S t o r a g e
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. 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.
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.
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.
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.
9. Oil the throttle cable and all visible moving parts.
(Do not remove the engine cover.)
10. Check the grease level in the wormgear housing,
as described on page 18.
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
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.
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.
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.
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)
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.
IMPORTANT NOTE:
To avoid possible damage to the threads, do not
try to remove the plug from a hot aluminum
cylinder head.
