f. Restart engine and check to insure all
controls are properly positioned for starting.
Run engine for 3 to 5 minutes to charge
battery.
g. Turn ignition switch OFF and service
vehicle.
Emergency Window Removal
If it is necessary to rescue an operator that is
trapped in the cab, remove the front glass. Using
any available pointed object such as a knife,
screwdriver or stick, pry out the seal lip of the
weatherstripping. Pry in under the glass to raise
it so that it can be removed. This same method
can be used on any of the side or rear windows
for emergency purposes.
An able and conscious operator can also exit the
cab by placing his feet against the glass and with
moderate force, push the glass out of front or rear
windows.
Extreme Heat
Like extreme cold, extreme heat requires that
precautions be taken with respect to the cooling
system, battery and lubrication. Protect the
vehicle by performing the following recom-
mended procedures:
1. Lubricate with correct lubricants. High tem-
peratures necessitate the use of lubricants
which are both higher in viscosity and resist
deterioration at higher operating tempera-
tures. Refer to the Lubrication section,
Appendix B and use the lubricants recom-
mended for the expected temperatures.
2.
Crankcase oil is particularly important be-
cause it helps dissipate heat. Check the oil
level frequently and add oil as required to
maintain the correct level. Low oil will
hinder heat dissipation.
The cooling system is pressur-
ized. Use extreme caution and
proper protection when removing
radiator cap after operating tem-
perature is reached. When
removing cap, loosen it slowly to
the left, then pause a moment.
Steam and hot gases will be
escaping through the radiator
cap; avoid being burned by these
gases. Continue to turn cap until
it can be removed. Failure to
follow this procedure could cause
SERIOUS INJURY.
Prevent overheating. To insure proper cool-
ant circulation, drain and flush the cooling
system. Clean any foreign matter from the
radiator cooling fins and core air passages.
Replace defective hoses and tighten hose
clamps. Eliminate any leaks detected and fill
the system with a 5070 solution of ethylene
glycol and water. A corrosion inhibitor is
also recommended.
Engine overheating due to loss of coolant will
most often be corrected by SLOWLY replac-
ing the lost coolant with engine idling.
Water containing larger than normal concen-
trations of salt or minerals should not be used
in the cooling system. Salt will cause corro-
sion and mineral deposits will collect on the
coolant passage walls. Both processes inhibit
proper cooling.
