Testing The Safety Interlock System; Safe Handling Of Gasoline - Scag Power Equipment SZL-36H-18FR Operator's Manual

Section 2
16. Make sure all hydraulic fluid connections are tight
and all hydraulic hoses and lines are in good
condition before starting the machine.
WARNING
This machine is equipped with an interlock system
intended to protect the operator and others from
injury. This is accomplished by preventing the
engine from starting unless the deck drive is
disengaged, the steering control levers are in the
neutral position and the operator is in the seat.
The system shuts off the engine if the operator
leaves the seat with the deck drive engaged and/
or the steering control levers are not in the neutral
position and the parking brake is not engaged.
Never operate equipment with the interlock
system disconnected or malfunctioning.
17. Test the operation of the safety interlock system. See
Section 4.2, Page 13.
18. Be sure the interlock switches are functioning
correctly.
2.6 TESTING THE SAFETY INTERLOCK
SYSTEM
The safety interlock system should be tested each time
before using the machine. If the safety interlock system
does not operate as described below, contact your local
Authorized Scag Power Equipment Dealer immediately to
have the safety interlock system repaired.
1. Sit in the seat in the operating position, engage the
parking brake, place the steering control levers in
the neutral lock position, and engage the PTO switch
to the ON (up) position. Try to start the engine; the
engine should not start
2. Sit in the seat in the operating position, engage the
parking brake, move the PTO switch to the OFF
(down) position, move either of the steering control
handles out of the neutral lock position. Try to start
the engine; the engine should not start. Repeat for
the other steering control lever.
All SZL models will start with the parking brake
engaged or disengaged. For all test procedures
listed below, the engine should be started with the
parking brake engaged unless specified otherwise.
3. Sit in the seat in the operating position, engage the
parking brake, place the steering control levers in
the neutral lock position, move the PTO switch to the
OFF (down) position, and start the engine. With the
engine running, release the parking brake and rise
slightly off of the seat. The engine should shut off.
4. Sit in the seat in the operating position, engage the
parking brake, place the steering control levers in
the neutral lock position, move the PTO switch to the
OFF (down) position, and start the engine. With the
engine running, engage the PTO switch to the ON
(up) position, and rise slightly off of the seat. The
engine should shut off.
5. Sit in the seat in the operating position, engage the
parking brake, place the steering control levers in
the neutral lock position, move the PTO switch to the
OFF (down) position, and start the engine. With the
engine running, move either steering control lever
out of the neutral lock position. The engine should
shut off. Repeat for the other steering control lever.

2.7 SAFE HANDLING OF GASOLINE

To avoid personal injury or property damage, use extreme
care in handling gasoline. Gasoline is extremely flammable
and the vapors are explosive.
1. See Section 7.5 ENGINE FUEL SYSTEM for fueling
procedure.
2. Fuel is flammable; handle it with care. Clean up any
spilled fuel immediately. If fuel spills on clothing,
change clothing immediately. If fuel is spilled near
the machine, DO NOT attempt to start the engine but
move the machine away from the area of spillage.
Avoid creating any source of ignition until fuel vapors
have dissipated.
3. Prevent fire and explosion caused by static electric
discharge. Static electric discharge can ignite fuel
vapors in an ungrounded fuel container.
4. Never store the machine or fuel container where
there is an open flame, spark, or pilot light such as a
water heater or other appliances.
5. Extinguish all cigarettes, cigars, pipes, and other
sources of ignition.
