BLADE RITE 1750 MANUAL

3.7 Connect reel drive motor. Loosen the locking lever clamping the support rod position
and the wing knob that locks the motor to the support rod; Rotate the support rod in it’s
mounting and slide the motor up and down until the output shaft aligns with the reel drive.
Connect the “slip clutch” output to the reel with a suitable coupling.
3.8 Select the direction to drive reel down onto blade rest (down from the top) and switch on
the motor.
3.9 Adjust the “slip clutch” so that it just keeps the reel blades onto the finger so that there is
sufficent torque for a smooth index between blades. This is achieved by loosening the
locking ring and by rotating the adjusting collar at the rear of the “slip clutch” (closest to
motor/gearbox) to increase spring compression; Clockwise rotation increases torque,
counter clockwise rotation reduces it.
3.10 Traverse the grinding head, by hand, to the left and right to check that the indexing is
working (remember to pause at the r/h traverse stop to give the reel time for the next blade
to reach the rest)
3.11 Switch on the traverse motor and engage with the lever, to confirm indexing works (The
traverse automatically pauses at each end, longer at the right-hand end to allow time for
indexing). If all is ok, disengage the traverse. Traverse speed may be adjusted by means of
the potentiometer knob on the control panel.
3.12 Mark one blade as a “datum” so that it can be returned to each time.
3.13 Lower the safety guard.
Note: Before actual grinding takes place, ensure that appropriate safety wear is used (see safety
notes in section 1).
