General Information

Driving Tips

For a smooth start, always select an initial starting gear that will pro-
vide sufficient reduction for the load and terrain.

Always use normal double-clutching procedures when making lever 
shifts.  (See “Double-Clutching Procedure” Section).

Never slam or jerk the shift lever to complete gear engagement.

Never coast with the gear shift in the neutral position.

Never downshift at too high of a road speed.

In most cases, depending on the engine and the axle ratios, you can 
save valuable fuel by operating the engine at less than governed 
RPM while cruising in 7th.

Double-Clutching Procedure

When ready to make a shift:

1.

Depress pedal to disengage clutch.

2.

Move gear shift lever to neutral.

3.

Release pedal to engage clutch.*

a.

Upshifts - decelerate engine until engine RPM and road speed 
match.

b.

Downshifts - accelerate engine until engine RPM and road speed 
match.

4.

Quickly depress pedal to disengage clutch and move gear shift lever 
to next gear speed position.
