DANGER
Because diesel fuel is highly flammable, use cau-
tion when storing or handling it. Do not smoke
while filling the fuel tank. Do not fill fuel tank
while engine is running or hot, or when machine
is in an enclosed area. Always fill fuel tank out-
side and wipe up any spilled diesel fuel before
starting the engine. Store fuel in a clean, safety-
approved container and keep cap in place. Use
diesel fuel for the engine only; not for any other
purpose.
Check Fuel Lines and Connections
Check fuel lines and connections at intervals recom-
mended in your Operator's Manual.
1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake, and remove key
from the ignition switch. Unlatch and raise hood.
2. Check fuel lines for deterioration, damage, leaks, or
loose connections. Replace hoses, clamps, and con-
nections as necessary.

taminated or if the machine is to be stored for an ex-
tended period.

Removal).
2. Flush fuel tank out with clean diesel fuel. Make sure
tank is free of contaminates and debris.

lation).
