Make sure the engine oil is at the specified level.
Add oil as necessary. (See pages 8-23–8-33.)CAUTION:_

In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do not
use oils with a diesel specification of “CD”
or oils of a higher quality than specified. In
addition, do not use oils labeled “ENERGY
CONSERVING II” or higher.


Make sure that no foreign material enters

Perform the Pre-Operation Checks on pages 5-1–
5-35. Set the parking brake, shift to neutral, and
follow the instructions on page 6-3 to start the en-
gine. Once it has warmed up and you have turned
the choke off, you are ready to begin driving your
vehicle. With the engine idling, shift the drive se-
lect lever into low or high. Then release the parking
brake. Press the accelerator pedal slowly and
smoothly. The centrifugal clutch will engage and
you will start to accelerate. Avoid higher speeds
until you are thoroughly familiar with the operation
of your vehicle.
When slowing down or stopping, take your foot off
the accelerator pedal and smoothly press the
brake pedal. Improper use of the brakes can
cause the tires to lose traction, reducing control
and increasing the possibility of an accident.
