Adjusting the Toolhead Trolley
Over time, the Toolhead trolley may come out of adjustment, resulting in imprecise cuts,
engraving and marking operations.
Remove the Toolhead
1. Remove the tensioning springs on each side
of the Toolhead. The tensioning springs are
located on the backside of the Toolhead. Using
a pliers, grab the bottom loop on each spring.
Pull down on the spring to release the loop
from the tensioning spring mount.
2. Using the same method, remove the Engraver
retraction spring at the front of the Toolhead.
3. With the tensioning springs removed, the Toolhead will be
resting on the Engraver tensioning spring mount at the top
of the Toolhead. Place a ⅜ in. wrench on the nut on the
backside of the Engraver tensioning spring. Holding the
nut secure with the ⅜ in. wrench, use a ⅛ in. Allen wrench
to remove the Engraver tensioning spring mounting screw
and mount. Hold the Toolhead in place while removing the
Engraver tensioning spring mount.
4. Using a 5/32 in. Allen wrench, remove the two Toolhead
mounting screws located at the center of the Toolhead
assembly. Bend-Tech recommends enlisting a helper to
secure the Toolhead during this process.
5. With the Toolhead removed, loosen the four Toolhead
mount plate screws roughly one full turn.
