The Bobcat Telehandler 753 instrument cluster uses color-coded warning lights to alert operators to machine status and potential issues. Understanding these indicators is essential for safe operation and preventing damage. This guide explains each symbol and the appropriate response.
Bobcat Telehandler 753 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical fault has occurred, such as low engine oil pressure or high coolant temperature, that demands immediate engine shutdown on your Bobcat 753. | Stop the engine and investigate the associated warning light or gauge. | |
| Master Caution | AMBER | A non-critical system fault requires attention, like an air filter restriction or hydraulic oil temperature warning on the 753. | Refer to the secondary warning lights and service the system soon. | |
| Check Engine (MIL) | AMBER | The engine management system has detected a fault, such as a sensor issue or emission system problem unique to your Bobcat 753's diesel engine. | Have the engine diagnosed and repaired by a qualified technician. | |
| Engine Oil Pressure | RED | Oil pressure is below safe level, risking engine damage on your Bobcat 753 telehandler. | Immediately stop the engine and check oil level and for leaks. | |
| Battery / Charging | RED | The charging system is not functioning, possibly due to a failed alternator or loose belt on the Bobcat 753. | Check alternator belt tension and battery connections; service if needed. | |
| Coolant Temperature | RED | Engine coolant is overheating, which can cause severe damage in your Bobcat 753 if not addressed. | Stop the engine and allow it to cool; check coolant level and radiator for blockages. | |
| Hydraulic Oil | AMBER | Hydraulic oil temperature is high or level is low, affecting the performance of the Bobcat 753's lift and tilt functions. | Let the hydraulics cool and check oil level; look for leaks. | |
| Parking Brake | RED | The parking brake is engaged or a fault in the brake system is present on your Bobcat 753. | Release the parking brake before moving if indicator stays on, inspect brake system. | |
| Glow Plug / Preheat | AMBER | The glow plugs are active for cold starting; wait until it turns off before cranking your Bobcat 753. | Wait for the light to go out before starting the engine. | |
| Low Fuel | AMBER | Fuel level is low; refuel soon to avoid running out during operation of your Bobcat 753. | Add diesel fuel to the tank. | |
| High Beam | BLUE | High beam headlights are on, improving visibility for night or low-light operation of your Bobcat 753. | No action needed; switch to low beam when approaching others. | |
| Work Lights | GREEN | The auxiliary work lights are illuminated, providing additional lighting for the Bobcat 753's work area. | No action needed; turn off when not required to save battery. | |
| Overload / Capacity | RED | The load on the telehandler exceeds the rated capacity, risking tip-over or structural failure on this Bobcat 753. | Immediately reduce the load or reposition to stay within limits. | |
| Mast / Lift Limit | AMBER | The mast has reached the maximum height or load limit for the current configuration of your Bobcat 753. | Lower the load or adjust position to stay within safe operating range. | |
| Water in Fuel | AMBER | Water has been detected in the fuel system, which can cause injector damage in your Bobcat 753. | Drain the water separator or fuel filter as soon as possible. | |
| Air Filter | AMBER | The engine air filter is restricted, reducing engine performance and fuel economy on your Bobcat 753. | Clean or replace the air filter element. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Clogged radiator fins with debris
- Failed cooling fan or thermostat
What to do
Stop the Bobcat 753 immediately and let the engine cool. Check coolant level and radiator cleanliness; top off coolant and clean fins. If persistent, inspect thermostat and fan operation.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Contaminated or degraded hydraulic fluid
- Leaking hose or fitting
What to do
Check hydraulic oil level and top up with recommended fluid for your Bobcat 753. Inspect hoses and fittings for leaks and repair as needed. Replace fluid if contaminated.
Brake System Malfunction
Common causes
- Worn brake pads or shoes
- Low brake fluid level
- Air in brake lines
What to do
Check brake fluid level and top up; bleed brakes if air is present. Inspect and replace worn brake components on your Bobcat 753.
Overload Condition
Common causes
- Exceeding rated lift capacity
- Unbalanced or shifting load
- Operating on uneven terrain with heavy load
What to do
Reduce load to within rated capacity for your Bobcat 753. Ensure load is stable and centered; reposition on level ground before lifting.
Engine Electrical Fault
Common causes
- Loose or corroded battery terminals
- Failed alternator
- Blown fuse or bad relay
What to do
Clean and tighten battery connections. Test alternator output; replace if not charging. Check and replace blown fuses or relays in the Bobcat 753's electrical system.
Frequently Asked Questions
Why does the master warning light come on and the engine shuts down?
The master warning indicates a critical fault like low oil pressure or high coolant temperature. On the Bobcat 753, this triggers an automatic shutdown to prevent engine damage. Check the associated gauge and address the underlying issue before restarting.
What should I do if the hydraulic oil warning light flashes?
This amber light signals high temperature or low level. Stop lifting operations and let the hydraulic system cool. Check the sight glass for oil level and add hydraulic fluid if needed on your Bobcat 753.
Can I operate the telehandler with the check engine light on?
It is not recommended. The check engine light on the Bobcat 753 indicates a fault that may reduce performance or damage the engine. Have the diagnostic code read and repaired promptly.
How do I know if my Bobcat 753 is overloaded?
The overload warning light (red) will illuminate and may be accompanied by an audible alarm. Immediately lower the load and reposition to stay within the rated capacity shown on the load chart.
What does the glow plug light mean during startup?
The amber glow plug light indicates the preheat cycle is active. On the Bobcat 753, wait for it to turn off (typically 3-8 seconds) before cranking the engine for reliable cold starts.
Why is the air filter light on even after cleaning the filter?
The light may be triggered by a clogged filter that hasn't been fully cleaned or a faulty sensor. On the Bobcat 753, replace the air filter element if cleaning doesn't resolve it, and check the restriction indicator.
