BEFORE STARTING ENGINE

Work Site Precautions
Before starting operations, thoroughly check the area for any
unusual conditions that could be dangerous.
Check the terrain and condition of the ground at the work site,
and determine the best and safest method of operation.
Make the ground surface as hard and horizontal as possible
before carrying out operations. If there is a lot of dust and sand
on the work site, spray water before starting operations.
If you need to operate on a street, protect pedestrians and cars
by designating a person for work site traffic duty or by erecting
fences and posting "No Entry" signs around the work site.
Erect fences, post "No Entry" signs, and take other steps to
prevent people from coming close to or entering the work site. If
people come close to a moving machine, they may be hit or
caught by the machine, and this may lead to serious personal
injury or death.
Water lines, gas lines, phone lines and high voltage electrical
lines may be buried under the work site. Contact each utility and
identify their locations. Be careful not to damage or cut any of
these lines.
Check the condition of the river bed, and the depth and flow of
the water before operating in water or crossing a river. NEVER
be in water that is in excess of the permissible water depth.
Any type of object in the vicinity of the boom could represent a
potential hazard, or cause the operator to react suddenly and
cause an accident. Use a spotter or signal person working near
bridges, phone lines, work site scaffolds, or other obstructions.
Minimum levels of insurance coverage, work permits or
certification, physical barriers around the work site or restricted
hours of operation may be mandated by governing authorities.
There may also be regulations, guidelines, standards or
restrictions on equipment that may have to be followed for local
requirements. There may also be regulations related to
performing certain kinds of work. If there is any question about
whether your machine and work site complies with the
applicable standards and regulations contact your local
authorities and agencies.
Avoid entering soft ground. It will be difficult for the machine to
escape.
Avoid operating your machine to close to the edge of cliffs,
overhangs, and deep ditches. The ground may be weak in such
