SECTION 1 - SAFETY PRECAUTIONS
3121272 – JLG Lift – 1-9
•Never attempt to use the machine as a crane. Do not tie-off
machine to any adjacent structure. Never attach wire, cable,
or any similar items to platform.
•Do not cover the platform sides or carry large surface-area
items in the platform when operating outdoors. The addi-
tion of such items increases the exposed wind area of the
machine.
•Do not increase the platform size with unauthorized deck
extensions or attachments.
•If the scissor arm assembly or platform is caught so that one
or more wheels are off the ground, all persons must be
removed before attempting to free the machine. Use
cranes, forklift trucks, or other appropriate equipment to
stabilize machine and remove personnel.
Crushing and Collision Hazards
•Approved head gear must be worn by all operating and
ground personnel.
•Keep hands and limbs out of the scissor arm assembly dur-
ing operation and when elevated without safety prop
engaged.
•Watch for obstructions around machine and overhead
when driving. Check clearances above, on sides, and bot-
tom of platform when lifting or lowering platform.

SECTION 1 - SAFETY PRECAUTIONS
1-10 – JLG Lift – 3121272
•During operation, keep all body parts inside platform rail-
ing.
•Always post a lookout when driving in areas where vision is
obstructed.
•Keep non-operating personnel at least 6 ft. (1.8m) away
from machine during all operations.
•Under all travel conditions, the operator must limit travel
speed according to conditions of ground surface, conges-
tion, visibility, slope, location of personnel, and other fac-
tors.
•Be aware of stopping distances in all drive speeds. When
driving in high speed, switch to low speed before stopping.
Travel grades in low speed only.
•Do not use high speed drive in restricted or close quarters
or when driving in reverse.
•Exercise extreme caution at all times to prevent obstacles
from striking or interfering with operating controls and per-
sons in the platform.
•Ensure that operators of other overhead and floor level
machines are aware of the aerial work platform’s presence.
Disconnect power to overhead cranes. Barricade floor area
if necessary.
•Do not operate over ground personnel. Warn personnel not
to work, stand, or walk under a raised platform. Position
barricades on floor as necessary.
