Problem Possible Cause Possible Solution
No action required unless other problems
observed.
Inspect/check carriage “full out alignment”
Inspect/check carriage “full out alignment”
Inspect drive chains
Inspect extruded guide rails
Check for identifying marks on all skid pads, etc.
Check supply voltage
Place controller in ‘service’ mode and cycle ramp.
If no obstructions occur, return controller to
‘operating’ mode and clean and lubricate
platform assembly. If obstructions do occur in
‘service’ mode, discontinue use and contact
authorized Braun representative.
Inspect sensor LED during up/down movement. If
LED is intermittent, reposition sensor as
required to ensure sensor remains lit during up/
down movement.
Cut off excess threaded bar ramp supports to
allow proper clearance
Reposition floor level sensor pick-up
Reposition stow level sensor pick-up
Grind leading edges of threaded bar if noise
intolerable
Inspect extruded guide rails
Replace hinge
Inspect/check carriage “full out” alignment
Remove slider. Check for foreign debris, metal
shavings, or spring interference. Clean and
lubricate.
Adjust drive chain tension.
Inspect spring and correct as needed
Inspect, clean and lubricate slider and guide
Inspect and adjust manual release sensor
