ASSEMBLY INSTRUCTIONS

Right hand (R.H.) and left hand (L.H.) are as observed

from the operating position.

1. Assemble chrome handles {Ref. Ncs. 8 and 24) to
the frame with four hex head cap screws %-16 x %
long and four lock washers DO NOT TIGHTEN.

2. Assemble handle panel (Ref. No. 29) to the handles
with the four carriage bolts ’/i-20x 1V4 Ig. and hex
locknuts %-20 thd. Assemble handle panel so you
can read the instructions on the handle panel from
the operating position. LIFT HANDLE UP AS YOU
TIGHTEN ALL BOLTS AND NUTS ON THE HANDLE

ASSEMBLY.

3. Move the shift lever (Ref. No. 17) on the handle
panel all the way forward into No. 5 position: Use

hole marked "26". Assemble the ferrule to the end
hole in the shift lever from the R.H. side. Screw in
the shifting rod (Ref. No. 32) into the ferrule. Move
the shift lever into the reverse (R) position. Lift the

transmission arm on the rear of the frame all the

way up. Adjust the shift rod by screwing it on or
out until the lower end fits into the transmission
arm. Secure with a cotter pin (Ref. No. 141).

4. CLUTCH GRIP. Place the threaded end of the lock*
out rod (Ref. No. 31) inside the spring. (Opposite
end of the hook.) Screw on the elastic stop not *A-2D
thread approximately to 1 inch. Hook the bent
end of the rod into the eye of the clutch grip from

the right hand side. With the clutch in the released
position, hook the spring into the hole in the link

age arm. The spring and rod should be just tight
enough so the rod is not too loose. Adjust the elastic
stop nut if necessary.

5. Chute Crank. Assemble the chute crank (Ref. No.

33) into the two holes in the handle panel being

sure the rod passes through the lock bracket (Ref.

No. 23). It may be necessary to loosen the black

CONTROLS

Auger Clutch is located on the Left Hand side of the
frame just behind the thrower housing, (Shown in the
disengaged position.) When the handle is up, the aug
er is disengaged. WARNING: Engaging auger clutch
with main clutch already engaged will damage pins
on sprocket hob assembly. Damaged pins cause hard
engagement and clutch malfunction. Do not engage or
disengage the auger clutch without first disengaging
the main clutch. Disengaging the auger clutch allows
you to drive the snow thrower to and from the work

area without the auger turning. (See figure 2.)

Shift Lever. The shift lever determines the direction
and speed forward of the drive wheels. Always re
lease the grip clutch when shifting gears. (See figure 3.)

Chute Controls. Release the lock and turn the crank
to rotate the chute. Loosen the wing nut to adjust the
deflector. (See figure 3.)

FIGURE 3.

SKID SHOES

The skid shoes on each side of the thrower are adjust

able by loosening the bolts and nuts.
