Assembly Instructions Your REDMAX Precision Tiller/Cultivator comes partially assembled. You must install only the handlebars, the carrying handle, and the tines. This will take just a few minutes if you follow the directions. First, take all items out of the carton. But do not remove the cardboard from around the Tiller/Cultivator’s base. The list below, shows the parts that come with your Tiller/Cultivator. Check to make sure you have them.
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 4.
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.
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. 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) The REDMAX engines are lubricated by oil specially formulated for air-cooled 2-cycle gasoline engine use.
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) 4. Pull the choke button all the way out, to completely close the choke. (Picture 2) Picture 1 5. Locate the purge bulb on the upper right of the engine, in front of the fuel tank.
Starting a Warm Engine 1. Slide ignition switch to START position. 2. Move the choke lever to the Open (Run) position. 3. If there is no fuel in the clear return line, push primer bulb 3-4 times or until fuel is visible in the line. 4. Pull starter rope using short pulls, 1/2 to 2/3 of the rope length. 5. If engine fails to start in 4 pulls, use “First Time” starting procedure on page 14. 6.
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. 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. 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.
What to do Just in Case cont. Here’s Another Way to Start your REDMAX Tiller/Cultivator If you follow the steps above and your engine still won’t start, try this: 1. Push the switch to “start.” 2. Move the choke lever to open the choke. 3. Press the plastic bubble a few times. 4. Give the starter cord a few short, quick pulls. The engine should start and run. 5. If the engine does not start, then move the choke lever to close the choke. Pull the starter cord four to five times.
Cultivating 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.
Maintenance 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.
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.
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.

Storage Each fall — or before you store your REDMAX Tiller/Cultivator for any long period — be sure to take these measures: 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.
Troubleshooting Guide Case 1. Starting failure Check Probable Causes Action Fuel Tank Incorrect fuel Drain it and fill with correct fuel Fuel Filter Fuel filter is clogged Clean Carburetor Adjustment Screw Out of normal range Adjust to normal range Sparking (no spark) Spark plug is fouled/ wet Clean/ dry Plug gap is incorrect Correct (GAP: 0.6 ~ 0.7 mm) Disconnected Retighten Spark Plug Case 2. Engine starts but does not keep running/ hard re-starting.
