OPERATION
CHECK FUEL LEVEL, ADD FUEL
WARNING
When adding fuel, never let the fuel overflow. This may cause a fire. If any
fuel is spilled, wipe it up completely. Never bring flames near fuel because
it is highly flammable and dangerous.
1. Check the fuel level with fuel gauge (G), which is installed in the
side of the fuel tank.
2. After completing operations, add fuel through fuel filler (F) to fill
the tank.
Fuel capacity: 500 liters (132.1 US gal)
3. After adding fuel, tighten the cap securely.
REMARK
If the breather hole in the cap (1) becomes clogged, the
pressure inside the tank will go down and the fuel may not flow,
therefore clean the breather hole from time to time.
To prevent air from being sucked into the engine, do not let the
level in the fuel tank go down too low.
CHECK WHEEL HUB NUTS, TIGHTEN
Check for loose wheel hub nuts (1). If any are found, tighten them.
Tightening torque: 1520 to 1850 Nm
(155 to 189 kgm, 1121 to 1367 lbft)
Insert a socket wrench in a pipe, and apply a force of 1740 N (177
kg) at a point 1 m from the fulcrum to give a tightening torque of
1740 Nm (177 kgm, 1280 lbft).
When tightening the hub nuts after replacing the tires, travel for 5
to 6 km, then check the tightening torque to ensure that there are
no loose bolts.
If any stud bolt used to install the rim is broken, replace all the stud
bolts for that wheel.
