SECTION 2
CONTROLS AND TRELIMINARY CHECKS
2-1. CONTROLS
The controls on Model 1850 Rotary Tiller are the
control lever and throttle control.
a. The Control Lever
The Control Lever is released from Neutral by mov
ing it to the right and allowing the spring tension to
pull the control lever into one ot the tour forward
speeds. See Figure 2-1.
NOTE
Number 1 position is the slowest tine
rotation speed and number 4 is the
fastest.
Pulling the control lever backwards into the Reverse
position reverses the direction of tine rotation.
b. The Throttle Control
The throttle control actuates the butterfly in the car
buretor and may be set at stop, slow, fast or choke to
control the speed of the engine.
NOTE
Always check the throttle cable at the
engine end for a tight connection.
To stop the engine, push the throttle control all the
way in. To operate the choke, pull the throttle control
all the way out. See Figure 2-1.
c. The Depth Bar
The depth bar is used to prevent the tiller from run
ning on top of the ground instead of tilling. The deep
er you set the depth bar, the deeper you will till. Tilling
depth is from 0 to 8-inc'hes. See Figure 2-2.
FIGURE 2-1. CONTROLS
FIGURE 2-2. DEPTH BAR
2-1
2-2. WHEEL ADJUSTMENT
The wheel height can be adjusted by removing the
long clevis pin on the wheel hanger and raising or
lowering the setting. The higher the setting the deeper
the tilling depth. See Figure 2-3.
NOTE
Pick a height that places the handles in
b. Gasoline
Remove the gas cap and fill the tank with FRESH
REGULAR GASOLINE. If the gasoline has been in a
metal can for a long period, throw it away and use
fresh gasoline.
FIGURE 2-3. WHEEL HEIGHT ADJUSTMENT
2-3. CHECKING OIL, GASOLINE, AND GEAR CASE
NOTE
When packaged for shipment the ma
chine contains no oil or gasoline. Before
starting the engine, oil must be added
to the engine crankcase and gasoline
to the tank. DO NOT mix oil with gaso
line.
a. on
With the tiller on level ground, remove the oil filler
plug and pour 2% pints of good quality, SAE 30 type
MS engine oil into the crankcase. Replace the oil filler
plug.
The chain case is sealed and requires no further
lubrication unless the chain case is disassembled for
repair.

SECTION 3
OPERATINC INSTRUCTIONS
3-1. STARTING THE ENGINE
Step 1. With the tiller set on level ground, set the
control lever in NEUTRAL.
Step 2. Set the throttle control to CHOKE.
Step 3. As illustrated in figure 3-1, grasp the recoil
starter handle, pull out sharply, and hold
it in the out position. (Do not let cord snap
back.)
3-2. STOPPING THE ENGINE
To stop the engine, push the throttle control all the
way in to the STOP position. See Figure 2-1. When the
throttle control is in the STOP position, a switch blade
is activated to short-circuit the spark plug.
WHENEVER THE TILLER IS LEFT UNAT
TENDED, DISCONNECT THE SPARK
PLUG LEAD AND PLACE THE THROHLE
CONTROL IN THE STOP POSITION.
3-3. STOPPING THE TINES
Pull the control lever into the NEUTRAL position. The
tines will not rotate. See Figure 2-1.
3-4. OPERATING THE TILLER
NOTE
The cord should NOT be pulled out
more than about two feet. If engine
fails to start, allow the cord to wind
back Into the housing, then pull out
sharply again. Refer to Step 5.
Step 4. When the engine starts, gradually move
the throttle to the FAST position. After en
gine warms up (about 2 or 3 minutes) set
throttle at IDLE position.
Step 5. DO NOT OVERCHOKE ENGINE. Repeated
cranking with throttle at CHOKE position
will cause gasoline to flood the intake tube
and the engine. If, after 3 or 4 attempts,
the engine fails to start, place throttle in
FAST position, crank the engine several
times to clear out the excess fuel; and then
proceed with steps 2, 3 and 4.
Typical operation of the tiller is as follows:
Step 1. Set the clutch control to NEUTRAL.
Step 2. Start the engine as outlined in paragraph
3-1.
NOTE
To move the tiller to- the work area,
keep the depth bar in the highest posi
tion. With the throttle in the SLOW posi
tion, slowly engage the control lever
into the number 1 position and the tiller
will walk to the work area without dig
ging into the ground.
Step 3. With the clutch control in NEUTRAL, set the
depth bar in one of the lower settings.
NOTE
When several passes must be made
over a certain area, lower the depth bar
each time a pass Is made.
3-1
Step 4. Set the throttle control to FAST.
Step 5. Slowly engage the clutch control to the num
ber 1 position and the tines will begin rotat
ing, Number
mum tine speed. Tilling the ground for the
first time should be done in the number 1 or 2
position. To pulverize the soil after it has been
tilled, move the control lever to the number 3
or 4 position.
The engine must be running to move
the control lever into the faster speeds.
A downward pressure on the handles
will increase the working depth and re
duce the forward speed. An upward
pressure on the handles will reduce the
working depth and increase the for
ward speed. The type of soil and work
ing conditions will determine the actual
setting of the depth bar and the handle
pressure required.
4 position will give the maxi
NOTE
NOTE
CAUTION
If the tines stop rotating or the belt
slips, slop the engine and examine the
tine area for a rock or some object that
may be jamming the tines and prevent
them from turning. Reversing the tiller
Will usually free the object.
Step 6. To reverse the direction of rotation of the tines,
pull the control lever into the reverse position.
The control lever must be held in reverse. See
Figure 2-1.

SECTION 4
MAINTENANCE
To ensure maximum engine performance, perform
the following periodic maintenance:
a. Oil Check
Check the oil level in the crankcase before each use
of the machine and after every two hours of opration.
The oil level shall be over-flowing at the oil fill plug.
See figure 4-1.
OIL FILL PLUG
Step 1. With the machine on level ground, place a
suitable metal container under the oil drain
plug, then remove the drain plug.
Step 2. After the oil has been drained completely
from the crankcase, replace the drain plug
and tighten.

gine oil (A.P.I. class MS). Pour the oil slowly
to eliminate airlock.
4-2. CHAIN CASE LUBRICATION
The chain is permanently lubricated and requires
no further lubrication unless the case is disassembled
for repair.
If the case is disassembled, clean the chain with
kerosene, allow it to dry and work a high temperature
grease, such as Lubriplate No. 310 into the chain.
NOTE
A 4 oz container of Lubriplate No. 310
is available under part number
727-136.
OIL DRAIN
FIGURE 4-1. OIL FILL PLUG
b. Oil Change
After the first two hours of operating a new engine,
drain the oil (see figure 4-2) from the crankcase while
engine is still hot and refill crankcase with new oil;
thereafter change the oil after every 25 hours of opera
tion. This procedure ensures for minimum wear of engin parts and provides for virtually trouble-free oper
ation. To change the oil, proceed as follows:
4-3. CHAIN ADJUSTMENT
No chain adjustment is necessary.
4-4. AIR FILTER
Under normal operating conditions, the air cleaner,
located on top of the carburetor, must be serviced
after every ten hours of use. Under extremely dusty
operating conditions, the air cleaner must be serviced
after every hour of operation. See Figure 4-3.
Step 1. Remove the wing nut and cover.
Step 2. Lift off foam element from support base.
Step 3. Remove metal support tube assembly (screen
and two metal caps) from foam element by
compressing the foam element.

Step 4. a.Wash foam element in a solvent such as
kerosene or liquid detergent and wafer to
remove dirt.
b. Wrap foam in cloth and squeeze dry.
c. Saturate foam in engine oil, then squeeze
out excess oil.
NOTE
Belt tension is automatically main
tained on the forward and reverse drive
belts by idlers. No adjustment is neces
sary.
NOTE
Use the same oil for the air cleaner that
you use in the engine.
d. Assemble parts and fasten to the car
buretor.
FIGURE 4-3. AIR CLEANER
4-7. SPARK PLUG
The spark plug gap should be cleaned, and reset to
a 0.030-inch clearance every 25 hours of engine oper
ation (see figure 4-4). Spark plug replacement is rec
ommended at the start of each tiller season; check
engine parts list for correct plug type.
FIGURE 4-4. SPARK PLUG
4-5. CLEANING ENGINE AND TINE AREA
Any fuel or oil spilled on the tiller should be wiped
off promptly. Dirt, leaves and other debris must not be
left to accumulate around the cooling fins or the engine
or on any part of the tiller. Clean the under side of the
tine shield after each use. The dirt washs off the tine
easier if washed off immediately instead of after it
dries.
4-6. BELTS
Check that belts are free of oil or dirt. Wipe the belts
periodically with a clean rag.
4-8. GASOLINE FILTER AND SHUT-OFF VALVE.
Refer to Figure 4-5.
Step 1. Close the shut-off valve.
Step 2. Loosen the thumb screw below the bowl.
Step 3. Remove and clean the screen.

pulley.
Step 8. Reassemble with the new belts.
FIGURE 4-9. CARBURETOR ADJUSTMENT
4-n. ADJUSTING THE CARBURETOR
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature, alti
tude and load.
To Adjust Carburetor:
Turn needle valve clockwise until it just closes. See
Figure 4-9.
CAUTION
Valve may be damaged by turning it in
too far.
Now open needle valve IV2 turns counter-clockwise.
Close idle valve in same manner and open Va to %
turns. This initial adjustment will permit the engine to
be started and warmed up prior to final adjustment.
Final Adjustment;
Turn needle valve in until engine misses (lean mix
ture) then turn it out past smooth operating point until
engine runs unevenly (rich mixture). Now turn needle
valve to the mid-point between rich and lean so the en
gine runs smoothly.
Hold throttle at idle position and set idle speed ad
justing screw until fast idle is obtained (1750 RPM).
Hold throttle in idle position and turn idle valve in
(lean) and out (rich) until engine idles smoothly. Then
reset idle speed adjusting screw so that engine idles
at 1750 RPM. Release throttle—engine should accel
erate without hesitation or sputtering. If engine does
not accelerate properly, the carburetor should be re
adjusted to a slightly richer mixture.
4-12. ADJUSTING CARBURETOR CHOKE
Proper choke and stop switch operation is depend
ent upon proper adjustment of remote controls on the
powered equipment.
To Check The Operation Of The Choke:
Step 1. Remove the air cleaner.
Step 2. Pull the throttle control all the way out to the
CHOKE position. See Figure 2-1. The choke
should be closed.
Step 3. The engine should shut off when the throttle
control is all the way in. (STOP position.)
To Adjust;
Place remote control lever on equipment in FAST
(high speed) position. Loosen control casing clamp
screw "B." Move control casing "A" and wire until lever
"D" touches choke operating link at "C." Tighten cas
ing clamp screw "B." Replace air cleaner. See Figure
4-10.

4-14. OFF-SEASON STORAGE
/■
If the machine is to be inoperative for a period long
er than 30 days, the following precautions are recom
mended;
Step 1. Working outdoors, drain all fuel from the
fuel tank. Use a clean dry cloth to absorb
the small amount of fuel remaining in the
tank, then run the engine until all fuel in
carburetor is exliausted.
|W\RNIN^
DO NOT DRAIN FUEL WHILE SMOKING
OR IF NEAR AN OPEN FIRE.
4-13. MAGNETO AND SPARK PLUG CHECK
WHENEVER CHECKING THE MAGNETO
OR THE SPARK PLUG FOR AN ELECTRI
CAL SPAR.K, USE INSULATED PLIERS TO
HOLD THE SPARK PLUG WIRE OR THE
SPARK PLUG,
a. Magneto Check
Step 1. Disconnect the spark plug wire from the
spark plug, and place throttle control lever in
CHOKE or FAST position.
Step 2. Drain all the oil from the crankcase (this
should be done after the engine has been
operated and is still warm) and refill the
crankcase with clean new oil.
Step 3. Disconnect the spark plug wire and remove
the spark plug from the cylinder. Pour
about six drops of engine oil into the cylin
der, and then pull the recoil starter several
times to spread the oil on the cylinder wall.
Replace the spark plug, but DO NOT con
nect the wire.
Step 4. Clean the engine and the entire tiller thor
oughly.
Step 5. Lubricate the gear cane an indicated in par
agraph 4-2.
Step 6. Wipe tines with oiled rag to prevent rust.
Step 2. Using insulated pliers, hold the wire close
('/4-inch distance) to engine block or cylin
der, then crank the engine several times. A
spark should jump from the wire to the
block or cylinder; if a spark does not occur,
check the wire and the magneto.
b. Spark Plug Check
Step 1. Remove spark plug from cylinder but leave
the wire connected, and set throttle at
CHOKE or FAST position.
Step 2. Using insulated pliers, hold the metal side
of the spark plug in contact with the engine
block, and crank the engine several times.
The spark should jump the gap between
the center and side electrode in the plug.
Step 3. If a spark does not occur, check the elec
trode gap and repeat step 2. If no spark
occurs, replace the plug.
