(1) Set air inlet valve screw No.2 to half of maximum opening
and lock securely with lock nut No.3.
(2) Close gasoline needle valve No. 1 and re-open about one-
half turn, then adjust accurately by opening or closing as necessary
to provide correct idling and pulling.
(3) Set throttle No. 6 by small stop screw to provide proper
idle speed.
Clean dirt and water from system once each week by removing
cleaner plug from strainer No.5 and by opening drain cock No.4.
Air Cleaner
Remove dust from bottle on air cleaner when partially filled.
Remove core from air cleaner each 48 hours of service and wash
thoroughly in gasoline. When dry, dip in used motor oil, allow
to drain, and replace after cleaning air cleaner shell with gasoline.
Repairs
In making repairs, use care in eliminating dirt from all working
parts of tractor.

Clutch Adjustment
The multiple-plate oil-bathed clutch requires little adjustment
once set. Adjustment for release with dog engaged, and crutch
handle convenience, is made by clutch adjustment turnbuckle No.2.
Be sure that clutch rod pivot link No.4 works freely, but is
not loose.
The release adjustment is sometimes necessary when the handles
are adjusted for height or row clearance.
If clutch slips, remove inspection plate No. 11 and tighten clutch
spring nut to increase spring tension. Be sure to replace cotter key
in adjustment nut.
Chain Adjustment
Traction chains should be adjusted so that they have Ya" sag on
top when chain is on a level floor, and tight around the wheels-s-
when they become slack. Adjust by loosening rear axle bolts and

Drawbar Assembly
seer. above, the drawbar is made in three parts-the bottom
: clevis, No.1, the top half of clevis, No.2, and the drawbar,
Ibotto= !:.all of the clevis is fastened to the gearcase by pivot
...ee rwo !:.a.lves of the clevis are fastened loosely together by
';;~::at No.5, which works freely in a slotted hole to permit
~e:l' 0: the rwo halves of the clevis. Pins No.6 and 7 are
_'"to =ke ~e clevis rigid for use in cultivating, discing and
--g. as well as miscellaneous power jobs.

(5) Check bolts No. 13 and 14 to see that the plow-beam, No. 15,
is free to pivot on bolt No. 13 and work bolt No. 14 in slotted guide
on plow-beam clevis No. 16.
(6) Set plow in ground and adjust for depth by depth set-screw
No. 17. Adjust for a shallow cut by turning down on No. 17; adjust
for a deep cut by turning up on No. 17. Be sure to lock No. 17 in
desired position by lock nut to prevent variation.
Note: New plows are varnished and may not scour readily; if
so, use turpentine or sandpaper to cut the varnish off.
Outboard wheels come as standard equipment on all Flex-Treds
and should be used in plowing, discing, harrowing, etc., where added
traction or stability is desired.
Discing and Harrowing
-Anae"1 diSC o~oW''"fo cr.aw"S'itt'" i8 tflat-it call PTvOt' .... on the
coupler bolt provided. Use both pins No.6 and No.7 in drawbar
clevis. Do not attach to quadrant. Adjust blades for pitch and
gangs for dish by the usual method.
Harrows are provided with a tr ip handle for cleaning when
clogged with lumps or trash.
Cultivating
Fasten cultivator to drawbar rigidly, making sure that the two
alignment lugs fit into slots properly. Use quadrant holes to adjust
for depth of cultivation.
In using the cultivator, both pins No.6 and No.7 in drawbar
clevis should be in place, making a rigid drawbar. This prevents
uneven work and makes handling easier.
Planting and Digging Root Crops
In addition \.0 standard work, your Flex-Tred can be used for
planting and d.gging' potatoes or other root crops by using the
special middle-splitter plow which is listed in your catalog at $22.00.
This plow is attached by the three bolts No.9, and is aligned true
