manual abstract
The debris shield can also help the operator determine the reach of the cutting line during operation as well as provide a limited barrier between the operator’s feet and the cutting attachment. DEBRIS SHIELD FOR CURVED SHAFT UNITS CUT-OFF KNIFE ON RIGHT SIDE If your unit has a curved shaft, line head rotation is clockwise. The knife will be on the right side of the debris shield. DEBRIS NOTE There are two columns of pictures for each column of procedures in this part of the manual. One column shows curved- shaft units, the other column is for straight-shaft units. Disregard the column which does not apply to your unit. Study the pictures which apply to your unit. WARNING DANGER Some units have a plastic debris shield. The plastic shield has a razor-sharp knife which trims the line whenever it becomes too long. If your unit has a debris shield with a cut-off knife, do not cut yourself when handling the line head and shield. Do not operate if the cut-off knife is missing. CUT ON THIS SIDE CLOCKWISE ROTATION STRAIGHT SHAFT UNITS CUT-OFF KNIFE ON LEFT SIDE If your unit has a straight shaft, line head rotation is counterclockwise. The knife will be on the left side of the debris shield. DEBRIS CUT ON THIS SIDE COUNTERCLOCKWISE ROTATION The proper debris shield must be in place on the unit when nylon cutting line is used. a) Units with EchomaticTM semi-automatic line head must have a debris shield with cut-off knife. b) Units with manual feed line head or blade head require a debris shield. Consult your operator’s manual for the proper debris shield. WARNING DANGER The cutting line can flap around if too much line is exposed. Always reinstall the plastic debris shield and cut-off knife when converting the unit for use with a semi-automatic feed type line head. A metal shield does not trim line. For nearly all cutting, it is good to tilt the line head so that contact is made on the part of the line circle where the line is moving away from you and the debris shield. (See appropriate picture.) This results in the debris being thrown away from you. Tilting the head to the wrong side will shoot the debris toward you. If the line head is held flat to the ground so that cutting occurs on the whole line circle, debris will be thrown at you, drag will slow the engine, and you will use up a lot of line. WARNING DANGER Use only ECHO quality nylon monofilament line of the diameter given in your operator’s manual. Never use wire or wire-reinforced line in place of nylon trimmer line. Load your nylon line cutting head only with nylon trimmer line of the proper diameter. WARNING DANGER Use extreme caution when operating over bare spots and gravel, because the line can throw small rock particles at high speeds. Debris shields on the unit cannot stop objects which bounce or ricochet off hard surfaces. The basic cutting actions pictured are: Trimming, scything, scalping and lawn edging. These actions are as follows The basic cutting actions pictured are: Trimming, scything, scalping and lawn edging. These actions are as follows Trimming can be done to cut through weed stems one at a time. Place the trimmer line head near the bottom of the weed—never high up, which could cause the weed to chatter and catch the line. Rather than cut the weed right through, just use the very end of the line to wear through the stem slowly. SCYTHING: This is the cutting or mowing of large grassy areas by sweeping or swinging the trimmer in a level arc. Use a smooth, easy motion. Do not try to hack or chop down the grass. The unit can be hand-held for scything. Scything is also very comfortable to do with the unit on a shoulder harness. Tilt the line head to direct the debris away from you on the scything stroke. Then return without cutting grass for another stroke. If you are well protected and do not care whether some debris is thrown in your direction, you may scythe in both directions. SCALPING and EDGING:Both of these are done with the line head tilted at a steep angle. Scalping is removing top growth, leaving the earth bare. Edging is trimming the grass back where it has spread over a sidewalk or driveway. During both edging and scalping, hold the unit at a steep angle and in a position where the debris, and any dislodged dirt and stone, will not come back towards you even if it ricochets off the hard surface. Although the pictures show how to edge and scalp, every operator must find for himself the angles which suit his body size and cutting situation. WARNING DANGER Do not use a blade for edging or scalping.
