How do you add hydraulic fluid to electric gate arm?

To add hydraulic fluid to an electric gate arm, first ensure the gate is powered off and safely secured. Locate the hydraulic fluid reservoir, typically near the hydraulic cylinder or motor. Remove the reservoir cap, and using a funnel, pour the recommended type of hydraulic fluid until it reaches the appropriate level indicated on the reservoir. Replace the cap securely, and check for any leaks before restoring power to the gate.
