Maintenance

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.

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)
