Model SLD 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 1/4” 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..
