to fasten ends of lip seals

If necessary pull the lip seal along at different points

along the inserted length. Insert the 4 straight pins from

the hardware kit into the ends of the lip seal grooves to

keep the lip seals from pulling away from the ends of the

scale case. Trim the lip seals ends with a pair of scissors

so that there is an overhang of approximately [1/8"] 3mm

at each end.

• Attach the right end cap with M3 x 12 CHM screws

provided in the hardware kit. Tighten these screws

securely to compress the end cap gasket.
