WARNING
An illuminated warning light could indicate a
serious problem that could lead to personal
injury.
When the engine is operating all warning
lights should be off. If a warning light
illuminates, shut off the engine immediately
and have the fault rectified before starting the
engine.
Starting a Warm Engine
1.
Sit on the seat, keep your foot off the traction
pedal so that it is in Neutral, engage the parking
brake, and set the throttle to the 70 percent full
throttle.
2.
Turn the ignition key to the ignition on position
I and check that the engine oil pressure and
battery charge warning lights illuminate.
3.
Turn the ignition key to the start position III and
hold to crank the engine.
4.
Crank the engine for no longer than 15 seconds.
Release the ignition key back to position I when
the engine starts.
5.
Run the engine at low idle speed until it warms
up.
Shutting off the Engine
1.
Move all controls to neutral, engage the parking
brake, move the throttle to the low idle position,
and allow the engine to reach low idle speed.
Important:
Allow the engine to idle for 5
minutes before shutting it off after a full
load operation. Failure to do so may lead to
trouble on a turbo-charged engine.
2.
Let the engine idle for 5 minutes.
3.
Turn the ignition key to position 0.
If the engine fails to shut off when the ignition
key is turned to 0, operate the engine shutoff
lever in the forward direction

WARNING
Contact with hot or moving parts can
result in personal injury.
Keep all body parts away from any hot or
moving parts of the engine.

Adjusting the Center
Cutting Unit Height-of-Cut
Correction
With all cutting units set at the same HOC via the
indicator rings, you may notice that the center unit
produces a higher cut finish compared to the wing
units. The center unit is pulled and the wing units
are pushed; this presents marginally different cutting
angles relative to the ground. The amount of HOC
variation which results from this is influenced by the
terrain, but you can achieve satisfactory results by
setting the center cutting unit HOC indicator ring lower
than the wing unit settings.
Controlling the Position of
the Individual Cutting Units
You can raise or lower the cutting units independently
using the bank of 3 lift control switches.
1.
To lower the cutting units, operate the lift control
switches in a downward direction and release.
Note:
The cutting unit drive switch must be on
(forward) to do this. The reel drive engages
when the cutting units are approximately 150
mm (6 inches) above ground level. The cutting
units are now in float mode and will follow the
ground contours.
