DR TRIMMER/MOWER Controls and Features NOTE: The models shown in Figure 1 may look slightly different from your machine.
Unpacking the DR TRIMMER/MOWER Country Home Products ships the following items with your new machine. Please check to make sure you have everything listed below: Parts Supplied: • (2) Key (for Electric Start models only) NOTE: The Keys are attached to the Trimmer just below the bail bar spring (Figure 1 on page 10). • (1) Goggles for eye protection • (1) Metal Head Locking Tool • (1) Sample Pack of Trimmer Cord: - Small (Orange, .130") - Medium (Green, .155") - Large (Blue, .175") 1.
Adding the Engine Oil and Gasoline • • YOU MUST ADD OIL BEFORE STARTING THE ENGINE. THIS MACHINE 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 DIPSTICK 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.
Oil Fill Gas Fill Figure 2 Connecting the Battery Wire (Electric-Starting Models Only) We ship all Electric-Starting Trimmers with the negative Battery wire disconnected. This prevents the Battery from discharging during shipment. Before using your Trimmer, you must connect the Battery wire. 1. Connect the black wire by pushing the plastic connector onto the negative (–) Battery terminal as shown in Figure 3. NOTE: The red wire should already be attached to the positive terminal.
Adjusting the Handlebar It is important to find a Handlebar height that allows the Mow-Ball™ Support to glide along the ground and remain balanced so you do not have to push down or pull up on the Handlebar. At the proper height, your hands should rest at a comfortable level and the front end of the Trimmer should roll easily on the Mow-Ball™ Support as shown in Figure 15 on page 25. You may find you like different Handlebar heights for different mowing conditions.
Adjusting the PTA™ (Parallel Trimming Action) Lever - SPRINT®, PRO and COMMERCIAL BEFORE PERFORMING ANY ADJUSTMENT, MAINTENANCE PROCEDURE OR INSPECTION, STOP THE ENGINE, WAIT FIVE (5) MINUTES TO ALLOW PARTS TO COOL AND DISCONNECT THE SPARK PLUG WIRE, KEEPING IT AWAY FROM THE SPARK PLUG. NOTE: This adjustment is not applicable to the SELF-PROPELLED model. It is easy to adjust the PTA™ feature. If you have moved the Handlebar up or down, the PTA™ (Parallel Trimming Action) Lever may need adjustment.

CHAPTER 4 OPERATING YOUR DR TRIMMER/MOWER This chapter covers the procedures for starting and stopping your new DR TRIMMER/ MOWER and discusses basic operation features. You may find it helpful to review the DR TRIMMER/MOWER Controls and Features picture (Figure 1 on page 10) before reading this chapter. • • • 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 AS IT COULD CAUSE SERIOUS INJURY.
Electric-Starting NOTE: Use the following steps with electric-starting models only. 1. Push the Throttle Control Lever on the right side of the Handlebar (Figure 1 on page 10) all the way forward to the RABBIT (Fast) position. 2. If your model has an Engine Primer, push the Primer Bulb IN (Figure 1 on page 10) and completely release it, lifting your finger and letting it pop back to its original position. Repeat three to four times. NOTE: Priming is usually not necessary when restarting a warm engine.
Engaging the Trimmer Head Bring the Bail Bar toward you and grip it together with the Handlebar (Figure 1 on page10). Keep holding the Bail Bar to the Handlebar. The Cutting Cords will rotate and will continue to rotate until you release the Bail Bar. Stopping the Cords from Spinning Release the Bail Bar from the Handlebar. The Trimmer Head will stop spinning while the engine continues to run.
Using the PTA™ (Parallel Trimming Action) - SPRINT®, PRO and COMMERCIAL models only Your DR TRIMMER/MOWER’S PTA™ feature allows you to move the machine in a straight line while the Trimmer Head is both pivoted and tilted to the left for better access to fence lines and other obstacles. PTA™ allows you to trim in difficult areas without having to pull the machine back and forth. The following two sections explain how to use the PTA™ and how to return your Trimmer to Normal operation after using PTA™.
Engaging the PTA™ 1. Stand in the operator’s position. 2. Pull the PTA™ Lever (Figure 7) against the Handlebar and hold it there. This unlocks the Axle (Figure 8). NOTE: Figure 8 shows the Axle with the wheel removed for clarity. 3. Push down on the Handlebar to tip the nose of the machine a few inches off the ground. Balancing the weight of the machine on the wheels makes it easier to pivot the front of the Trimmer to the left. Figure 7 4.
The DR TRIMMER/MOWER Cutting Cords BEFORE PERFORMING ANY ADJUSTMENT, MAINTENANCE PROCEDURE OR INSPECTION, STOP THE ENGINE, WAIT FIVE (5) MINUTES TO ALLOW PARTS TO COOL AND DISCONNECT THE SPARK PLUG WIRE, KEEPING IT AWAY FROM THE SPARK PLUG. RUNNING THE TRIMMER WITH ONLY ONE CORD INSTALLED, OR CORDS INSTALLED AT OTHER THAN 180 DEGREES APART CAN CAUSE EXCESSIVE VIBRATION AND MAY DAMAGE THE MACHINE. The following figures (Figures 9 and 10) illustrate the Cords installation on the line plates.
Installing Cords The Cord installation method is shown in Figures 11–13. Your DR TRIMMER/MOWER shipped from the factory with the Cords installed in this manner. WHEN USING PTA™, INSTALL THE CUTTING CORDS IN ONE OF THE BOTTOM FOUR LINE PLATES. INSTALLING THE CUTTING CORDS ON THE UPPER LINE PLATES CAN CAUSE THE CORD TO HIT THE WHEEL. FOR MORE INFORMATION ON USING PTA™, SEE USING PTA™ ON PAGE 20.
Cord Tips We ship three (3) thicknesses of Cutting Cord with your DR TRIMMER/MOWER. The Cords are Blue (175-mil), Green (155-mil) and Orange (130-mil). Because conditions and vegetation vary so much, you should experiment with Cord weights (diameters) to discover what works best for your particular mowing and trimming situations. Here are a few things to keep in mind: 24 • If you buy Cutting Cord in rolls, cut it in 23" lengths. • Cord life depends on trimming conditions.
Adjusting the Cutting Height WHEN USING THE PTA™ FEATURE, INSTALL THE CUTTING CORDS IN ONE OF THE FOUR BOTTOM LINE PLATES ONLY. Adjusting the cutting height is easy. Cutting heights range in 1/2-inch increments from 1-1/2 inches when using the bottom Line Plate, to approximately 4 inches when using the top Line Plate (Figure 14). Install the Cutting Cords in the Line Plate that gives you the desired cutting height.
Obstacle Tips Dealing with obstacles in the terrain is easy with your new DR TRIMMER/MOWER. The following section explains how to approach most common obstacles. THE TRIMMER ENGINE'S POWER CAN EASILY THROW STONES, STICKS, AND OTHER DEBRIS AT GREAT VELOCITY, WHICH COULD CAUSE PERSONAL INJURY OR PROPERTY DAMAGE. DO NOT RUN THE MACHINE OVER GRAVEL DRIVEWAYS OR OVER LOOSE STONES OR MULCH WITH THE TRIMMER HEAD SPINNING. Tip: The DR TRIMMER/MOWER discharges cut material to the right.
Heavy Growth • Take your time in heavy growth. • Be sure to keep uncut material to your left, maintaining a clear discharge area to your right (Figure 17). • If the machine cannot do it all in one pass, overlap half of the cutting swath. • If the grass is very thick and heavy, try raising the Trimmer Head off the ground a few inches by pushing down on the Handlebar. Cut the material at this height, and then make a second pass with the Mow-Ball™ Support close to the ground.
MAKE SURE OF YOUR FOOTING WHEN OPERATING IN WET CONDITIONS. Wet Conditions Because there is no housing to restrict the flow of cut material, you can also use your DR TRIMMER/MOWER to mow wet or heavy growth. You can use the DR in damp conditions, after a rain, or in the early morning dew without clogging or stalling. You can also mow wet areas such as ditches and around ponds (Figure 18). NOTE: NEVER mow in the rain. Water on the spark plug may cause the engine to stall.
CHAPTER 5 MAINTAINING THE DR TRIMMER/MOWER This chapter covers regular maintenance procedures that will ensure the best performance and long life of your DR TRIMMER/MOWER. For Engine maintenance, please refer to the Engine Owner’s Manual that came with your Trimmer. Service intervals listed in the checklist below supercede those listed in the Engine Owner’s Manual.
