INFORMATION CONTAINED
IN THIS MANUAL.
At Tesco, we put a lot of effortinto developing ways to make

Training the operators to run
the equipment in the most

easier by reducing downtime

risk of injury to workers.
This manual will provide you
with information to present
to your crew during a pre-job
safety meeting or whenever
you need toreinforce what you already know.
