Leveling And Balancing Arm - HySecurity StrongArm 14F Programming And Operations Manual

eVelinG and
The StrongArm gate operator is pre-adjusted at the factory to perform correctly with the barrier arm shipped.
If the arm length, or weight is changed, it may be necessary to re-adjust the gate operator to perform correctly.
To properly adjust the StrongArm gate operator, perform all adjustments in the sequence listed. Be certain to
disconnect the power before performing any adjustments!
Arm Leveling: To adjust the gate arm with the threaded eyebolt at the base of the hydraulic cylinder take the
following steps:
CAUTION
DO NOT remove the pin from the eyebolt. Neither the hydraulic cylinder nor the eye bolt needs to be removed
to adjust the gate arm height.
1. With the gate in the closed position, use a needle-nose pliers to remove the top and bottom safety
C-clips from the eye bolt.
2. Use a 1½-inch wrench to loosen the top nut to release tension on the eye bolt.
3. Move the gate arm and stabilize it at a level position.
4. To maintain the level position, hand-adjust the bottom nut up or down.
NOTICE: You may initially need to unscrew the bottom nut to allow the gate arm to reach a level position.
5. To lock the gate arm's level position, tighten the top nut. Nut torque should be at least 100 ft-lbs to
prevent loosening during extended operation.
6. Re-insert the top and bottom safety C-clips so a gap (less than 1/8 inch) is between the nut and C-clips.
7. Run a gate test by cycling the gate arm open and closed.
8. If the arm height needs further adjustment, repeat steps 1 through 7.
Balance: Before adjustments can be performed correctly, the operating weight of the arm must be verified to
be within the proper range for this machine.
NOTE: A 9/16-inch lock nut secures each adjustment valve; pressure relief, brake, and manual bypass. The lock nut must be loosened
before you can adjust the valve. Leave the lock nuts loose until you complete all the adjustment steps.
1. Pull and twist release the manual bypass valve, then manually lift the arm from a position ten feet
distant from the operator.
2. The arm should appear to weigh forty pounds, or less, regardless of the length or actual weight of the
arm.
3. If the operating weight of the arm is heavier than our maximum specification, the operator is
overloaded which adversely affects both automatic and manual operation.
4. The only remedy for an arm that is too heavy is to reduce the length of the arm, or add additional
counterweight which is described in the next section.
