Fixation And Setting Of Push Rod For Articulated Barrier - Chamberlain LiftMaster Professional BARS1-LE Manual De Instrucciones

The articulated pole can only be shortened at the end behind the articulated mechanism.
All other parts are already adjusted to correct measurements ex works.
7.9 Fixation and setting of push rod for articulated barriers
Familiarize yourself with all parts of the push rod. See illustration.
Attention: 2 people necessary!
Adhere to the following course of action:
• Attach the two screws on the left and right hand side of the articulated pole-fittings and tighten
them (if necessary use oil spray). These screws serve for the adjustment of the fitting.
• Insert axle around which the push rod will rotate. Pay attention to correct alignment. One side has
a slanted edge and faces towards the push rod. Tighten by means of acorn nut, washer and
circlip (as shown) in the long slot (in the centre)
• The barrier spring must not or hardly be tensioned
• Now install the barrier pole as afore described
• Release barrier and position horizontally
• Insert push rod. The push rod is pre-assembled but not set precisely. Turn rod as long as it takes
to reach correct measurement. The threads are left/right threads. Pay attention when sliding
bearing onto axle! Mind the correct side! In the eye of the push rod's bearing there is a circlip. It
must point towards the barrier otherwise the clip will be jammed by the nut. This is why the axle
has a slanted edge on one side.
• Use long acorn nut with washer and circlip
• Setting: by rotating in the centre of the push rod the position of the barrier pole can be adjusted
• The slotted hole serves the alignment in the horizontal position
• The push rod serves the alignment in the open position
• Final setting is not advisable until barrier is operated electrically and limits are correctly set
7.10 Model barrier left / right and conversion
The barriers are pre-assembled in the following versions: "Left" or "Right".
Principally all parts of the barrier can be used both ways. Retrofitting must be authorized in writing
by the manufacturer.
