Care and Maintenance
Your new filter requires virtually no maintenance other than periodic cleaning when the lens becomes
dirty or clouded from smoke. A
RC
O
NE ® auto-darkening filters are water-resistant and may be cleaned
by using a soft cloth with soapy water solution, or standard window cleaner. By changing cover plates
frequently you will extend the life of your filter and guarantee the best operation possible. Additional
front and rear cover plates are available from your A
RC
O
NE ® distributor (see Table 1). Do not submerge
filter in water or solution. Storage Temperature 14 - 100°F (-10 - 38°C).
WARNING! Using the wrong cover plates may damage your product, compromise UV/IR
protection, and VOID WARRANTY. Use genuine A
RC
O
NE ® replacement parts to ensure quality
and fit.
iDF81:
The battery located in the external control center will last 3-6
months depending on usage. When the battery voltage is low, a low
battery symbol will flash in the upper left corner of the digital display
(see Fig.5). Replace with battery of same size (typically AA) and volt-
age (1.5 V). The lens will not darken with a weak or dead battery.
Special note for XT540 EVA ® : The extended viewing area is made of highly polished optical material.
It has been hard coated with a scratch resistant finish; however it is not scratch proof. Clean your
XT540 as directed. Please be careful to use a soft clean cloth or eyeglass wipes. Abrasive particles,
such as those in an unclean cloth, could scratch theh polished surface. Install A
RC
O
NE ® cover plates on
both sides of the filter to protect from spatter damage and scratches.
Spatter Protection
SPATTER DAMAGE IS NOT COVERED BY WARRANTY
There are many reasons why spatter can damage the auto-darkening filter. Missing, incorrect,
damaged, or distorted cover plates and excessive spatter build-up in and around the areas where the
cover plates are retained are just a few examples. Any one or combination of these will allow spatter to
enter the filter area and pit the filter glass.
All helmets take a 0.040” thick outside cover plate. A nominal 0.060” outside cover plate will not work.
The Hawk and Eagle Helmets are designed to accept polycarbonate cover plates from the outside of the
helmet without removing other components. This design allows for quick and easy cleaning and cover
plate replacement. The use of an incorrect cover will distort the helmet and result in spatter entering
the filter area.
NOTE: Change your cover plate when it loses its flexibility and/or becomes bowed or distorted. Clean
any build-up from the area where the cover plate is retained.
Flip front designs must use 0.060” thick inner cover plates for protection from particles produced when
chipping or grinding.
A 0.03” thick inside cover plate may be used to protect the inside surface of 5X4 auto-darkening filters.
This size is ideal for digital lenses to allow easy operation of the funtion buttons.
