INITIAL RUN-IN PROCEDURES
(FIRST DAY OF USE OR APPROXI-
MATELY 10 HOURS)
1. Check the belts for proper tension at 2, 4 and 8
hours. Adjust as needed.
2. Check the steering control rods for neutral
adjustment. (See Adjustments, page 6)
3. Checkthetiresforproperpressure.

before attempting to operate this machine.
2. Before starting the engine:
* Check the oil level in the engine.
* Fillthefueltankwithclean,fresh,lead-free
gasoline.
*Openthefuelvalveonthebottomofthefuel

MOWER OPERATION
-NOTE-
Use gasoline with an octane rating no less than
87.
* The transmission must be in NEUTRAL.
* The blade clutch switch must be in the OFF
position.
* The operator's presence levers must be
released.
* The neutral latches must be in the neutral
lock position.
* The key switch must be on.
3. Start the engine:
* Choke as required. If the engine is cold, pull
the choke knob out. When the engine starts,
slowly push the choke in. If the engine stalls,
repeat the above operation. When the engine
is warm, choking may not be necessary.

-NOTE-
When PTO is engaged or (possibly) disengaged,
a squealing sound from the underside of the
machine is normal. It is caused by the electric
clutch plates meshing as the cutter blades come
up to speed. For best equipment life, engage the
clutch with the engine at 3/4 throttle, not under
full load.

B. 3-1/2" Position (factory setting) - baffle is installed
using the bottom set of holes on the Custom Cut
Baffle. (See Figure 11). For general purpose
cutting, place the Custom Cut Baffle in the 3-1/2"
position. This gives the best mix of cutting
performance in all types of grass.
A. 3" Position - baffle removed. (See Figure 10). With
the baffle removed, the Advantage cutter deck will
deliver the best quality-of-cut in very tall, wiry, tough
to cut grass.
The Custom-Cut Baffle is designed to deliver optimum
airflow and superior cutting performance in any type of
grass. The Custom-Cut Baffle can be raised or lowered
to precisely tailor the deck's performance for the type of
grass being cut. The baffle can be set in three (3)
different positions for optimum performance.
