4 TROUBLESHOOTING GUIDE

(Refer to WIRING CONNECTION DIAGRAM)

< TROUBLE >

Does not operate.

→

<CHECK >

<CHECK BATTERY PACK.>

If no less than 18V DC is available across the (+) and (-) terminals, the battery pack is OK.

NOTE: The battery pack is sold separately as an optional accessory. See the nearest sales dealer for details. The battery pack has a limited life.

The pack should be replaced if

-after being charged for the rated charging time the battery voltage is less than 18V DC or the usable time is extremely short.

-the battery leaks. Check battery for leaks and terminals for corrosion.

↓OK

<CHECK TERMINAL CONNECTIONS BETWEEN MAIN UNIT

AND BATTERY PACK.>

Check for proper terminal contacts.

↓OK

<REMEDY >

NO Replace battery pack.

→

NO Repair contacts.

→

Does not speed- control.

<CHECK SWITCH BLOCK.>

(See WIRING CONNECTION DIAGRAM.)

Check continuity between following terminals.

*Inspection of the forward / reverse selection switch. When switch handle is depressed all the way:

-There should be 0Ω between (A) - (D) , and between (B) - (C) ; when switch lever is set to forward side.

-There should be 0Ω between (A) - (C) , and between (B) - (D) ; when switch lever is set to reverse side.

↓OK

<CHECK MOTOR.>

The motor normally operates with its white (+) and black (-) lead wires connected to 18V DC.

<CHECK FET.>

Even if FET block is defective, it can not be replaced individually. Replace whole switch block.

Remove the FET circuit block and check the lead wire terminals. These terminals are open normally when there is an open circuit ( Ω) between the green and yellow lead wires, and between the blue and yellow lead wires.

NOTE:

*FET is weak against static electricity.

**The resistance value may be some differences depends on the measurement range.

NO Contacts in switch block

→are defective. Replace switch & FET block.

NO Replace motor.

→

NO Repair the contact

→or replace switch & FET block.
