Description

EP FT/FTH Series CPD15-CPD35 Electric Forklift Manual

The EP FT/FTH Series CPD15/18/20/25/30/35 Electric Forklift Operation, Maintenance & Troubleshooting Manual – PDF is an English technical manual for EP four-wheel electric sit-down forklifts in the FT and FTH families. Although officially titled an Operation Manual, this 98-page document contains substantial maintenance and diagnostic information in addition to normal operating instructions.

The manual covers truck specifications, controls and displays, transport and commissioning, battery charging and maintenance, scheduled forklift servicing, lubrication, steering, brakes, hydraulics, lifting-system troubleshooting and detailed electrical fault diagnosis. Of particular value to technicians are the sections covering ZAPI DualAC2 / DualAC2&HP inverter diagnostics and ZAPI AC-2 inverter diagnostics, including controller alarms, fault codes and troubleshooting guidance.

EP FT/FTH Models Covered

• CPD15FT / CPD15FTH
• CPD18FT / CPD18FTH
• CPD20FT / CPD20FTH
• CPD25FT / CPD25FTH
• CPD30FT / CPD30FTH
• CPD35FT / CPD35FTH

The foreword identifies the manual as applicable to FT1.5-3.5 and FTH1.5-3.5 electric forklift trucks. The cover identifies the FT/FTH Series and CPD15/18/20/25/30/35 capacity range.

Truck Controls, Displays and Specifications

The opening chapters describe the truck assemblies, steering and instrument displays, combined light switch, key switch, emergency disconnect switch, travel switch, hydraulic control levers, pedals and other body components. Separate instrument and display information is provided for FT and FTH configurations.

The manual also includes truck identification points, data plates, standard-version specifications, performance data, dimensional information and guidance on the relationship between load and forklift stability.

Operation and Commissioning

Transport and commissioning procedures include crane lifting, securing the forklift during transport, towing, initial commissioning and the first 100-hour running-in period. The operating section then covers daily preparation, switching on the truck, travelling, steering, braking, load pickup and deposit, and checks after operation.

For the running-in period, the manual recommends avoiding sudden stops, starts and turns, carrying out preventive maintenance carefully, performing oil changes and lubrication earlier than normal where specified, and limiting loads to approximately 70-80% of rated capacity.

Battery Maintenance and Charging

A dedicated battery chapter covers safety precautions for acid batteries, battery types and dimensions, charging, first charging, daily charging, battery removal and installation, electrolyte level, distilled-water replenishment, specific-gravity readings and battery maintenance.

The charging information also includes equalising-charge procedures, opportunity charging and charging requirements during long-term storage. These sections provide practical guidance for maintaining the traction battery used in the covered electric forklifts.

Scheduled Forklift Maintenance

The maintenance section goes considerably beyond a basic operator handbook. It includes daily maintenance and periodic inspection requirements for the major truck systems, including:

• Storage battery
• Controller
• Motor
• Driving system
• Front and rear wheels
• Steering system
• Brake system
• Hydraulic system
• Lifting system
• Additional inspection items
• Periodic replacement of safety-related parts
• Bolt tightening-torque information
• Lubrication schedule
• Fuels, coolants and lubricants
• Short-term and long-term truck storage

Daily maintenance procedures address hydraulic oil, electrolyte and brake-fluid leakage, tyre condition and pressure, wheel-nut torque, brake-pedal operation, parking-brake operation, accelerator pedal, driver seat, battery condition and other routine checks.

Steering and Brake Troubleshooting

The troubleshooting chapter provides symptom, probable-cause and corrective-action tables for the steering and brake systems. Steering diagnosis includes oil leakage, excessive steering effort, inability to rotate the steering wheel, free play, wheel wobble and steering alignment issues.

Brake-system troubleshooting addresses insufficient brake force and brake dragging, with causes such as leaking brake lines, air in the system, contaminated or uneven brake linings, master-cylinder or wheel-cylinder faults, blocked oil lines, incorrect pedal free play, return-spring problems and wheel-bearing adjustment.

Hydraulic System Troubleshooting

The hydraulic section explains how high-pressure oil from the main pump is routed through the control valve to the lifting and tilting cylinders. It describes lifting, lowering and mast-tilting operation and then provides detailed troubleshooting for the main pump and hydraulic control valve.

Main-pump diagnosis covers no oil delivery, low discharge pressure, noisy pump operation, cavitation, air entering the suction side, incorrect oil viscosity, bubbles in the hydraulic oil and pump leakage. The control-valve troubleshooting tables cover unstable relief pressure, tilt-lock valve problems, mast drift, spool-valve return faults and external leakage.

The manual also includes a procedure describing adjustment of main relief-valve pressure and a separate troubleshooting section for the lifting system, including mast drift, sluggish carriage movement, uneven lifting and lubrication or adjustment problems.

ZAPI DualAC2 / DualAC2&HP Electrical Diagnostics

One of the most valuable technical sections is the inverter diagnostic information for the DualAC2 and DualAC2&HP controller system. The manual provides controller fault-code tables and detailed explanations of traction and pump alarms.

Diagnostic coverage includes faults such as:

• WATCH DOG
• LOGIC FAILURE #1 / #2 / #3
• VMN LOW / VMN HIGH
• STBY I HIGH
• CAP CHARGE
• DRIVER SHORTED
• CONTACTOR DRIVER
• COIL SHORTED
• CONTACTOR CLOSED / OPEN
• ENCODER ERROR
• PEDAL WIRE KO
• WRONG SET BATTERY
• PUMP KO
• MASTER KO
• INPUT MISMATCH
• HIGH TEMPERATURE
• MOTOR TEMPERATURE
• BATTERY LOW
• VACC NOT OK
• INCORRECT START
• FORW + BACK
• CAN communication and pump-controller faults

For many alarms, the manual goes beyond simply listing the code and describes possible wiring, encoder, contactor, potentiometer, controller, CAN-BUS or logic-board causes.

ZAPI AC-2 Inverter Diagnostics

The FTH electrical diagnostic material includes an AC-2 Inverter Diagnostic – Traction Configuration section. Alarm groups can be identified through diagnostic LED blink patterns, with categories covering logic failures, start-sequence and encoder problems, capacitor or phase-voltage faults, accelerator faults, current-sensor faults, contactor-driver faults, excessive temperature, CAN-BUS or safety-circuit faults and battery-voltage conditions.

The following pages analyse individual console alarms and provide possible causes and corrective guidance. This makes the manual especially useful when diagnosing electrical and controller problems on an FT/FTH forklift equipped with the corresponding ZAPI control system.
