Fire or explosion can cause severe burns or death.
Do NOT remove the fuel filter when the engine is hot, as
spilled gasoline may ignite. Do NOT spread hose clamps
further than necessary. Ensure clamps grip hoses firmly
over filter after installation.
Carbureated Models: The fuel filter is located in the fuel line
between fuel tank and carburetor, near the fuel pump.

between the fuel tank and fuel pump.

Briggs & Stratton Vanguard Engines
with Remote Oil Tank (Select Models)
Some models in this series of mower feature a remote oil tank
(A, Figure 29) that supplies oil to the engine. Units equipped
with a Vanguard engine with remote oil tank are factory filled
with specially formulated Vanguard 15W-50 synthetic oil.
Note: This specific grade of oil is not required to keep engine
warranty in effect.
For more information regarding this engine and other
operational and maintenance information, please refer to the
engine operator's manual included with your unit.

Changing the Engine Oil and Filter
(Engines with Remote Oil Tank)
Engine Oil Type: 15W-50 synthetic oil. (See the engine
operator's manual for other oil recommendations.)
Engine Oil Change Amount: 5 qt (4,73 L).
Oil Change Interval: Every 500 hours.
Important: Always make sure that the mower is parked on a
flat, level surface when checking the engine oil level.
1. Park the machine on a flat, level surface. Engage the
parking brake and disengage the PTO. Allow the engine
to run until it is warm. This will warm the oil so it will
drain better. Turn the ignition switch to OFF, remove the
ignition key, and wait for all moving parts to stop before
leaving the operator's position.
2. Clean the area around the engine oil dipstick (A, Figure
30) and oil fill cover (B) to remove any debris.
