Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low engine oil level
- Oil pump failure
- Oil filter blockage
What to do
Immediately stop the E20, check oil level and refill if low; if the problem persists, have the oil pump and filter inspected by a Bobcat technician.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Failed thermostat
What to do
Turn off the E20 and allow it to cool; inspect coolant level and radiator for obstructions, and seek professional service if overheating continues.
Hydraulic System
Common causes
- Low hydraulic fluid
- Hydraulic hose leak
- Clogged hydraulic filter
What to do
Check the E20's hydraulic fluid reservoir, refill if needed, and inspect for visible leaks or damaged hoses; replace the filter if necessary.
Battery / Charging
Common causes
- Broken alternator belt
- Faulty alternator
- Corroded battery terminals
What to do
Inspect the alternator belt for damage, clean battery terminals, and have the charging system tested at a Bobcat service center.
DPF / Regeneration
Common causes
- Excessive soot in DPF
- Interrupted regeneration cycles
- DEF system malfunction
What to do
Follow the E20’s display prompts to complete a regeneration cycle; if the light remains, check DEF fluid and consult a Bobcat dealer.
Frequently Asked Questions
What should I do if the DPF regeneration light stays on?
Keep the E20 running at a high idle to allow the regeneration cycle to finish; if the light does not go out, contact your Bobcat dealer.
Why is the hydraulic oil light illuminated?
This means the hydraulic oil level is low or the oil is contaminated; top up the oil and check for leaks or dirty fluid.
Can I operate the E20 if the fuel filter light is on?
Operation is not recommended; drain the water separator and replace the fuel filter promptly to avoid engine issues.
How do I reset the service/hour meter indicator?
After performing scheduled maintenance, follow the E20 operator's manual instructions to reset the hour meter through the display menu.
Is it safe to run the E20 with the master caution light on?
You may continue operating briefly, but investigate the cause as soon as possible to prevent further issues.
