Then check the rollers for smooth
running over the entire length of
the guideway.
Depending upon your operating

Machine Sizes 76, 92, 115, 132,
168 (Fig. 26)
For these machine sizes, the
backgauge is moved by an acme
thread leadscrew 1. The cutting
positions are always approached
in forward direction. The existing
backlash in the thread is compen-
sated by a compression spring 2
which permanently and firmly
presses nut 3 fixed to the back-
gauge against the driving flank of
the leadscrew via nut 4 axially
movable but locked against twist-
ing. This flank contact, particu-
larly at the positioning or braking
phase, is not discontinued. Depending upon the operating
conditions, the acme thread
leadscrew should, as applicable
to the backgauge guide assem-
bly, be cleand with white spirit
and be greased according to the
specified lubrication cycle once
per year.
Refer to "Lubrication" in the Oper-
ating Instructions manu-al, or to
the lubrication chart on the back
of the machine.

Machine Sizes 168 (Fig. 25)
Backgauge 1 is guided by a car-
riage 2 which, run on rollers, moves
along a profile guideway beam 3
fitted over the cutting table.
If you find any play on the back-
gauge check setting screws 4 on
the side of the backgauge for
tightness and proper locking. Re-
tighten, if required. Refer to
"Adjusting Square Cutting"in the
Operating Instructions manual.
Around the horizontal axis, the
carriage is supported by three
fixed rollers 5 and one eccentric-
ally adjustable roller above the
guideway beam and by four ec-
centrically adjustable rollers 6
beneath.
Around the vertical axis, the
carriage is secured against dis-
tortion by two fixed rollers 5 on the
right and two eccentrically
adjustable rollers 6 on the left.
If some play should occur after a
longer period of operation, you
can use the eccentric rollers to
eliminate it.
For this purpose, slacken outer
nut 7 and gently rotate eccentric
pin 8 until the roller gets into
contact with the guideway. Re-
tighten the nut.
