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
areas. If the ground should collapse, the machine could fall or tip
over and this could result in serious injury or death.
Remember that the soil after heavy rain, blasting or after
earthquakes, is weakened in these areas.
Earth laid on the ground and the soil near ditches is loose. It can
collapse under the weight of vibration of your machine and
cause your machine to tip over.
Install the head guard (FOPS) if working in areas where there is
danger of falling rocks.
