Caterpillar DP25NM Forklift Service Manual (99729-80100)

If your Cat DP25NM is moving pallets around a warehouse, plant, or yard, this is the workshop manual for that diesel counterbalanced truck. I've used this kind of book when a tech needs to diagnose a fault, set up a system, or tear into a truck instead of guessing. For a DP25NM with serial AT18D-00012-49999, the answer is yes.

What this manual helps you do

• Trace electrical faults through wiring, switches, and truck circuits.
• Check and adjust brakes, steering, hydraulics, mast, and forks.
• Diagnose power train and powershift transmission problems.
• Follow removal, inspection, repair, and installation procedures for truck components.
• Troubleshoot operating faults using service data and adjustment guidance.

Who this is for

This suits warehouse maintenance technicians, plant maintenance crews, rental fleet mechanics, dealer technicians, and independent forklift repair shops. It fits the forklift repair trade, with the operator handbook and parts catalog available as companion volumes. Engine internals are handled in the companion engine service manual, also available.
