TROUBLESHOOTING OF THE ENGINE AND OTHER SYSTEMS
If the machine does not perform as expected, or if trouble arises, see the following table and undertake appropriate
measures.
Trouble Cause Countermeasure
Engine
Starting difficulties
Fuel is too viscous.
• Check the fuel tank and the filter.
•
Remove the impurities and the water.
• If necessary, replace the filter.
Air or water in the fuel system
• Remove the water from the fuel tank.
• Check the fuel-pipe-joint-bolts and nuts for looseness.
• Purging of the fuel system as the fuel filter and the
supply pump. See Purging of the fuel system on page
108.
Fuse is blown out.
• Check the fuse and replace it with a same-capacity
one as required.
Oil viscosity is too high the engine
runs sluggishly in winter.
• Use the engine block heater (option).
Battery is almost dead causing insuffi-
cient compression.
• Recharge the battery.
Insufficient engine power
Low fuel level • Check the fuel and add it if necessary.
Clogged air cleaner • Clean the air-cleaner-element.
Engine suddenly stops. Low fuel level
• Check the fuel and add it if necessary.
• Purge the fuel system.
Abnormal exhaust gas
color
Use of poor fuel • Use the prescribed fuel.
Too much engine oil • Drain engine oil to prescribed level.
Water temperature in red
zone (Overheating)
Flawed seal of the water pump • Replace the seal of the water pump.
Worn or torn V-belt • Adjust or replace the V-belt.
Thermostat is flawed. • Replace the thermostat.
Coolant level too low
• Fill the recovery tank with the coolant to prescribed
level.
Radiator grill or fins are clogged. • Clean the radiator grill or fins.
Coolant is contaminated with rust
from the cylinder head or crank case.
• Replace coolant fluid and add anti-rust.
Flawed radiator cap (Evaporation) • Replace the radiator cap.
Corroded coolant pipes • Clean or replace the coolant pipes.
Continuous operation under full load • Reduce the load.
Cylinder-head-gasket is damaged
(Coolant loss).
• Replace the cylinder-head-gasket.
Engine oil level too low • Fill the engine with the engine oil to prescribed level.
Maladjustment of the fuel injection • Readjust the fuel injection in ignition timing.
Use of poor fuel • Use the prescribed fuel.
Hydraulic System
Lift arms, bucket, or drive
unit power is too low
.
Hydraulic oil level too low • Add the hydraulic oil to the prescribed level.
Leakages of the hoses and / or the
joints
• Replace the hose and/or the joint.
Clogged oil filter • Replace the oil filter.
Lift arms, bucket, or drive
unit can not move.
Armrest is in the raised position. • Lower the armrests.
Operator is not in the operator's seat. • Sit in the operator's seat.
