Rules for safe operation with nylon line cutting head
Use correct cutting attachment
Operate the machine with its throttle trigger fully grasped for higher engine speed.
Do not give an excessive load to the spinning cutting head to stop.
In case of cutting the thick grass, cut the grass little by little so as to maintain engine speed.
When the rotation of the cutting head stops during operation, immediately release the
throttle trigger to lower the engine speed, pull the machine away from the grass, and fully
grasp the throttle trigger and rotate the cutting head to continue cutting.
Stop the engine immediately when grass or cord / string like object wound around the
cutting head, and take them off before starting the engine.
The basic cutting actions pictured are: Trimming, scything, scalping and lawn edging.
These actions are as follows:
Trimming
1. Angle to wall 2. Debris 3. Knife side raised 4. Angle to ground
This is feeding the trimmer carefully into the material you wish to cut.
Tilt the head slightly to direct the debris away from you.
If cutting up to a barrier such as a fence, wall or tree, approach from an angle where any debris
ricocheting off the barrier will fly away from you.
Move the line head slowly until the grass is cut right up to the barrier, but do not jam (overfeed)
the line into the barrier.
If trimming up to wire mesh or chain link fencing, be careful to feed only up to the wire.
If you go too far, the line will snap off around the wire.
Trimming can be done to cut through weed stems one at a time.
Place the nylon line cutter 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.
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.
DANGER
Always stop the engine when a cutting attachment jam occurs.
Do not attempt to remove an object causing a jam if the engine is running.
Injury can occur if a jam is removed and the cutting attachment suddenly starts.
WARNING
Serious injury may result from the improper use of cutting attachment.
Read and comply with all safety instructions listed in this Manual.
Use only flexible, non-metallic line recommended by ECHO.
Use only cutting attachments recommended by ECHO.
Excessive nylon line beyond cut off knife could fly off when the nylon line cutter
starts rotating after adjustment of nylon line length.
Use extreme caution when operating over bare spots and gravel, because the line
can throw small rock particles at high speeds.
The shield on the unit cannot stop objects which bounce or ricochet off hard
surfaces.
Do not trim in any area where there are broken strands of fencing wire.
Remove the broken pieces of wire, or give the area wide berth.
Wear proper safety protection.
Do not cut where you cannot see what the cutting device is cutting.
