OPERATION

Using Blades
Refer to the chart on page 9 for appropriate blade
applications.
If using a blade on a Honda trimmer equipped
with a loop handle, also install the optional Honda
conversion kit that includes a full shoulder
harness, a barrier bar, and a debris shield for
blades. Follow the installation instructions and
safety information that come with the kit.
Metal blades supplied with UNBA models are
supplied with a cover surrounding the edge of the
blade. For your safety, and to protect the blade,
the cover should be installed whenever the
trimmer is not in use.
Be sure to remove the blade cover before starting
the engine. Otherwise, the blade cover may fly off
at high speed.
If the trimmer starts to vibrate after the blade
strikes an object, stop the engine immediately
and check the blade for damage. A damaged
blade may break, and pieces of broken blade can
become dangerous projectiles. Replace the
blade if it is broken, cracked, bent, or damaged in
any way.
SAFE OPERATING PRACTICES
Be very careful when operating the trimmer over
uneven or rough ground, and when the ground is
wet and slippery. Watch out for hidden obstacles
that could cause you to stumble. Operate the
trimmer only under conditions with good visibility.
Do not operate the trimmer where you cannot
see what it is cutting.
Thrown Debris
The trimmer will throw debris in the direction of
blade movement at the point of contact.
The cutting line head or blade on Honda HHT25S
and HHT31S trimmers rotate counterclockwise,
as viewed from the operator’s position, so tilting
the cutting line head to the right will throw debris
away from you, and tilting to the left will throw
debris toward you.
If the cutting line head or blade is held parallel to
the ground, debris will scatter in all directions,
and there will be greater friction which will wear
out the cutting line or blade sooner.
When operating the trimmer near a hard surface
such as a wall, work from an angle where debris
that strikes the hard surface will ricochet away
from you.
Gravel, loose stones, etc. can be picked up by
the nylon cutting lines or blade and thrown many
feet with enough force to cause serious personal
injury and/or property damage. Before crossing
graveled areas, release the throttle trigger to stop
the cutting line head or blade.
 WARNING
Rotating cutting lines can cause serious
abrasions and cuts, and blades can cut deeply.
• Keep away from the cutting lines or blade
whenever the engine is running.
• Always stop the engine, and be sure the
cutting line head has stopped turning,
before inspecting or handling the cutting
lines or blade.
DEBRIS
Cut with the right
side to throw debris
away from you.
