Heli CPD35 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A major fault or unsafe condition has been detected in the CPD35’s systems, requiring immediate shutdown. | Stop the forklift right away and investigate the cause using the display or service manual. | |
| Check Engine (MIL) | AMBER | The forklift’s controller has detected an issue with the electric drive or related electronics. | Note any symptoms and schedule a diagnostic check with a qualified Heli technician. | |
| Battery / Charging | RED | The traction battery voltage is critically low or the charging system is malfunctioning. | Safely park the CPD35 and connect it to the charger; do not continue operation. | |
| Brake System | RED | A fault has been detected in the CPD35’s brake system, affecting stopping ability. | Cease operation immediately and arrange for a brake system inspection. | |
| Parking Brake | RED | The parking brake is engaged or not fully released while the forklift is on. | Release the parking brake before driving; if the light stays on, check for a fault. | |
| Hydraulic System | AMBER | The hydraulic system has detected abnormal pressure or temperature in the CPD35. | Monitor function and schedule service if performance is affected. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or quality is below specification, risking lift or tilt issues. | Top up or replace hydraulic oil as soon as possible and check for leaks. | |
| Service / Hour Meter | AMBER | The CPD35 has reached a service interval based on operating hours. | Schedule routine maintenance to keep the forklift in peak condition. | |
| Overload / Capacity | RED | The load weight exceeds the safe lifting capacity set for the CPD35. | Lower the load immediately to prevent tipping or equipment damage. | |
| Battery Discharge (BDI) | AMBER | The traction battery charge is low, approaching the minimum safe operating limit. | Plan to complete your task and recharge the battery soon. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum safe height or tilt angle on the CPD35. | Avoid further lifting or tilting and lower the mast if safe to do so. | |
| Low Fuel | AMBER | The battery charge is nearly depleted, signaling limited remaining run time. | Recharge the battery at the next opportunity to avoid a work stoppage. | |
| Work Lights | GREEN | The CPD35’s work lights are switched on for improved visibility. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The warning beacon is active, alerting others to forklift operation. | Ensure the beacon is functioning in areas with pedestrian or vehicle traffic. | |
| Fasten Seat Belt | AMBER | The operator’s seat belt is not fastened while the CPD35 is powered on. | Secure your seat belt before moving the forklift. |

Most Important Warning Lights
Battery / Charging
Common causes
- Battery charge dropped below safe threshold
- Charger or charging port malfunction
- Damaged battery cells
What to do
Immediately stop using the forklift and connect it to an approved charger. If the issue persists after charging, have the battery and charging system checked by Heli service personnel.
Brake System
Common causes
- Low brake fluid
- Worn brake pads or shoes
- Malfunction in the hydraulic or electric brake system
What to do
Do not operate the CPD35 until the brake system has been inspected and repaired by a qualified technician; check fluid levels and look for visible leaks.
Overload / Capacity
Common causes
- Attempting to lift a load above rated capacity
- Incorrect load center
- Faulty load sensor
What to do
Immediately lower the load to a safe weight and verify load limits using the data plate. If the warning persists with lighter loads, have the load sensor calibrated.
Master Warning (Stop)
Common causes
- Critical system fault detected
- Severe electrical or hydraulic failure
- Multiple simultaneous alerts
What to do
Turn off the forklift and consult the error code displayed. Contact Heli support for guided troubleshooting before restarting.
Frequently Asked Questions
What should I do if the Battery Discharge (BDI) light comes on during a shift?
Plan to finish your current task and recharge the forklift as soon as possible; running the CPD35 with low battery can shorten battery life.
Is it safe to keep working when the hydraulic oil light appears?
No, you should check and top up the hydraulic oil at the next opportunity to avoid damage or impaired hydraulic functions.
Why does the overload light activate even when the load seems normal?
Check that the load is within the rated capacity and properly centered; if the warning stays on, the load sensor may need adjustment.
How often should I schedule maintenance when the hour meter indicator lights up?
Follow the maintenance interval in the CPD35 manual, typically every 250 hours, to ensure reliability and safety.
What does it mean if the master warning light appears with no other symptoms?
A hidden system fault may be present; check the display for error codes and consult Heli service if the cause isn’t obvious.
