5 IMPORTANT SAFETY INSTRUCTIONS
WARNING
■ To reduce the risk of serious injury:
– Never use wire or metal-reinforced line or other 
material in place of the recommended nylon cutting 
line. Pieces of wire could break off and be thrown at 
high speed toward the operator or bystanders.
■ A cracked, damaged or worn out mowing head may 
shatter at high speeds and cause serious or fatal injury.
– Have a cracked, damaged or worn out mowing head 
replaced immediately, even if damage appears to be 
limited to superficial cracks.
■ When working close to fences, sides of buildings, tree 
trunks of other such objects, be alert to an increased 
possibility of ricochets.
5.8.3 Using a Grass Cutting Blade
► When working with a grass cutting blade, sweep the 
trimmer in a controlled manner, parallel to the ground in 
front of you. To reduce the risk of kickout, use the left side 
of the cutting blade.
All kinds of grass and weeds can be cut with a grass cutting 
blade.
– The 4-tooth grass cutting blade is intended to cut grass 
and weeds. It has 4 cutting knives with cutting edges on 
both sides, i.e., front and rear. When the cutting edges on 
one side become dull, the blade can be turned over to 
utilize the cutting edges on the other side before it is 
resharpened.
– The 8-tooth grass cutting blade is recommended for 
cutting fern or similar fleshy vegetation. When the cutting 
edges on one side become dull, the cutting edges have to 
be resharpened. The blade cannot be turned over to 
utilize the cutting edges on the other side.
WARNING
■ Improper use of a grass cutting blade may cause it to 
crack, chip or shatter. Thrown blade fragments may 
seriously or fatally injure the operator or bystanders. To 
reduce the risk of injury:
– Avoid contact with hard or solid foreign objects such 
as stones, glass, rocks or pieces of metal.
– Inspect the grass cutting blade at regular, short 
intervals for signs of damage. Do not continue 
working with a damaged grass cutting blade.
– Resharpen the grass cutting blade regularly as 
described on its packaging or instruction leaflet.
– Never attempt to cut woody material with the grass 
cutting blade.
5.8.4 Using a Brush Knife
A brush knife is suitable for applications ranging from cutting 
matted grass to clearing weeds, wild growth and scrub 
brush.
– Take care to clear area of all objects and 
debris before trimming along fences or 
walls, near tree trunks or other objects 
that could increase the possibility of 
injury from the ricochet of thrown objects.
