Cybex Arc Trainer 620A/629A Owner’s Manual

There are two drive belts that may become loose, worn or

cracked. See Figure 1.

Primary Belt - This is the wider of the two belts.

It has grooves that keep it aligned on the large

upper pulley. Unless the unit has been serviced

and not put back together properly, it is unlikely

that the primary belt will become loose because it

is a stretch-fit belt.

Secondary Belt - This is the narrower of the two

belts. It has grooves that keep it aligned on the

flywheel’s drive pulley. It is unlikely that the

secondary belt will become loose because it is a

stretch-fit belt. Unless the unit has been worked

on and not put back together properly, it is

unlikely the tension will change.

Follow this Drive Belt Maintenance procedure to

ensure that the belts are tensioned properly and

in good condition. See the Service Schedule in

this chapter for a minimum schedule for checking

the belt tension and condition. NOTE: If a belt has

cracks or appears worn, it must be replaced

immediately by a qualified service technician.
