OPERATE TRANSMISSION - CONTINUED
Operate Transmission.
2.
a.
Depress service brake pedal and hold.
b.
Unlock shift lever lock.
c.
Release parking brake.
d.
Move transmission shift lever to position 1.
e.
Release service brakes and begin to move out.
f.
Upshift one position at a time as engine and ground speeds increase.
g.
Downshift one position at a time while at the same time reducing machine speed with service brake applications.
OPERATE PARKING AND EMERGENCY BRAKES
1.
Use parking brake to secure vehicle against movement when parked. NEVER leave operator's cab without applying
parking brake.
2.
Do NOT use parking brake to stop a moving machine. Use service brakes instead.
3.
If service brakes fail, apply brakes in an emergency using emergency brake control knob.
OPERATE DIFFERENTIAL LOCK
CAUTION
Excessive wheel spin and uncontrolled wheel spin can cause accelerated wear to power train compo-
nents and tires.
Improper use of differential lock control may damage components of differential lock.
1.
Engage differential lock control to prevent wheel slippage when traction is poor. Power will be equally distributed to
each wheel and both wheels will turn at the same speed.
2.
Anticipate using differential lock before wheel slippage occurs. Do NOT engage differential lock while one wheel is
slipping. Decrease engine RPM until wheel stops spinning, then engage differential lock.
3.
Do NOT engage differential lock at high speeds.
4.
Do NOT turn (steer) machine while differential lock is engaged.
5.
Differential normally unlocks when pedal at floor is released. In areas of high resistance, it may be necessary to turn
machine slightly and decrease engine RPM, to assist in unlocking differential lock control.
OPERATE STEERING (TRACTOR AND WATER DISTRIBUTOR COMBINATION)
1.
Operator controls machine steering using steering wheel to operate steering system.
2.
Avoid over steering. Become familiar with steering characteristics of machine before attempting maneuvers in limited
space.
NOTE
Machine has no secondary steering system.
3.
In the event of steering system failure, perform the following:
a.
Attempt to steer machine to a safe location and stop. Apply parking brake.
b.
Shut down engine and troubleshoot malfunction.
c.
Do NOT operate machine until problem has been corrected.
