SAFETY SYMBOLS
This section of the manual contains important information of the safe use of your MEC
Scissors. Failure to read, understand, and follow all safety rules, warnings, and instructions
will unnecessarily expose you and others to dangerous situations. For your safety and the
safety of those around you, you must operate your machine as instructed in this manual.
You, the operator, are the single most important factor for safety when using any piece of
equipment. Learn to operate your machine in a safe manner.
To help you recognize important safety information, we have identified warnings and in-
structions that directly impact on safety with the following signals:
“DANGER” INDICATES AN IMMINENTLY HAZARDOUS
SITUATION WHICH, IF NOT AVOIDED, WILL RESULT IN DEATH
OR SERIOUS INJURY. THIS SIGNAL WORD IS LIMITED TO THE
MOST EXTREME SITUATIONS.
“WARNING” INDICATES A POTENTIALLY HAZARDOUS
SITUATION WHICH, IF NOT AVOIDED, COULD RESULT IN
DEATH OR SERIOUS INJURY.
“CAUTION” indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury. It may also be used
to alert against unsafe practices. “CAUTION” is used for property-
damage only accidents.

SAFETY RULES AND PRECAUTIONS
♦MEC designs self-propelled scissor lifts to be safe and reliable. They are in-
tended to position personnel, along with their necessary tools and materials to
overhead work locations.
♦The owner/user/operator of the machine should not accept responsibility for the
operation of the machine, unless properly trained.
♦ANSI A92.6 and other applicable standards identify requirements of all parties
who may be involved with self-propelled elevating work platforms. The A92.6
Manual of Responsibilities is considered a part of this machine and can be found
in the manual compartment, located at the platform control station.
♦To insure safe use of machine, inspections specified in Section 6.7 of
ANSI A92.6-1999 must be performed at designated intervals as prescribed by
ANSI A92.6-1999.
♦♦
♦♦
♦ELECTROCUTION HAZARD!!! THIS MACHINE IS NOT INSULATED!!
♦Maintain safe clearance from electrically charged conductors (power lines) and
apparatus. You must allow for machine sway (side to side movement) when
elevated and electrical line movement. This machine does not provide protection
from contact with, or proximity to, an electrically charged conductor.
♦You must maintain a CLEARANCE OF AT LEAST 10 FEET (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. One foot (30.5 cm) additional clearance is
required for every additional 30,000 volts.
♦DEATH OR SERIOUS INJURY will result from contact with or inadequate clear-
ance from any electrically charged conductor.
♦Only authorized, trained and qualified personnel should operate the scissor lift.
♦NEVER fasten fall protection lanyard to an adjacent structure while on the plat-
form.
♦Make sure that the platform entry is properly closed and secure before operating
machine from the platform.
♦NEVER exceed platform rated capacity. Review the section titled “Machine
Specifications” (earlier in this manual) regarding model capacities and dimen-
sions.

♦Before operating the machine, read and understand all safety and control informa-
tion found on the machine and in this manual.
♦When operating the machine follow all safety and control information found on the
machine and in this manual.
♦Evenly distribute loads placed on the platform.
♦NEVER use scaffolding, ladders or similar items to extend your reach while on the
platform.
♦NEVER climb down the beam assembly while the platform is raised.
♦The “Moving the Machine” section (described later in this manual) requires that the
brake be released. After performing this procedure, there is no means to stop the
machine’s travel. MEC recommends using this procedure only in cases of emer-
gency, and only for a short distance. Be on guard against machine runaway on
sloping surfaces. Movement speed shall not exceed 5 MPH (8.0 kph).
♦NEVER attempt to open any hydraulic line or component without first relieving all
system pressure.
♦NEVER alter, modify, or disable any safety devices or interlocks.
♦NEVER recharge the battery near sparks or open flames. Lead-acid batteries gener-
ate EXPLOSIVE HYDROGEN GAS. Always wear safety glasses.
♦NEVER use the machine outdoors during electrical storms or in high wind situations.
♦Only raise the platform when the machine is on a firm, level surface.
♦SECURE all tools and other loose items to prevent injury to persons working on or
below the platform.
♦Precautions should be taken to prevent unauthorized personnel from operating the
platform with the ground controls while the platform is in use.
♦Before disengaging or disconnecting hydraulic motors with brake assembly from a
towing vehicle, ensure that the machine cannot roll.
♦Complete the “Operational Checklist” at designated intervals.
