Blade Thrust
“Blade thrust” is a sudden sideways or
backward motion of the brushcutter.
Such motion may occur when the blade
jams or catches on an object such as a
sapling tree or tree stump. BE CON-
STANTLY ALERT FOR BLADE
THRUST AND GUARD AGAINST ITS
EFFECTS!
The blade rotates counter-clockwise.
For best performance and to minimize
being stuck by debris, move the blade
from right to left while advancing on
your work. Position the blade so cuts
are made between the blade’s 8 o’clock
and 10 o’clock positions (as viewed
from above). DO NOT cut between the
10 o’clock and 5 o’clock positions.
WARNING!
When cutting wood with
a blade, feed the blade slowly—
never strike or “slam” a spinning
blade against the wood.
WARNING!
DO NOT use 2-tooth or
non-Shindaiwa approved 4-tooth
cutting blades with Shindaiwa trim-
mers and brushcutters.
Using a blade
WARNING!
Blade thrust can occur with-
out warning if the blade snags,
stalls or binds.
WARNING!
Blade thrust is more likely to
occur in areas where it is difficult to
see the material being cut.

Brushcutter Handlebar
A brushcutter handlebar or barrier bar
helps prevent the operator from moving
forward, or the unit moving rearward,
thus preventing inadvertent bodily con-
tact with the blade. ALWAYS KEEP
THE HANDLEBAR OR BARRIER BAR
SECURELY IN PLACE ON THE UNIT!
WARNING!
Before performing any main-
tenance, repair, or cleaning work on
the unit, make sure the engine and
cutting attachment are completely
stopped. Disconnect the spark plug
wire before performing service or
maintenance.
WARNING!
Non-standard accessories, cut-
ting attachment, or replacement parts
may not operate properly with your unit
and may cause damage and lead to
personal injury.
IMPORTANT!
MAINTENANCE, REPLACEMENT OR REPAIR OF EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY
ANY REPAIR ESTABLISHMENT OR INDIVIDUAL; HOWEVER, WARRANTY REPAIRS MUST BE PERFORMED BY A DEALER
OR SERVICE CENTER AUTHORIZED BY ECHO, INC. THE USE OF PARTS THAT ARE NOT EQUIVALENT IN PERFOR-
MANCE AND DURABILITY TO AUTHORIZED PARTS MAY IMPAIR THE EFFECTIVENESS OF THE EMISSION CONTROL
SYSTEM AND MAY HAVE A BEARING ON THE OUTCOME OF A WARRANTY CLAIM.
General maintenance
NOTE:
Using non-standard replacement parts could invalidate your Shindaiwa warranty.
Engine Operating Speeds
Operate the unit at full throttle while cut-
ting. Best fuel efficiency is obtained by
releasing the throttle when swinging
back after a cut.
■
To prevent possible engine damage,
do not allow the brushcutter to run
at high speeds without a load.
■
Avoid operating the engine at low
speeds. Doing so can lead to rapid
clutch wear. In addition, slow-speed
operation tends to cause grass and
debris to wrap around the cutting
head.
