SAFETY

MHP Operating & Maintenance Manual 5
• If the attachment is not functioning properly, shut
down the machine, follow proper lockout / tag out
procedures and follow proper repair procedures.
• NEVER operate equipment without the original
safety guards in place.
• Ensure that the cab is equipped with the proper
safety guards for LaBounty applications. The
cab MUST be equipped with an approved Falling
Object Protection Structure (FOPS). The FOPS
must meet the requirements of SAE standard
J1356. A transparent, shatter-resistant shield
covering the front of the cab, is also required.
Contact your base machine equipment dealer
or manufacturer for more information on the
availability of FOPS. Lack of proper FOPS may
result in injury or death.
• NEVER operate the excavator without a proper
restraint (seat belt) system in place. Doing so can
create loss of control or ejection from cab.
• NEVER operate the equipment while under the
inuence of drugs, alcohol or other substances
that inhibit mental abilities or reaction time.
• DO NOT process material with the attachment
over the operator’s cab. Doing so will result in
severe personal injury or death from falling debris.
• DO NOT attempt to process brittle materials, such
as axles and railroad rail. DO NOT process any
material in a position that may propel it toward the
operator, other workers, buildings or equipment.
• Clear all persons and equipment from the area of
operation and machine movement. NEVER move
loads over people or equipment. When viewing
the operation of the attachment, maintain a safe
distance of at least 75 feet (23 meters).
• NEVER approach power lines with any part of the
machine. Keep clear at a minimum of 15 feet (5
meters).
• DO NOT close the attachment on a structure and
reverse the excavator in an attempt to pull down
material.
• Avoid tipping. The attachment will alter the
lift capacities of the base machine. DO NOT
overload the excavator or serious injury could
result. Lift capacities will vary if the base machine
is not on level ground. Lifting incorrectly can
cause severe injury or machine damage. Use
the recommended excavator counterweight.
Use short slings and lift the load only as high as
necessary.
• Use of this tool on certain materials could
generate dust potentially containing a variety
of hazardous substances, such as, asbestos,
silica or lead. Inhalation of dust containing
these, or other hazardous substances could
result in serious injury, cancer or death. Protect
yourself and those around you. Research and
understand the materials you are processing.
Follow safety procedures and comply with all
applicable national, state or provisional health and
safety regulations relating to them. If appropriate,
arrange for the safe disposal of the materials by a
qualied person.
• Disassembly of any pin-connected attachment
can be hazardous. NEVER remove any pin unless
the attachment is on the ground and blocked
up. Serious injury or death could result. Metal
chips or debris may y when a connecting pin is
struck. Use a brass drift when striking pins and
always wear protective clothing and proper eye
protection. Pins may y when struck with force
to drive them in or out. Always keep people clear
when removing or installing pins.
• DO NOT allow riders on the machine. Riders are
subject to serious injuries, such as being struck
by foreign objects or being thrown off the machine.
Riders also distract and obstruct the operator,
resulting in the machine being operated in an
