140 OPERATION
Double-Clutching
Double-clutching is a way to bring the speed of the transmission gears into synchronization
so that the shift can be made without a clash. The engine is used to speed up the countershaft
for a downshift and to slow it down for an upshift.
Note:
For all nonsynchronized transmissions, double-clutching is necessary on downshifts
and upshifts. It is advisable to use the torque-limiting clutch brake to engage first and
REVERSE gears and to double-clutch for gear ratio changes.
1 Depress the clutch pedal and shift to NEUTRAL.
2 Release the clutch pedal and increase (downshift) or decrease (upshift) engine speed until
it roughly corresponds to the road speed of the desired gear.
3 Depress the clutch pedal and complete the shift. Then release the clutch pedal.
POWER TAKE-OFF (PTO) OPERATION
If the vehicle is equipped with a Power Take-Off (PTO) unit, be sure to read the following
section.
PTO Precautions
DANGER
Power Take-Off (PTO) units and related
equipment can be very dangerous. Any
PTO installation, repair or replacement
should include a warning indicator light
which indicates PTO engagement. The
light must be located close to the PTO
control and clearly visible to the operator.
DANGER
PTO units are driven by engine or
drivetrain components (flywheel,
crankshaft, transmission). Do not attempt
to service the PTO and related units unless
the engine is shut down.
DANGER
Always keep body parts and loose-fitting
clothing out of the range of drivetrain
components, or personal injury may result.
DANGER
Always be aware of the current PTO status
(engaged or disengaged) and the position
of the vehicle body (dump body controlled
by PTO, etc.). Be sure to disengage the
PTO when not in use.
