OPERATION SRM-2620T Operation With Blades Metal blades are very sharp and can cause severe injuries, even if engine is off and blades are not moving. Avoid contact with blades. Wear gloves to protect hands. Blade use demands specific brush cutter configuration. Operation without specified shield, barrier bar or U-handle, and harness can result in serious personal injury. Follow installation instructions.
SRM-2620T OPERATION Note: The barrier bar is used to restrict rearward movement of the unit. The barrier bar is not a handle and should not be gripped when using or carrying the unit. Blade Selection The type of blade used MUST be matched to the type and size of material cut. An improper or dull blade can cause serious personal injury. Blades MUST be sharp. Dull blades increase the chance of kick-out and injury to yourself and bystanders.
OPERATION SRM-2620T A trimmer-brushcutter with a metal blade can cause serious injuries if handled improperly. Always use extreme care when carrying or handling the equipment to avoid contact with the cutting edges of the blade. Use the optional blade cover when unit is not in use. Keep blades in protective packaging until ready to install. Store blades safely after removal to prevent injury from accidental contact. Use blade protectors to protect blade teeth during unit transportation.

SRM-2620T OPERATION Applications Nylon line heads may be used for trimming, scything, edging, and scalping of grass and light weeds. Trimming Feed the spinning line into the material to be cut. Tilt the line head to one side to direct cutting debris away from you: • Model SRM/PAS/SB/TX/C (Straight shaft, counter-clockwise line head rotation) - Tilt the cutting head down on the right side (muffler side) while cutting to direct cutting debris away from operator.
OPERATION SRM-2620T Push and Pull Forces Push and pull forces are reactive forces that push the equipment directly toward the operator, or that pull the equipment directly away from the operator. These forces are the result of cutting on the sides of the blade. The direction of the force depends on the side of the blade being used, and the direction of blade rotation at the point of contact.
SRM-2620T OPERATION Blade Cutting Problems Binding - Blades may bind in the cut if dull or forced. Binding can damage blade, and result in blade breakage or injury from fragments and flying debris. If a blade binds in a cut, don’t try to get it out by applying “up and down” force to pry the cut open. Applying prying force to the blade can bend the blade, and result in blade failure and injury.
MAINTENANCE SRM-2620T MAINTENANCE Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects away from all openings. Always stop engine, disconnect spark plug, and make sure all moving parts have come to a complete stop before removing obstructions, clearing debris, or servicing unit. Allow unit to cool before performing service. Wear gloves to protect hands from sharp edges and hot surfaces.
