EXTREME COLD WEATHER OPERATION PROCEDURES
1) Consult the power unit engine operator’s manual for all cold weather operating procedures and precautions.
2) Select gear and bearing lubricants that are compatible with expected climatic conditions.
3) Select hydraulic fluid that is compatible with expected climatic conditions.
4) Allow hydraulic fluid to circulate for approximately 20 minutes after starting the power unit, prior to activating the bypass valve
to allow fluid to circulate to tong. If the power unit is equipped with an oil temperature gauge, ensure that the fluid has reached
operating temperature as specified by hydraulic fluid data sheet.
5) Allow for adequate drying of moisture (prior to lubricating) when cleaning tong parts in cold weather.
