MAINTENANCE SCHEDULE
Regular maintenance and inspection of the Ricon FoldOver ramp provides optimum performance and reduces the need
for repairs. Maintain the ramp as directed in
Table 3-2
. Perform ramp maintenance more frequently during heavy use
(more than 20 cycles per day).
CAUTION!
~ This Ricon Product Is Complex ~
Required warranty period maintenance and repairs must be done at a Ricon dealer or
trained and qualified service technician. Improper maintenance, use of non-Ricon
