REACTION
1. Select correct socket drive: it is recommended to use
power drive 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.
4. An extension driver up to 9" (250 mm)
long may be used but ensure that:
 Output torque does not exceed
1000 N·m (750 lbf·ft)
 Reaction forces are taken at the end
of the reaction arm/bar.
DRIVING TOOL
1. For torque control and even bolt loading a torque
wrench is required.
2. Set torque wrench to one fifth of the desired
torque on the nut. Do not exceed maximum input
torque.
IMPORTANT: DO NOT USE THE MULTIPLIER
WITH IMPACT OR IMPULSE
WRENCHES.
