Without a properly installed safety
reversal system, persons (particularly
small children) could be SERIOUSLY
INJURED or KILLED by a closing door.
• Incorrect adjustment of door travel
limits will interfere with proper
operation of safety reversal system.
• After ANY adjustments are made,
the safety reversal system MUST
be tested. Door MUST reverse on
contact with 1-1/2" high (3.8 cm)
object (or 2x4 laid fl at) on fl oor.
To prevent damage to vehicles, be
sure fully open door provides adequate
clearance.
