Section 7: Adjusting the Motor Drive/Timing Belt
Tension
The Regalia machine utilizes a single motor drive/timing belt system. The belt is a double-sided round-tooth belt.
Tools required: 5 mm handle hex tool and 13 mm open end wrench .
Check: With the machine front cover removed. Check
the belt tension for tautness by pressing it with your
index finger. Press the vertical center of the belt with
light pressure. The belt should deflect about ½”. Proper
belt tension provides for some belt flexibility under light
finger pressure, but should not be so tight as to bind
the machine .
Double-check the tension by rotating and rocking
the hand wheel. Confirm that there is no backlash
or play between the belt teeth and any of the driven
components. Confirm, also, that there is an Immediate
Transfer of Motion between the handwheel and
the hook.
Â
IMPORTANT: Do not over-tighten the belt as this
will make the machine difficult to turn and may
cause other undesirable issues, including more
belt noise .
If a correction is necessary:
• Insert a 5 mm handle Allen tool into the fixing screw
in the center of the tensioner, and loosen it until you
can turn the outside of the tensioner with the 13 mm
open end wrench.
• Turn the tensioner with the 13 mm wrench clockwise
to tighten or slightly counter clockwise to loosen the
belt tension .
3. Tighten the center fixing screw with the 5 mm handle
hex tool firmly.
Â
IMPORTANT: Do not tighten the belt by turning
the 13mm wrench counter clockwise as this
will pinch the belt in the small area between
the tensioner pulley and the motor pulley. Only
tighten the belt by turning the 13mm wrench
clockwise.
