Torques
The SG-42 and SG-44 spray guns have angled lances, which generate a torque. In
accordance with DIN EN 60335, a maximum torque of 20 Nm is permissible on the
spray gun grip. The user is more limited by this torque than by the reaction force.
Therefore, with SG-42 and SG-44 spray guns, you must pay attention to the torque
table.

Calculating the torque on the SG-42 grip
To calculate:
T
= torque [Nm]
Given:
F
= reaction force [N]
= 70 N
l
= length [m]
= 1.05 m
