This manual is designed primarily for use by
trained mechanics in a properly equipped shop.
However, it contains enough detail and basic information
to make it useful to the owner who desires
to perform his own basic maintenance and
repair work. A basic knowledge of mechanics,
the proper use of tools, and workshop procedures
must be understood in order to carry out
maintenance and repair satisfactorily. Whenever
the owner has insufficient experience or
doubts his ability to do the work, all adjustments,
maintenance, and repair should be carried
out only by qualified mechanics.
