Operating Instructions
5. Turn the key in the ignition switch to ON. The
electric fuel pump will begin operation, forcing
air out around the air bleed screw on the fuel
injection pump. Leave the key in the ON posi-
tion until a solid stream of fuel flows out around
the screw. Tighten the screw and turn the key to
OFF.
Note: Normally the engine should start after the
above bleeding procedures. However, if the
engine does not start, air may be trapped
between the injection pump and the injec-
tors; refer to Bleeding Air From The
Injectors.
AUTOMATIC CLIP CONTROL
The 5300-D is equipped with an electronic controller
which is programmed for automatic clip control.
The machine will automatically adjust the reel speed
to attain the desired clip as the traction speed
changes. For the controller to know what clip is
desired, the operator must input the number of blades
on the reels and the height of cut setting of the
machine.
The range of possible reel speeds is a minimum of
about 600 RPM and a maximum of about 1,800
RPM. As long as the desired clip requires a reel
speed within this range, the machine will maintain
the desired clip. If the traction speed is too slow or
too fast to allow the desired clip, the Reel Control
light (on the front control panel) will illuminate,
indicating that the desired clip is not being main-
tained. For example, if the traction speed is zero, the
reels will still run at the minimum speed of about
600 RPM, which will result in a clip smaller than
desired and cause the Reel Control light to illumi-
nate. The ranges of traction speed that will result in
the desired clip are as follows for several of the pos-
sible heights of cut:
No. of Blades
per C.U.
8

Height of Cut

12 mm (0.50 in.)

2 cm (0.88 in.)
SELECTING CLIP RATE
(REEL SPEED)
To achieve a consistent, high quality of cut, and a
uniform after-cut appearance, it is important that the
reel speed be matched to the height of cut. The
machine controller is programmed to automatically
control the reel speed to give the correct clip, even as
the traction speed changes. To control the reel speed
as desired, the controller must know the height of cut
of the machine, and whether the machine is equipped
with 5- or 8-blade reels.
Adjust the height-of-cut selector knob as follows:
1. Set the 5 / 8 blade switch to the setting indicat-
ing the type of cutting units mounted on the
machine.
2. Verify the height-of-cut settings on the cutting
units. Using the column of the chart listing
either 5- or 8-blade reels, look down the chart to
find the height-of-cut listing nearest the actual
height-of-cut setting. Look across the chart to
find the letter corresponding to that height of
cut.
3. Turn the height-of-cut selector knob to the letter
setting determined in step 2.
4. Operate the machine for several days until the
grass being cut is "conditioned" to being
mowed with this machine. Then examine the
cut to ensure satisfaction with the quality of cut.
The height-of-cut knob may be set one position
on either side of the position shown on the chart
to account for differences in grass condition,
grass length removed, and the personal prefer-
ence of the superintendent.
Full Speed—There may be times when it is desir-
able for the reels to run at full speed, regardless of
the traction speed of the machine. Examples of this
are vertical cutting or heavy scalping. In such cases,
