The power head drive unit limit lever protrudes up
through the rail/chain assembly sensing plate. Take care
not to bend the lever when assembling. Slide the power
head drive unit forward until the gear meshes with the
rail/chain assembly drive gear. Check to make sure the
front guide tabs on the power head unit are securely
locked on the rail/chain assembly.
STEP 5:
The power head drive unit should be move
forward until all play between the gears has been
eliminated, but no additional force should be used
that could cause pressure on the motor (power head
unit) drive gear. Tighten the two 5/16" lock washer
nuts on top of the power head drive unit that were
loosened in Step 2 above.
When the opener is first activated the paper shim will
be ejected. The paper shim should have the profile of
the gears to indicate the proper mesh between them.
STEP 6:
Recheck
the nuts used to secure the Rail/
Chain assembly to the Power Head Unit, making sure
they are tight.
Assembly is now complete and you are ready to
begin installation of the opener.
