Checking/Adding Fuel; Fuel Filter; Change Oil & Filter - Briggs & Stratton Snapper Pro S800X Series Operator's Manual

Checking / Adding Fuel
To add fuel:
1. Remove the fuel cap.
2. Fill the tank to about 1-1/2" (3,81 cm) from the bottom
of the filler neck. This will allow for fuel expansion.
NOTE: Do not overfill. Refer to your engine manual for
specific fuel recommendations.
3. Install and hand tighten the fuel cap.

Fuel Filter

The fuel filter is located in the fuel line between the fuel tank
and the carburetor, near the fuel pump. If filter is dirty or
clogged, replace as follows:
1. Disconnect the negative battery cable.
2. Place a container below the filter to catch any spilled
fuel.
3. Using pliers, open and slide the hose clamps from the
fuel filter (C, Figure 18).
4. Remove the hoses from the fuel filter.
5. Install the new fuel filter in the proper flow direction in
the fuel line.
6. Secure with the hose clamps.
7. Reconnect the negative battery cable when finished.
Change Oil & Filter
1. Warm engine by running for a few minutes. (Refer
to the engine operator's manual for oil and filter
replacement instructions.)
2. Locate the oil drain hose (A, Figure 18) on the left side
of the engine and route the oil drain hose down through
the frame towards the ground.
3. Place a small pan under the oil drain hose to catch the
oil. Using the appropriate tools, remove the cap (B)
from the oil drain hose (A) and drain the engine oil into
the pan.
4. After draining, replace the cap and wipe up any spilled
oil. Route the oil drain through the hose clamp and
towards the rear of the machine so the oil drain hose is
retained during normal operation.
5. Place an absorbent shop cloth under the engine oil filter
(D). Remove the engine oil filter and replace with a new
one.
6. Remove the engine oil fill cap (F) that is located on the
right side of the engine and refill with new oil (Refer to
the engine operator's manual for oil recommendations.)
7. Remove the shop cloth and wipe up any spilled oil.
WARNING
Fuel and its vapors are extremely
flammable and explosive.
Fire or explosion can cause severe burns
or death.
• Gasoline is highly flammable and must be handled with
care. Never fill the tank when the engine is still hot from
recent operation. Do NOT allow open flame, smoking or
matches in the area. Avoid over-filling and wipe up any
spills.
• Do NOT remove fuel filter when 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.
NOTICE
Do not use gasoline containing METHANOL, gasohol
containing more than 10% ethanol, gasoline additives,
premium gasoline, or white gas because engine/fuel
system damage could result.
