II. How to Assemble Lower Handles  
To identify part numbers, see page 8.  
1. Use the protective cardboard sleeve to stabilize your  
Tiller/Cultivator. Stand the engine assembly up.  
2. Lay the handle parts within easy reach. You’ll need the transmission  
bracket (#47) and one of the lower handles (#6). Note that the lower  
handles have a short leg on one end. (Picture 1)  
3. Fit the transmission bracket along the outside of the short leg. Line  
up the holes on the clamp and the leg.  
Picture 1  
Picture 2  
Picture 3  
Picture 4  
4. Using one of the two 3 1/4" bolts (#54), slide it through the hole of  
the transmission bracket (#47) and lower handle (#6) closest to the  
elbow. (Picture 2) The fit will be tight.  
5. Now slide the bolt completely through the second lower handle and  
transmission bracket. (Picture 2) Add a nut (#53) and tighten finger  
tight.  
6. Locate the worm-gear housing. It starts just above — and extends  
down through — the Tiller/Cultivator’s red fender. You’ll notice that  
there’s a recessed channel on either side of the housing’s top.  
7. Take the lower handles that you’ve just put together. Slide them into  
the two recessed channels.  
Make sure you insert them from the rear of the Tiller/Cultivator  
(gasoline tank faces away from the operator) . . . so that the bolt fits  
along the back of the housing.  
8. Slide the second 3 1/4" bolt through the second hole in the short  
legs. Add a nut (#53) and tighten finger tight. (Picture 4)  
NOTE: THE NUTS ARE SELF  
LOCKING, BUT YOU MUST  
USE A WRENCH TO TIGHTEN  
THEM COMPLETELY.

How to Assemble Upper Handles and Plastic Carrying Handle  
1. Lightly squeeze the lower handles (#3) toward one another so that they line  
up with the two smaller holes on the carrying handle (#29). Then slide the  
carrying handle over and down the lower handles. It will rest about four to  
six inches above the engine. (Picture 1)  
2. Gently pull the lower handles out to their original position.  
3. Attach the upper handle assembly (#1) – the handle with the throttle cable  
and ground wire – onto the right handle, and secure with the handle knob  
(#40) and 1 round head bolt (#39) (Picture 2). Be sure you have proper  
throttle movements and that the throttle cable is not wrapped or twisted  
around the handle bar. Squeeze trigger and let go. The triangle must click  
in both directions. If there is any doubt, remove air filter and visually check  
that the throttle triangle hits both the idle screw and the full open stop. THIS  
MUST BE DONE BEFORE STARTING THE ENGINE.  
Picture 1  
Picture 2  
Picture 3  
Picture 4  
4. Follow the same steps to install the left upper handle onto the other lower  
handle. (Picture 3)  
5. Use the clip (#6) to secure the throttle cable and wire in place on the lower  
handle. (Picture 4)  
6. Now install the Handle Brace. Line it up with the holes on the upper handles.  
Then insert a Cap Screw (#34) and a Lock Nut (#35) on either side (Picture 5)  
7. Use a wrench to tighten Cap Screws and Lock Nuts.  
8. Now use wrench to tighten all nuts and bolts firmly and securely.  
IMPORTANT NOTE:  
Make sure you have installed the handles properly. When you stand behind  
your Tiller/Cultivator, holding the handles, gasoline tank should be in front of  
the unit.  
Assembling the Tines for Tilling  
1. Remove the cardboard from around your Tiller/Cultivator’s base.  
2. Slide the tines onto the axle shafts. The “D” hole goes on the outside.  
3. Make sure you’ve installed the tines properly for cultivating. Liken  
the tines to your fingers. When your palm faces the ground, your  
fingers curl down. Stand behind the Tiller/Cultivator and hold your  
hand next to the tines. Do the tine blades curl down, as your fingers  
do? If so, they are in the tilling position. (To switch to the cultivating  
position, see page 16.)  
4. To secure each tine to the axle,  
insert a tine retaining pin.  
IMPORTANT NOTE:  
Before you use your REDMAX  
Tiller/Cultivator, read the Safety  
Rules & Warnings on pages 4-7.

Fuel Mix  
Your REDMAX Tiller/Cultivator is powered by a  
commercial two stroke, air cooled engine which  
requires a fuel mixture of gasoline and lubricating oil.  
Need pre-measured engine oil? Contact your local  
authorized REDMAX dealer.  
Remember …  
Use a mixture of 50 parts unleaded regular gasoline  
and 1 part two-stroke oil (50:1.) Make sure to use  
gasoline with a minimum octane number of 90 ROZ  
(USA/Canada: pump octant Min. 87)  
• Always mix two-cycle oil with gasoline before  
fueling your Tiller/Cultivator. Never, ever run your  
Tiller/Cultivator on gasoline alone. This will ruin  
your engine and void all warranties.  
The REDMAX engines are lubricated by oil specially  
formulated for air-cooled 2-cycle gasoline engine use.  
If REDMAX oil is not available, use an anti-oxidant  
added quality oil expressly labeled for air-cooled 2  
cycle-engine use. (JASO FC GRADE OIL or ISO  
EGC GRADE)  
• Always use a clean gas can and always use  
unleaded gas.  
• Never try to mix the oil and gasoline in the engine  
fuel tank.  
• Always mix oil and gas in the proper proportions:  
2.6 ounces (.077 liters) of two-cycle engine oil to  
one gallon (3.785 liters) of unleaded gasoline.  
Recommended mixing ratio  
Gasoline 50: Oil 1  
Exhaust emission are controlled by the fundamental  
engine parameters and components (eq., carburators,  
ignition timing and port timing) without addition of  
any major hardware or the introduction of an inert  
material during combustion.  
• Gasohol - It can cause deterioration of rubber  
and/or plastic parts and disruption of  
engine lubrication.  
• Oil for 4-cycle engine use or water coded 2-cycle  
engine use - it can cause spark plug fouling,  
exhaust port blocking, or piston ring sticking.  
How to mix fuel:  
1. Pour 1/2 of the gasoline into a safe container. Do  
not mix the fuel and oil in the engine fuel tank.  
WARNING  
DANGER  
2. Add 2.6 ounces (.077 liters) of two-cycle engine  
oil to the gasoline and mix. Then add the rest of  
the gasoline.  
FUEL IS EXTREMELY FLAMMABLE. HANDLE IT  
WITH CARE. KEEP AWAY FROM IGNITION  
SOURCES. DO NOT SMOKE WHILE FUELING  
YOUR EQUIPMENT.  
3. Screw the cap onto the gasoline can. Then swirl  
the can to blend the oil and gas.  
IMPORTANT NOTE:  
Fueling the unit:  
Do Not use old or stale oil/gasoline mixture.  
Always use the proper oil/gasoline mixture. If you  
do not, your engine will suffer rapid, permanent  
damage. And you will void the engine warranty.  
1. Carefully pour the fuel mix into the `  
Tiller/Cultivator’s fuel tank.  
2. Put fuel into the fuel tank to 80% of the  
full capacity.  
3. Fasten the fuel cap securely and wipe up any fuel  
spillage around the unit.

Starting Instructions  
Starting Your Tiller/Cultivator for the First Time  
1. Fill the fuel tank with the proper oil/gasoline mixture.  
(See previous section.)  
2. Hand tighten the gasoline cap just until it’s snug.  
3. Place the o/I switch into the I “start/on” position. (Picture 1)  
Picture 1  
Picture 2  
Picture 3  
Picture 4  
Picture 5  
4. Pull the choke button all the way out, to completely close the choke.  
(Picture 2)  
5. Locate the purge bulb on the upper right of the engine, in front of the  
fuel tank. (See Picture 3) It sends fuel into the carburetor, for easy  
starting. Press the purge bulb until you see fuel flow through the clear  
fuel return line. Since you’re starting “cold,” you may need to press six  
to eight times. As soon as fuel starts flowing through the clear fuel line,  
stop pressing! (Picture 3)  
6. Don’t press the throttle trigger during the starting of the engine.  
7. Pull the starter cord (Picture 4) until resistance is felt. Then give the  
recoil starter cord a few brisk pulls until the engine fires. Note: Pull the  
starter cord about 12" to 18". During cold starting, you may need to pull  
at least three or four times before the engine fires.  
NOTE: When the choke is closed, never pull the cord more than four or  
five times. Overpulling may cause flooding. Also, bear in mind that,  
when the engine fires, it only coughs or sputters, and will not run on  
choke.  
8. Push the choke button in, all the way, to open the choke. (Picture 5)  
9. Then pull the starter cord again. The engine should start and run. Let  
the engine warm up two to three minutes before using.  
Follow these steps whenever you are starting the engine “cold”, or  
when the engine has run dry and you have just added fuel. Remember,  
always use short, brisk pulls. Don’t give the cord a long, forceful yank.  
And, do not let the cord snap back into the starter housing.  
WARNING  
DANGER  
NEVER USE STARTING FLUIDS AS THEY WILL  
CAUSE PERMANENT ENGINE DAMAGE. USING  
THEM WILL VOID THE WARRANTY.  
BEFORE YOU USE THE TILLER/CULTIVATOR,

SPEED ADJUSTMENT (220 - 2300 RPM).  
Additional Information  
How to Stop the Engine  
Simply push the o/I switch into the I “stop”  
position. This will stop the engine instantly. If it  
should ever fail to do so, just pull out the choke  
button. The engine will stop at once.  
About the Choke  
The choke controls the amount of air drawn into the  
engine. Your Tiller/Cultivator will run only if the  
choke is open — that is, if the choke is pushed in.  
A Special Feature (with the idle set properly and  
the engine running)  
Even when the engine is running, the tines won’t  
turn unless you press the throttle lever on the  
handlebars. And, when you release the throttle lever,  
the tines will stop.  
WARNING  
DANGER  
IF ENGINE DOES NOT STOP WHEN SWITCH IS  
PUT IN THE STOP POSITION, RELEASE THE  
THROTTLE. ALLOW ENGINE TO IDLE.  
PUT THE TILLER/CULTIVATOR DOWN, AND  
PULL THE CHOKE BUTTON OUT TO COLD  
START (CLOSED) POSITION.  
A Tip for Extending Your Engine’s Life  
After you start the engine, let your Tiller/Cultivator  
warm up for two to three minutes before you use it.  
Then, before you put your Tiller/Cultivator away, let  
it idle for a minute to give the engine a chance to  
cool down.

What to do Just in Case  
If you follow the normal starting procedure, you  
should have no problem starting your  
Tiller/Cultivator. But, just in case you do have  
problems, here’s what to do.  
cap. Next, put the switch in the start position and  
pull the choke button out. Pull the starter cord  
three or four times until the engine coughs or  
sputters. Open the choke (push the choke button  
in) and pull the cord a few times. The engine  
should start and run.  
Make sure the start/stop switch is on “start.” You’d be  
surprised how many people forget to push the switch  
into the “start” position.  
2. If the end of the spark plug is dry, check to see if  
the fuel line is blocked. The fuel line runs from  
the fuel tank to the carburetor. Pull it off at the  
carburetor end. Fuel should drip slowly from the  
line. Wipe off any excess or spilled fuel.  
If the switch was on “stop” when you pulled the cord,  
you may have flooded the engine.  
• First, examine the spark plug. Use a 3/4" (19 mm)  
inch spark plug wrench.  
If fuel does not drip from the line, check the line  
for any bends or pinches. (Picture 3) Kinks in the  
line restrict the flow of fuel to the engine. Just  
straighten out the line. Reconnect. Then follow  
the normal starting procedure.  
• Remove the cap over the spark plug. (Picture 1)  
IMPORTANT NOTE:  
To avoid possible damage to the threads, do not try  
to remove the plug from a hot aluminum cylinder  
head.  
If fuel drips too freely, the line may be  
disconnected from the fuel filter. You’ll find the  
fuel filter inside the fuel tank. Just re-attach the  
line to the filter, and put the filter back in the tank.  
Then follow the normal starting procedure.  
• Unscrew the spark plug. (Picture 2)  
Starting a Flooded Engine

remove plug. Use a paper towel or a clean rag  
to dry the spark plug, then, with the spark  
plug out of the engine, pull the starter cord  
several times. Shake the fuel out of the inside of  
the plug and air dry. Next, replace the spark  
plug. Use the wrench to tighten it and replace the

Here’s Another Way to Start your REDMAX  
Tiller/Cultivator  
6. After the engine sputters, push the choke button in.  
Then pull the starter cord. The engine should start  
and run.  
If you follow the steps above and your engine still  
won’t start, try this:  
7. If the engine still does not start, repeat steps 2  
through 6.  
1. Push the switch to “start.”  
IMPORTANT NOTE:  
2. Move the choke lever to open the choke.  
3. Press the plastic bubble a few times.  
Never use starting fluids. Starting fluids will cause  
permanent engine damage. Using them will void  
the warranty.  
4. Give the starter cord a few short, quick pulls. The  
engine should start and run.  
IMPORTANT NOTE:  
5. If the engine does not start, then move the choke  
lever to close the choke. Pull the starter cord four  
to five times. The engine should sputter or cough.  
Before you use your REDMAX Tiller/Cultivator,  
read the Safety Rules & Warnings on pages 4-7.  
Tilling  
Now You’re ready to Use Your REDMAX  
Tiller/Cultivator.  
You Can Even Control Depth.  
For Deeper Cultivating:  
If you’ve seen other Tiller/Cultivators, your REDMAX  
Tiller/Cultivator may surprise you. It tills best when you  
pull it backward! You see, when you pull your  
REDMAX Tiller/Cultivator backward, you give extra  
resistance to the tines, so they dig deeper.  
Move your Tiller/Cultivator slowly back and forth, as  
you would a vacuum cleaner. Work the same area over  
and over until you’ve dug to your desired depth.  
For Shallow Cultivating:  
Switch the tines to the cultivating position. (See page 16  
to learn how.) Then move your Tiller/Cultivator quickly  
over your soil surface.  
What’s more when you go backward, you erase your  
footprints, So your soil stays light and fluffy. With other  
Tiller/Cultivators, by contrast, you walk right over the  
soil you’ve just cultivated, packing it down, so it’s less  
plantable.  
For Big Weeds or Tough Roots:  
Let your Tiller/Cultivator rock back and forth over the  
tough spot, until the tines slice through the weed or root.  
Run Your REDMAX Tiller/Cultivator like a Vacuum  
Cleaner.  
Place your Tiller/Cultivator at the head of the row or  
area you want to cultivate. Start it up. Then use an easy  
rocking motion. First, pull your Tiller/Cultivator  
backward. Then use an easy rocking motion. Again, pull  
your Tiller/Cultivator backward. Then, let it move  
forward just a little bit. Then pull it backward again.  
This will help you cultivate deeper.  
WARNING  
DANGER  
THE OPERATOR OF THIS TILLER/CULTIVATOR IS  
RESPONSIBLE FOR ACCIDENTS OR HAZARDS  
OCCURRING TO HIMSELF, OTHER PEOPLE,  
OR THEIR PROPERTY.  
Keep repeating these steps until you’ve tilled an entire  
row. Start again on the next row. It’s much like running a  
vacuum cleaner! (Picture 2)

How to Switch From Tilling to Cultivating Position  
1. Make sure your Tiller/Cultivator is off.  
2. Remove the retaining pins from the tines.  
3. Remove the tines from the axle.  
4. Place the right-side tine onto the left-side axle. Place the left side  
tine onto the right-side axle. The “D” hole should be to the outside.  
5. Here is how to make sure you’ve installed the tines properly. Stand  
behind the Tiller/Cultivator and hold your hand, palm up, next to the  
tines. Do the tine points curl up, as your fingers do? If so, they are in  
the correct cultivating position.  
6. Reinsert the pins.

Got tough weeds? Lighten your pressure on the throttle to slow your  
Tiller/Cultivator down. Then work back and forth until your  
Tiller/Cultivator chops up the weeds. It’s easy and effective!  
Remember, any Tiller/Cultivator will tangle in tall grass, stringy vines, or  
super-big weeds. So, if you have a “backyard jungle,” first use a knife,  
pruner, or brush cutter to chop up the overgrowth. If the tines become  
tangled anyway, turn the engine off completely before trying to clear  
them.

How to Check, Clean and Change the Air Filter  
Check the air filter every 25 hours of use or more frequently if used  
under dusty conditions. A clogged air filter may increase fuel  
consumption while cutting down the engine power. Never operate the  
blower without the air filter or with a deformed filter element because  
unfiltered dusty air will quickly ruin the engine.  
Cleaning air filter  
1. Remove the air cleaner cover by pulling the tab on side and take out  
the 2 filter element.  
Picture 1  
2. Use neutral detergent and warm water to clean the filter elements.  
After cleaning, air dry the element completely and moisten with a  
small amount of motor oil.  
3. Place the filter element into the air cleaner housing and press the  
cover against the housing until it clicks.  
Idle Speed Adjustment  
1. Warm up engine before adjusting idle speed.  
2. The idle speed adjustment screw controls the throttle opening at idle  
position.  
Picture 2  
3. When the engine tends to stop frequently at idling mode, turn the  
adjusting screw clock wise.  
4. If the tines continue to rotate after releasing the trigger, turn the  
adjusting screw counter-clockwise.  
Clear Blockages From the Fuel Line & Filter  
After you’ve used your Tiller/Cultivator for a few seasons, check for  
blockages in the fuel tank and fuel filter. Such blockages can keep your  
Tiller/Cultivator from starting.  
Clear any blockages you see in the tank, fuel filter, or fuel line.  
Remember: The fuel filter is located inside the tank. (See Picture 3)  
Then use the normal starting procedure to start your Tiller/Cultivator.  
Picture 3  
Spark Plug  
1. Starting failure and mis-firing are often caused by a fouled spark  
plug. Clean the spark plug and check the that the plug gap is in the  
correct range. (Picture 4) (.025., 0.65 mm)  
2. CAUTION: Do not over tighten the spark plug. To install the spark  
plug first turn the plug until it is finger tight, then tighten it a quarter  
turn more with a socket wrench.  
3. For a replacement plug, use the correct type specified by RedMax.  
The replacement plug is Champion RCJ6Y (5602-73110)

Maintenance cont.  
How to Reseat the Flange  
At some point, you may find that the tines won’t turn when you press  
the throttle. This may mean the engine isn’t sitting all the way down on  
the worm-gear housing.  
Perhaps you’ve been using your Tiller/Cultivator for several years. The  
flange bolt (Key #22) may have come loose and lifted the engine up.  
If this happened you’ll notice a gap between the bottom of the engine  
flange (Key #24) and the top of the wormgear housing. (Picture 1)  
To fix this, loosen the flange bolt. Take the engine off the wormgear  
housing. Notice the hex head on top of the drive shaft (Key #28). Inside  
the flange housing, you’ll find the clutch drum (Key #25). Make sure  
the hex head lines up with the clutch drum inside the flange housing.  
Picture 1  
Then put the engine back on the wormgear housing. Make sure the  
plastic carrying handle is not under the fuel tank.  
If you’ve followed these steps properly, there will be no gap between the  
engine flange and the wormgear housing. (Picture 2) Make sure you  
tighten the flange bolt!  
How to Check the Grease Level Inside  
the Worm-Gear Housing  
Picture 2  
When we built your REDMAX Tiller/Cultivator, we lubricated the  
worm-gear housing thoroughly.  
It is imperative that you inspect the grease level once a year. Simply  
remove the cover plate on the worm-gear housing. (Picture 1) Then  
check to make sure the grease comes almost to the top of the housing. If  
it doesn’t, add lithium #0 grease. This is the only way to add grease to  
the worm-gear housing. (Picture 3) To purchase grease, contact your  
local authorized REDMAX dealer.  
Please do not overfill. Too much grease can create pressure, which  
could cause seals to fail or the clutch to slip.

Maintenance cont.  
Muffler  
Inspect periodically, the muffler for loose fasteners,  
any damage or corrosion. If any sign of exhaust  
leakage is found, stop using the machine and have it  
repaired immediately.  
Note that failing to do so may result in the engine  
catching on fire.  
Spark Arrester  
The muffler is equipped with a spark arrester to  
prevent red hot carbon from flying out of the  
exhaust outlet. Periodically inspect and clean as  
necessary with a wire brush. In the State of  
California it is required by law (Section 4442 of the  
California Public Resources Code) to equip a spark  
arrester when a gas powered tool is used in any  
forest covered, brush covered, or grass covered  
unimproved land.

PART OF THE TILLER/CULTIVATOR.  
Never touch the cylinder, muffler, or spark plugs  
with your bare hands immediately after stopping the  
engine. The engine can become very hot when in  
operation, and doing so could result in severe burns.  
When checking the machine to make sure that it is  
okay before using it, check the area around the  
muffler and remove any debris. Failing to do so  
could cause the muffler to become overheated, and  
that this in turn could cause the engine to catch on  
fire. Always make sure that the muffler is clean and  
free of debris before use.  
Check the intake air cooling vent and the area  
around the cylinder cooling fins after every 25  
hours of use for blockage. Note that it is necessary  
to remove the engine cover in order to view the  
upper part of the cylinder.  
Procedures to be Performed After Every 100 Hours of Use  
1. Remove the muffler, insert a screwdriver into the  
vent, and wipe away any carbon buildup. Wipe  
away any carbon buildup on the muffler exhaust  
vent and cylinder exhaust port at the same time.  
Picture 2  
2. Tighten all screws, bolts, and fittings.  
3. Check to see if any oil or grease has worked its way  
in between the clutch lining and drum, and if it has,  
wipe it away using oil-free, lead-free gasoline.

Storage  
Each fall — or before you store your REDMAX  
Tiller/Cultivator for any long period — be sure to  
take these measures:  
you’ll have the parts well before the next  
gardening season starts.  
12. Store your Tiller/Cultivator — in an upright  
position — in a clean, dry place.  
1. Do not store your Tiller/Cultivator with fuel still  
in it. Even under ideal conditions, stored fuel  
containing ethanol or MTBE can start to go stale  
in 30 days. And, since stale fuel has a high gum  
content, it can clog the carburetor, this, in turn,  
will restrict fuel flow. So, when you’re ready to  
store your Tiller/Cultivator, or will not be  
using it for more than 2 weeks, drain the fuel  
tank completely.  
13. Do you have fuel left over from last season?  
Dispose of it properly. Buy fresh oil and gasoline  
next season.  
How to Prepare Your REDMAX Tiller/Cultivator  
for Restarting  
In the Spring, when you take your Tiller/Cultivator  
out of storage, remove the spark plug. Pull the starter  
cord three or four times to clean oil from the  
combustion chamber. Wipe oil from the spark plug.  
Place the spark plug back into the cylinder. Re-  
connect the spark plug wire back on the spark plug.  
Then follow the steps on pages 12 to refuel and  
restart your Tiller/Cultivator.  
2. Next, restart the engine to make sure no fuel is  
left in the carburetor. Then run the engine until it  
stops. This will prevent gum deposits, forming  
inside of the carburetor and possible engine  
damage.  
3. Disconnect spark plug wire and remove the spark  
plug. (Use a 19mm or 3/4" spark-plug wrench.)  
Pour about a teaspoon of clean, air-cooled, two-  
cycle oil through the spark-plug hole into the  
combustion chamber. Slowly pull the starter cord  
two or three times to coat the inside of the  
cylinder wall.  
Again, Check the Carburetor.  
If your Tiller/Cultivator won’t restart in the Spring  
— or if it lacks its usual power — the carburetor  
may need attention.  
Check the Spark Plug Too.  
If your Tiller/Cultivator won’t restart, or if it lacks  
full power, the spark plug may be at fault. Check to  
see if the plug is fouled with oily black deposits.  
Clean or replace it if it is.  
4. Inspect the spark plug, and, if necessary, clean it.  
If you need to replace it, buy a Champion  
RCJ6Y (5602-73110)  
5. Install the spark plug, but leave the spark plug  
wire disconnected.  
Also, check whether the center electrode is rounded  
at the end, or if the ground electrode is worn. If  
either is the case, you should replace it with a  
Champion RCJ6Y spark plug. Use a 19mm or a 3/4"  
spark-plug wrench to install it. Adjust the plug gap to  
.025 in. (0.65 mm)  
6. Clean the air filter as described on page 17.  
7. Clean dirt, grass, and other materials from the  
entire machine.  
8. Wipe the tines with oil or spray them with WD-  
40, to prevent rusting.  
To Install the spark plug first turn the plug until it is  
finger tight, then tighten it a quarter turn more with a  
socket wrench.  
9. Oil the throttle cable and all visible moving parts.  
(Do not remove the engine cover.)  
IMPORTANT NOTE:  
10. Check the grease level in the wormgear housing,  
as described on page 18.  
To avoid possible damage to the threads, do not  
try to remove the plug from a hot aluminum  
cylinder head.  
11. Order new parts to replace any that are badly  
worn or broken. Just contact your local  
authorized REDMAX dealer. But do it early, so
