Daily Maintenance Items for Electric Aerial Work Platforms

I. Pre-operation Daily Inspection (Mandatory)

Appearance & Structure

• Inspect the boom, outriggers, tires, pins and welds for deformation or cracks.
• Ensure guardrails, pedals and emergency stop buttons are intact.
• Check for signs of oil leakage, water leakage or electric leakage.

Battery & Electrical System

• Ensure battery power and voltage are normal.
• Inspect charging ports and wiring harnesses for damage or looseness.
• Confirm no fault codes on the dashboard and all indicator lights function properly.
• Verify that the horn, lights and alarm devices work normally.

Hydraulic System

• Check hydraulic oil level is normal with no leakage.
• Inspect oil pipes and connectors for aging or crushing damage.
• Ensure lifting and luffing movements are free of abnormal noise or shaking.

Travel & Braking System

• Check tire pressure and wear condition.
• Ensure drive wheels and steering are flexible with no abnormal noise.
• Verify parking brake and service brake are effective.

Safety Devices

• Ensure tilt alarm, overload alarm and limit switches function normally.
• Confirm emergency stop buttons on upper and lower controls are effective.
• Check that outriggers extend, retract and lock properly.

II. Post-operation Daily Maintenance

• Clean mud, sand, gravel and debris from the platform, chassis and boom.
• Park the machine on level ground, retract outriggers and lower the boom completely.
• Check battery power; recharge promptly if below 30%.
• Wipe the control panel and check for spilled liquids.
• Record abnormal noise, shaking or malfunctions and report for repair immediately.

III. Weekly Maintenance Items

• Lubricate pins, joints, chains and pulleys with grease.
• Inspect battery terminals, clean oxides and tighten connections.
• Check hydraulic oil filter and oil quality; replace if necessary.
• Test all safety devices: limit switches, tilt protection, emergency stops, overload protection.
• Inspect brake wear and drive belt tension.

IV. Monthly Maintenance Items

• Check battery electrolyte (lead-acid) or battery health status (lithium-ion).
• Tighten key bolts throughout the machine: outriggers, slewing bearing, chassis connections.
• Inspect hydraulic system pressure and adjust to standard values.
• Clean motor vents and electrical box dust screens.
• Check cables and hoses for wear; avoid crushing or abrasion.

V. Long-term Storage Maintenance

• Fully charge the battery before storage; recharge every 15 days.
• Support outriggers with wooden blocks to prevent long-term pressure on tires.
• Disconnect main power supply and cover with a protective tarp.
• Avoid exposure to direct sunlight, rain or flooding.

VI. Special Notes (Key for Electric Models)

• Do not drive through water; electrical boxes and motors must not be submerged.
• Use only the original charger; mixing chargers is prohibited.
• Stop operation immediately if abnormal noise, shaking, oil leakage or electric leakage occurs.
• Overloading, exceeding the rated elevation angle and unauthorized personnel riding are strictly prohibited.
