SAFETY INSTRUCTIONS OVERVIEW (continued)
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 digging 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.
WARNING
: Contact with the dig chain or auger while in operation will cause serious injury or even death. The
teeth of the dig chain are sharp. Avoid contact even when the chain is not moving.
Avoid inclines if at all possible.
WARNING
: Navigating on any incline increases the danger of the trencher losing traction or rolling over,
especially if the surface is wet. If you lose control, get out of the way immediately to avoid personal injury.
Navigation on inclines should be especially slow and turns very gradual. Refer to the incline diagram in the
section, “GROUND TRANSPORT”.
WARNING
: The weight of the trencher or walking near the edge of the trench could cause collapse of the
trench wall. If driven along the edge of the trench, the trencher could suddenly turn over.
Avoid operating adjacent to drop-offs or embankments.
WARNING
: The trencher is very heavy.
DO NOT
attempt to manually lift it.
Keep away from wheels to avoid getting crushed.
WARNING
: Getting run over by the trencher will cause injury.
Always leave trencher parked on a level surface.
WARNING
: Do not park on incline. Move the trencher to a level area.
Do not leave trencher unattended with the engine running.
