BBleeding the fuel system
To avoid personal injury or death:
A Keep sparks and flames away from the fuel, or
serious personal injury may result.
After the fuel tank has been run empty or maintenance
and service work has been carried out, the engine cannot
be started again after refueling. This is because air has
entered the fuel system. It is thus necessary to bleed the
fuel system in the following manner:
1. Fill the fuel tank with fuel.
2. Turn the starter switch to the "RUN" position. The fuel
pump starts working to supply fuel into the line. About
10 seconds later, the air will be bled out from the line.
3. Start the engine.
A The engine may sometimes stall after starting if air
bleeding was not complete. If this should occur, repeat
step (2) and step (3).
TIRES
BHandling tires
To avoid personal injury or death:
A Before changing tires, stop the engine, lower
the bucket and attachment to the ground,
release the hydraulic pressure in the hydraulic
system by operating the control levers, lock all
control levers in neutral, and remove the key.
A To change tires, place the machine on blocks
suitable for the weight of the machine.
A Before adding air, have the tire correctly
installed on the machine or put the tire in a
retaining device (tire inflation cage). Do not
blow up tires with greater pressure than
specified in the table as a blown tire can cause
serious injury.
BTire pressure
If the air pressure in the tire is too high or too low, the life
of the tire will be shortened. Make routine checks of the air
pressure in tires. Check the tires and rims for damage and
eliminate defects before starting operation.
C Tire pressure
(1) Deficient
(2) Correct
(3) Excessive
(4) Ground level
