Assembly
Always be sure the tool is turned “OFF”
before changing accessories, changing col-
lets or servicing your cordless rotary tool.
Collet Nut
To loosen the collet nut, first press shaft lock button and rotate
the shaft by hand until the lock engages the shaft preventing fur-
ther rotation. Your Dremel 7350 is equipped with a shaft lock
mechanism. This mechanism engages the output shaft in 4 sepa-
rate locations on the shaft for easier operation.
Do not engage lock while the Rotary Tool is
running.
With the shaft lock
4
engaged, use the collet wrench
10
to loosen
the collet nut
1
. The collet nut must be loosely threaded on when
inserting an accessory.
Change accessories by inserting the new one into the collet as far
as possible to minimize runout and unbalance. With the shaft lock
4
engaged, tighten the collet nut
1
securely with collet wrench
10
(Fig. 2).
Avoid excessive tightening of the collet nut when there
is no bit inserted.
