Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
•
The blades are disengaged.
•
The motion control levers are in the brake position.
The safety interlock system also is designed to stop the
engine when the control levers are out of the brake
position and you rise from the seat when the blades
are engaged.
Testing the Safety Interlock System
Service Interval:
Before each use or daily
Test the safety interlock system before you use the
machine each time. If the safety system does not
operate as described below, have an Authorized Service
Dealer repair the safety system immediately.
1. While sitting on the seat, with the control levers in
brake position, and move the blade control switch
to On. Try starting the engine; the engine should
not crank.
2. While sitting on the seat, move the blade control
switch to Off. Move either motion control lever
to the center, unlocked position. Try starting the
engine; the engine should not crank. Repeat with
the other motion control lever.
3. While sitting on the seat, move the blade control
switch to Off, and lock the motion control levers
in neutral. Start the engine. While the engine is
running, move the motion control levers to the
center, unlocked position, engage the blade control
switch, and rise slightly from the seat; the engine
should stop.
4. Remove the collection bag. While sitting on the
seat, start the engine and move the blade control
switch to On. The blades should not engage.
Adjusting the Height of Cut
The height of cut is adjusted from 1-1/2 to 4-1/2 inch
(38 to 114 mm) in 1/2 inch (13 mm) increments by
moving the height-of-cut lever in different locations.
1. Raise the height-of-cut lever to the transport
position (also the 4-1/2 inch (114 mm) cutting
height position (Figure 15).
2. To adjust, pull up on the height-of-cut lever and
move it to the desired position (Figure 15).
