Frequently Asked Questions
What should I do if the Battery Discharge Indicator lights up on my GEX40?
Plan to complete your current task and move the forklift to a charging station before the battery is fully depleted.
Can I keep operating if the ABS light stays on?
You can continue, but drive with extra caution as the anti-lock braking feature is disabled; arrange for service soon.
Why is the Mast/Lift Limit light flashing?
This indicates the mast has reached its maximum lift height or an obstruction is detected; lower the mast or clear any blockages.
How often does the GEX40 require maintenance as indicated by the hour meter?
Service intervals are based on operating hours; refer to your Clark GEX40 manual for the specific schedule.
Is it safe to operate the GEX40 if the hydraulic warning is on?
No, check for low hydraulic fluid or leaks immediately and resolve the issue before operating to prevent system damage.
