CONGRATULATIONS
The Ranger Tug family has a passion for boating. We are committed to continuous
process improvement in all areas that affect our customer’s satisfaction with our
products and providing great customer service.
SAFETY
Safety is always a concern at Ranger Tugs. Please read all manuals to ensure that
equipment is used in a safe manner. We highly recommend attendance in a Coast
Guard approved boating safety course. Such courses are available from the Coast
Guard directly or from boating organizations. Owners should have annual inspec-
tions to ensure that all safety equipment is current.
Operating, servicing and maintaining
a recreational marine vessel can expose
you to chemicals including engine exhaust,
carbon monoxide, phthalates, and lead,
which are known to the State of California
to cause cancer and birth defects or other
reproductive harm. To minimize exposure,
avoid breathing exhaust, service your vessel
in a well-ventilated area and wear gloves or
wash your hands frequently when servicing
this vessel. For more information go to
www.P65warnings.ca.gov/marine.
