HOW TO OPERATE THE POWER FEED ATIGIII'
HOW TO INSTALL THE DRIVE UNIT
1 Move the table to the extreme left-hand position.
2 Slide the bearing face onto the lead-screw.
3 Slide the adaptor onto the bearing face.
4 Secure it to the end of the table with the existing cap-screws.
5. Slide the power-feed onto the bearrng-face.
6 Secure it to the adaptor with the cap-screw provided.
HOW TO INSTALL THE BEVEL GEAR
1 . Press and turn the bevel-gear (Part No. A-0100-03) manually against the gear (Part No.
A-0106) at the bottom of the face of the power-feed and check the clearance between
the two parts
2 Leave the clearance between the two as small as possible, if there is some clearance
left, put the shims one by one until the proper clearance rs set.
HOW TO INSTALL THE DIAL AND THE HANDCRANK
1 After the proper backlash was set (as shown in the sketch on Page 2), adjust the dial
to obtain 0 005 spacing between the dial and the face of the power-feed to keep the
chips from entering the gear train Use the two solid and two laminated washers pro-
vided to accomplish 0 005 spacing Use also the shims as required.
2 ln the following sequence, put on the dial locking-nut, place key in shaft, slide the hand-
wheel in place, add the washer and locking-nut, and tighten the locking-nut.
HOW TO INSTALL THE LIMIT.SWITCH
1. Undo and remove the standard table stop-pieces, replace them with the stop-pieces
provided Put standard stops back in position to prevent feed-stops from being set
beyond the extreme tabletravel.
2. Undo and remove the two cap-screws holding the T-shaped table-stop bracket. Retain
it to act as a positive stop Where required for manual operation
3. Place the short spacers into the counterbored holes in the T-stop and place the limit-
switch on the spacers and locate them on the table using two 3/8 - 16 x 1 inch socket
head cap-screws.
4 Engage the limit-switch (0,4) inch before the mechanical stop to allow for coasting of
the table in a proper operation Grind the T-stops to obtain proper operation if they are
not symmetrical.
5. Secure the limit-switch cord using the clamp provided Attach it to the right-hand side
of the chip scraper with the screw provided.
