Do not use this machine around underground pipes and wiring.

Prior to removing material from the Tines by hand, stop the Engine and remove the Spark Plug wire.

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 ROTO-HOG Mini Tiller 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 ROTO-HOG Mini Tiller 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

ROTO-HOG Mini Tiller 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.

Chapter 3: Operating Your DR ROTO-HOG Mini Tiller

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 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 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.

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.

Adjusting Wheels and Drag Stake

TO ADJUST WHEELS UP OR DOWN:

The wheels on the Tiller 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 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.

Transporting Your Tiller

Daily Checklist for the DR ROTO-HOG Mini Tiller

To help maintain your DR ROTO-HOG Mini Tiller for optimum performance, we recommend you follow this checklist each time you use your machine.

Before performing any maintenance procedure or inspection, flip the ON/OFF switch to the OFF position to stop the engine, wait five minutes to allow all parts to cool. Disconnect the spark plug wire, keeping it away from the spark plug.

[ ] 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

Before performing any maintenance procedure or inspection, flip the ON/OFF switch to the OFF position to stop the engine, wait five minutes to allow all parts to cool. Disconnect the spark plug wire, keeping it away from the spark plug.

If your DR ROTO-HOG Mini Tiller 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 ROTO-HOG Mini Tiller inside, but not near an open flame or spark such as found in a water heater.

After the DR ROTO-HOG Mini Tiller 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 engine in a vertical position.
