Yale forklifts are equipped with various warning lights to ensure safe operation and prompt maintenance. Understanding these symbols is crucial for operators to respond appropriately to potential issues. Let's explore the most common Yale forklift warning light symbols and their meanings.

Engine-related warning lights

Oil pressure alert

The oil pressure alert light typically resembles an oil can. When illuminated, it indicates low engine oil pressure. If this light stays on after starting the engine, stop operations immediately and check the oil level.

Engine fault indicator

An engine-shaped symbol or "CHECK ENGINE" light signifies a potential engine malfunction. This could range from minor issues to serious problems requiring immediate attention. Consult the error code display for more specific information.

Coolant temperature warning

A thermometer symbol or wavy lines indicate high engine coolant temperature. If this light comes on, safely park the forklift and allow the engine to cool down before investigating the cause.

Transmission and brake warnings

Transmission oil temperature

A gear symbol with a thermometer warns of high transmission oil temperature. Continued operation could lead to transmission damage. Allow the forklift to idle or shut it down to cool the transmission fluid.

Parking brake indicator

A "P" symbol or brake icon indicates that the parking brake is engaged. Ensure this light is on when parking and off before attempting to drive.

Battery and electrical system

Battery charge indicator

A battery symbol illuminates when the charging system is not functioning correctly. If this light stays on while the engine is running, the alternator may not be charging the battery properly.

Safety-related indicators

Seat belt reminder

A seat belt icon reminds the operator to fasten their seat belt. Some models may prevent operation if the seat belt is not fastened.

Operator presence system

An operator symbol or seat icon may light up if the operator leaves the seat without engaging the parking brake, indicating a potential safety hazard.

Fuel and emissions

Fuel level indicator

A fuel pump symbol or low fuel light warns when fuel levels are critically low. Refuel promptly to avoid running out of fuel during operation.

Diesel exhaust fluid (DEF) warning

For diesel models, a DEF symbol indicates low diesel exhaust fluid levels. Refill DEF to maintain emissions compliance and prevent reduced engine performance.

Maintenance reminders

Service due indicator

A wrench symbol or "SERVICE" light indicates that scheduled maintenance is due. Consult your maintenance schedule and arrange for service promptly.

Air filter indicator

An air filter symbol suggests that the air filter needs cleaning or replacement. Address this promptly to maintain engine efficiency and prevent damage.

Hydraulic system warnings

Hydraulic oil temperature

A hydraulic symbol with a thermometer indicates high hydraulic oil temperature. Cease operations and allow the system to cool to prevent damage to hydraulic components.

Hydraulic filter restriction

A clogged filter symbol suggests that the hydraulic filter is restricted and needs replacement. Failure to address this can lead to hydraulic system damage.
