How to check the DS 402 foreline pump to determine if the pump needs maintenance.
The oil cleanliness and oil level in the DS 402 foreline pump should be checked monthly. Perform maintenance as needed, based off the monthly check. The DS 402 oil should be replaced at least once every three months, but the type of samples and number of samples analyzed may shorten the life of the oil.
Caution: Only use Agilent Recommended pump oil appropriate for the DS 402 foreline pump. Using a different oil can substantially reduce pump life and invalidates the pump warranty.
