Clark HWXE, PWXE 30-40 Pallet Truck Service Manual (SM748)

These HWXE and PWXE 30–40 pallet trucks spend their lives shuttling pallets in warehouses, loading docks, and tight backroom spaces, so when they quit lifting or creeping under load, you need to get them sorted fast. This service manual helps you trace faults, strip components in the right order, and put everything back together so the truck tracks straight and lifts reliably again. For example, if the forks won’t raise or drift down, this is what you’d use to isolate whether you’ve got a hydraulic issue, a control linkage problem, or a worn seal before you start throwing parts at it.

Applications & Use Cases

• Track down hydraulic faults when lift is slow, jerky, or won’t hold a load, and verify what to test first.
• Plan periodic service so you don’t miss key inspection points on steering, brakes, and mast hardware.
• Follow disassembly/assembly sequences to avoid bending linkages or damaging seals during cylinder or pump work.
• Check and adjust controls so the handle, lift, and lower functions operate smoothly and predictably.
• Support shop training, giving newer techs a clear workflow to diagnose instead of just replacing parts.

FAQ

Q: Can I use this manual on a tablet in the shop?

A: Yes, it works well digitally; you can zoom diagrams and use search to jump to the system you’re working on.

Q: Is it worth printing sections of this manual?

A: Many techs print just the procedures they’re doing that day, so they can mark notes and keep it next to the truck.

Safety Note

Always secure the pallet truck and relieve stored energy before you get under, around, or into any lifting components.
