Remove loose packing material. REMOVING UNIT FROM CARTON 1.
ASSEMBLY 4. F lip upper handlebar up to the operating position. Loosen both adjustment knobs (see Figure 3) and align the upper handlebar both sides to a comfortable operating position. Tighten the adjustment knobs securely. It is important to find a handlebar height that allows the cutting head to hover just above the ground and remain balanced so you do not have to push down or pull up on the handlebar.
ASSEMBLY INSTALLING THE CUTTING LINE There are two installation points on the line plate. Each point is 180 degrees apart. Always install two lines, one opposite the other of the same length and weight (diameter). 1. Insert the end of the cord into the side openings in the line plate (see Figure 4). 2. Push the cord through until the end comes out the center hole in the line plate. Adjust the cord ends so the tips are of equal length. 3.
OPERATION FILLING WITH OIL AND GASOLINE ! WARNING OIL FILL FUEL FILL ADD OIL BEFORE STARTING THE ENGINE The string trimmer is shipped without fluids installed. Keep the caps on the fuel and oil fills until you are ready to pour either gasoline or oil into the correct fill. Requires approximately 15 - 22 ounces of SAE 30 engine oil. Please refer to your Engine Owner’s Manual for detailed information on oil quantity and cold temperature oil specifications. 1.
OPERATION ! CAUTION CHECK THE ENGINE OIL LEVEL Check fuel level. Remove any debris from around the underside of the string trimmer. Manual Starting 1. Push the throttle control lever on the right side of the handlebar (see Figure 8) all the way forward (choke position). 2. Grasp the recoil starter and slowly pull until you feel resistance. Let the cord retract a little bit and then pull the cord rapidly to start the engine. One or two pulls usually starts the string trimmer.
OPERATION SETTING THE CUTTING HEIGHT ! CAUTION 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. Setting the cutting height is easy. Cutting heights range in 10mm (0.4 in). ! WARNING 3.5” 3.1” 2.7” 2.3” 1.
OPERATION CUTTING CORD RECOMMENDATIONS Cutting cord is available in Blue (175 mil) and Green (155 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: • If the cutting cord is purchased in rolls, cut to 25” lengths. • Cord life depends on trimming conditions. Replace cords when they become broken or frayed.
OPERATION CUTTING HEAD Allow the front end of the string trimmer to rest lightly on the cutting head as you are trimming. The cutting head should glide on the ground as you maneuver the string trimmer. To achieve the best and smoothest cut, do not lift up on the handlebar while operating your string trimmer. Lifting the handlebar will force weight down on the cutting head. This uses more energy, slows the cutting, and produces an unsatisfactory cut.
OPERATION CUTTING HEAD COMPONENTS ! CAUTION BEARING COVER Improper installation can cause damage to the cutting head bearings. Follow directions carefully to protect the string trimmer from damage. Assemble components in the order shown (see figure 13.) 1. Place the spacer and bearing cover (with the lip facing up) onto the shaft (Figure 13). 2. Align the flats at the center of the plates with the flat on the shaft and slide the line plate onto the shaft. Ensure they are facing top side up as shown. 3.
OPERATION OPERATING ENVIRONMENT ! WARNING The cutting head can easily throw debris at great velocity, which could cause personal injury or property damage. Do not run the string trimmer over loose gravel or mulch with the cutting head spinning. • The string trimmer discharges cut material to the right. • Always try to cut and trim with the uncut tall grass or weeds on the left. • Always check your work area before trimming and remove any debris that might tangle or damage the string trimmer.
OPERATION OPERATING ENVIRONMENT Wet Environments You can use the string trimmer in damp and wet conditions, after a rain, or in the early morning dew without clogging or stalling. You can mow wet areas such as ditches and around ponds. Note: NEVER mow in the rain. Water on the spark plug may cause the engine to stall. Dry Environments When trimming and mowing in very dry conditions, be extra cautious of cut grass, chaff, weeds, seeds, etc.
MAINTENANCE ! WARNING BEFORE PERFORMING ANY MAINTENANCE PROCEDURE STOP THE ENGINE, WAIT FIVE (5) MINUTES TO ALLOW ALL PARTS TO COOL. Disconnect the spark plug wire, keeping it away from the spark plug. Regular maintenance is the way to ensure the best performance and long life of your string trimmer. Please refer to this manual and the engine manufacturer’s owner’s manual for maintenance procedures.
MAINTENANCE CHANGING THE ENGINE OIL Tools and Supplies needed: • SAE 30 HD Oil (refer to your Engine Owner’s Manual for quantity required) • Suitable container for used oil • Cleaning Rags • Wooden pallet or workbench OIL CAP DIPSTICK NOTE: Drain the oil when the engine is warm. Warm oil drains quickly and completely. 1. For convenience, place the string trimmer up on a wooden pallet or workbench. 2.
