FUEL
TYPE–
No. 2 diesel fuel is recommended for the best economy and performance under most operating
conditions. In operating conditions under 32°F, use a blend of No. 1 and No. 2 diesel fuel. The addition of No.
1 diesel fuel may cause loss of power and/or fuel economy.
STORING-
See section 6 on storage.
REFUELING–
Always turn off the engine and allow it to cool
before refueling. Never smoke while fueling. Keep a fire extin-
guisher within reach while refueling.
The fuel cell on GST 20 holds 150 gallons– do not fill it completely: fuel can expand and run over. Wipe up
all spilled fuel and clean with detergent and water before starting the engine.
DELUGE SOLUTION
The deluge system should be checked daily using the tank
level sight gauge (fig. 7.86.1, item 1). Fill it as required with deluge
solution or approved windshield washing solution.
To fill the tank, open the 2” ball valve on the top and add de-
sired amount of solution (fig. 7.86.1, item 2).
Check the nozzles for wear, damage, or blockage during rou-
tine maintenance or if they begin to spray erratically. The nozzles
for the side windows are located on the light brackets (fig. 7.86.3)
and the nozzles for the front windshield are mounted on the front
panel (fig.7.86.4). There are six nozzles mounted around the cab.
The electric motor for the system is located on the back of the mount-
ing bracket (fig. 7.86.2)
