TRAVERSE ENGAGEMENT AND RELEASE
The belt that drives the relief and spin hubs left and
right can be engaged and released by flipping the clamp
located on the bottom of the grinding head assemblies.
Moving the lever to the left will engage the belt and
moving it to the right will disengage the belt. The tip
can be adjusted if necessary to increase or decrease
the tension on the belt. See adjustments in the
service manual for more details.
THE BELT CLAMP TIP IS
ADJUSTED AT THE FACTORY TO
ALLOW THE BELT TO SLIP IF THE
HUB COMES IN CONTACT WITH
SOMETHING. CAUTION SHOULD
BE USED WHEN ADJUSTING THE
TIP. IF THE CLAMP IS OVER-
TIGHTENED, THE BELT WILL
NOT SLIP WHICH MAY CAUSE
DAMAGE TO THE MACHINE OR
REEL.

TRAVERSE PROXIMITY SWITCHES
Two movable proximity switches determine the left and
right limits of grinding head assembly. An LED on the
switch lights when the grinding head gets close to the
head of the proximity switch. The sensors are mounted
in the Proximity Brackets located on the traverse shafts.
The brackets can easily be slid along the shafts for quick
and easy travel limit adjustments. When switching from
the spin mode to the relief mode, the brackets will need
to be lifted off the shafts and snapped back on the shafts
in the proper position.
SPIN/RELIEF GRINDING HEAD
This grinder is equipped with separate spin and relief
grinding wheels. When the setup is done properly the
reel will be only need to be positioned and aligned once
for both cycles. The spin wheel is located on the right
side of the machine and is wider than the relief wheel.
Move the wheel that is not being used as far to that side
as possible to give the maximum amount of room to
setup and operate the machine. The proximity
sensors must be moved so that the wheel in use is
between the two sensors. Make sure that the wheel
that is not in use is not engaged to the drive belt.
