Warning
The repair works of the vehicle are dangerous. The repair personnel not receiving the related vehicle
repair training will probably cause repair failure or even loss of properties and personal injuries. Only the
technical personnel receiving the related vehicle repair training and having actual repair experiences are
allowed for repair works.
The repair procedures contained in this manual, including parts “Warning” and “Caution”, are prepared
by technical training personnel of Haima Automobile Co., Ltd. Before the repair operations, the repair
personnel shall carefully read this manual to understand general safety procedures. The technical personnel
shall abide by the “Warnings” and “Cautions” to reduce the injury hazard and the possibility of vehicle
damage and potential safety problems arising from the improper repairs and services. It’s of equal importance
that it should be understood that the “Warnings” and “Cautions” do not include everything and are impossible
to warn all hazardous consequences arising from the violations of the operation procedures.
The repair recommendations and related procedures contained in this manual are the effective service
and repair methods. Some repair operations require the use of special tools. The personnel using the
procedures or tools not recommended by Haima Automobile must take cautions to guarantee the safety of
personnel and vehicle.
The genuine Haima Automobile parts or the parts designated by Haima Automobile shall be used during
replacement of parts. Haima Automobile will not be liable for any problem arising from the following factors:
Insufficient training, improper use of tools, use of non-genuine Haima Automobile parts or parts other than
those designated by Haima Automobile, and the negligence of revisions to this manual. The factors are not
limited to the above mentioned ones.
