Milwaukee · M18 FUEL Vacuum Pump
When the pump is used in environments below 20 degrees Celsius, it will automatically reduce its initial operating speed. This 'cold mode' warms up the oil and motor to ensure optimal performance. The pump will return to normal speed on its own.
Click steps to track your progress.
Recognize that this is a normal warm-up procedure in cold conditions.
Allow the pump to operate at the reduced speed; it will automatically return to normal speed.
Ensure the pump is primed with oil before operation, especially in cold conditions.
Do not try to force the pump to full speed immediately.
