Pump the lever on the fuel pump (Fig. 12) until
a solid stream of fuel flows out around the
screw on the fuel injection pump. Tighten the
air bleed screw.
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 injectors;
refer to Bleeding Air From The Injectors.
Setting 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.
Adjust the reel speed controls as follows:
1.
Select the height-of-cut at which the cutting
units should be set.
2.
Choose the desired ground speed best suited
for conditions.
3.
Using the appropriate graph (Fig. 15) for 5-, 7-
or 11-blade cutting units, determine the correct
reel speed setting.
4.
To set reel speed, rotate knobs (Fig. 25) until
indicator arrows are in line with the number
designating desired setting.
