Changing the Impact Force

Impact force can be changed in three steps: Low (L), Middle (M), High (H). Pressing the button cycles through these settings, affecting the number of blows.

NOTE: 'A' mode (likely referring to a specific setting not fully detailed here) is available only when rotating clockwise. Counterclockwise rotation in 'A' mode uses the same impact force and speed as 'H' mode.

NOTE: When all lamps on the switch panel are off, the tool is in standby to save battery. Impact force grade can be checked by pulling the trigger slightly.

NOTE: Impact force grade cannot be changed while the switch trigger is pulled.

Reversing Switch Action

Use the reversing switch lever to change rotation direction.

CAUTION: Use the reversing switch only when the tool has completely stopped. Changing direction while moving may damage the tool.

CAUTION: When not operating, set the reversing switch lever to the neutral position. The switch trigger cannot be pulled in neutral.

• Clockwise Rotation: Depress lever from side A.
• Counter-clockwise Rotation: Depress lever from side B.
• Neutral: Lever in the middle position.

Assembly

Selecting Correct Impact Socket

Use the correct size impact socket for bolts and nuts. Incorrect sizes can lead to inaccurate torque or damage.

Installing or Removing Impact Socket

CAUTION: Ensure the impact socket and mounting portion are not damaged before installation.

CAUTION: After inserting the impact socket, ensure it is firmly secured. Do not use if it comes out.

• Align the hole in the socket with the detent pin on the square drive.

Operation Details

Fastening

CAUTION: Always insert the battery cartridge fully until it locks. Check the red indicator; if visible, it's not fully locked.

Hold the tool firmly. Place the impact socket over the bolt or nut. Turn the tool on and fasten for the proper time.

Proper fastening torque depends on bolt type/size, workpiece material, etc. Refer to figures for torque/time relation (not provided in OCR).

NOTE: Hold the tool pointed straight at the bolt or nut.

NOTE: Excessive torque can damage the bolt/nut or socket. Perform a test operation to determine proper fastening time.

NOTE: If the tool operates until the battery is discharged, let it rest for 15 minutes before using a new battery.

Fastening torque is affected by many factors. Always check torque with a torque wrench after fastening.

When the battery is nearly discharged, voltage drops, reducing fastening torque.

Impact Socket and Bolt Considerations

• Using the wrong size impact socket reduces fastening torque.
• Worn impact sockets (on hex or square end) reduce fastening torque.
• Proper fastening torque varies with bolt diameter, torque coefficient, bolt class, and length.
• Universal joints or extension bars can reduce fastening force; compensate with longer fastening time.
• Tool holding method and driving position material affect torque.
• Operating at low speed reduces fastening torque.
