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.

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.

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.
