Do not operate the truck; have the brake system inspected and repaired by a qualified technician to restore safe braking performance.
Battery Discharge (BDI)
Common causes
- Extended operation without recharging
- Battery nearing end of charge cycle
- Malfunction in charging system
What to do
Recharge the traction battery as soon as possible to prevent automatic speed reduction and maintain forklift productivity.
Hydraulic System
Common causes
- Low hydraulic oil level
- Hydraulic leak
- Faulty hydraulic pump
What to do
