Changing Engine Oil On Briggs & Stratton Models
For draining oil from the engine's crankcase, a plastic oil drain
sleeve is packed with this Operator's Manual. To drain the oil,
proceed as follows:
1. Run the engine for a few minutes to allow the oil in the
crankcase to warm up. Warm oil will flow more freely and
carry away more of the engine sediment which may have
settled at the bottom of the crankcase. Use care to avoid
burns from hot oil.
2. Open the tractor's hood and locate the oil drain port on the
right side of the engine and the oil fill cap on the topside of
the engine.
3. Unscrew the oil fill cap and remove the dipstick from the oil fill
tube.
4. Snap the small end of oil drain sleeve onto the space
provide around the oil drain plug. See Figure 6-1.
5. Remove drain plug and drain oil into a suitable container
with a capacity of no less than 64 oz.

your unit for information regarding the quantity and proper
viscosity of motor oil.
Changing The Engine Oil on Kohler Engine Models
To complete an oil change, proceed as follows:
1. Run the engine for a few minutes to allow the oil in the
crankcase to warm up. Warm oil will flow more freely and
carry away more of the engine sediment which may have
settled at the bottom of the crankcase. Use care to avoid
burns from hot oil.
2. Open the tractor's hood and locate the oil drain port on the
right side of the engine.
3. Pop open the protective cap on the end of the oil drain
valve to expose the drain port. Figure 6-2.
4. Remove the oil fill cap/ dipstick from the oil fill tube.
5. Push the oil drain hose (packed with this manual) onto the
oil drain port. Route the opposite end of the hose into an
appropriate oil collection container with at least a 2.5 quart
capacity, to collect the used oil.
6. Rotate the drain valve counter-clockwise and release to
drain the oil. See Figure 6-2.

7. After the oil has finished draining, push the end of the oil
drain valve back in, until the tabs click into place. Re-cap
the end of the oil drain valve to keep debris from entering
the drain port.
