Frequently Asked Questions
What should I do if the master warning light comes on while operating the 8FGCU18?
Stop the forklift immediately in a safe location and investigate the cause, as this indicates a critical fault or hazard.
Can I continue working if the check engine light is on?
While the forklift may still operate, it's best to schedule a service soon as continued use can cause further damage or emissions issues.
What does the overload warning mean?
This light means the forklift is carrying or attempting to lift a load above its safe rated capacity; immediately lower the load to prevent tipping or damage.
How often should I check fluid levels on the 8FGCU18?
Check engine oil, coolant, brake, and hydraulic fluid levels daily before starting your shift to avoid unexpected warnings or breakdowns.
Why does the seat belt light stay on even when I'm seated?
Ensure the seat belt is fully latched; if the light remains, the seat switch or belt sensor may need inspection.
