coolant temp
160 to 210 F
*60 to the 210 F
transmission temp
140 to 220F
engine oil pressure
12 psi @ idle
50 psi @ rated rpm
cab instrumentation indicator lights
12 LED
fuel tank capacity
47 gallon
windshield wiper switch
two positions for two speeds
Drive
100% pedal travel at 2100 rpm
lower gears 2, 3, 4
lower ranges provided greater engine braking for going down grades ( the lower the range, the greater the braking effect) and maximum torque and traction for steep grades and/or adverse road conditions
first gear
when pulling through mud or whenever max traction is desired, when maneuvering in tight spaces, or while driving up or down steep grades. First rate provides the vehicle with its maximum driving power and maximum engine braking power. Push the down arrow on the selector until first range appears in the display window
reverse
always select N(neutral) when transitioning
idle longer than five minutes
high idle switch
air brake audible alarm and warning
60 psi
use extreme caution when operating the vehicle with either air brake section charges less than
60 psi
spring brake automatically apply
40 psi in both systems
- If air pressure is lost in the rear (primary) service brake section, the brakes will be modulated by pressure from the secondary reservoir allowing a few brake applications before the spring brakes are automatically applied. If air pressure is reduced to approximately 40 psi in both systems, the spring brake valve will automatically apply.
what must be applied prior to using front wheel lock
spring brakes (maxis)
how many levels does telma have
off, 1, 2, 3, 4
load manager checks voltage every
30 seconds
first accessory deactivated will be turned off for at least how many minutes
5 minutes
*turned off for at least 5 minutes and must register 1 min
of acceptable voltage to turn back on within that 5 minute duration. Load manager will start to turn on accessories at the rate of one accessory every TWO minutes

if no oil pressure within how many seconds, stop the engine and check lubricating system
10-15 seconds
oil pressure should not fall below __ psi at 1800 rpm and normal operating pressure should be higher
28 psi
try not to shut down engine unless coolant temp is __ F or less
195
*stopping a turbocharged engine immediately after high speed operation may cause damage to turbo as will continue to turn w/o an oil supply to the bearings. Failure of turbo oil seals and or bearings are the likely results of this practice
