JLG 1930ES Operation & Safety Manual page 11

• Use extreme caution when entering or leaving plat-
form. Ensure that the scissor arm assembly is fully low-
ered. Face the machine when entering or leaving the
platform. Always maintain "three point contact" with
the machine, using two hands and one foot or two feet
and one hand at all times during entry and exit.
• Platform-to-structure transfers at elevated positions are
discouraged. Where transfer is necessary, enter/exit
through the gate only with the platform within 1 foot
(0.3m) of a safe and secure structure. 100% tie-off is
also required in this situation utilizing two lanyards.
One lanyard must be attached to the platform with the
second lanyard attached to the structure. The lanyard
connected to the platform must not be disconnected
until such time the transfer to the structure is safe and
complete.
• Keep oil, mud, and slippery substances cleaned from
footwear and the platform floor.
Electrocution Hazards
• This machine is not insulated and does not provide
protection from contact with an electrically charged
conductor.
• Maintain safe clearance from electrical lines, appara-
tus, or any energized (exposed or insulated) parts in
accordance with the Minimum Safe Approach Distance
(MSAD) as specified in Table 1-1. Allow for machine
movement and electrical line swaying.

• Maintain a clearance of at least 10 ft. (3m) between any
part of the machine and its occupants, their tools, and
their equipment from any electrical line or apparatus
carrying up to 50,000 volts. One foot additional clear-
ance is required for every additional 30,000 volts or
less.
DO NOT MANEUVER MACHINE OR PERSONNEL INSIDE PROHIB-
ITED ZONE (MSAD). ASSUME ALL ELECTRICAL PARTS AND WIR-
ING ARE ENERGIZED UNLESS KNOWN OTHERWISE.
Tipping Hazards
• Ensure that the ground conditions are adequate to
support the maximum tire load indicated on the tire
load decals located on the chassis adjacent to each
wheel. Do not travel on unsupported surfaces.
• The user should be familiar with the driving surface
before driving. Do not exceed the allowable sideslope
and grade while driving.
