Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that is easy to ignite and cause a fire or explosion.
Never overlook the hazards of gasoline and always follow these precautions:
Never run the DR 2-CYCLE TILLER CULTIVATOR Engine in an enclosed area or without proper ventilation as the exhaust from
the Engine contains carbon monoxide, this is an odorless, tasteless, and deadly poisonous gas.
Store all fuel and oil in containers specifically designed and approved for this purpose and keep away from heat, open flame,
and out of the reach of children.
Mix the oil and gasoline outdoors and then fill the Fuel Tank outdoors with the Engine off; allowing the Engine to cool
completely. Do not handle gasoline if you or anyone nearby is smoking, or if you are near anything that could cause it to ignite
or explode. Replace the Fuel Tank and Fuel Container Caps securely.
If you spill gasoline, do not attempt to start the Engine. Move the machine away from the area of the spill and avoid creating
any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly
dispose of the waste.
Allow the DR 2-CYCLE TILLER CULTIVATOR Engine to cool completely before storing in any enclosure. Never store the
machine with fuel in the tank or with fuel in a container near an open flame or spark such as a water heater.
Never make adjustments or repairs with the Engine running. Before making an adjustment or repair, shut off the DR 2-CYCLE
TILLER CULTIVATOR Engine, wait five (5) minutes to cool, then disconnect the spark plug wire and keep the wire away from
the spark plug to prevent accidental starting.
Never check for an ignition spark with the Spark Plug or Spark Plug wire removed. Always use an approved spark tester.
To reduce fire hazard and keep the Engine from overheating, keep the Engine and Muffler area free of debris or any other
combustible material.
Never operate the Engine without the Muffler. Inspect the Muffler periodically and replace if necessary.
Never operate the Engine with the Air Filter or Cover over the Carburetor air intake removed, except for adjustment. Removal of
such parts could create a fire hazard. Do not use flammable solutions to clean Air Filter.
Always check Fuel Lines and fittings frequently for cracks or leaks, replace if necessary.

Chapter 3: Operating Your DR 2-CYCLE TILLER CULTIVATOR
This chapter covers the procedures for starting and stopping your new DR 2-CYCLE TILLER CULTIVATOR and discusses basic
operation features.
Before Starting the Engine
Cold Engine Start:
1. Push the Primer Bulb in and then release until it returns to its original
position (Figure 6). Repeat this process 6 times or until the Primer Hose is
full of fuel.
2. Move the Choke Lever all the way to the CHOKE position and make sure the
On/Off Switch is in the ON position (Figure 7).
3. Standing between the Handlebars, push down on the Handlebar lifting the
Tines off the ground (Figure 8). Grasp the Recoil Starter Handle with your
left hand and slowly pull until you feel resistance, then pull the cord with a
smooth accelerating motion to start the Engine. Do not let the Starter
Handle snap back against the Engine. One or two pulls usually starts the DR
2-CYCLE TILLER CULTIVATOR.
Note: If the Engine fails to start after 5-6 pulls, push the Primer Bulb 1 more time
and pull the Starter Rope again.
4. After the Engine starts, release the Throttle Lever and move your left hand to
the Handlebar position for stability. Slowly push the Choke Lever to the half
choke position with your right hand until the Engine starts to run smoother
and then all the way to the RUN position.
5. Squeeze the Throttle to the desired speed. For the best Engine performance,
do not hold the engine at full throttle while the tines are not making contact
with your working area. Running the engine at maximum throttle without
and load applied may cause engine damage.
Warm Engine Start:
1. Make sure the On/Off Switch is in the ON position (Figure 7).
2. Repeat steps 3 through 5 with the Choke in the RUN position.

Stopping the Engine
Release the Throttle Lever and turn the On/Off Switch to the OFF position
(Figure 9).
Operating Procedures
Cultivate without placing excessive body weight on the machine. The cultivator operated most efficiently under its own weight.
Allow the machine to till soil clawing its way forward. Depending on the soil type and moisture conditions, the slower the
cultivator moves across the working area, the deeper the tines will penetrate.
Make multiple passes over working area to cultivate soil effectively.
Note: This cultivator is designed to till predominately loose soil. Attempting to break hard pack soil may damage tines.
Note: The 43cc 2-cycle engine is only designed to be run under the load of tiller. Holding the engine at full throttle continuously while the
machine is not in use may cause permanent engine damage.
1. Ensure the Drag Stake and Wheel height is set to the desired position.
2. Start the machine as described in the previous section.
3. Lift Tines off the ground and operate the Throttle Lever to full speed.
4. Slowly lower the Tines into the soil as you begin walking forward to till soil.
Note: Holding back on the Handlebar will slow the forward movement to till material more thoroughly.
5. Release the Throttle Lever when you want to stop the Tiller.
6. Shut the Engine off before leaving the Tiller.
Figure 9
On/Off
Switch
The Tines Drive Clutch will transfer maximum power after about two hours of normal operation. During this break-in period,
Clutch slippage may occur and is normal.
The Tines should not rotate when the Engine is idling; if they do, contact us at www.DRpower.com for instructions.
Use the DR 2-CYCLE TILLER CULTIVATOR without placing excessive body weight on the machine. The unit operates most
efficiently with the weight of the machine itself.
Use common sense when using the machine. Learn to recognize the change in sounds when it is overloaded. Turn off the
Engine immediately if the machine becomes jammed to prevent damage to the drive system.
Never stop the Engine by moving the Choke Lever to the CHOKE position.
This could cause an Engine backfire resulting in Engine damage.

Handling and Transporting
Adjusting the Wheels and Drag Stake
Adjusting the Wheels
You can adjust the Wheels on the DR 2-CYCLE TILLER CULTIVATOR to one of
three positions (Figure 10). Use the lowest Wheel position for transporting the
machine across a smooth level surface while the Engine is not running. Use the
two higher positions for tilling in soil and to help stabilize the unit when tilling
at different depths.
1. Pull the Locking Sleeve toward the Spring until it releases from one of the
three cutouts in the Vertical Guide.
2. Slide the Wheel Set up or down to the desired position, and then release the
Locking Sleeve until it locks into one of the three cutouts in the Vertical

Adjusting the Drag Stake
The Drag Stake is used to help regulate tilling depth and control the machine
from lurching forward during operation (Figure 11). Set the Drag Stake in its
lowest position of three to provide the greatest resistance to forward motion
allowing for deeper tilling.
1. Pull the Lock Pin out of the Drag Stake Mounting Hole.
2. Position the Drag Stake to the desired depth and reinsert the Lock Pin.

Be sure to run the Engine at full Throttle.
If your DR 2-CYCLE TILLER CULTIVATOR still bounces, visit our website at
www.DRpower.com for assistance.
The tilled soil balls up
or clumps.
The ground that you are trying to till is too moist.
Prior to performing any maintenance, you must first shut off the Engine; wait five minutes to allow parts to cool and disconnect
the Spark Plug wire, keeping it away from the Spark Plug.

Daily Checklist for the DR 2-CYCLE TILLER CULTIVATOR
To help maintain your DR 2-CYCLE TILLER CULTIVATOR for optimum performance, we recommend you follow this checklist each
time you use your machine.
[ ] FUEL: Fill the Fuel Tank with a fresh unleaded gasoline/2-cycle oil mixture. See page 10.
[ ] ENGINE: It is very important to keep the Engine clean. Remove dirt and other debris from the Engine Cooling Fins. A dirty
Engine retains heat and can cause damage to internal Engine components.
[ ] HARDWARE: Check all nuts and bolts to be sure that the components are secure.
[ ] FRAME: Check all welds to be sure that the Frame is intact and secure.
[ ] TINES: Make sure that the Tine Assemblies and Tine Shield are free of accumulated debris.
[ ] ENGINE AIR FILTER: Clean engine air filter before each use to ensure optimal engine performance.
End of Season and Storage
If your DR 2-CYCLE TILLER CULTIVATOR will not be operated for more than 30 days, we recommend using a fuel stabilizer.
This will prevent sediment from gumming up the carburetor. If there is dirt or moisture in the fuel or tank, remove it by
draining the tank. Completely fill the tank with a fresh fuel mixture and add the appropriate amount of stabilizer or fuel
additive. Run the Engine for a short time to allow the additive to circulate?
Remove the Spark Plug and pour about 1 ounce of motor oil into the cylinder hole. Replace the Plug and pull the Recoil Starter
Rope until you feel strong resistance. This will coat the Piston and Cylinder Wall to prevent moisture buildup.
Clean or replace the Engine Air Filter.
Clean dirt and debris from the Engine Cylinder Head Cooling Fins, Debris Screen, and Muffler.
Clean out residual debris from the under the Tines Hood and Tine Assemblies.
Touchup all rusted or chipped paint surfaces. Sand them lightly before painting.
Be sure all Nuts, Bolts, and Screws are securely fastened.
Inspect moving parts for damage and wear; replace if necessary.
If possible, store your DR 2-CYCLE TILLER CULTIVATOR inside, but not near an open flame or spark such as found in a water
heater.
After the DR 2-CYCLE TILLER CULTIVATOR has cooled, cover the machine with a suitable protective cover that does not retain
moisture. Do not use plastic as this material cannot breathe; it also allows condensation to form, which will cause your
machine to rust.
Prior to performing any maintenance, you must first shut off the Engine; wait five (5) minutes to allow parts to cool and
disconnect the Spark Plug wire, keeping it away from the Spark Plug.
