Pre-Operation Checks; Fuel Recommendation - Honda HP400 Owner's Manual

Fuel Recommendation
Check the power carrier on level ground with the engine stopped.
Unscrew the fuel tank cap, and check the fuel level. Refill the tank if the fuel
level is low. Do not fill above the UPPER LEVEL.
Gasoline is extremely flammable and is explosive under certain
conditions.
Refuel in a well-ventilated area with the engine stopped. Do not
smoke or allow flames or sparks in the area where the engine is
refueled or where gasoline is stored.
Do not overfill the fuel tank (there should be no fuel in the filler neck).
After refueling, make sure the tank cap is closed properly and
securely.
Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor
may ignite. If any fuel is spilled, make sure the area is dry before
starting the engine.
Avoid repeated or prolonged contact with skin or breathing of vapor.
KEEP OUT OF REACH OF CHILDREN.

Use gasoline with a pump octane rating of 86 or higher
We recommend unleaded gasoline because it produces fewer engine and
spark plug deposits and extends exhaust system life.
Never use stale or contaminated gasoline or oil/gasoline mixture. Avoid
getting dirt or water in the fuel tank.
