5.5 FACTORS THAT CAN AFFECT HANDLING TORQUE
1. Working conditions
Fastening torque can vary even for bolts of the same diameter.
The transmitted torque can change depending on bolt grade,
length, coefcient determined by bolt quality/work condition,
condition of bolt seating, and distance between fasteners. Torque
transmission can also be affected if the bolt and nut rotate
together even after fastening.
2. Engagement gap among socket, UBX, and fastener
Ensure that t of the tool anvil to the driving socket and the socket
engagement to the fastener are tightly toleranced. Poor t of the
tool anvil to the socket and/or poor t of the socket to the fastener
will result in inaccurate torque delivery to the tightened joint.
3. Trigger
Keep trigger fully squeezed until the tool automatically shuts off.
Early release of the trigger can cause automatic shut-off to fail.
4. Low torque posed by inclusion between UBX and socket
A universal joint, connector, or long socket that increases the
distance from the tool to the fastener can reduce torque
transmission.

When to replace the battery pack
Depending on work conditions, the battery pack will perform
approximately 500 charge/discharge cycles. It is time to replace
the battery pack with a new one when the length of charge life
decreases to half despite an initial full charge.
Battery pack storage
Store lithium-ion battery packs without charge after use. Remove
any foreign matter from terminals. Cover battery using pack cover,
which helps avoid short circuits and protects terminals from debris.
Do not store batteries in a hot or humid place.
Battery pack recycling
The Lithium-ion battery pack is recyclable, and should not be
mixed with general household waste. Return used battery packs to
the distributor who sold them to you. Cover terminals of the battery
pack with insulating tape to avoid short circuit for return shipment.
