making sure the hole for the wire end is opposite the cable adjuster. (See arrow.)
b. Once the throttle wire is attached to the carburetor, locate the other end of the throttle wire and
insert the wire end into the throttle lever hole. While pulling on the throttle wire (outer part)
insert the throttle wire sleeve -into the hole in the throttle lever.
CONNECTING THE THROTTLE LINKAGE
1. Fuel
Fuel for this engine requires a mix of leaded or
unleaded gasoline and 2 cycle engine oil. Never
operate the weeder with unmixed or straight
gasoline as it will cause rapid and permanent
damage to the engine. Mix your gasoline with a
high quality 2-cycle oil that is made to mix at one
specific ratio of 50:1. We recommend that you select
a 2 cycle oil that meets or exceeds FC requirements.
OPERATING INSTRUCTIONS
CAUTION
Do not use gasohol or gasoline that contains alcohol. Always use fresh gasoline. Never
attempt to mix the gasoline and oil in the fuel tank of the engine. Always mix your gasoline
in a clean gasoline container. Once mixed, shake the container vigorously so the oil mixes
with the gasoline.

NOTE. Fig. 11 shows the location of the operating controls of your WEEDER. For your safety,
we strongly recommend that you become familiar with their functions before using the machine.
WARNING- KEEP ARMS AND LEGS AWAY FROM ROTATING TINES. ROTATING
TINES CAN CAUSE INJURY.
a. (FIG. 11) Throttle lever (1) controls the engine speed and tine rotation. Your E-Z Tiger is
equipped with a centrifugal clutch that engages the tine drive system when the engine speed
is increased. When the throttle lever is released, the engine speed slows down, and the tines
will automatically stop.
b. (FIG. 11A) Stop switch (2) has two positions, one allowing the engine to run, the other shutting
it off immediately.
c. (FIG. 11A) Start button (3) is used to activate the built-in starter motor, which starts the engine.
d. (FIG. 11B) Priming bulb (4), when pressed, delivers fuel from the tank to the carburetor. Use
priming bulb for cold starts or if engine ever runs completely our of fuel.
e. (FIG. IIB) Fuel injection button (5) forces fuel from the carburetor to the combustion chamber for
cold starts. Used after carburetor is primed.
OPERATING CONTROLS
Before Starting
1. Fill the fuel tank (to ºî to ½î inch below bottom of fill neck) with freshly mixed fuel. Replace tank
cap. Never use fuel mix that may be stale from long periods of storage.
NOTE: The engine will only start when the "stop switch" is in the "on" position.
Cold Starting
(FIG. 11 B) Depress the priming bulb (4) several times until the fuel flows through the bulb into the
carburetor. Depress the fuel
injection button (5) ONCE, which transfers the fuel from the carburetor to the combustion chamber.
Turn the stop switch (2) to the "on position" and press the "start button" (3).
CAUTION: Do not depress the start button for more than 10 seconds continuously, as this will
cause premature power drainage of the batteries. Warm the engine by running at idle speed for
2 to 3 minutes.
Warm Starting
(FIG. 11) When the engine is warmed up, it is not necessary to depress the priming bulb and fuel
injection button. Doing this would cause the engine to flood and make starting difficult. The
correct procedure is to simply rotate the stop switch (2) to the "on position" and press the "start
button" (3).
OPERATING PROCEDURES

9
If The Engine Does Not Start
1. If the engine starts but does not continue to run, repeat steps under Cold Starting.
2. If the engine cranks but does not fire, squeeze the throttle lever and repeat steps under
Warm Starting.
CAUTION!
With the throttle lever depressed, the engine will run at a high enough RPM to turn the tines.
This could propel the unit forward. In this case, tilt the unit back onto the stabilizer bar in order
to raise the tines off the ground!
3. If the starter does not make any noise when the button is pushed, either the stop switch isn't
in the "on" position or the batteries need to be charged. Repeat charging steps on p. 8.
4. If your WEEDER is equipped with the optional recoil starter, follow the same steps as above
except pull the recoil starter handle briskly instead of pressing the start button.
5. NOTE: When the engine stalls from lack of fuel, repeat the "Cold Starting" procedures.
Stopping The Engine
(FIG. 11 & 11A) Decrease the engine speed by releasing the throttle lever (1), then turn the stop
switch (2) to the "OFF" position.
USING WEEDER FOR THE FIRST TIME
a) With a firm grip on the handles, squeeze the throttle lever against the hand grip. As the tines
make contact with the ground, hold the unit back so that the tines begin to dig. If the tilling
depth is not correct (too high or too low) the stabilizer bar may be adjusted as follows:
b) Move the STOP switch to the OFF position and remove the spark plug cap. CAUTION: Never
make any adjustments to the stabilizer bar, engine, or tines while the engine is running.
c) Remove the snap pin and clevis pin securing the stabilizer bar (see FIG. 9). Adjust the stabilizer
bar up or down according to the desired depth. NOTE: Move the stabilizer bar up for a more
shallow cut or downward for a deeper cut. Reinstall the clevis pin and secure with the snap pin.
d) Start the engine and recheck the depth.
If the depth is still unsuitable, repeat the above steps.

MAINTENANCE
FIG.13
1. (FIG. 13) Air Cleaner ñ The air cleaner elements must be removed and cleaned every twentyfive
hours or at the beginning of each season. More frequent cleaning is recommended under
very dusty conditions. Thoroughly wash the elements in liquid detergent and water. Press the
elements in a rag until they are completely dry, saturate them in 2-cycle oil or the equivalent.
Squeeze the elements to distribute the oil and to remove any excess oil. Replace elements and
install cover.
2. (FIG. 14) Spark Plug - Clean and re-gap the spark plug after every twenty-five hours of operation.
Before removing plug clean around plug base to prevent foreign material from entering the
cylinder when the plug is removed. Set spark plug gap at .023 in. or 0.6mm.

3. (FIGS. 15 & 16) Muffler/Exhaust Port/Cylinder
- At the end of each season (or after 25 hours
of use) the muffler must be removed and
cleaned to prevent carbon accumulation. At
the same time, the exhaust port should be
cleaned. After removing the muffler, crank the
engine over until the piston completely covers
the exhaust port. This will prevent any foreign
material from entering the engine. Now
clean the exhaust port using a wood scraper
only (FIG. 16). At the same time, the cylinder
cooling fins should be inspected and cleaned.
If debris is collected in the cooling fins, the
engine will run hot and this could result in
serious engine damage. Use a wood scraper
for cleaning the cylinder cooling fins (FIG. 15).
FIG.17
FIG.15 FIG.16

CAUTION: Before making any inspections or repairs recommended in this manual, first make
sure the ìstopî switch is in the off position and the spark plug cap is removed. These steps will
prevent accidental starting which could result in injury.
4. (FIG. 17) Tine Shaft/Gear Case - The tine shaft should be thoroughly cleaned and oiled with
a multi-purpose oil after every twenty-five hours of operation. The tine shaft should also be
lubricated prior to storage. Every 25 hours and/or at the beginning of each season, the gear
case should be filled with grease. Remove the gear case cover by removing four screws (1) and
the bolt (2). Fill the gear case with a lithium based multipurpose grease. Insert grease rube
nipple into bolt hole of gear case. Squeeze tube until grease is level with the gear case gasket
surface. Reinstall gear case cover with gasket and tighten bolts securely. Reinstall bolt with
gasket and tighten securely.

5. General Maintenance Items - Good
preventative maintenance habits will prolong
the life of your E-Z Tiller. We recommend the
following checks after each use: check screws,
nuts, and bolts for tightness; check fuel lines
and connections for leaks; inspect and clean
fender, tines, and the gear case. (Note: When
cleaning, avoid splashing water on the engine
and stop switch.)
6. Tine Replacement - If rocks or other debris
become lodged in tines, immediately stop the
engine and clean. CAUTION: Before cleaning,
make sure the stop switch is in the off position
and the spark plug cap is removed. This will
prevent accidental starting. DANGER- Tines
are self-sharpening and will become quite
sharp. Handle carefully. Tines will wear fairly
evenly. If tines are being replaced because of wear, we recommend that all four tines are replaced
at the same time. Refer to p. 7 for installation procedure.
7. (FIG. 18) Carburetor Idle Adjustment - The carburetor has been pre-adjusted at the factory and
normally will not require further adjustment If the engine does not run smoothly at idle speed,
first clean the air cleaner element, fuel filter and check fuel lines. If they are okay, adjust the
carburetor as follows.
a) Start the engine and allow it to warm up for five minutes.
b) Turn the idle speed adjustment screw (1) clockwise or counterclockwise (clockwise increases
engine speed, counterclockwise decreases engine speed) to achieve the correct idling speed.
NOTE: If the engine speed is too high, the tines will rotate. If the engine speed is too low, the
engine will stall.
NOTE: A stiff throttle wire may cause high idling speed. Oil/spray the wire when needed. If the
wire is still stiff, it may need to be replaced.
