Grip installation is dangerous because it occurs within the crush zone of the
force train while full hydraulic pressure is applied and actuator movement is
required during the installation.
Unexpected actuator movement can cause personal injury and damage to
the equipment.
Take every precaution to avoid unexpected actuator movement while installing the
grips.
