NOTE:
If you connect or disconnect the connection cord with
the controller switched on, the pilot lamp will blink red
and green alternately. When this occurs, the shears
will not start even if you pull the switch trigger. Switch
off the controller and then switch it on again to start
the shears. (Fig. 4)
Switch action
CAUTION:
• Before connecting the battery to the shears, always
check to see that the switch trigger actuates prop-
erly 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
position. 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.
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
maximum 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 alter-
nately. To resume operation, 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 conditions, 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
battery 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 some-
thing wrong with the shears, connection cord, control-
ler or battery. Switch off the controller and disconnect
the connection cord from the shears and the control-
ler. 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)
