Changing Collet Inserts:

The Marvel 42 is supplied with both 1/8” and 1/4” collet inserts. To change the collet insert,

loosen and remove the collet nut and insert the desired collet for the bit you intend to install in

the router. Replace the collet nut but do not tighten it fully unless there is a router bit inserted

into the collet as it is possible to permanently distort the collet insert doing this. This could make

inserting bits into the collet difficult or cause you to need to replace the collet insert.

Inserting A Router Bit into the Collet:

With the collet nut loose, slide the router bit into the collet insert. Make sure that you have at

least 3/4” of the router bit shank inserted into the collet. Do not bottom out the bit in the collet. If

you insert the shank to the bottom of the collet bore, make sure to pull it out at least 1/16” to 1/8”

to allow the collet insert to properly secure the router bit in the collet. There is a button on the

motor housing that will lock the spindle to allow you to tighten and loosen the collet nut using

the supplied wrench. It will be necessary for the spindle to rotate until the spindle lock pin

engages the locking hole on the spindle. Before tightening the bit, make sure the flutes of the bit

are completely visible outside the collet. Otherwise, it can result in broken bits and possible

injury. The power cord should be unplugged from the power source when making bit changes to

prevent the router from being turned on by accident.
