2.
Driving.
a.
Drive at slower speeds.
b.
Give signals sooner.
c.
Apply brakes sooner to give early warning of intention to stop. This will also help to avoid skidding.
d.
Maintain double the normal distance from machine ahead.
e.
Keep windshields, mirrors, and lights clean and free of snow and ice.
f.
If approaching a difficult stretch of road, stop and inspect road carefully before driving on it.
g.
Select transmission gear range that best suits driving condition.
3.
Stopping.
a.
Ease up on accelerator, leaving machine in gear.
b.
Apply service brakes lightly and evenly. DO NOT pump service brake pedal.
c.
Always avoid sudden braking.
4.
Parking. If parking on icy, slushy, wet, or muddy surfaces, place boards, brush, or other materials that will provide trac-
tion underneath tires. This will guard against tires freezing to the ground or becoming pocketed in ice, and will provide
some traction when machine is started and moving again.
FORDING
0006 00
The RTCH can be forded in water depths up to 60 in. (1.50 m). Observe the following precautions when fording any
body of water:
1.
Before Fording.
a.
Check depth of water at its deepest point. Do not ford even the narrowest stream more than 60 in. (1.50 m) deep.
b.
Ensure bottom is level enough for fording.
c.
Ensure engine is operating at full efficiency.
d.
Set transmission speed in low ranges.
e.
Check tire pressure before entering water and adjust as needed:
(1)
Front tire inflation should be 70 psi (480 kPa).
(2)
Rear tire inflation should be 40 psi (275 kPa).
2.
During Fording.
a.
Enter water slowly to minimize waves and backwash.
b.
Do not exceed speed of 3-4 mph (5-6 kph).
c.
If stalling occurs, notify Organizational Maintenance.
3.
After Fording.
a.
Within 10 minutes of fording, check the following fluid levels:
(1)
Engine oil
(2)
Transmission oil
(3)
Fuel
(4)
Hydraulic oil
b.
Have Organizational Maintenance check:
(1)
Each differential
(2)
Each wheel
c.
Thoroughly wash machine after saltwater fording.
