SECTION 1 - SAFETY

SECTION 1. SAFETY

1.1GENERAL

This section outlines the necessary precautions for towing and also proper and safe machine operation and maintenance. For proper machine use, it is mandatory that a daily routine is established based on the content of this manual. A maintenance program, using the information provided in this manual and the Service and Maintenance Manual, must also be established by a qualified person and followed to ensure the machine is safe to operate.

An owner’s manual that provides general trailer information cannot cover all of the specific details necessary for the proper combination of every trailer, tow vehicle and hitch. Therefore, you must read, understand and follow the instructions given by the tow vehicle and trailer hitch manufacturers, as well as the instructions in this manual.

The owner/user/operator/lessor/lessee of the machine should not operate the machine until this manual has been read, training is accomplished, and operation of the machine has been completed under the supervision of an experienced and qualified operator.

If there are any questions with regard to safety, training, inspection, maintenance, application, and operation, please contact JLG Industries, Inc. (“JLG”).

FAILURE TO COMPLY WITH THE SAFETY PRECAUTIONS LISTED IN THIS MANUAL COULD RESULT IN MACHINE DAMAGE, PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

Operator Training and Knowledge

•Read and understand this manual before towing or operating the machine.

•Do not tow or operate this machine until complete training is performed by authorized persons.

•Only authorized and qualified personnel can operate the machine.

SECTION 1 - SAFETY

•Do not operate this machine until it has been serviced and maintained according to requirements specified in the Service and Maintenance Manual.

•Be sure the enable trigger and all other safety devices are operating properly. Modification of these devices is a safety violation.

MODIFICATION OR ALTERATION OF AN AERIAL WORK PLATFORM SHALL BE MADE ONLY WITH WRITTEN PERMISSION FROM THE MANUFACTURER

•Do not operate any machine on which safety or instruction placards or decals are missing or illegible.

•Check the machine for modifications to original components. Ensure that any modifications have been approved by JLG.

•Avoid any buildup of debris on the platform floor. Keep mud, oil, grease, and other slippery substances from footwear and platform floor.

1.4OPERATION

General

•Do not use the machine for any purpose other than positioning personnel, their tools, and equipment unless using the optional JLG Material Hook attachment.

•Never operate a machine that is not working properly. If a malfunctions occurs, shut down the machine.

•Never slam a control switch or lever through neutral to an opposite direction. Always return switch to neutral and stop before moving the switch to the next function. Operate controls with slow and even pressure.

•Hydraulic cylinders should never be left fully extended for long periods of time.

•Do not allow personnel to tamper with or operate the machine from the ground with personnel in the platform, except in an emergency.

•Do not carry materials directly on platform railing unless approved by JLG.

SECTION 1 - SAFETY

•Always ensure that power tools are properly stowed and never left hanging by their cord from the platform work area.

•Supplies or tools which extend outside the platform are prohibited unless approved by JLG.

•Do not place boom or platform against any structure to steady the platform or to support the structure.

•Stow boom and shut off all power before leaving machine.

Trip and Fall Hazards

During operation, occupants in the platform must wear a full body harness with a lanyard attached to an authorized lanyard anchorage point. Attach only one (1) lanyard per lanyard anchorage point.

•Before operating the machine, make sure all gates are closed and fastened in their proper position.

•Keep both feet firmly positioned on the platform floor at all times. Do not climb on platform rails. Never use ladders, boxes, steps, planks, or similar items on platform to provide additional reach.

•Never use the boom assembly or the trailer structure to enter or leave the platform.

•Use extreme caution when entering or leaving platform. Be sure that the boom is telescoped out and fully lowered. Face the machine, maintain “three point contact” with the machine, using two hands and one foot or two feet and one hand during entry and exit.

•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 clearance is required for every additional 30,000 volts or less.

•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. This determination shall be made by a qualified person in accordance with the employer, local, or governmental requirements for work practices near energized equipment

SECTION 1 - SAFETY

Tipping Hazards

•The user should be familiar with the surface before operating. Do not exceed the allowable sideslope and grade while operating.

•Do not elevate platform while on a soft surface.

•Before operating on floors, bridges, trucks, and other surfaces, check allowable capacity of the surfaces.

•Never exceed the maximum platform capacity. Distribute loads evenly on platform floor.

•Do not raise the platform unless the machine is on firm surfaces and outriggers are properly set.

•Keep the chassis and outriggers of the machine at least 2 ft. (0.6m) from holes, bumps, drop-offs, obstructions, debris, concealed holes, and other potential hazards on the floor/surface.

•Do not push or pull any object with the boom.

•Never attempt to use the machine as a crane with platform attached. Do not tie-off machine to any adjacent structure.

•Do not operate the machine when wind conditions exceed 28 mph (12.5 m/s).

•Do not increase the surface area of the platform or the load. Increase of the area exposed to the wind will decrease stability and could result in a tip-over.

•Do not increase the platform size with unauthorized platform extensions or attachments.

•If boom assembly or platform is in a position that one or more outriggers are off the ground, all persons must be removed before attempting to stabilize the machine. Use cranes, forklift trucks, or other appropriate equipment to stabilize machine.

SECTION 1 - SAFETY

Crushing and Collision Hazards

•Approved head gear must be worn by all operating and ground personnel.

•Check work area for clearances overhead, on sides, and bottom of platform when lifting or lowering platform, and driving.

•During operation, keep all body parts inside platform railing.

•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, congestion, visibility, slope, location of personnel, and other factors causing hazards of collision or injury to personnel.

•Exercise extreme caution at all times to prevent obstacles from striking or interfering with operating controls and persons in the platform.

•Be sure that operators of other overhead and floor level machines are aware of the aerial work platform’s presence. Disconnect power to overhead cranes.

•Warn personnel not to work, stand, or walk under a raised boom or platform. Position barricades on floor if necessary.
