• 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 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
during operation.
• Watch for obstructions around machine and overhead
when driving. Check clearances above, on sides, and bot-
tom of platform when lifting or lowering platform.
• 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 1.8m. (6 ft.) away
from machine during all driving 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 causing hazards of collision or injury to personnel.
