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.

BRUSH REPLACEMENT

Brushes should be inspected every 100,000 cycles, (200,000 for BGU-D) 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, remove retaining cap (A), with straight-blade screw- driver, and carefully pull assembly straight out. Measure remaining brush ma- terial (B).

To reinstall, place brush in hold, aligning rounded indentation (C), correctly with motor shaft. Gently push in spring and align contact with oval carrier, push in with retaining cap (D). Hold in place and thread cap into brush carrier. Do not overtighten or cap will crack! Repeat for other brush.

If brushes require replacement, order kit #2510-243.
