1-6 – JLG Lift – 3121170
SECTION 1 - SAFETY PRECAUTIONS
• The minimum approach distance may be reduced if insulating
barriers are installed to prevent contact, and the barriers are
rated for the voltage of the line being guarded. These barriers
shall not be part of (or attached to) the machine. The minimum approach distance shall be reduced to a distance within
the designed working dimensions of the insulating barrier.
