Checking the PT O Safety-Interlock
System
Service Interval : Before each use or daily
Before doing the following checks, perform the
following:
1. Sit in the operator ’ s seat.
2. Engage the parking brake.
3. Move the traction pedal to neutral.
4. Disengage the PT O.
5. Start the engine.
6. Disengage the parking brake.
Check the operation of the safety-interlock switches
by ensuring the following:

Adding Fuel
Use only clean, fresh diesel fuel or biodiesel fuels with
low (<500 ppm) or ultra low (<15 ppm) sulfur content.
The minimum cetane rating should be 40. Purchase
fuel in quantities that can be used within 180 days
to ensure fuel freshness.
Fuel tank capacity: 22 L (5.8 US gallons)
Use summer-grade diesel fuel (No. 2-D) at
temperatures above -7°C (20°F) and winter-grade
(No. 1-D or No. 1-D/2-D blend) below that
temperature. Using winter-grade fuel at lower
temperatures provides lower ash point and cold ow
characteristics which will ease starting and reduce
fuel lter plugging.
Using summer-grade fuel above -7°C (20°F) will
contribute toward longer fuel pump life and increased
power compared to winter-grade fuel.
Important: Do not use kerosene or gasoline
instead of diesel fuel. Failure to observe this
caution will damage the engine.
Biodiesel Ready
This machine can also use a biodiesel blended fuel
of up to B20 (20% biodiesel, 80% petrodiesel). The
petrodiesel portion should be low or ultra low sulfur .
Observe the following precautions:
• The biodiesel portion of the fuel must meet
specication ASTM D6751 or EN14214.
• The blended fuel composition should meet ASTM
D975 or EN590.
• If you spill biodiesel fuel blends, the fuel may
damage painted surfaces.
• Use B5 (biodiesel content of 5%) or lesser blends
in cold weather .
• Monitor the seals, hoses, and gaskets in contact
with fuel as they may degrade over time.
• Expect fuel lter plugging for a time after converting
to biodiesel blends.
• Contact your authorized T oro distributor if you
want more information on biodiesel.
