Operating Instructions
Also read the operating instructions of the equipment this
engine powers.
Pre-Start Checklist
• Check oil level. Add oil if low. Do not overfill.
• Check fuel level. Add fuel if low.
• Check cooling air intake areas and external
surfaces of engine. Make sure they are clean and
unobstructed.
• Check that the air cleaner components and all
shrouds, equipment covers, and guards are in
place and securely fastened.
• Check that any clutches or transmissions are
disengaged or placed in neutral. This is especially
important on equipment with hydrostatic drive.
The shift lever must be exactly in neutral to
prevent resistance which could keep the engine
from starting.
The Emission Compliance Period referred to on the
Emission Control or Air Index label indicates the
number of operating hours for which the engine has
been shown to meet Federal and CARB emission
requirements. The following table provides the Engine
Compliance Period (in hours) associated with the
category descriptor found on the certification label.
