Touch.Control system.
The Touch-Control system is ready to oper-
ate whenever the engine is running. You will
receive the maximum of satisfactory service
by closely adhering to the following simple pre-
cautions and service operations.
The control lever ('Ilust. 13) gives the operator
complete, instantaneous and effortless control
of all the direct-connected equipment operating
adjustments. The use of the lever will depend
on the type of equipment mounted on or pulled
by the tractor. Complete instructions for oper-
ating the lever are included in the Owner's or
Operator's Manual furnished with the equip-
ment. General instructions for operating the
lever are given below.
The importance of keeping the system free
from all dirt, grit, and other foreign matter
cannot be stressed too strongly. Keep the
Touch-Control fluid reservoir, pipe lines, and
pump as clean as possible at all times. The
same care must be given to the cylinder, hose
lines, and connections. As an added precaution
against the entry of dirt into the system, the
reservoir is constructed without an air vent.
Sufficient air space is allowed above the fluid
level to compensate for the pressure changes
occuring during the operation of the system.
As a result a small amount of pressure may
be found in the reservoir upon removing the
filler plug when checking the fluid level.
The control lever quadrant is provided with
a pair of adjustable Touch-Control lever stops.
The front stop when set in a given position
will limit the travel of the control lever and
prevent the equipment from being raised above
the desired height.
The rear stop is used to point out the posi-
tion where the control lever should be each
time the equipm ent is lowered to maintain a
uniform working depth. Note: Always keep the Touch-Control lever
or levers in the rearward position (toward
tractor seat) when the tractor or the Touch-
Control system is not being actively used.
This places the piston in the retracted position,
preventing exposure to any moisture which
may have conden~ed in the leather dust boot.
To lower the equipment, move the control
lever back until the equipment has reached the
desired working depth; then move the rear stop
to this position and tighten in place.
