cut with a hacksaw or disc grinder is too large for
this trimmer so that the trimmer does not rotate
and it is not possible to remove flange.
CUTTER LIFE AND REPLACEMENT
1. Cutter life
As is shown in Fig. 15, repeated cutting can cause
breaking and warping of the cutter edge. Using the
cutter in this condition can produce flange on the
cutting location of the studs so that the threads are
distorted. This will prevent clean cuts and make it
impossible to insert the nut.
Breaking
As is shown in Fig. 16, the edge is found on four
locations on the cutter. Use the method described
below to change the attachment direction of the
cutter to allow a total of four usages.
If the nut does not fit on the screw due to breaking
and warping of the edge, change the cutter
attachment direction to use the edge without
breaking and warping or replace with a new cutter.

2. Changing the cutter attachment direction or replacing
the cutter
(1) Before removing:
1 Pull the switch lightly to slowly operate bracket (A)
and set the cutter in an open condition.
2 Set the forward/reverse switching button to the
position.
3 Remove the rechargeable battery from the main
unit.
(2) Removal
Use the accessory hexagonal bar wrench to remove
the hex. socket hd. bolt. It is now possible to remove
the cutter and spacer.

2 There is directionality for cutter attachment in order
to change the position of the edge. Check that the
cutter has been attached so that the marking on
the cutter surface can be seen on bracket (A)
(movable side) when seen from the main unit viewed
from the front or that the notch on the cutter
surface on bracket (B) (fixed side) can be seen
(Figs. 5 and 19).
DO
3 If there is breakage or warping on the cutter edge
or if there are bulges on the cutter attachment
surface, use a hammer to the areas flat.
4 Use brush to remove the filings attached to the
cutter attachment groove on the bracket.
CAUTION
As shown in Fig. 20, if the cutters are combined
in such a way that both printed sides or both notch
sides are facing out, the pitch of the threads on
the studs and the threads on the cutter will not be
in agreement. This can cause damage to the cutter
edge or cause wear to premature damage to the
main unit.
