Theproperfasteningtorquemaydifferdependingupon
thekindorsizeofthescrew/bolt,thematerialofthe
workpiecetobefastened,etc.Therelationbetweenfas-

Holdthetoolrmlyandplacethepointofthedriverbit
inthescrewhead.Applyforwardpressuretothetoolto
theextentthatthebitwillnotslipoffthescrewandturn
the tool on to start operation.
NOTICE: If you use a spare battery to continue
the operation, rest the tool at least 15 min.
NOTE:Usetheproperbitfortheheadofthescrew/
bolt that you wish to use.
NOTE:WhenfasteningM8orsmallerscrew,carefully
adjustpressureontheswitchtriggersothatthescrew
is not damaged.
NOTE: Hold the tool pointed straight at the screw.
NOTE: If the impact force is too strong or you tighten
thescrewforatimelongerthanshowninthegures,
the screw or the point of the driver bit may be over-
stressed, stripped, damaged, etc. Before starting your
job,alwaysperformatestoperationtodeterminethe
proper fastening time for your screw.
Thefasteningtorqueisaffected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. Driver bit or socket bit
Failure to use the correct size driver bit or socket
bitwillcauseareductioninthefasteningtorque.
3. Bolt
• Eventhoughthetorquecoefcientandthe
class of bolt are the same, the proper fasten-
ingtorquewilldifferaccordingtothediame-
ter of bolt.
