ZOOM GEAR ASSEMBLY INSTRUCTIONS

FDM parts - a brief description
Xit 404 manufactures a number of its parts using a process called Fused Deposition
Modeling (FDM) This process involves extruding a thread of plastic and laying it down
in thin layers to build a part. This enables us to supply you products that enhance your
underwater photography and videography.
Care and Maintenance
The FDM part is impact resistant and will withstand most drops from table height.
However, as with all plastic parts, they cannot withstand excessive pressure and force
without breaking. Being careful means handling the product during assembly with a light
touch, do not force.
If your part gets wet let it drip-dry for about an hour. If you have to pack it before it is dry
then wrap it in something absorbent such as a paper towel, tee shirt or sock and put it into
a plastic bag. This will keep your other parts from getting dripped on.
FDM Plastic Part Warranty
FDM parts are guaranteed to be free of manufacturing defects for a period of one year
from date of purchase. Unnecessary force can cause excessive wear and possibly break
the parts voiding warranty. Damaged or broken parts will be inspected. If Xit 404 determines
that the parts were misused or abused, warranty will be void. Valid purchase receipt is
required for all warranty claims.
