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.

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.

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.

If the pilot lamp remains red continuously, the bat-

tery voltage is too low. Charge the battery.

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.

MAINTENANCE

CAUTION:

• Always be sure that the controller is switched off and

the connection cord is disconected from the shears.

• Never use gasoline, benzine, thinner, alcohol or the

like. Discoloration, deformation or cracks may result.

Blade maintenance (Fig. 20 & 21)

NOTE:

• Before and after operation, check the shear blades

carefully.

After operation, clean off the blades with a stiff brush.

Then wipe the blades with a cloth and coat them with

machine oil.

CAUTION:

• Failure to perform blade maintenance may cause

excessive blade friction and shorten the operating time

per battery charge.

Sharpening blades

Upper shear blade

Apply the flat surface of the diamond file to the blade

edge. Push the diamond file in the direction of the arrow

to sharpen along the entire blade edge. Maintain the

same flat contact with the file consistently along the

entire blade edge. (Fig. 22)

Apply the flat surface of the diamond file lightly to the

reverse side of the blade. Move the diamond file in the

direction of the arrow to remove burrs. (Fig. 23)

Lower shear blade

Apply the round surface of the diamond file to the blade

edge. Push the diamond file in the direction of the arrow

to sharpen along the entire blade edge. (Fig. 24)

Apply the flat surface of the diamond file lightly to the

opposite side of the blade. Move the diamond file in the

direction of the arrow to remove burrs. (Fig. 25)

To maintain product safety and reliability, repairs, mainte-

nance or adjustment should be carried out by Makita

Authorized Service Center.
