Nissan N01 Series Forklift Service Manual & Technical Bulletin – 3-Wheel Electric PDF

Description

Nissan N01 Series Forklift Service Manual & Technical Bulletin

The Nissan N01 Series Forklift Service Manual & Technical Bulletin is the complete factory-issued workshop documentation for the N01, GN01, and SN01 three-wheel electric forklift series, published as a single PDF. It combines the full eleven-section service manual — General Information, Maintenance, Drive Control System, Front Axle, Rear Axle, Brake System, Steering System, Hydraulic System, Loading Mechanism, Body & Frame, and Body Electrical — with every relevant technical bulletin Nissan issued for the series up to May 2002, plus the later Controller Section that documents the Sevcon SC2542 and SEM traction controller systems. In other words, this is not just a maintenance booklet — it is the whole workshop reference for anyone who has to service, diagnose, adjust, or rebuild an N01-series electric forklift.

What the Document Gives a Technician

Each section of this Nissan N01-series service manual follows the same working pattern: a precaution page that tells you what to disconnect, isolate, or block before touching the system, a service-data and specifications table giving the standard value, limit value, and tightening torque for the procedure you are about to perform, then the removal, disassembly, inspection, assembly, installation, and adjustment steps written out procedurally. Diagrams sit alongside the procedures — exploded views of assemblies, circuit schematics, wiring harness layouts, hydraulic piping diagrams, mast and carriage illustrations, and dimensional charts. Nothing is left as a general description; every adjustment procedure gives a measurable target, whether that is brush spring pressure in newtons, commutator diameter limits, turning torque of the axle hub, chain deflection, pad clearance, or main relief valve pressure.

The chapters are grouped by system so a job can be worked through end to end without jumping around. If you are replacing a traction motor, the DC section walks through brush checks with a spring balance, commutator inspection with No. 500 or No. 600 sandpaper, insulation resistance with a 500 V megger, matching marks for disassembly, and the puller procedure for driving the front side bracket out. If you are resealing a lift cylinder, the HD section starts with pressure relief through the control lever, covers cylinder head torque, piston ring, V-ring, wiper ring, and O-ring replacement, and finishes with bleeding and height adjustment. If you are tracking down a steering fault, ST gives you a set of numbered symptoms — hard steering, locked wheel, PS relay cutting out, PS motor overheating, steering wheel steering by itself — each with its own test sequence measured at specific test points on the power steering controller.

Technical Bulletins Included

The technical bulletin content inside this PDF is worth noting separately because it fills in what the base manual could not have known at first publication. The September 1996 notice adds the high-performance GN01L16U and GN01L18U models and lists what changed on the GN01 — larger chassis dimensions, transistor chopper controller with field weakening, twin steering wheels, roller-type steering angle sensor replacing steering angle switches, and the front axle hub nut bolted directly to the axle hub. The hydraulic system bulletin from September 2000 introduces the outside-pulley type 2W mast and the revised lift cylinder, along with its own torque tables and air-bleeding procedure. The May 2002 controller section covers the newer SEM traction controllers and series pump controller, the CANbus communication between them, the CAN calibrator tree structure, and the full diagnostic list including P and F fault codes and their flow charts. Two further bulletins cover the neutral brake setting for the SEM controller and the controller personality values that must be set when a traction controller is replaced.

That layering matters if you own an early N01 truck as well as a later GN01 or an HP model — the book covers both ends of the production run without you needing to hunt for separate supplements.

Models Referenced Throughout

The specification tables and identification pages list the following model codes across the European and North American ranges: SN01L13HQ, N01L15HQV, N01L18HQV, GN01L16HQ, GN01L18HQ, N01L15HV, N01L18HV, N01L13U, N01L15U, N01L18U, GN01L16U, and GN01L18U. Chassis serial numbers follow the N01-XXXXXX, GN01-XXXXXX, and SN01-XXXXXX formats. Capacity variants include 1.25 ton, 1.5 ton, 1.6 ton, and 1.75 ton, with load centres of 500 mm and North American ratings listed in pounds.

Systems and Subsystems Covered in Detail

The drive control section is the heaviest part of the drive electronics side of the manual, running from the freewheel diode and commutation condenser inspections through to the plugging diode, blocking diode, thyristor thermal switch test using an iron plate in hot water, and the entire diagnostics tree with short form diagnostic lists for both main and harness codes. The hydraulics side runs from the oil pump motor brush and commutator checks through the pump disassembly with marked bush locations, seal replacement, and running-in procedure, into the control valve with relief valve pressure adjustment, tilt cylinder resealing, lift cylinder inner valve rebuild, oil and filter changes, and hydraulic hose replacement line by line. Body electrical covers the battery itself — specific gravity tables, temperature conversions, freezing point data, charging precautions — plus fuse block, fusible link, headlamp, turn signal, rear combination lamp, stop lamp switch, hour meter, and battery capacity meter.

Who This Manual Suits

This Nissan N01-series service manual and technical bulletin set suits forklift technicians, workshops running mixed electric fleets, and owner-operators who service their own N01 or GN01 truck in-house. The procedures assume access to standard garage tooling plus a handful of special items the manual identifies by number, such as the pressure gauge for hydraulic relief testing and the flare nut torque wrench for brake piping. Every torque figure in the book is printed in three units — N·m, kg-m, and ft-lb — so no conversion is needed whichever system you work in.

With this Nissan N01 Series Forklift Service Manual & Technical Bulletin on hand you can carry out the full range of scheduled maintenance, diagnose and repair drive control and controller faults using the numbered fault flow charts, rebuild the hydraulic pump, control valve, tilt and lift cylinders, adjust the mast rollers, back-up metals, and lift chains to the printed clearances, service the front and rear axle assemblies, overhaul the brake master cylinder and disc brakes, and set up a replacement traction controller with the correct model-specific personality values. Every one of those jobs depends on having the exact standard value, service limit, and tightening torque in front of you — guesswork on a forklift’s brake or hydraulic system is a shortcut to a comeback repair or worse.
