Trouble

Probable cause

Action

The tool does not operate.

The motor is over-heated.

Wait until the motor cools down and the LED switches
off

The battery pack is over-discharged.

The battery voltage falls below a certain level and
protective function is activated.

Charge the battery pack.

Be sure to charge the over-discharged battery pack

to full level. If the charging level is not sufficient, the
protective function may not be released.

The battery pack gives a low voltage output.

Replace the battery pack.

 

Low voltage error may occur when the

battery pack, with degraded performance owing to

the deterioration, low temperature etc., is used.

Normally, the over-discharge protection inside the

battery pack is activated, so the low voltage error will
not occur

The tool is in a setting mode.

PC-1 is connected and is in Setting mode, detach the
battery pack and disconnect the PC-1.

Following error is outputted:

Commutation Error

Motor lock Error

Wire breakage error of motor

temperature sensor

Wire breakage error of driver

temperature sensor

Over-voltage Error

Over-current Error

Abnormal pulse signal

Memory Error

Please send the tool for repair to an authorized
service shop.

 

 Extreme low environment temperature can show a

wire breakage error or  motor/driver temperature
sensor error causing motor lock. Confirm the proper
ambient temperature.

When releasing the throttle lever during no-load
rotation,  there is a stop sound from the motor.

It is the operating sound of the brake when stopping.

It is not a problem. Continue to use as it is.

Overheat alarm frequently occurs.

The load on the tool is big, number of cycles per
minute is too high.

Use the tool at  tightening application within the limits
of the tool.

The cooling fan is broken down.

Please send the tool for repair to an authorized
service shop.

 

The number of cycles is small despite a fully charged
battery pack.

It is the end of life of the battery.

Replace the battery.

LED on the battery charger is not indicating while
charging the battery.

Dirt adheres to the terminals of the battery charger
and the battery.

Clean the terminals after unplugging the power cord.

Stand-by lamp (orange) for the battery charger blinks

The temperature of the battery is too high or too low.

Charge the battery pack in a location at ambient
