WARNING
When LED lights RED, BP-T will stop fastening even
before reaching the preset target torque. Replace the
depleted battery with a fully charged one.
Charge a brand-new battery completely before first use. Ending battery
charging prematurely can cause the LED to incorrectly display remaining
capacity. If this happens, charge the battery fully a few times, and the LED
should display correct information.

15
Factors that can affect fastening torque
1 Work conditions
Fastening torque can vary even for bolts of the same diameter. The
transmitted torque can change depending on bolt grade, length,
coefficient 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, BP-T anvil, and fastener
Ensure that fit of the tool anvil to the driving socket and the socket
engagement to the fastener are tightly toleranced. Poor fit of the tool
anvil to the socket and/or poor fit 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 BP-T and socket
A universal joint, connector, or long socket that increases the distance
from the tool to the fastener can reduce torque transmission.
