TORQUE SETTING
By simply turning the adjusting screw with a hexagonal Allen wrench, precise
torque can be set.
①
The minimum torque value is set for shipment. The top surface of the adjustable screw is
adjusted to the minimum torque
（

）
printed on the nameplate. This is the
base tightening quantity.
②
Before setting the torque, apply Loctite 242 or an equivalent adhesive to the exposed
surface of the adjustable screw’s thread portion. After setting torque, it becomes
anti-loosing.
③
From the “Tightening Amount
-
Torque Correlation Chart”, find the adjusting screw
tightening angle equivalent to the predetermined trip torque. Set at 60°toward the
determined tightening value, then install to the machine and conduct a trip torque. Each
product’s trip torque does not always correspond with the value listed in the “Tightening
Amount-
Torque Correlation Chart”,
so use these values only as a rough guide.(Table 6 and
Fig.8)
④
Do not set torque lower than the minimum torque
（

）
.
If it is necessary to use a torque level lower than the minimum, use a weak spring type.
⑤
Do not turn the adjusting screw when the Shock Guard is in a tripped state.
⑥
Torque setting before shipment is available.
