Stopping the Gate
Most models (except StrongArm 15 and 40) employ a time delay
Soft Stop system. Additionally, brake valves are used to control the
stopping of heavy or fast moving gates. These valves are exclusive
to HySecurity operators. They are independently adjustable to
allow the gate to stop predictably and without banging.
Starting the Gate
To accommodate for loads moving beyond one foot per second,
it is necessary to Soft Start the load gently and stop it smoothly.
HySecurity accomplishes Soft Start with another exclusive feature
we call an Accumulator With Out Gas (AWOG), which diverts
some of the start-up hydraulic ow, accommodates for the load,
and starts the gate smoothly, similar to letting your foot slowly off
a car clutch without any lurching.
The downward facing AWOG (shown right) improves the life and
performance of a gate system and never needs adjustment.

NOTICE: Before checking the internal mechanisms of the operator, turn off all power switches.
The mechanical maintenance for the StrongArm is not in depth or difcult, but should be performed on a
routine basis.
Schedule regular maintenance:
Check for signs of rust. The operator chassis is zinc plated which is corrosion-resistant, but some
environments may increase the rate of corrosion. If any areas of rust are found, reduce the spread of
corrosion by treating the areas with a rust inhibitor.
Grease the hydraulic cylinder every 50,000 cycles. Use NLGI #2 Grade Moly EP (Extreme Pressure)
lithium base grease only and apply it with a standard grease gun. Grease other main shaft bearings
every 100,000 cycles.
Check the motor. DC motors contain carbon brushes which wear over time and must be replaced.
Failure to replace the brushes will result in damage to the DC motor. Brushes should be inspected
every year in high usage applications or every 100,000 cycles and replaced as needed.
Replace worn-out batteries. Refer to Clock Battery Replacement on page 116.
