To prevent possible SERIOUS INJURY or DEATH:
• DO NOT connect electric power until instructed to do so.
• If the door lock needs to remain functional, install an
interlock switch.
• ALWAYS call a trained professional door serviceman if door
binds, sticks or is out of balance. An unbalanced door may
not reverse when required.
• NEVER try to loosen, move or adjust doors, door springs,
cables, pulleys, brackets or their hardware, ALL of which are
under EXTREME tension and can cause SERIOUS personal
INJURY.
• Disable ALL locks and remove ALL ropes connected to door
BEFORE installing and operating door operator to avoid
entanglement.

HANDING IDENTIFICATION
For MH and HMS models with manual hoist hand
chain systems, the handing of the operator must be
determined at the time of order. The handing is
indicated by last letter of the model name (R or L).
(Illustration shows right handed operator. Left handed
operator will have hoist chain on the left side.)
The hand chain wheel can not be switched on site. If
your installation causes the hand chain to hang in the
door opening, hook the chain off to the side near the
top of the door jamb.
