REACTION
1. Select correct socket drive: it is
recommended to use impact sockets.
2. In use the tool body rotates in the
opposite direction to applied drive. It is
necessary to allow the torque reaction
arm to rest against a solid stop before
any useful work can be done.
3. To prevent undue stress on the gears
always take torque reaction as far away
from drive square as circumstances
permit.
There is a risk of crushing between the reaction bar and work piece.
Keep hands away from reaction bar.
Keep hands away from tool output
DRIVING TOOL
1. For torque control and consistent bolt
loading, a torque wrench is required.
2. A) With straight reaction - set torque
wrench to 1/5 of the desired torque on
the nut
B) With cranked reaction – set torque
wrench to 1/4.75 of the desired torque
on the nut
Do not exceed maximum input torque.
IMPORTANT:
HT3 is a precision tool which multiplies the input torque by a
