level is low, slowly add oil into the filler tube until the level is at the top thread of the tube.
-
Insert the dipstick into the oil-fill tube and tighten it.
Changing the Engine Oil
Maintenance Service Interval | Maintenance Procedure |
---|---|
After the first 20 hours |
|
Every 25 hours |
|
Every 50 hours |
|
Note: Run the engine a few minutes before changing the oil to warm it. Warm oil flows better and carries more contaminants.
-
Move the machine to a level surface.
-
Refer to Preparing for Maintenance.
-
Place a pan under the drain plug to catch the oil.
-
Remove the oil-fill plug and allow the oil to drain.
Note: Dispose of the used oil at a certified recycling center.
-
Install the oil-fill plug.
-
Slowly pour oil into the oil-fill hole until the oil is at the correct level; refer to Engine-Oil Specifications.
-
Ensure that the oil is at the correct level on the dipstick; refer to Checking the Engine-Oil Level.
-
Wipe up any spilled oil.
Servicing the Spark Plug
Maintenance Service Interval | Maintenance Procedure |
---|---|
Every 50 hours |
|
Ensure that the air gap between the center and side electrodes is correct before installing the spark plug.
Use a spark plug wrench for removing and installing the spark plug(s) and a gapping tool/feeler gauge to check and adjust the air gap. Install a new spark plug(s) if necessary.
Type: LG E5RTC
Air gap: 0.75 mm (0.03 inch)
Removing the Spark Plug
-
Disconnect the spark-plug wire from the spark plug.
-
Clean around the spark plugs to prevent dirt from entering the engine and potentially causing damage.
-
Remove the spark plug.
Checking the Spark Plug
Important: Do not clean the spark plug(s). Always replace the spark plug(s) when it has a black coating, worn electrodes, an oily film, or cracks.
If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty.
Set the gap to 0.75 mm (0.03 inch).
Installing the Spark Plug
-
Thread the spark plug clockwise into the spark-plug hole by hand.
-
Rotate the spark plug clockwise using a spark-plug wrench until the plug and sealing washer are seated.
-
Tighten the spark plug as follows:
-
When installing the original spark plug, tighten the plug an additional 1/2 turn.
-
When installing a new spark plug, tighten the plug an additional 1/8 to 1/4 turn.
Important: A loose spark plug may cause the cylinder to overheat. An over-tight spark plug may damage the threads in the cylinder head.
-
-
Connect the spark-plug wire to the spark plug.
