Toro Greensmaster 3120, Operator'S Manual, Page: 20 / 48

Breaking in the Machine
Refer to the engine manual supplied with the
machine for oil change and maintenance procedures
recommended during the break-in period.
Only 8 hours of operation is required for the break-in
period.
Since the first hours of operation are critical to future
dependability of the machine, monitor its functions and
performance closely so that minor difficulties, which
could lead to major problems, are noted and can be
corrected. Inspect the machine frequently during
break-in for signs of oil leakage, loose fasteners, or
any other malfunction.
Starting the Engine
Inspect the area beneath the cutting units to ensure
that they are clear of debris.
1. Sit on the seat, engage the parking brake,
disengage the raise/lower mow control and
move the functional-control lever to the N
EUTRAL
position.
2. Ensure that the traction pedal is in the N
EUTRAL
position and that your foot is off the pedal.
3. If you are starting a cold engine, move the choke
to the O
N
position.
4. Move the throttle lever to the H
ALF
T
HROTTLE
position.
5. Insert and rotate the ignition key clockwise until
the engine starts.
6. After the engine starts, adjust the choke to run
the engine smoothly. As soon as possible, open
the choke by pulling it rearward to the O
FF
position. A warm engine requires little or no
choking.
Checking the Machine After
Starting the Engine
1. Move the throttle lever to the F
AST
position.
2. Move the raise/lower mow control lever forward
momentarily.
The cutting units should lower and all the reels
should rotate.
Note:
The function lever should be in the
middle (mow) position for the reels to run when
lowering the cutting units
3. Move the raise/lower mow control lever
rearward.
The cutting reels should stop rotating and the
cutting units should raise to the full transport
position.
4. Engage the brake to keep the machine from
moving, and shut off the engine.
5. Check the lip of each basket to ensure the lip is
not in contact with the reel during step
2 .
If you see signs of contact, adjust the pull arms;
refer to
4 Installing the Cutting Units (page 11) .
6. Check for the machine for hydraulic-fluid leaks
and tighten the hydraulic fittings if any are found.
Note:
When the machine is new and the
bearings and reels are tight, it is necessary to
set the throttle lever to the F
AST
position for this
check. A fast throttle setting may not be required
after the break-in period.
Note:
If fluid leaks continue to appear, contact
your Authorized Toro Distributor for assistance
and, if necessary, replacement parts.
Important:
A trace of fluid on the motor or
wheel seals is normal. Seals require a small
amount of lubrication to perform properly.
Shutting Off the Engine
1. Move the throttle lever to the S
LOW
position, pull
back the raise/lower mow control, and move the
functional-control lever to the N
EUTRAL
position.
2. Rotate the ignition key to the O
FF
position to
shut off the engine. Remove the key from the
switch to prevent accidental starting.
3. Close the fuel-shutoff valve before storing the
machine.
Checking the
Safety-Interlock System
Service Interval: Before each use or daily
CAUTION
If the safety interlock switches are
disconnected or damaged the machine could
operate unexpectedly, causing personal
injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock
switches daily and replace any damaged
switches before operating the machine.
The purpose of the safety-interlock system is to
prevent operation of the machine where there is
possible injury to you or damage to the machine.
