INSTALLATION
Table Preparation
Thespreadingtablerequiredmustbesmoothandlevelalong
itsentirelength.Aminimum3feet(1M)clearancearoundthe
entiretableisrequiredforsafeoperation.
To Level Table
Use carpenter's level to check spreading table. Be espe-
cially careful to make sure table joints mate closely. Adjust
table feet as necessary to level table.
Track Installation
The CR500 requiresanencodertracktofeedbackspreading
information to the microprocessor and Guide Wheels to
guide the machine along the table edges. Optional Guide
track is available. Install the track at this time.
Magna Track or Z-Track Installation
Place track sections along table top, end to end, on the
operator's side of the table as they will be mounted. Mount

Encoder Track Installation
Proper installation of the encoder rail is very important for
accuratemachineperformance.Theencodertrackmustbe

each 8' section of track, as shown. Mount encoder track to
table legs. When ALL sections of track are mounted, the

length. If belt must be spliced, make sure that ribs of belt
remain at consistent spacing, otherwise encoder will not
functionproperly.
Place Machine On Table
The CR500 weighsapprox.1,400lbs.(636Kg.)uncratedfor
a 72" machine. Wooden braces are strapped across the
underside of its cross channels. Forklift arms should be
raised to these braces when machine is lifted.
CAUTION
When placing forkliftarmsundercrosschannels,use
care not to damage the drive shafts.
When the CR 500 is shipped the Safety Limit Switch
Assembly, Encoder Assembly and the Guide Wheels are
removedandmustbeinstalleduponinstallation.
Place the CR 500 on the table between the end markers
(marksdesignatingleft and right endof spread). Machines
equippedwithgroovedwheelsmustbeplacedonthelipofthe
