Warm-up Procedure
A warm-up procedure is recommended at each start-up and
is essential if ambient temperature is below 4°C (+40°F).
Run the crane at idle with the hoist control lever in neutral
and allow sufficient time for the hydraulic system to warm up.
Operate the hoist at low speeds, forward and reverse,
several times to prime all lines with warm hydraulic oil and
circulate lubricant through the planetary gear sets.
