OPERATION
CHECK FUEL LEVEL, ADD FUEL
When adding fuel, take care that it will not overflow. Overflow of fuel can cause a fire. If any fuel spills, wipe it off.
If fuel spills onto dirt and sand sticking to the machine, remove it and dirt and sand together.
Since fuel is flammable and dangerous, do not bring fire near it.
1. Check with fuel gauge (1) on the machine monitor.
2. After completing operations, add fuel through fuel filler (F) to fill
the tank.
Fuel tank capacity: 384 liters (101.45 US gal)
3. After adding fuel, tighten the cap securely.
REMARK
If the breather hole in the cap 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 BOLTS, TIGHTEN
Check for loose wheel hub bolts (1). If any are found, tighten them.
Tightening torque: 824 to 1030 Nm
(84 to 105 kgm, 607.6 to 759.5 lbft)
Insert a socket wrench in a pipe, and apply a force of 932 N (95 kg)
at a point 1 m from the fulcrum to give a tightening torque of 932 Nm
(95 kgm, 687.1 lbft).
When tightening the hub bolts 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 wheel bolt is broken, replace all the wheel bolts for that
wheel.
