LUBRICATION and MAINTENANCE
1) Lubrication:
GREASE PIVOT POINTS
GREASE ALL SIDES
OF LOCKBAR
GREASE LOCK
PLATE (SIDES,
BOTTOM & SLOT)
GREASE SLIDE BEARING
(INSIDE & OUT)
OVERRIDE LINKAGE SLOT
& LOCKBAR ASSIST SPRING
GREASE OVERRIDE
MOVING PARTS
The lock plate mechanism, bell crank and
manual override mechanism should be well
lubricated, in the areas shown, with Super
Lube ® Multi-Purpose synthetic lubricant
grease.
Check for dried, caked or dust/debris
contaminated grease.
Wipe off grease in poor condition and
apply new grease
2) Roller Track
DO NOT lubricate the roller track.
To maintain smooth and quiet operation:
Keep roller track free of any
accumulation of dirt, dust, or other
debris.
If the track does not feel smooth:
Wipe track off with a lint free cloth or scouring pad (Scotch Brite® or equivalent.)
Do not use steel wool, sandpaper, or anything that may leave grit or fibers on the track.
3) Rollers
The roller assemblies are factory lubricated and sealed. They do not require lubrication.
If the track is clean and the rollers still do not roll smoothly, wipe rollers with a clean lint free cloth.
4) Bottom Guide Wear Pads
The door bottom is held in place by two Door Guide plates (each having a nylon wear pad.) Check for
excessive door movement in and out from the wall. 1/16th” movement at the bottom of the door is
acceptable. More than 1/16th” movement requires that the guides be adjusted and/or the wear pads be
replaced. Bottom Door Guide adjustment is detailed in the Mechanical Adjustments section, under
number 4 part b: “To Adjust Door Bottom Lateral Position.”

MECHANICAL ADJUSTMENTS
1) Lock Position Adjustment
The lockbar engages the door at the top and bottom in
both the open and closed positions.
The top locking points are determined by the door hanger
mounted front and rear Lock Brackets.
To Check the rear Lock Bracket position:
oMove the door to the fully closed position
oHold the door tight into the receiver column
oManually raise and lower the lockbar. (move the Lockplate slide by hand as shown.)
When raised and lowered the Lockbar should freely enter and exit the lock bracket notch and not bind or hang
If Lock Bracket interferes with the Lockbar raising or lowering or if the Lock Bracket notch presses on either
side of the Lock Bar then the Lock Bracket should be adjusted.
To Adjust Lock Bracket:
oAllow LOCKBAR to drop into the BOTTOM DOOR GUIDE Notch and into the LOCK BRACKET
oLoosen Lock Bracket Adjustment Nuts
oMove LOCK BRACKET to obtain the vertical engagement with the UPPER LOCKBAR LUG shown
oMove LOCK BRACKET horizontally so Lock Bar freely moves in Lock Bracket notch.
oThe LOCKBAR must move freely up and down in the LOCK BRACKET
Move the door to the full open position and repeat this procedure to position the Front Lock Bracket
Do not adjust the REAR LOCK BRACKET so high that the door can not close when the lockbar is unlocked
manually and then the lock bar release to rest on top of the bottom door guide angle as the door is moved (if
the lock bracket is too high it will run into the upper LOCKBAR LUG preventing the door from closing.)
Note: Because the door Drive Bracket is attached to the Front Lock Bracket, any adjustment of the Front
Lock Bracket must be followed by an adjustment of the door drive bracket.

2) Door Drive Bracket Adjustment
The Door Drive Cylinder rod must not be side loaded.
One test for a side load condition:
oMove the door to the open/locked position.
oManually unlock the door by moving the Lock Plate as shown.
oWith the LOCKBAR lifted, manually move the door towards
the closed position. The door should move easily and may even start to move by itself, this is normal.
oApproaching the fully open position, the effort required to move the door should not increase at all.
oPossible conditions present if door movement becomes restricted approaching the fully open position:
Severely side loaded cylinder rod (Drive Bracket Adjustment required)
Vertically misaligned door - either rubbing the cover or bottom door guide slot (Door Height
Adjustment required, followed by a Drive Bracket Adjustment)
Horizontally misaligned door – Robbing the lock column or cover (Door Lateral Position
Adjustment required, followed by a Drive Bracket Adjustment)
Dirty roller track (Roller Track requires cleaning)
Door Skirt is dragging a high spot in the floor (Door Skirt Adjustment required)
To Adjust the Drive Bracket:
oLoosen the Drive Bracket Adjustment Bolts
oSlightly loosen Cylinder Rod End Nut (allows cylinder rod to slide freely in the drive bracket slot).
oMove the door to the open/locked position.
oTypically the cylinder will push the bracket out to the end of the slot. Move bracket by hand in & out
and back & forth until the bracket / cylinder feels ‘free.’
oSecure the Drive Bracket Adjustment Bolts - ensure the drive bracket does not move while tightening
the bolts.
oTighten the Cylinder Rod Nut with the door in the open position. NOTE: Do not over tighten the
cylinder rod nut and crush the rubber grommet!
oDO NOT bind the cylinder rod
oVerify proper cylinder rod alignment (No Side Loading on Cylinder)

3) Door Height Adjustment
Improper door height may result in the door hanger
rubbing on the cover, or the bottom door guide angle
rubbing on the top or bottom of the bottom Door
Guide Notch.
There are two height adjustment bolts, one for each
side of the door. One complete turn will move the door
up or down 1/16".
Turn the bolt clockwise to raise the door and
counterclockwise to lower the door.
When making height adjustments, first determine how
much change is needed, loosen the axle nut, turn the
adjustment bolt the appropriate amount, then tighten
the axle nut securely and check for proper clearances.
Note: After any adjustment is made to the door height or the door in or out, re-adjustment of the drive cylinder to
the drive cylinder bracket is required. (See Item 2 on preceding page)
