Most Important Warning Lights
Overload / Capacity
Common causes
- Attempting to lift a load heavier than the EFG 425's rated capacity
- Incorrect load distribution on forks
- Load positioned too far from the mast
What to do
Lower the load and reposition it within the rated limits; always verify load weight and placement before lifting with the EFG 425.
Brake System
Common causes
- Hydraulic brake fluid leak
- Worn brake pads or components
- Brake actuator malfunction
What to do
Inspect the EFG 425's brake system for leaks or worn parts and repair immediately to ensure safe stopping.
Hydraulic System
Common causes
- Low hydraulic fluid level
- Damaged hydraulic hose or fitting
- Hydraulic pump failure
What to do
Check and refill hydraulic fluid, inspect hoses for damage, and have the hydraulic system serviced if faults persist.
Battery Discharge (BDI)
Common causes
- Prolonged use without recharging
- Faulty battery cell or connector
- Charger malfunction
What to do
Recharge the battery fully and inspect for any battery or charging system issues before next use.
Frequently Asked Questions
What should I do if the battery discharge indicator comes on?
Return the EFG 425 to the charging station and recharge the battery before continuing work.
Why is the overload light illuminated even with a light load?
The load might be positioned too far from the mast or the sensor may need calibration; check load placement and consult service if the issue remains.
Can I keep operating if the master caution light is on?
You may continue operating briefly, but inspect the display for fault details and arrange maintenance soon to avoid further issues.
How often does the hour meter trigger service alerts?
Service intervals are based on operating hours; check your EFG 425 manual for specific intervals and follow the on-screen reminders.
What does it mean if the hydraulic oil light stays on?
This indicates the hydraulic oil is either low or too hot; stop and check oil level and temperature before resuming operation.
