Verify that the desiccant cartridge in the air dryer is in good condition, and
that the air dryer discharge valve heater is operating correctly.
Verify that the engine cold start ether injection system is operating correctly.
To check the ether injection system at engine temperatures above 30 F (-
1 C), it will be necessary to by-pass the engine temperature sensor using a
Without heating the engine excessively (see Section 6), verify that the
carrier cab heater and defroster controls are operating correctly, and that
the engine cooling thermostat is operating correctly (i.e. is not stuck open or
Verify that the engine belts and hoses are all in good condition.
Verify that all cab door and window seals are in good condition, and that the

Conduct a thorough examination of all structural components of the crane
(boom sections, turntable, carrier frame, outriggers, all load-holding
cylinders, etc.) and verify that no cracks or other evidence of failures exist.
Check-Out at Prevailing Ambient Temperatures.
Excessive heating of the low temperature fluids and
lubricants can cause degradation of those fluids, and
resulting in potential equipment damage.
At prevailing ambient temperature, conduct a full functional check-out of the ATEC
and its pertinent sub-systems, including all warning and status indicator lights, and the Load
Moment Indicator system, to verify that all systems are performing correctly following the
preparations. Note that care must be taken if the prevailing ambient temperature is above 70 F
(21 C), to avoid unnecessary and excessive heating of the engine, transmission and the hydraulic
Operation in Extreme Heat.
When operating in extreme heat, keep all engine air passages and hood
openings clean and free of obstructions.
Do not completely fill the fuel tank. Leave room for expansion.
Ensure diesel engine is serviced with proper lube oil for high temperatures.
