INTRODUCTION
This service manual has been prepared to provide necessary information concerning the maintenance and repair
procedures for the NISSAN FORKLIFT 1B1 and 1B2 series for pneumatic and cushion model.
Any changes effected in the series after publication of this service manual will be announced in a technical bulletin.
It is, therefore, recommended that each relevant technical bulletin be inserted in front of each section and be used
together with the service manual as a reference.
If a new model requires different service method or has undergone a major change, revised sections will be issued
to replace the applicable sections. Each revised section will include the description of how to service the parts for
the former specifications. The publication of a revised section will be announced in the technical bulletin.
This service manual consists of fourteen sections as shown in the following table, which gives the updated symbols.
When a revised service manual is issued, this “INTRODUCTION” sheet should be replaced with a revised one.

This manual contains maintenance and repair procedures.
In order to assure your safety and the efficient functioning of the lift truck, this manual should be read
thoroughly. It is especially important that the PRECAUTIONS in the GI section be completely
understood before starting any repair task.
All information in this manual is based on the latest product information at the time of publication.
The right is reserved to make changes in specifications and methods at any time without notice.
IMPORTANT SAFETY NOTICE
The proper performance of service is essential for both the safety of the technician and the efficient
functioning of the lift truck.
The service methods in this Service Manual are described in such a manner that the service may be
performed safely and accurately.
Service varies with the procedures used, the skills of the technician and the tools and parts available.
Accordingly, anyone using service procedures, tools or parts which are not specifically recommended
by NISSAN must first be completely satisfied that neither personal safety nor the lift truck's safety will
be jeopardized by the service method selected.
No modifications or alterations to a powered industrial truck, which may affect, for example, capacity,
stability or safety requirements of the truck shall be made without the prior written approval of
NISSAN, its authorized representative, or a successor thereof. Contact an authorized NISSAN
FORKLIFT dealer before making any modification or alteration to your industrial truck that may affect,
for example braking, steering, visibility and the addition of removable attachments. After getting
approval of NISSAN, its authorized representative, or a successor thereof, capacity plate, decals tags
and operation and maintenance handbooks shall also be changed to the appropriate one.
Only in the event that NISSAN is no longer in business and there is no successor in the interest to the
business, the user may arrange for a modification or alteration to a powered industrial truck, provided,
however, that the user shall:
A. Arrange for the modification or alteration to be designed, tested and implemented by an engineer(s)
expert in industrial trucks and their safety;
B. Maintain a permanent record of the design, test(s) and implementation of the modification or
alteration;
C. Approve and make appropriate changes to the capacity plate(s), decals, tags and Instruction
Handbook;
D. Affix a permanent and readily visible label to the truck stating the manner in which the truck has
been modified or altered together with the date of the modification or alteration, and the name and
address of the organization that accomplished the tasks.

PRECAUTIONS AND PREPARATION
PRECAUTIONS AND PREPARATION
Precautions
CAUTION:
• Be extremely careful when hoisting and moving heavy
objects. These can be extremely dangerous operations.
• Always clean working area to prevent foreign matter from
getting into parts being assembled or serviced.
• Use a paper rag rather than a cloth when wiping clean parts.
Use of a cloth rag may leave lint or other foreign matter on
parts being wiped.
NOTE:
• It is good practice to remove or install differential carrier together
with front axle assembly. This procedure makes it easier to work
on the differential carrier.
• Before removing differential carrier, it is advisable to clean front
axle assembly and differential carrier.
• Removal and installation of some differential carrier parts requires
use of special service tools as indicated in the table below.
