Maintenance - Honda UMK425E1 Owner's Manual

WITH 3-TOOTH AND 4-TOOTH
BLADE
CAUTION:
• Do not use a blade larger than
255 mm in diameter.
CUTTING
The 3-tooth and 4-tooth grass-
cutting blade is especially
suitable for clearing dense and
tangled weeds, bushes such as
brambles or wild shrubs with a
stem diameter of less than 2 cm.
To trim bushes, lower the cutting
attachment from above while
holding it horizontal so as to cut
the branches in small pieces.
It is dangerous to use grass-
cutting blades on very hard
wood and/or plants with a
large stem diameter. Kicking
of the cutting attachment is
difficult to control, and can seriously endanger the operator
and cause serious damage to the equipment.
WITH CIRCULAR SAW BLADE
Use of the circular saw blade is only authorized on UMK435E1
of type UEET.
CAUTION:
• Never use a saw blade with a diameter in excess of 200 mm. The
circular saw blade is intended to be used for cutting out shrubs,
bushes and small trees whose trunk does not exceed 6 cm in
diameter.
CUTTING
Some blade sectors [1] must
not be used as they will cause
the tool to rebound owing to
the direction of rotation.
Tools fitted on Honda
brushcutters rotate
counterclockwise. It NEVER
cut with the right half of the
blade. The part to be used is represented by the grey area.
For the best results, you must swing your equipment quickly
towards the branch or trunk to be cut. Do not proceed gradually as
engine speed could drop and lead to stalling.
Estimate the height of the items to be cut and where they might
fall.
Ensure that falling pieces will not cause bodily injuries to
persons or property damage.
Make sure the blade is not stuck in the trunk when it falls.
Always cut on the side opposite the fall.

Sharpening is essential to obtain good results. A slightly blunt
cutting attachment can be sharpened with a file.
A grinding wheel should be used if the wear is more severe.

balanced. If you do not have the required tools or if you think your
cutting attachment may not be properly balanced, contact your
