Bobcat Telehandler V519 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical fault has been detected requiring immediate shutdown of the V519 to prevent system damage. | Stop engine safely and address the underlying issue before restarting. | |
| Master Caution | AMBER | A non-critical fault is present on the V519 that requires attention soon to avoid escalation. | Check other warning lights and service the machine as needed. | |
| Check Engine (MIL) | AMBER | The engine management system on the V519 has detected a fault in emissions or performance. | Have the engine diagnosed by a Bobcat dealer to prevent further issues. | |
| Engine Oil Pressure | RED | Engine oil pressure is below safe level in the V519, risking severe engine damage. | Immediately stop the engine and check oil level and system for leaks. | |
| Battery / Charging | RED | The V519's charging system is not working properly, possibly due to alternator or battery failure. | Check battery connections and have the charging system tested. | |
| Coolant Temperature | RED | Engine coolant temperature in the V519 is above normal operating range, risking overheating. | Stop engine, allow to cool, and check coolant level and radiator for blockages. | |
| Transmission Temp | AMBER | Transmission fluid temperature is high in the V519; prolonged operation may cause damage. | Reduce load and allow transmission to cool; check fluid level and cleanliness. | |
| Brake System | RED | A fault in the brake system of the V519 has been detected, potentially reducing braking performance. | Stop machine immediately and have brakes inspected before further use. | |
| Parking Brake | RED | The parking brake on the V519 is engaged or a fault exists in the parking brake system. | Ensure parking brake is disengaged before moving; if light stays on, service brake system. | |
| Glow Plug / Preheat | AMBER | The glow plugs on the V519 are active for cold start preheating, or a fault in the system. | Wait for the light to turn off before cranking; if it flashes, have glow plugs checked. | |
| DPF / Regeneration | AMBER | The diesel particulate filter on the V519 needs regeneration, or a regeneration is in progress. | If flashing, operate at high load to initiate regen; if steady, perform parked regen as per manual. | |
| DEF / AdBlue | AMBER | Diesel exhaust fluid level is low or system fault on the V519, affecting emissions compliance. | Refill DEF or consult dealer if system error persists. | |
| Water in Fuel | AMBER | Water has been detected in the fuel system of the V519, which can damage injectors. | Drain water from the fuel filter separator immediately. | |
| Low Fuel | AMBER | Fuel level in the V519 is low; refuel to avoid running out during operation. | Refuel as soon as possible to prevent air in the fuel system. | |
| High Beam | BLUE | The high beam headlights on the V519 are switched on for enhanced visibility. | No action needed; dim when approaching other vehicles or personnel. | |
| Hydraulic System | RED | A critical fault in the hydraulic system of the V519 has been detected, affecting lift and steering. | Stop machine and check hydraulic oil level and for leaks; do not operate until resolved. | |
| Seat Belt | RED | The seat belt on the V519 is not fastened, or a fault in the interlock system exists. | Fasten seat belt immediately; if light stays on, inspect belt and sensor. | |
| Work Lights | GREEN | The work lights or auxiliary lighting on the V519 are turned on for low-light operation. | No action needed; turn off when not required to save battery. | |
| Beacon / Rotating Light | GREEN | The rotating beacon on the V519 is active, indicating the machine is in operation. | No action needed; ensure beacon is functional for safety compliance. | |
| Swing / Slew Lock | AMBER | The swing lock on the V519 is engaged, preventing telescopic arm rotation. | Release swing lock before attempting to rotate the boom. | |
| Overload / Capacity | RED | The V519 is overloaded or load moment exceeds safe limits; risk of tipping. | Reduce load immediately or reposition to lower moment; do not lift additional weight. | |
| Mast / Lift Limit | AMBER | The V519's mast or lift position is near maximum safe limit, or a limit switch is activated. | Lower or retract boom to safe position; check for obstructions. | |
| Service / Hour Meter | AMBER | Scheduled maintenance interval on the V519 has been reached based on operating hours. | Perform required maintenance per Bobcat service schedule. | |
| Differential Lock | AMBER | The differential lock on the V519 is engaged for increased traction in low-grip conditions. | Disengage when not needed to prevent driveline binding. | |
| Reduced Power (Limp Mode) | AMBER | The V519 engine has entered a derated mode to protect against fault conditions. | Reduce load and drive slowly to service location; check for active faults. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator blockage
- Faulty cooling fan or thermostat
What to do
Stop the V519 immediately and let it cool. Check coolant level and radiator fins. If recurring, have the cooling system inspected by a Bobcat dealer.
Hydraulic System Failure
Common causes
- Low hydraulic oil
- Contaminated oil
- Hydraulic pump or valve fault
What to do
Shut down the V519 and check hydraulic oil level and condition. Inspect for leaks in hoses and fittings. Do not operate until repaired by a qualified technician.
Overload Condition
Common causes
- Exceeding rated load capacity
- Improper load positioning
- Terrain instability
What to do
Reduce the load or reposition it to within safe limits. Ensure the V519 is on stable ground. If the warning persists, inspect load moment sensors.
Engine Oil Pressure Loss
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter or passages
What to do
Stop the engine immediately. Check oil level and add if low. Do not restart until the cause is diagnosed and repaired to avoid engine damage.
Brake System Malfunction
Common causes
- Low brake fluid
- Worn brake pads
- Hydraulic leak in brake circuit
What to do
Park the V519 on level ground and engage parking brake. Check brake fluid reservoir and inspect for leaks. Have the brakes serviced before further operation.
Frequently Asked Questions
What does the red 'Stop' light mean on my Bobcat V519?
It indicates a critical fault that requires immediate engine shutdown to prevent damage. Check other warning lights and consult the manual or dealer.
Can I operate the V519 with the amber 'Check Engine' light on?
It's not recommended. The light signals a potential issue with emissions or performance. Continued use may cause further damage; schedule service soon.
Why does the DPF regeneration light come on frequently on my V519?
Frequent regen needs may indicate excessive idling or low-load operation. Ensure the machine works under sufficient load to burn soot. If persists, check exhaust system.
How do I reset the service hour meter on the V519?
The hour meter is a reminder and cannot be reset manually. After performing scheduled maintenance, the dealer can reset it via diagnostic tool.
What should I do if the overload warning light appears while lifting?
Stop lifting immediately and lower the load. Reposition to reduce load moment or remove excess weight. Never bypass the overload system.
Is it normal for the transmission temperature light to come on after heavy use?
It can be normal under prolonged heavy load, but if it stays on, reduce load and let the transmission cool. Check fluid level and condition if it recurs.
