General Safety (Continued)
Protecting Yourself and Those around You
Slope Operation
Slopes are a major factor related to slip and fall accidents. All slopes require caution. If you feel uneasy on a slope, do not mow it.
Always take the following precautions when using this machine on slopes:
Always mow across the face of slopes. Exercise extreme caution when changing direction on slopes.
Never operate near drop-offs, ditches, or embankments, or on slopes greater than 20 degrees
Never operate on wet or slippery slopes.
This is a high-powered machine with moving parts operating at high speeds. Always take the following precautions when
operating this machine:
Always wear protective goggles or safety glasses with side shields.
Wear sturdy shoes with non-slip treads.
Wear long pants while operating the mower.
Avoid wearing loose clothing or jewelry which can catch on moving parts
Use ear protectors or ear plugs.
We recommend wearing gloves while mowing. Be sure your gloves fit properly and do not have loose cuffs or drawstrings.
Allow only responsible adults who are familiar with these safety rules and operating instructions to use your DR FIELD and
BRUSH MOWER.
Keep your hands and feet away from the blades, belt, pulley, and concealed areas while the engine is running.
Keep people and pets away from your machine and out of the work area at all times. Disengage the blade and stop the engine
if a person or pet is within 100 feet of the machine.
Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last
saw them.
Never allow people to ride on the mower.
Before mowing, clear the area of objects such as rocks, toys, wire, bones, sticks, etc.
Never remove or alter standard parts or add anything to the DR FIELD and BRUSH MOWER especially all shields and guards.
Before and while moving backwards, look behind, and down, for small children.
Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.
Use caution when mowing close to fences, buildings, and trees so as not to hit the handle bar. You could injure your hand or
lose control of the machine.
Use the DR FIELD and BRUSH MOWER only in daylight or very well lit work areas.
Be sure all blade and wheel controls are disengaged before attempting to start the engine. Engage and disengage the blade a
few times to get used to it before mowing.
Always give undivided attention to the machine and your surroundings. Watch for traffic when mowing near roadways.
Disengage the mower blades and exercise extreme caution when on or crossing drives, walks, or roads.
In an emergency, to quickly stop the cutting blade and shut off the engine, remove your hand from the operator presence
lever on the left handlebar.
Always shut off the engine whenever you leave the machine.
When operating over uneven and/or slippery terrain, use extreme caution to ensure solid and firm footing. Keep a firm hold
on the handlebars and walk, never run.
Do not operate the machine when under the influence of drugs, alcohol, or medication.

Safety with Gasoline - Powered Machines
A Note to All Users
Under California law, and the laws of some other states, you are not permitted to operate an internal combustion engine using
hydrocarbon fuels without an engine spark arrester. This also applies to operation on US Forest Lands. All DR®FIELD and
BRUSH MOWERS shipped to California, New Mexico and Washington State are provided with spark arresters. Failure of the
owner or operator to maintain this equipment in compliance with state regulations is a misdemeanor under California law and
may be in violation of other state and/or federal regulations. Contact your appropriate local or state organization for specific
information in your area.
No list of warnings and cautions can be all-inclusive. If situations occur that are not covered by this manual, the operator must
apply common sense and operate this DR FIELD and BRUSH MOWER in a safe manner. Contact us at www.DRpower.com or call
1-800-DR-OWNER (376-9637) for assistance.
Gasoline is a highly flammable liquid that gives off flammable vapor that can be ignited and cause a fire or explosion. Always
follow these precautions:
Never run the engine in an enclosed area or without proper ventilation as the exhaust contains carbon monoxide, an odorless,
tasteless, and poisonous gas.
Store all fuel and oil in containers specifically designed and approved for this purpose. Keep away from heat and open flame
and out of the reach of children.
Replace rubber fuel lines and grommets when worn or damaged or after 5 years of use, whichever comes first.
Fill the gasoline tank outdoors with the engine off and after the engine has cooled completely. Do not handle gasoline if you
or anyone nearby is smoking.
If you spill gasoline do not start the engine. Move the machine away from the area until the gas vapors have dissipated.
Before performing engine maintenance or repairs; shut down the engine, disconnect the spark plug wire(s), and wait 5
minutes for the engine to cool.
Never change the engine governor settings or modify the engine speed.
Never check for an ignition spark with the spark plug or spark plug wire(s) removed. Always use an approved spark tester.
Never tamper with safety devices. Regularly check their proper operation.
Allow the engine to cool completely before storing in any enclosed area.
Keep combustible substances away from the engine when it is hot. Never cover the machine while the muffler is still hot.
To reduce fire hazard, keep the engine and muffler free of debris build-up.
Do not operate the engine with the air cleaner or the carburetor air intake cover removed.
Do not use flammable solutions to clean the air filter.
Never operate the engine without the muffler and deflector, if so equipped. Inspect the muffler and deflector periodically and
replace if necessary.
The muffler and engine become very hot and can cause a severe burn. Do not touch.

Connecting the Battery Wire
We ship all Electric-Starting Mowers with the negative terminal Battery wire
disconnected. This prevents the Battery from discharging during shipment.
Before using your Mower, you must connect the Battery wire.
1. Connect the negative (black) wire to the negative terminal on the Battery by
sliding the Connector onto the Terminal (Figure 9).

Adding Oil and Gasoline
Note: Please refer to your Engine Owner’s Manual for detailed oil information
regarding Oil weight based on ambient temperature
1. Place the machine on a level surface and initially add 1/2 of oil
recommended by the Engine manufacturer into the Oil Fill (Figure 10,
Electric Start Machines) or (Figure 11, Manual Start Machines).
2. Wait one minute for the oil to settle and check the Dipstick. Continue
adding a few ounces of oil at a time, rechecking the Dipstick until the oil
reaches the full mark. Be careful not to overfill.
3. Fill the Fuel Tank to not more than 1/4" from the bottom of the Fill Neck
with fresh, unleaded gas. See your Engine Owner’s Manual for more
information.
Check the Tire Pressure
Tools Needed:
Tire Pressure Gauge
Air Compressor
1. Remove the Valve Stem Protective Cap (Figure 12) and check the tire
pressure with a Tire Pressure Gauge.
2. Compare the tire pressure reading from step 1 with the manufacturer's
recommended tire pressure stamped on the side of the tire.
3. If the pressure is too low, add air through the Valve Stem with an air hose.
4. Replace the Valve Stem Protective Cap when finished.

(except Premier)
You must add Oil before starting the engine. This machine is shipped
without oil. Traces of oil may be in the reservoir from factory testing, but
you must add oil before starting the engine. Fill the reservoir slowly,
checking the level frequently to avoid overfilling.
To get an accurate reading when checking the oil level:
- The machine should be on a level surface.
- The dipstick SHOULD be screwed down on Briggs & Stratton
Engines to ensure an accurate oil level reading.
Before filling the Fuel Tank; turn the Engine OFF, and let it cool at least five
minutes before removing the Gas Fill Cap
Do not over inflate the tires. Inflate to the manufacturers recommended
pressure found on the tires.
