Introduction
1. INTRODUCTION
This Operator’s Manual has been designed to provide you, the owner, user or operator, with the instructions and
operating procedures essential to properly and safely operate your GMG Aerial Work Platform for positioning
personnel, along with their necessary tools and materials, to overhead work locations.
The Operator’s Manual must be read and understood prior to operating
your GMG Aerial Work Platform. The user/operator should not accept

2.2 FALL PROTECTION
Operators must comply with employer, job site and governmental rules regarding
the use of personal protective equipment.
If required by your employer or job site, use personal fall protection equipment (PFPE)
when operating this machine.
All PFPE must comply with applicable governmental regulations, and must be
Inspected and used in accordance with the PFPE manufacturer’s instructions.
Fall restraint must be properly attached to a designated anchorage point when driving
or operating the machine. Attach only one fall restraint to each anchorage point.
2.3 ELECTROCUTION HAZARD
ELECTROCUTION HAZARD! THIS MACHINE IS NOT INSULATED!
DEATH OR SERIOUS INJURY will result from contact with or inadequate
clearance from any electrically charged conductor.
You must maintain a CLEARANCE OF AT LEAST 3.05 m between any part
of the machine, or its load, and any electrical line or apparatus carrying
over 300 Volts up to 50,000 Volts. 30.5 cm additional clearance is required
for every additional 30,000 Volts.
Observe Minimum Safe Approach Distance.
This machine is not electrically insulated and will not provide protection from contact with
or proximity to electrical current.
Maintain safe distances from electrical power lines and apparatus in accordance with
applicable government regulations and the following chart:
Allow for platform movement, electrical line sway or sag and beware of strong or gusty winds.
Keep away from the machine if it contacts energized power lines. Personnel on the ground or in the platform must not
touch or operate the machine until energized power lines are shut off.
Do not use the machine as a ground for welding.

2.4 TIP-OVER HAZARDS
DO NOT exceed the maximum platform capacity. The weight of options and
accessories will reduce the rated platform capacity and must be factored into the
total platform load. Refer to the decals on the options.
DO NOT elevate the platform when the machine is on a surface that is soft
and / or on a slope.
DO NOT depend on the tilt alarm as a level indicator.
STOP if the tilt alarm sounds and the red light illuminates when the platform is
raised. Use extreme caution to lower the platform. Move the machine to a rm,
level surface.
Driving: DO NOT drive the machine on a slope that exceeds
the maximum uphill or downhill slope rating. Slope rating applies to machines in
the stowed position.
Driving in stowed position: use extreme care and reduce speed when driving
across uneven terrain, debris, unstable or slippery surfaces, and near holes or
drop-offs.
Driving with the platform elevated: DO NOT drive on or near uneven terrain,
unstable surfaces, curbs, drop-offs or other hazardous conditions.
DO NOT push or pull toward any object outside the platform.
DO NOT push the machine or other objects with the platform.
DO NOT contact adjacent structures with the platform.
DO NOT use the platform controls to free a platform that is caught, snagged or
otherwise prevented from normal motion by an adjacent structure. For outdoor
rated machines, DO NOT elevate the platform when wind speeds are in excess
12,5 m/s. If wind speeds exceed 12,5 m/s when the platform is elevated, carefully
lower the platform and discontinue operation.
DO NOT increase the surface area of the platform (i.e. cover the rails with tarp
or plywood). Increased surface area exposed to the wind will decrease machine
stability.
DO NOT attach overhanging loads or use the machine as a crane.
DO NOT place loads outside the platform perimeter.
NEVER transport tools and materials unless they are firmly secured. Secure all
tools and loose materials.
NEVER alter or disable any machine components.
NEVER replace any part of the machine with items of different weight or
specification.
NEVER modify or alter the work platform without written permission from GMG.
NEVER place ladders or scaffolds in the platform or against any part of the
machine.
NEVER use the machine on a moving or mobile surface or vehicle.
Ensure that all tires are in good condition and lug nuts are properly torqued.
DO NOT operate the machine with the chassis trays open.
DO NOT alter or disable the limit switches or machine components that in any
way affect safety and stability.
DO NOT replace items critical to machine stability with items of different weight
or specification. DO NOT modify or alter this machine without prior written
permission from the manufacturer.
DO NOT use batteries that weigh less than the original equipment. Each battery
must weigh 25 kg. The batteries must weigh a minimum of 50 kg.

2.5 FALL HAZARDS
DO NOT sit, stand or climb on the platform guard rails. Maintain a firm footing on the
platform floor at all times.
DO NOT exit the platform when elevated Keep the platform floor clear of debris.
DO NOT fasten a fall restraint lanyard to an adjacent structure.
Ensure that all gates are properly closed and secured before operating the machine.
Operators must comply with employer and job site rules and governmental regulations
regarding the use of personal protective equipment.
Check for equipment, materials or other obstructions before moving.
Check for overhead obstructions before moving.
Check for crushing hazards when holding the platform rail before moving.
Be aware of limited sight distance and blind spots when driving or operating.
Be aware of extended platform position(s) when moving the machine.
Reduce travel speed when moving the machine on slopes, when near personnel and
obstacles, or when surface conditions are wet, slippery or otherwise limiting.
DO NOT operate in the path of any crane unless the controls of the crane have been
locked out and/or precautions have been taken to prevent any possible collision.
Stunt driving and horseplay are PROHIBITED.
Watch for personnel and obstructions below the platform when lowering the platform.
Keep hands and limbs out of scissors.
Use common sense and planning when operating the machine with the controller from
the ground. Maintain safe distances between the operator, the machine and fixed objects.

2.7 ADDITIONAL SAFETY HAZARDS
2.7.1 EXPLOSION AND FIRE HAZARDS
DO NOT operate the machine in hazardous locations or locations where potentially flammable or explosive gases or
particles may be present.
2.7.2 DAMAGED MACHINE HAZARDS
Conduct a thorough prestart inspection of the machine and test all functions before each work shift to check for
damage, malfunction and unauthorized modification. Tag and remove a damaged, malfunctioning or modified
machine from service. DO NOT use a damaged, malfunctioning or modified machine.
Routine maintenance must be performed by the operator before each work shift. Scheduled maintenance must be
performed by a qualified service technician at scheduled intervals. Tag and remove from service any machine that has
not had scheduled preventative maintenance performed.
Check that all safety and instructional decals are in place and undamaged.
Check that the operator’s, safety and responsibilities manuals are present in the storage container located in the
platform. All manuals must be complete, undamaged and readable.
2.7.3 BODILY INJURY HAZARDS
DO NOT operate the machine when there is a hydraulic fluid or air leak. Hydraulic fluid or air under pressure can
penetrate and/or burn skin.
All compartments must remain closed and secure during machine operation. Improper contact with components under
any cover will cause serious injury. Only trained maintenance personnel should access compartments. The operator
should only access a compartment when performing prestart inspection.
2.7.4 WELD LINE TO PLATFORM SAFETY (IF EQUIPPED)
Read, understand and follow all warnings and instructions provided with the welding power unit.
DO NOT connect weld leads or cables unless the welding power unit is turned off at the platform controls.
DO NOT operate unless the weld cables are properly connected.
DO NOT connect the ground lead to the platform.
2.7.5 BATTERY SAFETY
Burn Hazards
Batteries contain acid. Always wear protective clothing and eye wear when working with batteries. Avoid spilling or
contacting battery acid. Neutralize battery acid spills with baking soda and water.
Explosion Hazards
Electrocution Hazards
Avoid contact with electrical terminals.
Keep sparks, flame and lighted tobacco away from batteries. Batteries emit explosive gas. Leave the battery tray
open while charging to avoid gas buildup.
