• Check the engine-oil level and add oil as needed.
• Ensure that the engine shuts off within 3 seconds after releasing the blade-control
bar.
After each use
• Clean grass clippings and dirt from under the machine.
Every 25 hours
• Service the air filter; service it more frequently in dusty operating conditions.
• Charge the battery for 24 hours (electric-start model only).
Every 100 hours
• Replace the spark plug.
Before storage
• Empty the fuel tank before repairs as directed and before yearly storage.
Yearly
• Replace the air filter; replace it more frequently in dusty operating conditions.
• Change the engine oil (if desired).
• Replace the blade or have it sharpened (more frequently if the edge dulls quickly).
Important:
Refer to your engine manual for additional maintenance procedures.
Maintenance Safety
•
Always shut off the machine, wait for all moving
parts to stop, and allow the machine to cool before
adjusting, servicing, cleaning, or storing it.
•
Disconnect the spark-plug wire from the spark plug
and remove the ignition key (if equipped) before
performing any maintenance procedure.
•
Wear gloves and eye protection when servicing
the machine.
•
The blade is sharp; contacting the blade can result
in serious personal injury. Wear gloves when
servicing the blade. Do not repair or alter the
blade(s).
•
Never tamper with safety devices. Check their
proper operation regularly.
•
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.
•
To ensure optimum performance of the machine,
use only genuine Lawn-Boy replacement parts and
accessories. Replacement parts and accessories
made by other manufacturers could be dangerous,
and such use could void the product warranty.

Important:
Before tipping the machine to
change the oil or replace the blade, 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. Always tip the machine onto its side
with the dipstick down.
