COLD WEATHER HEATER PACKAGE

General

The optional cold weather heater package preheats critical
machinery and lubricant sumps during cold weather
shutdown.
When operated in an arctic climate — outside temperature
continuously below 0°F (-18°C) and -30°F (-34°C) — the
crane should be equipped with the heaters identified below
and lubricated with the lubricants listed in Section 5 of this
manual.
CAUTION
Machinery Damage!
Operating in an arctic climate without heaters can damage
machinery during cold weather start-up due to lack of
lubrication.
Heater package described in this section may not provide
adequate protection when operating below -30°F (-34°C).
Contact your Manitowoc dealer for recommendations.
Do not use heater package when operating above 30°F (-
1°C).
Hydraulic Pump Damage!
To prevent damage to pumps, warm hydraulic oil to 60°F
(16°C) minimum before operating crane in an arctic climate.
