Operation

Warning
ROTATING PARTS CAN CAUSE SERIOUS
PERSONAL INJURY
• Keep hands and feet away from sweeper reels
while machine is running.
• Keep hands, feet, hair, and clothing away from
all moving parts to prevent injury.
• NEVER operate the machine with covers,
shrouds, or guards removed.
1. Place the unit on a level surface and apply the parking
brake.
2. Remove foot from traction pedal and make sure pedal is
in neutral position.
3. With the throttle 1/2 open and the choke closed, insert
key into ignition switch and rotate it clockwise to start
engine. Release key when engine starts and open the
choke gradually.
Note: Do not run starter motor more than 10 seconds at a
time or premature starter failure may result. If engine fails
to start after 10 seconds, turn key to OFF position, recheck
controls and procedure. wait 60 seconds and repeat starter
operation.
4. When engine is started for the first time, after engine oil
change, hydraulic oil change or hydraulic service work,
operate the machine in forward and reverse for one to
two minutes. Also operate the Reel PTO Engagement
and Hopper Door Release to verity proper operation of
all parts.
5. Turn steering wheel to the left and right to check
steering response. Shut off engine and check fluid
levels. Check for oil leaks, loose parts and any
noticeable malfunctions.

Checking Interlock System

The purpose of the safety interlock system is to prevent the
engine from cranking or starting unless the traction pedal is
in neutral and the Reel PTO Engagement handle is in the
OFF (disengaged) position. In addition, the engine will stop
when the Reel PTO is engaged or the traction pedal is
depressed with the operator off the seat. Indications of a
disconnected or malfunctioning interlock switch are:
A. A disconnected or malfunctioning safety interlock
switch could allow the engine to be started when the
traction pedal is not in the neutral position or the
Reel PTO Engagement handle is in the HIGH or
LOW (engaged) position.
B. A disconnected or malfunctioning safety interlock
switch could allow the engine to continue running
when the Reel PTO Engagement handle is in the
HIGH or LOW (engaged) position or the traction
pedal is depressed with the operator off the seat.
Caution
SAFETY INTERLOCK SWITCHES ARE FOR
THE OPERATOR'S PROTECTION.
DISCONNECTED OR MALFUNCTIONING
SAFETY INTERLOCK SWITCHES COULD
ALLOW THE MACHINE TO OPERATE IN AN
UNSAFE MANNER AND MAY CAUSE
PERSONAL INJURY.
• Do not disconnect the safety interlock switches.
• Check operation of the switches daily to be sure
the interlock system is operating correctly.
• If a switch is malfunctioning, replace it before
operating the machine.
• Replace switches every 2 years to be sure of
maximum safety.
1. Sit on operator's seat and engage parking brake.
2. Move the Reel PTO Engagement handle to the OFF
position and remove foot from traction pedal (neutral
position).
3. Rotate the ignition key to START. Engine should crank.
If engine cranks, proceed to step 4. If engine fails to
crank, there may be a malfunction in the interlock
system.
4. Raise off the seat and position the Reel PTO
engagement handle to either the HIGH or LOW
position while the engine is running. The engine should
stop within 2 seconds. If the engine stops, the switch is
operating correctly; proceed to step 5. If the engine does
not stop, there is a malfunction in the interlock system.
5. Raise off the seat and depress the traction pedal while
the engine is running and the Reel PTO is disengaged.
The engine should stop within 2 seconds. If the engine
stops, the switch is operating correctly; continue
operation. If the engine does not stop, there is a
malfunction in the interlock system.

Operating Characteristics

Practice driving the TURF SWEEPER 4800 before initial
operation because the hydrostatic transmission and its
characteristics are different than some turf maintenance
machines. Some points to consider when operating the
sweeper are the engine speed, transmission speed, and the
load on the sweeper reels.
