SAFETY INSTRUCTIONS OVERVIEW
READ SAFETY AND OPERATING INSTRUCTIONS BEFORE OPERATING!
USE COMMON SENSE AND PLENTY OF IT!
Call before you dig. If you do not call, you may cause an accident; suffer injuries or death; cause
interruption of services; damage the environment; and/or incur project delays. Expect to be held
liable for any damages caused, if you fail to call.
DANGER: Buried electric cables or gas lines can cause serious injury or death if struck with
dig chain. Always determine location of utilities before trenching.
WARNING: Fiber optic cables convey laser light that can injure your eyesight.
STAY CLEAR of moving parts on the trencher.
DANGER: Digging chain, auger and other moving parts can cut off
arms, legs, or fingers. Contact with the digging chain or auger while
in operation will cause serious injury or even death.
Wear safety goggles and a hard hat while operating or observing!
WARNING: The dig chain may throw stones and debris.
Wear adequate hearing protection while operating or observing.
WARNING: Exposure to loud noise is cumulative and may
permanently damage your hearing.
Wear safety boots and gloves. Wear close-fitting clothing. Contain
long hair. Do not wear jewelry. Wear reflective clothing if working
near traffic.
Only operate outdoors and avoid breathing engine exhaust and fumes.
WARNING: Engine exhaust contains carbon monoxide gas that is toxic. Breathing it can
cause unconsciousness and death.
Adequate lighting is required, daylight or artificial, for safe operation of the trencher.
Allow adequate side and overhead clearances between trencher and buildings, fences, and trees.
WARNING: If the dig chain contacts an object the digging chain can climb upward quickly
and tip the trencher toward the operator. Serious injury or death will result by operator contact
with the moving chain. The digging chain can suddenly drag the machine forward if the trencher is
forced too quickly into the ground or catches on a buried object.
