B45045 Part number: 72451-17203 Figure 23 Cutting Grass—Units equipped with a trimmer head Your Shindaiwa unit may be equipped with one of several Shindaiwa trimmer head models, each with features for specific applications and/or operational requirements. NOTE: For proper operation, always refer to the instructions accompanying the trimmer head being used. Available trimmer head styles include: n Semi-automatic. Trimmer line is indexed when the operator taps the trimmer head on the ground during operation. n Manual. The operator indexes line manually with the grass trimmer stopped. n Fixed. The operator must stop the unit and add new lengths of trimmer line manually. n Flail. This device, designed for clearing weeds and light brush, features three nylon blades attached to the head by pivots. NOTE: Additional hardware may be required to mount the Fixed Line or the Flail type trimmer heads. CAUTION! Do not push the rotating line into trees, wire fences or any material that could tangle or break line ends. Engine Operating Speeds Operate the unit at full throttle while cutting grass. Trimming and Mowing Grass CUTTINGPATHRETURNPATH CAUTION! Operation of trimmer without a cutting attachment shield and using excessive line length can lead to premature clutch failure. Figure 24 CAUTION! Operation at low RPM can lead to premature clutch failure. Edging Tilt the handle about 100° to the left (from horizontal) and move forward, holding the trimmer vertically as shown in Figure 25. Hold the trimmer so the trimmer head is angled slightly into the area to be cut. To ensure maximum trimmer-line service life, cut only with the tip of the trimmer line. Cut grass by swinging the trimmer from left to right. Keep the trimmer head horizontal. See Figure 24. Figure 25 Using a Blade C2510 Blade Thrust ‘Blade thrust’ is a sudden sideways or backward motion of the brushcutter. Such motion may occur when the blade jams or catches on an object such as a sapling tree or tree stump. BE CONSTANTLY ALERT FOR BLADE THRUST AND GUARD AGAINST ITS EFFECTS! Brushcutter Handlebar A brushcutter handlebar or barrier bar helps prevent the operator from moving forward, or the unit moving rearward, thus preventing inadvertent bodily contact with the blade. ALWAYS KEEP THE HANDLEBAR OR BARRIER BAR SECURELY IN PLACE ON THE UNIT! Brushcutter Shoulder Strap A shoulder strap provides additional protection against blade thrust. In addition, a shoulder strap gives significant support and comfort to help ensure safe and efficient operation. When operating a C2510 with a blade, make sure both the handle and shoulder strap are adjusted to the size of the operator using the unit. Engine Operating Speeds Operate the unit at full throttle while cutting. Best fuel efficiency is obtained by releasing the throttle when swinging back after a cut. n To prevent possible engine damage, do not allow the brushcutter to run at high speeds without a load. n Avoid operating the engine at low speeds. Doing so can lead to rapid clutch wear. In addition, slow-speed operation tends to cause grass and debris to wrap around the cutting head. WARNING! n Before working with a blade- equipped unit, always inspect and clean the area of objects that could interfere with or damage the blade. n Never use a blade near sidewalks, fence posts, buildings or other objects that could cause injury or damage. n Never use a blade for purposes other than those for which it was designed. n Whenever you strike a hard object with a blade, always stop the brushcutter and carefully inspect the blade for damage. NEVER OPERATE THE BRUSHCUTTER WITH A DAMAGED BLADE! n A blade-equipped unit must be equipped with a bicycle-type handlebar or barrier bar as well as a harness or shoulder strap. n Always make sure the cutting attachment shield is properly installed before operating this unit. Operating Units with a Blade The blade rotates counter-clockwise. For best performance and to minimize being stuck by debris, move the blade from right to left while advancing on your work. Position the blade so cuts are made between the blade’s 8 o’clock and 10 o’clock positions (as viewed from above). DO NOT cut between the 10 o’clock and 5 o’clock positions. Cut on the left side of the blade. KEEP YOUR BODY OUTSIDE THE PATH OF BLADE ROTATION Ten O'clock DO NOT CUT Blade Rotation OK To Cut Eight O'clock WARNING! When cutting wood with a saw, feed the blade slowly—never strike or “slam” a spinning blade against the wood. Five O'clock Figure 26 Vertical Cuts Hold the brushcutter with the blade at a 90° angle to the ground so the blade’s bottom edge rotates toward the operator. Move the blade from top to bottom through the cut, and cut only with the bottom edge of the blade. WARNING! DO NOT use 2-tooth or non-Shindaiwa approved 4-tooth cutting blades with Shindaiwa trimmers and brushcutters. Figure 27 WARNING! When making vertical cuts, never allow the blade to exceed waist height. General Maintenance IMPORTANT! MAINTENANC...
