Caterpillar NO20S Order Picker Operator Manual (WHOMM0021)

The Cat NO20S is an electric order picker for case picking from an elevated operator platform in warehouse aisles. This manual is for the person learning to operate, inspect, charge, and safely maintain the truck. If your weekend job is getting an unfamiliar NO20S back into safe daily use, this is the right starting book. For workshop-level component repair, use the companion chassis service manual, also available.

What this manual helps you do

• Inspect the operator platform, lift chains, mast, gates, and safety interlocks before use.
• Follow the correct procedures for driving, lifting, lowering, parking, and battery charging.
• Check battery condition, controls, warning indicators, and basic truck maintenance points.
• Verify safety devices and operating functions before returning the truck to service.
• Troubleshoot basic alarm or operating symptoms using the truck's instructions.

Who this is for

This suits a warehouse maintenance technician, plant maintenance lead, rental fleet mechanic, or operator who needs to learn the truck without relying on tribal knowledge. It is an operator and daily-maintenance manual, while the companion chassis service manual covers deeper electrical, hydraulic, mast, and drive repairs.
