CAUTION
Before checking the internal mechanisms of the operator, turn off all power switches.
The StrongArmPark DC mechanical maintenance is not in depth or difcult, but should be performed on a
routine basis. The operator chassis is zinc plated, but some environments may speed corrosion of this plating.
Schedule regular maintenance and look for the following:
• Assess that the drive belt has the proper tension. Check for drive belt wear. Fraying edges or missing teeth indicate
that the drive belt needs to be replaced.
• Check for signs of rust. If any areas of rust are found, reduce the spread of corrosion by treating the areas with a rust
inhibitor.
• Replace worn-out batteries.
• On the StrongArmPark DC 14 spring assembly, apply grease to zerk tting and upper rod end.
