SAFETY ELEMENT SERVICE
The safety element is not intended to be cleaned. For maximum engine protection and
air cleaner service life, replace the safety element with a new safety element every third
primary element change or cleaning or as indicated by the Donaldson Safety Signal
ELEMENT CLEANING METHODS
Clean Duralife element by one of the following methods:
Compressed air or washing.
Compressed air is recommended when element will be re-used immediately because
a washed element must be dried before re-use. However, washing does a better job
and-must be used when exhaust soot has lodged in fine pores of the filter media.
Use Donaldson D-1400 detergent which contains a special additive for removing soot
Replace element after six (6) cleanings or annually, whichever occurs first.
Do not remove plastic fin assembly back-flowing with compressed air or washing will
remove dust from beneath the fin assembly.
