Checking The Engine-Oil Level; Breaking In A New Machine - Toro 74997 Operator's Manual

Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
•
Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank
be drained.
•
Cleans the engine while it runs
•
Eliminates gum-like varnish buildup in the fuel system,
which causes hard starting
Important: Do not use fuel additives containing
methanol or ethanol.
Add the correct amount of gasoline stabilizer/conditioner
to the gasoline.
Note: A fuel stabilizer/conditioner is most effective
when mixed with fresh gasoline. To minimize the
chance of varnish deposits in the fuel system, use fuel
stabilizer/conditioner at all times.
Filling the Fuel Tank
Note: Do not fill the fuel tank completely full. Fill the fuel
tank to the bottom of the filler neck. The empty space in the
tank allows the gasoline to expand.
1. Park the machine on level ground.
2. Shut the engine off and set the parking brake.
3. Clean around the fuel-tank cap and remove the cap.
4. Fill the fuel tank to the bottom of the filler neck

Note: Ensure that there is empty space in the tank to
allow the gasoline to expand.

Before you start the engine and use the machine, check
the oil level in the engine crankcase; refer to

Breaking in a New Machine

New engines take time to develop full power. Mower decks
and drive systems have higher friction when new, placing
additional load on the engine. Allow 40 to 50 hours of
break-in time for new machines to develop full power and
best performance.
