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 sure the ground surface is 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.
Waterlines, 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 riverbed, and the depth and flow
of the water before operating in water or crossing a river.
NEVER work in water that is more than the permissible
water depth.
Any object in vicinity of boom could represent a potential
hazard, or cause the operator to react suddenly and cause
an accident. Use a spotter or signal person when working
near bridges, phone lines, work site scaffolds, or other
obstructions.
