rear handle and the left hand on the front handle.

RBC30SBSB:

Hold the trimmer with the right hand on the

trigger handle and the left hand on the left handle.

Keep a firm grip with both hands while in operation. Trimmer
should be held at a comfortable position with the trigger
handle about hip height.

Always operate trimmer at full throttle. Cut tall grass
from the top down. This will prevent grass from wrapping
around the shaft housing and string head which may
cause damage from overheating. If grass becomes
wrapped around the string head, stop the engine,
disconnect the spark plug wire, and remove the grass.
Prolonged cutting at partial throttle will result in lubricant
dripping from the silencer.

CUTTING TIPS (Fig. 6)

When cutting, make sure the cutter head is at a slight
angle as shown while still approximately parallel to the
ground surface. In tall grass, cut from the top down to
ensure the moving parts do not get tangled with the long
grass / brush.
Move the head in steady strokes from left to right as you
work through the grass / brush.

ADVANCING THE LINE (Fig. 7)

FOR REELEASY

ONLY

If the line becomes short, tap the head on the ground
as shown to extend more line. Take care not to ‘crash’ it
against a hard surface.

OPERATING THE BRUSHCUTTER (Fig. 5)

RBC30SESB:

Hold the brushcutter with the right hand on

the rear handle and the left hand on the front handle.

RBC30SBSB:

Hold the brushcutter with the right hand on

the trigger handle and the left hand on the left handle.

Keep a firm grip with both hands while in operation.
Brushcutter 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
cutting blade.

Adjust the shoulder strap to position the brushcutter at
a comfortable operating position and to assure that the
shoulder strap will reduce the risk of operator contact
with the blade.

Exercise extreme caution when using the blade
with this unit. Blade thrust is the reaction which
may occur when the spinning blade contacts
anything it cannot cut. This contact may cause

the blade to stop for an instant, and suddenly
“thrust” the unit away from the object that was hit.

This reaction can be violent enough to cause the
operator to lose control of the unit. Blade thrust may
occur without warning if the blade snags, stalls or binds.
This is more likely to occur in areas where it is difficult to
see the material being cut. For cutting ease and safety,
approach the weeds being cut from the right to the left.
In the event that an unexpected object or woody stock is
encountered, this could minimise the blade thrust reaction.

WARNING

Extreme care must be taken when using blades

to ensure safe operation. Read the safety
information for safe operation using the blade,
refer to “Specific Safety Rules for Brushcutter
and Blade Use” earlier in this manual.

MAINTENANCE

WARNING

Use only original manufacturer's replacement

parts, accessories and attachments. Failure to
do so can cause possible injury, poor perfor-
mance and may void your warranty.

■

The cutting attachment must not work in idle mode.
If this requirement is not satisfied, the clutch has
to be adjusted or the machine needs an urgent
maintenance by a qualified technician.

■

You may make adjustments and repairs described
here. For other repairs, have the trimmer serviced by
an authorized service agent.

■

Consequences of improper maintenance may
include excess carbon deposits resulting in loss of
performance and discharge of black lubricant residue
dripping from the muffler.

■

Make sure all guards, straps, deflectors and handles
are properly and securely attached to avoid the risk of
personal injury.
