No modifications. Never modify or alter the engine in
any way. Modifications can create serious safety
hazards and will also void the warranty.
Improper maintenance or failure to perform pre-
operation checks before operation will result in
malfunctions that could cause serious injury to you or
others.
Follow Safety Rules
Read and follow these safety rules whenever you
will be servicing the engine:
Turn off.
Always turn off before inspection or
•
maintenance. Remove spark plug or spark plug wire
to prevent accidental starting.
Replace guards. Make sure all guards and cover
•
shields are replaced after servicing.
•
Major repair. Major service, including the installation
or replacement of parts, should be performed only by a
qualified service technician. Obtain factory approved
parts from NorthStar Product Support at 1-800-270-
0810.
Replacement parts. If a part needs replacement, only
•
use factory approved repair parts. Replacement parts
that do not meet specifications may result in a safety
hazard or poor operation of the engine and will void the
warranty.
Keep Engine Clean
If dust or debris accumulates on the engine, clean with a
damp cloth or soft bristle brush. Do not allow air intakes
to become blocked.
Carbon Monoxide Hazard
Exhaust fumes from the engine contain carbon monoxide
(CO), a poisonous gas you cannot see, smell, or taste. The CO
generated by the engine can rapidly accumulate, even in areas
that appear to be well ventilated, resulting in dangerous and fatal
concentrations within minutes. NEVER run engine inside any
enclosed or semi-enclosed spaces, including homes, garages,
basements, sheds, boxes, pick-up truck beds, RVs, or boats.
These spaces can trap poisonous gases, EVEN if you run a fan
or open windows. If you start to feel sick, dizzy, or weak while
using the engine, shut off the engine and get to fresh air RIGHT
AWAY. See a doctor. You may have carbon monoxide poisoning.
