SECTION 2. USER RESPONSIBILITIES, MACHINE PREPARATION AND INSPECTION
2.1
PERSONNEL TRAINING
The aerial platform is a personnel handling device; so it is necessary that it be operated and maintained only by trained personnel.
Persons under the influence of drugs or alcohol or who are subject to seizures, dizziness or loss of physical control must not operate this machine.
Operator Training
Operator training must cover:
1. Use and limitations of the controls in the platform and at the ground, emergency controls and safety systems.
2. Control labels, instructions, and warnings on the machine.
3. Rules of the employer and government regulations.
4. Use of approved fall protection equipment.
5. Enough knowledge of the mechanical operation of the machine to recognize a malfunction or potential malfunction.
6. The safest means to operate the machine where overhead obstructions, other moving equipment, and obstacles, depressions, holes, drop-offs.
7. Means to avoid the hazards of unprotected electrical conductors.
8. Specific job requirements or machine application.
Training Supervision
Training must be done under the supervision of a qualified person in an open area free of obstructions until the trainee has developed the ability to safely control and operate the machine.
Operator Responsibility
The operator must be instructed that he/she has the responsibility and authority to shut down the machine in case of a malfunction or other unsafe condition of either the machine or the job site.

5.
“Walk-Around” Inspection – Refer to Figure 2-1.,
Walk-Around Inspection (Sheet 1 of 3).
6.
Battery – Charge as required.
7.
Fuel - (Combustion Engine Powered Machines) – Add the proper fuel as necessary.
8.
Engine Oil Supply - Ensure that the engine oil level is at the full mark on the dipstick and the filler cap is secure
9.
Fluid Levels - Be sure to check the engine oil and the hydraulic oil levels.
10.
Accessories/Attachments - Reference the Operator and Safety Manual of each attachment or accessory installed upon the machine for specific inspection, operation, and maintenance instructions.
11.
Function Check – Once the “Walk-Around” Inspection is complete, perform a functional check of all systems in an area free of overhead and ground level obstructions. Refer to Section-4 for more specific instructions on the operation of each function.

Preparing the Machine for Operation
Emergency Ground Control Station
1. Turn key-switch to ground control select.
2. Pull emergency stop switch to the On position.
3. Check the function of the protective scissor cage.
Platform Control Box
1. Ensure the control box is connected at the platform.
2. Complete pre-operational checks:
a. Check all functions
b. Machine should not be drivable with outriggers extended.
c. Check all limit switches
d. Check the emergency-STOP button
e. Check the automatic self levelling
IF THE MACHINE DOES NOT OPERATE PROPERLY, TURN OFF THE MACHINE
IMMEDIATELY! REPORT THE PROBLEM TO THE PROPER MAINTENANCE PER-
SONNEL. DO NOT OPERATE THE MACHINE UNTIL IT IS DECLARED SAFE FOR
OPERATION.
Function Check
Perform the Function Check as follows:
1. From the ground emergency control panel with no load in the platform:
a. Check for proper lifting and lowering of the platform.
b. Check manual descent.
c. Ensure that all machine functions are disabled when the Emergency Stop Button is activated.
NOTE:
Be sure the platform extension is retracted before lowering.
2. From the platform control console:
a. Ensure that the control console is firmly secured in the proper location.
b. Check that all guards protecting the function control switches are in place.
c. Check the high drive cut out switch by raising the platform beyond the preset high drive speed cutout height (stowed) and ensure the high drive speed cuts out.
d. Ensure that all machine functions are disabled when the Emergency Stop Button is pushed in.

e. Ensure that all LED’s in the control box are working properly.
f. Check that the platform extension extends and retracts properly.
3. With the platform in the stowed position:
a. Drive the machine on a grade, not to exceed the rated gradeability, and stop to ensure the brakes hold.
b. The red warning LED on the control panel indicates the chassis is on a slope beyond the rated limit from side to side and/or front to rear when the platform is in the stowed position.
