It is essential that care be exercised in the
purchase and application of lubricants.
The application of the right lubricant in the
right place at the right time and by the right
method will greatly reduce the actual cost of
transportation delivered.
THE RIGHT LUBRICANT
In your selection of the proper brand of oil,
it is desirable to consider the reputation of the
refiner or marketer. He is responsible for the
quality of his product and his reputation is the
vehicle owner's best indication of quality.
THE RIGHT PLACE
Lubrication fittings or accessible lubrication
points have been incorporated on all mechanical
units of the vehicle, where lubrication is needed.
THE RIGHT TIME
Intervals at which various points on the chassis
should receive attention are indicated on the lub-
rication chart. Intervals are based upon actual
experience and tests, as well as careful consider-
ation of design and purpose of parts to be lub-
ricated.
THE RIGHT METHOD
The correct application of the lubricant to the
various points is essential. Procedures specifi-
cally applying to the process of lubricating various
units are outlined in the explanatory notes.
When necessary to remove a unit in order to
accomplish lubrication, procedures necessary for
such removal are shown in applicable sections of
the manual.
