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.
