Scissor Lift Won't Start - Basic Troubleshooting

Step 1: Check Emergency Stop Button

Problem: Emergency stop is engaged
Solution:

• Locate the red emergency stop button (usually on control panel)
• Twist clockwise to release
• Attempt to start again

If this resolves the issue: Explain to customer this is a safety feature and how to avoid in future.

Step 2: Verify Battery Connection

Problem: Loose or corroded battery terminals
Solution:

• Ask customer to visually inspect battery terminals
• Look for loose connections or white/green corrosion
• If safe to do so, tighten connections or clean terminals
• DO NOT ask customer to touch battery if they're uncomfortable

Safety Note: Only suggest this if customer is comfortable. Otherwise, proceed to Step 6.

Step 3: Check Battery Charge Level

Problem: Depleted battery
Solution:

• Check battery gauge/indicator
• If below 20%, battery needs charging
• Locate on-board charger connection point
• Plug into appropriate power source (110V or 240V as specified)
• Allow minimum 2 hours charging for partial charge

Charging Safety:

• Ensure power source matches equipment specifications
• Keep area well-ventilated during charging
• Do not operate while charging

Step 4: Inspect Key Switch

Problem: Faulty key switch or wrong key position
Solution:

• Ensure key is fully inserted
• Try removing and reinserting key
• Check key switch for damage
• Verify key corresponds to this unit

Step 5: Check Platform/Ground Controls

Problem: Wrong control station selected
Solution:

• Many scissor lifts have dual controls (platform + ground)
• Check if there's a selector switch
• Ensure correct control station is selected
• Try both control panels if applicable

Step 6: Verify Tilt Sensor/Level Safety

Problem: Equipment on uneven surface triggering safety lockout
Solution:

• Scissor lifts have tilt sensors preventing operation on slopes
• Ask customer to check if equipment is on level ground
• If on a slope, equipment must be relocated to level surface
• Use spirit level if available

Step 1: Emergency Stop Check

Same as electric models (see above)

Step 2: Fuel Level Verification

Problem: Empty fuel tank or fuel shutoff engaged
Solution:

• Check fuel gauge
• Verify fuel shutoff valve is in "ON" position
• If empty, arrange fuel delivery or advise customer on refueling

Step 3: Glow Plug Cycle (Diesel Only)

Problem: Engine not pre-heated sufficiently
Solution:

• Turn key to "ON" position (not start)
• Wait for glow plug indicator light to extinguish (15-30 seconds)
• Then turn to "START" position
• Do not crank for more than 10 seconds at a time

Step 4: Battery Check

Follow same process as electric models (Steps 2-3 above)

Step 5: Air Filter Inspection

Problem: Clogged air filter restricting airflow
Solution:

• Locate air filter housing
• Visual inspection for excessive dirt/debris
• If heavily soiled, may require service call
• Document condition for technician
