Why is my Komatsu Excavators overheating?
Overheating can occur if the oil level is too low or too high. Ensure the oil is at the correct level according to specifications. Also, check if the machine is being driven in too high a gear; if so, use a lower gear. Engine overheating can also be a cause.
What causes unusual combustion noises and mechanical noises in Komatsu WA270-3H?
Unusual combustion and mechanical noises can be attributed to several factors: using incorrect fuel, overheating, a faulty silencer (which would need replacing), or excessive valve clearance (which requires adjustment).
What to do if the warning lamp for oil pressure lights up with the engine running on my Komatsu WA270-3H?
If the warning lamp illuminates while the engine is running, it could be due to several reasons. First, check if the oil level is too low and top it up if necessary. Another potential cause is a dirty oil filter cartridge, which should be replaced. Also, inspect the oil pipe connection for any faults and repair them. Finally, the pressure sensor may be faulty and require replacement.
