Manual Release System: If the release cable is difficult to pull to unlock the system, inspect the guide and slider shown in Photo T.

Confirm no dirt, metal shavings, or other foreign debris are pres- ent and restricting the slider. Also, check compression spring to verify the open end of the spring is not binding the movement of the slider.

Manual Release Sensor Adjust- ment: Inspect manual release sensor to confirm LED is lit when slider is precisely released from axle. The distance from the sen- sor head to the pick-up must be approximately 4mm or less at this precise point to ensure Manual Release Locked/Unlocked signal is accurate. Adjust distance by mov- ing sensor in/out via the sensor’s two locknuts. Operate several times after adjustment to confirm new setting is correct.

Right Drive Chain

Light Oil can be applied to chains (small amount)

Chain System: The ramp utilizes a 3 chain system. Two drive chains, left and right, provide the means for the carriage to travel along. The third chain, in the rear of the cassette, interlocks the left and right drive chain to rotate in sequence (or equal time).

During normal operation, none of the 3 chains move. However, during manual operation of the ramp, all 3 chains travel equal distances. To lubricate, a light oil may be used on the chains, but should be limited to reduce the possible buildup of debris.
