Switch action
CAUTION:
• Before connecting the battery to the shears, always
check to see that the switch trigger actuates properly
and returns to the "OFF" position when released.
• Do not pull the switch trigger without depressing the
lock-off lever. It can cause switch breakage.
Switch on the controller by pressing the upper (I) side of
the switch. The pilot lamp will start to blink green. Then
pull the switch trigger and release it once. The upper
shear blade will start to move up as soon as you release
the switch trigger and will stop at the highest (wide open)
position. In case that the upper shear blade has already
opened, it will keep that position with the first trigger
operation. The pilot lamp will remain green continuously.
From the next trigger operation, you can cut branches.
(Fig. 4)
To prevent the switch trigger from being accidentally
pulled, a lock-off lever is provided. To start the shears,
depress the lock-off lever and pull the switch trigger. To
stop the shears, release the switch trigger. (Fig. 10)
When the switch trigger is pulled and held, the upper
shear blade will move down and stop at the closed posi-
tion. When the switch trigger is released, the upper shear
blade will move up and stop at the highest (wide open)
position. (Fig. 11)
Putting shears in holster (Fig. 12)
Switch off the controller by pressing the lower (O) side of
the switch while keeping the switch trigger pulled. The
upper shear blade will stop at the closed position. Put the
shears in the holster with the upper shear blade at the
closed position.
NOTE:
• Fasten the tool with holster belt.
Pruning operation (Fig. 13)
CAUTION:
• Never operate the shears in an awkward posture. This
may cause a serious injury.
• Never hold the branch you are pruning with your free
hand. Keep your free hand away from the cutting area.
The blades are very sharp and you may cut yourself.
Cut branches one by one as shown in Fig. 13. The maxi-
mum thickness of branches which can be cut with these
shears is about 30 mm. Maintain your proper footing and
balance at all times.
After use, switch off the controller and disconnect the
connection cord from the shears and the controller. Store
the shears in dry, high or locked-up place – out of reach
of children.
Overload protecting mechanism
Both the shears and the controller are equipped with an
overload protecting mechanism. If the motor is locked for
more than three seconds, this mechanism will actuate to
stop the shears. Also, the pilot lamp on the controller will
start to blink red and green alternately. To resume opera-
tion, switch off the controller by pressing the lower (O)
side of the switch, then switch it on again.
NOTE:
• Do not operate the shears in such a way that this
mechanism actuates frequently. The motor may be
damaged.

Pilot lamp on controller (Fig. 4)
The pilot lamp will start to blink or remain green when the
controller is switched on (the upper (I) side of the switch
is pressed). If the pilot lamp indicates the following condi-
tions, proceed as follows.
1. If the pilot lamp blinks red and green alternately, the
overload protecting mechanism has been actuated
or the connection cord is not firmly connected.
Switch off the controller and do the following:
a) If the motor is locked for more than three
seconds, just switch on the controller.
b) If the connection cord is not connected firmly,
connect the connection cord firmly and then
switch on the controller.
2. If the pilot lamp blinks red, the inside of the controller
is too hot. Switch off the controller and wait for a
while to cool it down. Then switch it on.
3. If the pilot lamp remains red continuously, the bat-
tery voltage is too low. Charge the battery.
4. If the pilot lamp is neither green or red:
a) The battery is completely discharged. Charge
the battery.
b) The overcurrent relay has actuated. Press the
restart button.
If the pilot lamp does not start to blink green even after
you perform the above procedures, there is something
wrong with the shears, connection cord, controller or bat-
tery. Switch off the controller and disconnect the connec-
tion cord from the shears and the controller. Remove the
controller from the battery. Send the shears, connection
cord, controller and battery to your dealer or a Makita
Service Center to have them inspected and/or repaired.
Replacing shear blades
CAUTION:
• Always be sure that the controller is switched off and
the connection cord is disconnected from the shears.
The shear blades can be replaced irrespective of the
upper shear blade position.
Use the hex wrench provided to remove the two hex
socket head bolts which secure the blade cover. (Fig. 14)
Remove the blade cover. (Fig. 15)
Use the socket wrench provided to remove the hex lock
nut. The flat washer will come off together with the hex
lock nut. (Fig. 16)
Remove the round head bolt, blade holder and upper
shear blade. (Fig. 17)
Remove the upper shear blade from the blade holder. Be
careful not to allow any foreign matter to attach to the
magnet on the blade holder and do not damage it.
(Fig. 18)
Use the hex wrench provided to remove the two hex
socket head bolts which secure the lower shear blade.
Then remove the lower shear blade. (Fig. 19)
To install the shear blades, follow the removal procedures
in reverse. Do not remove grease around the gear.
