Most Important Warning Lights

Engine Overheating

Common causes

  • Low coolant level
  • Clogged radiator grill
  • Faulty water pump or thermostat

What to do

Immediately stop the S130 and let the engine cool. Check coolant level and radiator cleanliness. Top off coolant if low, and clean debris from the radiator screen. If persistent, have the cooling system inspected by a Bobcat dealer.

Low Engine Oil Pressure

Common causes

  • Low oil level
  • Oil pump failure
  • Clogged oil filter
  • Diluted or degraded oil

What to do

Shut down the S130 engine right away. Check the oil dipstick and add oil if low. If light stays on, do not restart; have the oil system diagnosed by a technician.

Electrical Charging Failure

Common causes

  • Loose or broken alternator belt
  • Faulty alternator
  • Blown fuse or bad wiring

What to do

Inspect the alternator belt on your S130 for tension and wear. Check electrical connections. If the light remains after tightening or replacing the belt, service the charging system.

Hydraulic System Overheating

Common causes

  • Low hydraulic fluid
  • Excessive load
  • Blocked hydraulic cooler
  • Operating outside temperature limits

What to do

Reduce load and allow the hydraulic system to cool. Check hydraulic fluid level and add if needed. Clean the hydraulic cooler fins. Avoid prolonged heavy operation at high temperatures.

Fuel System Contamination (Water in Fuel)

Common causes

  • Water in diesel fuel from storage or condensation
  • Damaged fuel cap seal
  • Malfunctioning fuel separator

What to do

Drain the water separator bowl on the S130 immediately. If light recurs, replace the fuel filter and ensure you use clean fuel from a reputable source.

Frequently Asked Questions

Why is my Bobcat S130 glow plug light flashing?

A flashing glow plug light on the S130 indicates a fault in the preheat system, such as a bad glow plug or relay. Have it checked by a dealer to ensure reliable cold starts.

What does the air filter warning light mean on my S130?

It means the engine air filter is restricted and needs service. Replace or clean the filter to restore airflow and prevent power loss.

How do I reset the service hour meter on the S130?

The service light is not user-resettable; it clears after the required maintenance is performed by a dealer or if a code is entered. Refer to the manual or dealer.

Can I drive the S130 with the brake system light on?

No. If the brake system light is red, it means a serious fault. Stop and inspect brake fluid level and brakes. Driving could lead to brake failure.

Why does the PTO light stay on when I disengage it?

The light may remain on if the PTO switch is faulty or the control lever is not fully disengaged. Check the lever position; if still on, have the switch inspected.

What should I do if the master warning light comes on while operating?

Immediately bring the S130 to a safe stop and shut off the engine. Consult the operator's manual for the associated code and contact a Bobcat dealer for repair.
