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

NOTE:Excessivefasteningtorquemaydamagethe

bolt/nutorimpactsocket.Beforestartingyourjob,

alwaysperformatestoperationtodeterminethe

properfasteningtimeforyourboltornut.

NOTE:Ifthetoolisoperatedcontinuouslyuntilthe

batterycartridgehasdischarged,allowthetooltorest

for15minutesbeforeproceedingwithafreshbattery

cartridge.

Thefasteningtorqueisa󰀨ectedbyawidevarietyof

factorsincludingthefollowing.Afterfastening,always

check the torque with a torque wrench.

1. Whenthebatterycartridgeisdischargedalmost

completely,voltagewilldropandthefastening

torque will be reduced.

2. Impact socket

• Failure to use the correct size impact socket

will cause a reduction in the fastening torque.

• Awornimpactsocket(wearonthehexend

orsquareend)willcauseareductioninthe

fastening torque.

3. Bolt

• Eventhoughthetorquecoe󰀩cientandthe

class of bolt are the same, the proper fasten-

ingtorquewilldi󰀨eraccordingtothediame-

ter of bolt.

• Even though the diameters of bolts are the

same,theproperfasteningtorquewilldi󰀨er

accordingtothetorquecoe󰀩cient,theclass

of bolt and the bolt length.

4. The manner of holding the tool or the material

ofdrivingpositiontobefastenedwilla󰀨ectthe

torque.

5. Operating the tool at low speed will cause a reduc-

tion in the fastening torque.
