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.
The bag of hardware is packed in the
plastic bag containing the owner’s
manual.
To assemble your REDMAX
Tiller/Cultivator, you’ll need two 7/16"
wrenches or two adjustable wrenches.
We suggest that you install all nuts and
bolts only “finger tight” — that is, onehalf to one full turn — until you’ve
completed assembly. The nuts are self
locking, but you must use a wrench
to tighten them completely.

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.
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.

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.

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.
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.
