Safety with Gasoline-Powered Machines

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 PILOT 4 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.

 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 PILOT 4 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

PILOT 4 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.  Replace rubber Fuel Lines and Grommets when worn or damaged, but do not use over five (5) years.

Adding the Gasoline and Oil

Figure 3

Engine is shipped from factory without oil. You must add engine oil before starting engine. If engine is started without oil, engine may be damaged beyond repair and will not be covered by warranty.

Always fill the Fuel Tank outdoors or in a well-ventilated area, away from sparks, open flames, pilot lights, heat, and other ignition sources.

Filling the Fuel Tank

1. Shut-off engine and allow engine to completely cool before refilling the fuel tank.

2. Move to a well ventilated area, outdoors, away from flames and sparks.

3. Clean debris from area around the fuel cap.

4. Loosen fuel cap slowly. Prevent the cap from coming in contact with dirt or debris.

5. Carefully add fuel without spilling.

6. Do not fill gas tank completely full, allow space for fuel to expand.

7. Immediately replace fuel cap and tighten. Wipe off spilled fuel and allow to dry before starting engine.

Note: To refill the Fuel Tank, turn the Engine OFF, and let the Engine cool at least five minutes before removing the Fuel Tank Cap.

 Never store engine with fuel in the tank indoors. Fuel and fuel vapors are highly flammable.  An adult only must always handle and fill the engine with fuel.  Always handle gas in a well ventilated area, outdoors, away from flames or sparks.  Do not start engine if fuel is spilled. Wipe off excess fuel and allow to dry. Remove engine from area to avoid

sparks.

Checking and Adding Oil

To operate the engine, we recommend using 4-cycle oil (194211), or an equivalent 10W-30 engine oil to ensure that the engine operates correctly throughout the life of the engine. Use straight unleaded premium gasoline, low/no ethanol blends recommended.

 Engine is shipped from factory without oil. You must add engine oil before starting engine. If engine is started

without oil, engine may be damaged beyond repair and will not be covered by warranty.

 Engine must be tipped forward with gas tank down when checking oil level or filling with oil (Figure 4). Failure to do

so can result in overfilling the engine with oil which will impair the engine’s performance.

1. Be sure the engine is located on a level surface before

checking or refilling oil. Proper position for checking oil level or refilling oil is face down, with the gas tank of the Tiller/Cultivator down on a horizontal surface (Figure 4).

2. Clean around oil fill area.

3. Unscrew dipstick and wipe clean with cloth.

4. Reinsert dipstick (must be fully threaded for accurate

reading).

5. Unscrew and check dipstick. If no oil shows on the

Chapter 3: Operating Your DR PILOT 4 Cycle Tiller/Cultivator

Operation Tips

 The clutch will transfer maximum power after about two hours of normal operation. During this break-in period

clutch slippage may occur. The clutch should be kept free of oil and other moisture for efficient operation.

 Cultivate without placing excessive body weight on the unit. The Tiller/Cultivator operates most efficiently with the

weight of the unit itself.

 Never run engine indoors. Exhaust fumes are deadly.  Do not spray water on or near the electronics of the Tiller/Cultivator as this may result in damage to the electrical

components.

 For cold weather operation, store the unit in a cool environment. Transferring the unit from a cold to a warm place

can cause the build up of harmful condensation.

 Make sure the unit is in a stable position before pulling the starter handle.  When the unit starts to fire or run, return both hands to the handlebar position to maintain control and stability of

the unit.

 Starter rope can cause an unanticipated jerk towards engine. Please follow instructions to avoid injury.  Never leave engine running while unattended. Turn off after every use.  Never carry Tiller from one location to another while engine is running.  Always wear a protective hearing device.  Do not start engine if fuel is spilled. Wipe off excess fuel and allow to dry.

Starting and Stopping Engine

DO NOT attempt to start engine in the following ways:

 DO NOT use starting fluid.  DO NOT spray flammable liquids or vapors into air cleaner, carburetor or spark plug chamber.  DO NOT remove spark plug and attempt to start engine. Flammable fuel can spray out & ignite from a spark from

spark plug.

Note: If engine fails to start after following starting procedures, please contact us at www.DRpower.com or call 1-800-DROWNER (376-9637) for assistance.

 Move engine to a well ventilated area, outdoors, to prevent carbon monoxide poisoning.  Move to an area away from flames or sparks, to avoid ignition of vapors if present.  Remove all debris from air cleaner holes and gas cap

to ensure proper air flow.

 If it is the first time starting the Tiller/Cultivator,

make sure the 4-cycle oil has been poured into the oil fill area to the correct level.

COLD ENGINE START:

Starting engine for first time or after engine has cooled off or after running out of fuel.

Adjusting Wheels and Drag Stake

TO ADJUST WHEELS UP OR DOWN:

The wheels on the Tiller/Cultivator can be adjusted to one of three positions (Figure 7). The LOW wheel position is used for transporting the cultivator across a smooth level surface while the engine is not running. The HIGH and HIGHEST wheel positions are used when cultivating in soil and help stabilize the unit when cultivating at different depths.

1. Pull the locking metal sleeve against the spring, away

from the vertical guide until it releases from one of the three notched positions in the vertical guide (Figure 8).

2. Slide the wheel set up or down to the desired position,

and release the locking metal sleeve until it locks into desired notch in the vertical guide.

TO ADJUST THE DRAG STAKE:

The drag stake is used to help regulate cultivating depth and control the Tiller/Cultivator from leaping forward during operation. Resistance to forward motion is greatest when the drag stake is set in its lowest position allowing for deeper cultivation.

1. Pull the pin out of the drag stake mount hole (Figure 9).

2. Position the drag stake so the pointed tip is directed

downward.

3. Insert the pin into the hole that achieves desired depth.

Figure 7

Transporting Your Tiller/Cultivator

Never transport engine inside an enclosed space within a vehicle. Fuel or fuel vapors may ignite causing serious injury or death.

1. After using the tiller/Cultivator, and before transporting it

in a truck bed, check that the gas cap is screwed on (clockwise) tightly. The gas cap will not leak during transporting if gas cap is tight.

2. If fuel is present in the fuel tank, transport in an open

vehicle in an upright position.

3. If an enclosed vehicle must be used, remove gas into an

approved red fuel container. DO NOT siphon by mouth.

4. Wipe away any spilled fuel from engine and

tiller/Cultivator. Allow to dry.

5. Run engine to use up the fuel in the carburetor and fuel

tank. Always run engine in a well ventilated area.

Daily Checklist for the DR PILOT 4 Cycle Tiller/Cultivator

To help maintain your DR PILOT 4 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. See page 9. [ ] 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 Hood are free of accumulated debris.

End of Season and Storage

 If your DR PILOT 4 Cycle Tiller/Cultivator will be idle 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 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 seat the Valves to prevent moisture buildup.

 Clean or replace the Engine Air Filter Element. See page 15.  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 PILOT 4 Cycle Tiller/Cultivator inside, but not near an open flame or spark such as found

in a water heater.

 After the DR PILOT 4 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.

 Store 4-cycle Tiller/Cultivator engine in a vertical position.
