The Skyjack aerial lift instrument cluster provides essential warnings and indicators to ensure safe operation and maintenance of your lift. Common models like the SJ3219 and SJ6826 RT feature a clear, easy-to-read display with color-coded alerts. Understanding these symbols helps prevent downtime and accidents.
Skyjack aerial lift Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Hydraulic System Warning | RED | Indicates a critical hydraulic system fault on your Skyjack lift, such as low fluid or a leak, which can affect lift and drive functions. | Immediately lower the platform, shut off engine, and inspect hydraulic fluid level and lines. | |
| Overload Warning | RED | This light activates when the platform load exceeds the rated capacity of the Skyjack model, triggering a warning alarm and disabling lift functions. | Remove excess weight from platform immediately and redistribute load evenly. | |
| Fasten Seat Belt | RED | On Skyjack lifts equipped with a seat belt sensor, this red light reminds the operator to secure the seat belt before operating the machine. | Fasten your seat belt before moving or elevating the platform. | |
| Service / Hour Meter | GREEN | The hour meter shows total operating hours; on Skyjack lifts, it also triggers a scheduled maintenance reminder at intervals like every 250 hours. | Refer to the Skyjack operator manual for service tasks due at the displayed hour count. | |
| Work Lights On | GREEN | Indicates the work lights are activated on your Skyjack lift for improved visibility in low-light conditions. | Work lights are on; turn off when not needed to conserve battery. | |
| Beacon / Rotating Light | AMBER | The amber beacon is illuminated when the Skyjack lift is in operation, warning nearby personnel of moving machinery. | Ensure beacon is visible and functional before driving; replace bulb if needed. | |
| Low Engine Oil Level | AMBER | On Skyjack diesel models like the SJ6832 RT, this amber light warns that engine oil level is low and needs topping up soon. | Check engine oil level with dipstick and add oil if below the add mark. | |
| Coolant Temperature High | RED | Indicates the engine coolant temperature has exceeded safe limits on your Skyjack aerial lift, risking overheating damage. | Stop engine immediately, allow to cool, and check coolant level and radiator for debris. | |
| Glow Plug / Preheat | AMBER | On Skyjack diesel lifts, this amber light shows that the glow plugs are preheating; wait until it turns off before starting the engine. | Turn key to 'on' position and wait for light to extinguish before cranking the engine. |

Most Important Warning Lights
Hydraulic System Failure
Common causes
- Low hydraulic fluid level
- Hydraulic hose rupture
- Contaminated fluid
- Pump failure
What to do
On Skyjack lifts, check hydraulic reservoir sight glass; if low, add approved Skyjack hydraulic oil (e.g., ISO 46). If leak is visible, secure platform and contact service.
Overload Condition
Common causes
- Exceeding platform capacity
- Uneven load distribution
- Side loading
- Wind load
What to do
On Skyjack lifts, the overload warning activates a buzzer and locks lift functions. Remove excess weight and redistribute load evenly on the platform.
Battery Discharge
Common causes
- Batteries not fully charged
- Faulty charger
- Shortened battery life
- Excessive accessory use
What to do
On Skyjack DC lifts, if BDI light is amber, return to charge point and plug in charger. If red, batteries may need replacement; check electrolyte levels.
Engine Overheating
Common causes
- Low coolant level
- Radiator blockage
- Thermostat failure
- Broken fan belt
What to do
On Skyjack diesel lifts, stop engine immediately. Allow to cool, then check coolant level in recovery tank. Clean radiator fins with compressed air.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
- Viscosity issues
What to do
On Skyjack lifts, stop engine immediately. Check oil level with dipstick; if low, add oil. If light persists, do not operate and call for service.
Frequently Asked Questions
What does the amber hydraulic light on my Skyjack SJ3219 mean?
It typically indicates low hydraulic oil level or a partial blockage. Check the sight glass on the hydraulic tank and top off with Skyjack-approved hydraulic oil if needed.
Why does my Skyjack lift alarm when I start moving?
That's the travel alarm, standard on most Skyjack lifts. It's a safety feature to warn nearby people. If it sounds continuously, the horn button might be stuck.
How do I reset the hour meter service reminder on a Skyjack?
You'll need the password from your Skyjack dealer. Usually, hold the hour meter reset button while turning key to on, then enter code via the joystick buttons.
What load capacity does a Skyjack SJ6826 RT have?
The SJ6826 RT has a maximum platform capacity of 1000 lb (454 kg) with standard platform and up to 800 lb (363 kg) with optional dual entry gates.
Can I drive my Skyjack lift with the overload light on?
No. The overload system will disable lift functions and drive may be limited. You must reduce the load to below rated capacity before resuming operation.
Why does my Skyjack lift have no power to the platform controls?
Check the emergency stop buttons (both at base and platform) are pulled out. Also verify the main battery disconnect switch is on. If still dead, check the 10-amp fuse near the batteries.
