Model SWD Maintenance
Battery Maintenance
The gel-cell batteries in this operator require no routine
maintenance. For assured continued performance, they
should be replaced every year. If power is to be removed
for one week or more, disconnect the negative wire from
the batteries as this will prevent deep discharging. Fully
charge before use after storage or upon initial installation.

DC Motor Brush Replacement
Brushes should be inspected every 100,000 cycles or
yearly, whichever comes first. The motor has two brushes,
one on each side.
Original brushes are approximately 3/4" long and should
be replaced when they are 1/2" long, or sooner. If brushes
are allowed to wear beyond this point, permanent damage
to the motor may result.
To inspect the brushes: (1) remove the retaining cap with
straight-blade screwdriver; (2) carefully pull assembly
straight out; (3) measure the remaining brush material.
To reinstall: (4) place the brush in holder, aligning the
brush's rounded indentation correctly with motor shaft;
(5) gently push in the spring and align metal contact with
oval slot in the brush holder, then push it in with retaining
cap. Hold the cap in place and thread the cap into brush
holder. Do not overtighten or cap will crack!
Repeat for the other brush.
