Protecting Yourself and Those Around You
This is a high-powered machine, with moving parts operating with high energy at high speeds. You must operate the machine
safely. Unsafe operation can create a number of hazards for you, as well as anyone else in the nearby area. Always take the
following precautions when using this machine:
Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and
themselves.
Always wear protective goggles or safety glasses with side shields while mowing to protect your eyes from possible thrown
debris.
Avoid wearing loose clothing or jewelry, which can catch on the mower’s moving parts.
We recommend wearing gloves while mowing. Be sure your gloves fit properly and do not have loose cuffs or drawstrings.
Wear shoes with non-slip treads when using your DR TRIMMER/MOWER. If you have safety shoes, we recommend wearing
them. Do not use the machine while barefoot or wearing sandals with exposed toes or heels.
Wear long pants while operating the DR TRIMMER/MOWER.
Use ear protectors or ear plugs rated for at least 20 dba to protect your hearing.
Keep bystanders at least 50 feet away from your work area at all times. The tips of the cutting cords on the DR
TRIMMER/MOWER can throw sticks, small stones, gravel, and bits of debris over long distances at great velocity. Do not
travel over loose materials such as gravel or mulch with the trimmer head spinning. Doing so could cause personal injury or
property damage from thrown objects. Release the bail bar to stop the spinning cords and shut off the engine when another
person or pet approaches.

Operating the Mower Safely
This is a high-powered machine, with moving parts operating with high energy at high speeds. You must operate the machine
safely. Unsafe operation can create a number of hazards for you, as well as anyone else in the nearby area. Always take the
following precautions when using this machine:
Never allow people who are unfamiliar with these instructions to use the DR TRIMMER/MOWER. Allow only responsible
individuals who are familiar with these rules of safe operation to use your machine.
Never place your hands, feet, or any part of your body on or under the mower deck in the path of the spinning cords, belt,
pulleys, or near the discharge opening while the engine is running. Keep area of discharge clear of people, animals, buildings,
glass, or anything else that will obstruct clear discharge, cause injury, or damage.
Your DR Trimmer/Mower is a powerful tool, not a plaything. Exercise extreme caution at all times. The design of your
machine is for trimming and mowing grass, weeds, and other growth as specified in this manual. Do not use it for any other
purpose.
Whenever you leave the operating position to make adjustments, change cords or if you have to remove grass or debris from
the underside of the deck, always shut off the engine and wait five (5) minutes to allow parts to cool. Remove the key, if so
equipped, and disconnect the spark plug wire and keep the wire away from the spark plug to prevent accidental starting.
When operating over uneven terrain and slopes, use extreme caution to ensure solid and firm footing. Keep a firm hold on
the handlebar and walk, never run.
Stop the cutting cords when crossing gravel drives, walks, or roads.
Never operate your unit on a slippery, wet, or muddy surface. Exercise caution to avoid slipping or falling.
Always operate the mower from behind the handlebar. Never pass or stand on the discharge side of the machine when the
engine is running or cutting cords are spinning.
Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the DR TRIMMER/MOWER.
This includes all shields and guards. Modifications to your machine could cause personal injuries and property damage and
will void your warranty.
If the cutting cords strike a foreign object or if your machine should start making an unusual noise or vibration, stop the
engine and wait five (5) minutes for all moving parts to come to a complete stop and cool. Vibration is generally a warning of
trouble. Disconnect the spark plug wire and inspect for damage. Clean and repair and/or replace damaged parts.
While using the DR TRIMMER/MOWER, do not hurry or take things for granted. When in doubt about the equipment or your
surroundings, stop the machine and take the time to look things over. Make sure that you have 100% control of the mower at
all times.
Watch for traffic when mowing near roadways.
Use the machine only in daylight.
Be cautious when using your DR TRIMMER/MOWER around fencing, wires, ropes, and hoses. It is possible that these and
other debris can become wound around the line plates of the machine, potentially damaging the bearings or injuring you.
Do not operate the DR TRIMMER/MOWER on slopes greater than 20 degrees.
Keep all nuts and bolts tight and keep the equipment in good operating condition.
Safety for Children and Pets
Tragic accidents can occur if the operator is not alert to the presence of children and pets. Children are often attracted to the
machine and the mowing activity.
precautions:
Keep children and pets out of the working area and under the watchful care of a responsible adult.
Be alert and turn the machine off if children or pets enter the work area.
Never allow children to operate the DR TRIMMER/MOWER.
Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

Safety with Gasoline - Powered Machines
Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or
explosion. Never overlook the hazards of gasoline. Always follow these precautions:
Never run the engine in an enclosed area or without proper ventilation as the exhaust from the engine contains carbon
monoxide, which 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 and open
flame, and out of the reach of children.
Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.
Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely. Don't handle gasoline if you or
anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Reinstall the fuel tank Cap and
fuel container cap 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 engine to cool completely before storing in any enclosure. Never store a machine that has gas in the tank, or a fuel
container, near an open flame or spark such as a water heater, space heater, clothes dryer or furnace.
Never make adjustments or repairs with the engine running. Shut down the engine, wait 5 minutes, disconnect the spark plug
wire, keeping it away from the spark plug to prevent accidental starting before making adjustments or repairs.
Never tamper with the engine’s governor setting. The governor controls the maximum safe operation speed and protects the
engine. Over-speeding the engine is dangerous and will cause damage to the engine and to the other moving parts of the
machine. If required, see your authorized dealer for engine governor adjustments.
Keep combustible substances away from the engine when it is hot.
Never cover the machine while the muffler is still hot.
Do not operate the engine with the air cleaner 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 the air filter.
The muffler and engine become very hot with use and can cause a severe burn; do not touch. Allow the engine to cool before
refueling, doing maintenance, or making adjustments.
Do not mow in the rain. Water on the spark plug may cause the engine to stall.
Keep combustible substances away from the engine when it is hot.
Never cover the machine while the muffler is still hot.

Tool needed:
1/2" Wrench
Check the tightness of the four Bolts that secure the Lower Handlebar to the
Frame using a 1/2" Wrench (Figure 3).
The Handlebar folds down for easy storage and the DR Trimmer/Mower is
shipped to you with them folded.
Note: Ensure that the teeth of the Handlebar Adjusters mesh correctly as you tighten
the Knobs in the following step.
1. Loosen both the Adjustment Knobs and move the Handlebar up or down
until the Notches on the Adjusters are aligned on both sides and tighten the
Knobs (Figure 4). This puts the Handlebar at a comfortable operating
position for many people.
It is important to find a Handlebar height that allows the Mow-Ball
comfortably hover just above the ground. When in use, proper adjustment is
critical to best performance. You may find you like different Handlebar heights
for different mowing conditions.
2. For other Handlebar height settings, loosen the Knobs, move the Handlebar
up or down until you are comfortable, and then tighten the Adjustment
Knobs securely. Take note of how many teeth you have moved away from the
aligned notches to align both sides.

Installing the Cutting Cords
s
There are two installation points on each Line Plate. Each point is 180 degrees
apart. Always install two Cords, one opposite the other at the same height.
Note: Soaking the Cutting Cords and trimming the ends at an angle will make
installation easier.
Side
Openings
1. Insert the ends of the Cords into the side openings in the Line Plate
(Figure 5).
2. Push the Cord through until the ends come out the center hole in the Line
Plate. Adjust the Cords so the tips are even.
3. Pull the Cords under the loop and push the loop up into the Line Plate
groove above them (Figure 6) and then pull the Cords tight.
If the tips of the cords are not even, it can cause unbalance of the trimmer
and will result in increased vibration.
Figure 7 illustrates the Cords installation on the Line Plates. It shows the Line
Plate from a top view. It may look complicated, but once you have done it a
couple of times, it’s easy. There are two installation points on each Line Plate.
Each point is 180 degrees apart. Always install two Cords, one opposite the
other.
Extending Cutting Cord Life
STORE YOUR CORD OUT OF THE SUN. UV can damage your cord causing
premature wear.
KEEP YOUR CORD HYDRATED. Soak your cord in water for at least 3 days
before using.

Adding Oil and Gasoline
Note: Refer to the Engine Manufacturers Manual for more detailed Engine information.
Tip: To avoid confusion, we recommend leaving the caps ON the Fuel and Oil Fills until you are ready to pour either gasoline or
oil into the correct Fill.
Note: You will need approximately 15 to 22 ounces of SAE 30 high detergent oil depending on Engine type. Use only SAE 30 high
detergent oil classified “For Service SF, SG, SH, SJ” or higher. Do not use special additives. Other types of oil could cause
problems with the operation of your machine. Please refer to your Engine Owner’s Manual for detailed information on oil
quantity and cold temperature oil specifications.
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
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 to ensure an accurate oil level reading.
you must add oil before starting the engine. Fill the reservoir slowly, checking the level frequently to
