Factors affecting bolt tightening
torque
Bolt tightening torque varies due to factors
described below.
1) Tightening time
Longer tightening time results in increased
tightening torque. Excessive tightening,
however, adds no value and reduces the
life of the tool.
) Bolt
• Bolt diameter: Tightening torque gener-
ally increases with bolt diameter.
• Torque coefficient (indicated by the bolt
manufacturer), grade, length, etc.
3) Battery pack charge status
• Tightening torque decreases as the bat-
tery is discharged.
• Tightening torque decreases rapidly as
the battery nears the end of its charge.
(The product's automatic power-off func-
tion will engage once the battery's charge
is exhausted.)

4) Other
• Bit and socket condition: Material, amount
of play, etc.
• Use of a universal joint or socket adapter.
• User: Manner in which the tool is applied
to the bolt, strength with which the tool is
held, manner in which the tool's switch is
engaged.
• Condition of object being tightened: Mate-
rial, seating surface finish.
[Battery Pack]
For Appropriate Use of Bat­
tery Pack
Li­ion Battery Pack (EYFB30)
• For optimum battery life, store the Li-ion bat-
tery pack following use without charging it.
• When charging the battery pack, confirm
that the terminals on the battery charger
are free of foreign substances such as dust
and water etc. Clean the terminals before
charging the battery pack if any foreign sub-
stances are found on the terminals.
The life of the battery pack terminals may be
affected by foreign substances such as dust
and water etc. during operation.
• When battery pack is not in use, keep it
away from other metal objects like: paper
clips, coins, keys, nails, screws, or other
small metal objects that can make a con-
nection from one terminal to another.
Shorting the battery terminals together may
cause sparks, burns or a fire.
• When operating the battery pack, make sure
the work place is well ventilated.
• When the battery pack is removed from the
main body of the tool, replace the battery
pack cover immediately in order to prevent
dust or dirt from contaminating the battery
terminals and causing a short circuit.
Battery Pack Life
The rechargeable batteries have a limited life.
If the operation time becomes extremely short
after recharging, replace the battery pack with
a new one.
