Caterpillar EP15TCB Forklift Service and Operator Manual (99759-6T110)

This Cat EP15TCB is an electric counterbalanced forklift for moving pallet loads around a warehouse, plant, or yard. In my experience, a warehouse maintenance tech or dealer mechanic reaches for this manual when a truck needs fault diagnosis, adjustment, or repair by the book. It gives the workshop procedures needed to return the lift to service and keep maintenance records audit-ready.

What this manual helps you do

• Trace electrical faults through wiring, switches, motors, and controller circuits.
• Diagnose alarm codes and verify controller parameters during service work.
• Check and adjust the brake, steering, hydraulic, mast, and fork systems.
• Follow procedures for traction motor, drive unit, transmission, and axle repairs.
• Set service intervals and verify repairs against the listed specifications and test procedures.

Who this is for

This suits warehouse maintenance technicians, plant maintenance staff, dealer technicians, independent forklift repair shops, and rental fleet mechanics working on Cat electric trucks. The companion chassis manual is also available for technicians who need the broader counterbalanced-truck reference.
