Check: With the machine front cover removed. Check the belt
tension for tautness by pressing it with the index 昀椀nger (Figures
7.1–7.2). Press the ver琀椀cal center of the belt with approximately
2 lbs of pressure. The belt should de昀氀ect about ½". Proper
belt tension provides for some belt 昀氀exibility under light 昀椀nger
pressure, but should not be so 琀椀ght as to bind the machine.
Double-check the tension by rota琀椀ng and rocking the hand wheel.

and any of the driven components. Con昀椀rm also that there is an
immediate transfer of mo琀椀on to all components driven by the
belt, from the handwheel to the hook.
Important: Do not over-琀椀ghten the belt as this will make the
machine too 琀椀ght, the handwheel more di昀케cult to turn, create
more belt noise, and also cause other undesirable issues.

• Insert a 4 mm handle hex tool through the hole in the main
frame cas琀椀ng (Figure 7.2). Loosen the socket-head belt tensioner
screw. Adjust the belt tensioner by pressing down on the
tensioner and while holding down on the tensioner re-琀椀ghtening
the belt tensioner screw
(Figure 7.2).
• Note: This adjustment can only be made with the front cover o昀昀
