handle for operator comfort.) Route the
wiring harness along the handle, plugging it
into the blade control switch, o.p.c. and
speed control switch located under the
speed control plate. There is not a specific
color code for hooking up the harness. Run
the throttle cable around the left hand side
of the engine to the throttle plate,
Place the
throttle in the full speed detent, with the
throttle wire hooked in the speed control
arm on the engine throttle plate, pull on the
conduit until the speed control arm is at
maximum speed, tighten conduit clamp.
7. At this point, you are ready to oil and fuel
the engine. With that being done, take
the unit and raise the rear wheels off the
ground so that they may free wheel.
Block the unit up securely so that you
may run the engine with no danger of it
falling from the stand. With the speed
control in the neutral position, start the
engine and run it at 3/4 to full throttle.
Using a 5/16" wrench adjust the speed
control link, to set the right hand wheel to
neutral no matter what the left hand
wheel does. With that accomplished,
lock the lock nuts into place on speed
control link. If the left hand wheel is not
neutralized use a 1/2" wrench, to break
the lock nut loose on the pump link and
adjust the rod end to neutral the left hand
wheel. After accomplishing neutral, shut
the engine off and remove the support
blocks from under the machine. With the
engine shut down, take the drive rods
and bolt them onto the main control shaft
using the 5/16" nyloc nuts provided.
Adjust the length of the rod so that the
pins in the drive levers are just a little
under center of the neutral lock on the
thumb lock. (See fig.)
8. You are ready for your test run to set the
full speed tracking. Remember to check
the air pressure in the tires. Rear wheels
should be set at 12 psi, front casters to
20 psi. Run unit at full throttle and set
control lever to the full speed setting.
The test run should be made on some
type of hard surface with the ground
being fairly level. If the machine pulls
one way in full speed, adjust the slow
side stop bolt up to speed up the slow
motor. If there is not enough adjustment
to speed up the slow motor, you may
have to lengthen the stop bolt on the fast
side. Run that machine at an
intermediate speed. If you have a
tracking problem after full speed tracking
is set, the adjustment is in the pump arm
rod end. This is remedied by adjusting
the length of the pump arm. Brake the
lock nut loose on the pump arm and
remove the bolt from the rod end that
attaches it to the link. To increase the
pump speed, shorten the pump arm. To
decrease the speed, lengthen the pump
arm. Usually about two full turns on the
pump arm rod end to speed up or slow
down is adequate. (See fig.
