|
Known Issues
|
Common Wear Items:
|
Forklift wear items include tires, brake pads, hydraulic hoses, mast rollers, and operator controls.
|
Hydraulic System Issues:
|
Slow lifting, tilting, or steering can indicate low fluid, pump wear, or valve issues.
|
Engine Performance Issues:
|
Loss of power, rough running, or excessive smoke often point to fuel system issues, air intake problems, or turbocharger wear (if equipped).
