REPLACING THE BLADE

The blade is a consumable that has to be replaced with a
new blade when it loses sharpness.
Follow the steps below to replace the blade.
The tool shown in the illustration is the shrub shear, and
it is used in examples to explain features it shares with
the grass shear.
Before replacement, turn the switch on and off until the
teeth in the upper blade are positioned over the openings
between the teeth in the lower blade.
At this time, be careful of the moving blade.
WARNING
Be sure to turn off the power switch and remove the
battery from the tool to prevent accidents.
CAUTION
Before blade replacement, be sure to use gloves and
attach the blade case or blade cover to prevent the
blade from coming into direct contact with your hands
or face.
1. Remove the blade (Fig. 13)
(1) Turn the tool over, remove the four screws using a
Phillips screwdriver, remove the bottom plate and
the blade (with blade case).
(2) Remove the remaining crank holder and crank cam
(A) from the tool. The grease used may cause the
crank holder and crank cam (A) to stick to the blade.
(3) Remove any chips and other debris from inside the
housing.
2. Getting a new blade ready
Taking care to prevent injury from contact with the
blade, adjust the crank cam position as shown in
Fig. 14.
This places the teeth in the upper blade over the
openings in the teeth in the lower blade.

3. Attach the crank cam and crank cam holder to the
blade (Fig. 15)
The same type of crank cam holder is used in the
shrub shear and the grass shear. Use the crank holder
installed in the product.
4. Attach the new blade
(1) Align the pin on the tool with the center hole in the
crank holder. (Fig. 16)
(2) When the hexagonal part in the crank holder and the
grooves in the gear do not align, fine adjust so that the
crank holder aligns with the gear grooves. (Fig. 17)
(3) Turn over the tool making sure that the blade does
not fall out, attach the bottom plate and secure it with
the 4 screws. (Fig. 18)
NOTE
Be sure to check blade operation after it has been
attached. The blade and the crank cam has not been
properly fitted if the blade does not operate correctly.
Do the instructions over from the beginning.

HOW TO USE

WARNING
To prevent accidents, make sure there are no people
in the work area.
Keep your hands and all parts of the body away from
the blade to prevent contact that could lead to injury.
Use protective goggles during work to prevent injury
from twigs and wood chips.
Do not use to tool to cut wire, metal plates or other hard
objects. The tool could be damaged and cause injury.
1. Trimming hedges and garden trees [Shrab shear]
CAUTION
Use a pair of pruning shears to cut thick branches
before using the shrub shear.
Do not force the tool to prevent it from breaking.
Stop the tool immediately if the blade stalls against a
too heavy branch. Do not allow the motor to seize up
as it could damage the motor.
Use a sturdy ladder or step ladder when cutting tall
garden trees.
Use only for cutting shrub.
(1) Clear the area around the garden tree you want to
prune and set up a stable platform to work from.
(2) Place the blade in the blade case to prevent accidental
contact.
(3) Install the battery in the tool.
(4) Press the Lock Off button and pull back the switch to
start trimming.
NOTE
Lubricate (using sewing machine oil, mineral oil, etc.)
the blade before starting and then every hour. Use an
adequate amount of oil and wipe away excess oil.
During work (for example, when taking rests) do not
leave the tool in a place exposed to direct sunlight or
high temperature. This will prevent proper cooling
and could result in damage.
Do not use the tool for work that exceeds its capacity.
Such operation could cause the motor to lock up or
slow down and will damage it.
Trimming garden trees
Use a pair of pruning shears to remove 10 cm of
branches that are 8 mm or thicker so that they do not
interfere with trimming. (Fig. 20)
