OPERATING INSTRUCTIONS
DANGER
Determine that the trencher is in its original,
factory configuration and has not been modi-
fied or damaged and is not missing parts in any
way. If there are any questions about possible
modifications made to the trencher, do not use
until the modifications have been corrected us-
ing only genuine replacement parts as recom-
mended by Ground Hog or the engine manu-
facturer.
WARNING
Hitting a buried object, such as a rock, could
cause a sudden thrust to the operator. Injury
could occur if the operator is not prepared to
deal with this condition.
STOPPING THE T-4
There are two stop switches on the trencher; one on the
handle bar and one on the engine. Refer to the engine
manual for the switch location on your particular
trencher. The operator can turn the trencher off at any
time by switching either stop switch to the “ OFF “ posi-
tion. Both switches must be “ ON “ before the engine
can start.
STARTING THE T-4
1. Be sure the depth control is in the “ 0 “ depth position
and move both stop switches to the “ON” position.
2. Always stand to the rear of the trencher, away from
the side delivery auger and digging chain while starting
the engine.
3. Start the engine following the procedures outlined in
the engine manual supplied with the trencher.
4. Always start the trencher at the job site and allow it to
warm up. While the machine is running, check that all
controls are working properly before using.
TRENCHING
NOTE: The T-4 trencher is not self propelled.
DANGER
Keep bystanders clear. If the throttle is set
higher than idle when the engine is running,
the digging chain and other components will
move .
