RULES FOR SAFE OPERATION

WARNING DANGER
All models trimmers and brush cutters can throw small stone , metal or small objects as well as the material being cut. Read these Rules for Safe Operation with care.
Follow the instructions in your operator’s manual.
Read the operator’s manual carefully. Be thoroughly familiar with the controls and proper use of the unit. Know how to stop the unit and shut off the engine. Know how to unhook a harnessed unit quickly. Never allow anyone to use the unit without proper instruction. Be sure the operator wears the foot, leg, eye, face and hearing protection.
Do not rely on the debris shield on the unit to protect your eyes from ricocheting or thrown objects. Keep the area clear of bystanders, children and pets. Never allow children to  perate or play with the unit. Do not allow anyone to enter the operating DANGER ZONE with you. The danger zone is an area 15 meters in radius (about 16 paces) or 50 feet.
Insist that persons in the RISK ZONE beyond the danger zone wear eye protection from thrown objects. If the unit must be used where there are unprotected people, operate at a low throttle speed to reduce the risk of thrown objects.
Hold the grass trimmer with the right hand on the trigger handle and the left hand on the front handle.
Keep a firm grip with both hands while in operation. Grass trimmer should be held at a comfortable position with the trigger handle about hip height. Maintain your grip and balance on both feet. Position yourself so that you will not be drawn off balance by the kick-back reaction of the nylon head.
Move the stop switch to “stop” position when the engine idles, insure it reliable before cutting. Only may continue to operate the unit when stop switch is in good condition.
Routines for checking that the cutting attachment stops turning when the engine idles.

WARNING DANGER
In addition to head, eye, face and ear protectors shoes to protect your feet improve your footing on slippery surfaces. Do not wear ties, jewelry, or loose, dangling clothing which could be caught in the unit.
Do not wear open-toed footwear, or go barefoot or bare legged. In certain situations you must wear total face and head protection.

NO PERSON EXCEPT OPERATOR ALLOWED 15 METERS RADIUS DANGER ZONE.EYE,EAR,FACE, FOOT,LEG AND BODY PROTECTION MUST BE WORN BY  OPERATOR.PERSONS IN ZONE OR RISK BEYOND DANGER ZONE SHOULD WEAR EYE PROTECTION AGAINST THROWN OBJECTS.RISK DIMINISHES WITH DISTANCE FROM DANGER ZONE.

CUTTING WITH A NYLON HEAD

Line head rotates in a CLOCKWISE direction. The CUT-OFF KNIFE will be on the right side of the debris shield.

WARNING DANGER
The proper debris shield must be in place on the unit when nylon cutting line is used. The cutting line can flap around if too much line is exposed. Always use the plastic debri shield with cut-off knife when using nylon cutting heads.
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 appropraite picture) This results in the debris being thrown AWAY from you.

WARNING DANGER
Tilting the head to the wrong side will shoot the debris TOWARDS 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 down, and you will use up a lot of line.

WARNING DANGER
Use only quality nylon monofilament line of the diameter 1.8mm. 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.

TRIMMING:
This is feeding the trimmer carefully into the material you wish to cut. Tilt the head slowly to direct debris away from you. If cutting up to a barrier such as fence, wallor tree, approach from an angle where anydebris ricocheting off the barrier will fly away from you. Move the line head slowly until the grass is cut right up the barrier, but do not jam(overfeed )the line into the barrier. If trimming up to a wire mesh or chain linked fence be careful to feed only up to wire. If you go to far the line will snap off around the wire. 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.

WARNING DANGER
Do not to use a steel blade for edging or scalping.

SCALPING AND ENGING:
Both of these are done with the line head tilted at a steep angle Scalping is removing top growth leaving the earth bear. Edging is trimming the grass back where it has spread over a sidewalk or drive way. During both edging and scalping, hold the unit a steep angle and in a position where the dibris, and any dislodging dirt and stones, will not come back towards you even if it ricochets off the hard surface. Although the picture shows how to edge and scalp every oprator must find for himself the angles which suits his body size and cutting situation.

WARNING DANGER
Do not trim in any area where there are strands of fencing wire. Wear protective safety protecting, Do not cut where you cannot see what the cutting device is cutting.
