the rotating wheel.

Before commencing the wheel dressing procedure be aware that a large quantity of grinding dust can be
released and it is most important that suiiable face protection and a drist mask are worn' Grinding wheels
are brittle and run at high speed inhaling grinding dust may cause some severe respiratory diseases' Treat

Remember the depth adjustment screw (75) will not directly affect tooth shape, but merely raise or lower

General Notes:
-Tt" gri"d*g process tends to leave a burr on the inside edge of the ground-surface. This is best
removed with a sharp steel edge such as a knife being drawn around the blade while still supported by the
sharpener frame, Exircise care not to damage or dull the teeth in the plocess.
+ If setting up the machine for a permanent installation, allow ready access to the underside of the
machine for ifre placement and rimoval of components such as the idler gear (B36).

.\ further benefit is obtained in bevelling the teeth as the grind marks on the tooth face and back produced

The point at which the grinding head tilts is determined by the timing between the a

* V/ith the idler gear and the grinder motor fuse removed, inch the feed button until the grinding wheel is
positioned at the point where the bevel is required.
i To* the gearlcam assembly anti clockwise by hand until the follower bearing moves
into depressed lobe of the cam. This tilts the head away from the operator. Note there is a i5' dwell on
the cam so take this into account timing. Teeth bevelled on the baci require the cam timing set so that the
head has just tilted as it reaches the top of the tooth (retarded) while teeth bevelled on the front face
require the tilt to be completed as the grinding wheel finishes the face and enters the gullet (advanced),
* insure the grinding wheel is still at ihe point where the bevel is required and the bevel cam is correctly
positioned wittr the cim follower in the depression, then move the idler gear (836) and tighten with the
iutO pu.r head screw through the slot in the rear plate so that the gear completes the gear train'
Note: The bevel cam/gear rotates anti clockwise and there is a 15" dwell. Failure to take account of this
dwell with regard to where the bevel is to be applied will result in the head being tilted in the gullet'
I
Further minor adjustment is the made by loosenin gthe2 screws retaining the cam to it's driven gear and
rotating cam until the exact timing is obtained. Retighten the cam retaining screws.
The grinding head alternatively bevels twice every three teeth and it is important to ensure that the tilt
,"qu"r.. and direction .oo"rponds to the setting sequence of the blacle. Blades are normally left - right -
straight but sometimes right -left - straight teeth are encountered. This requires the Tilt Cam to be
removed from the driven gear and inverted as described previously.
Before beginning to sharpen blades, is important that the grinding wheel is centred (as previously
described) and the head is free to rotate.
With a blade fitted to the machine and the head suitably timed for the blade (either the front or back of the
tooth to be bevelled), index the machine unril the grinding wheel has reached it's full tilt (either side) at
the appropriate point along the tooth profile and lower the grinding head until the wheel just touches the
tooth. Index the machine until the head bevels at the same point on the alternate tooth. Check the gap
distance between the wheel and the tooth to ensure the wheel is centred.
The head tilt is controlled via a push rod up the middle of the motor pivot arm. This axial motion is
transferred to tilt the head through a reciprocating worm rack engagin-e a segmented gear attached to the
head pivot. To ensure smooth operation, it is important that the backlash between the rack and the gear
is eliminated without any preloading which may cause the movement to sick. Adjusting this backlash is
achieved by rotating the eccentric bush (B6) around the motor arm (B 17). Loosen the M3x6 retaining
screw (B4) and using it as a lever, move it within the arc allowed by the slot. Moving the screw in the
slot towards the operator removes the backlash. Tighten only enough to remove excess movement and
then retighten the screw.
