SAFETY INSTRUCTIONS
This safety alert symbol
means CAUTION, WARN-
ING or DANGER — "per-
sonal safety instruction”.
Read and understand the
instruction because it has
to do with safety. Failure
to comply with the instruction may result
in personal injury.
The following instructions are comparable to the
Instructions for Safe Snowthrowing adopted by
ANSI — American National Standards Institute
В71.3 - 1975.
The 48” Snowthrower is designed and tested to
offer reasonably safe service. Failure to operate
the machine in accordance with these Safety
Instructions MAY RESULT IN PERSONAL
INJURY.
BEFORE OPERATING
1. Read and understand the contents of these
Installation Instructions and the Operator's
Manual and the Operator's and Service Manual for
the Groundsmaintenance Tractor before starting
and operating the machine. Become familiar with
all controls and know how to stop quickly. A
replacement manual is available by sending
complete Model and Serial Number to:
The Toro Company
8111 Lyndale Avenue South
Minneapolis, Minnesota 55420
2. 425 pounds (193 kg) ballast must be installed
into the rear box of the traction unit as forward
stability and steering control will be seriously
degraded when the snowthrower is in the raised
position during operation,
3. Never allow children or adults unfamiliar with
its operation to operate the machine, and keep
everyone, especially children and pets, away from
the area of operation.
4. Keep all shields and safety devices in place. If
a shield, safety device or decal is defective or
damaged, repair or replace it before operation 15
commenced. Also tighten any loose nuts, bolts and
screws to make sure machine is in safe operating
condition.
5. Do not wear loose fitting clothing which could
get caught in moving parts. Wearing safety glasses,
safety shoes and a helmet is advisable and required
by some local ordinances and insurance regulations.
6. Be sure interlock switches are adjusted correctly
so engine cannot be started unless traction speed
control lever isin neutral position — and implement
clutch lever is in DISENGAGE position.
7. Fill fuel tank with gasoline before starting the
engine. Avoid spilling any gasoline. Since gasoline
is highly flammable, handle it carefully — DO NOT
SMOKE.
A. Use an approved gasoline container.
B. Fill fuel tank outdoors and only when
engine is not running. Engine must be cool
to prevent a potential fire hazard.
C. Wipe up any gasoline that spilled, and in-
stall gasoline container cap and machine
fuel tank cap securely before starting the
engine,
WHILE OPERATING
8. Do not operate without first installing 425
pounds (193 kg) ballast to the rear box of the
traction unit. Forward stability and steering
control will be seriously degraded without the
weight installed.
9. Do not run the engine in a confined area
without adequate ventilation. Exhaust fumes are
hazardous and could possibly be deadly.
10. Maximum seating capacity is one person. Never
carry passengers.
11. Sit on the seat when starting the engine and
operating the machine.
12. When starting the engine:
A. Engage park lock.
B. Make sure traction speed control lever is in
neutral and implement clutch lever is in
disengage position.
C. After engine is started, release park lock
and keep hand off traction speed control
lever. Machine must not move. |f movement
is evident, the neutral return mechanism is
adjusted incorrectly; therefore, shut engine
off and adjust until machine does not move
when traction speed control lever is in
neutral position.
13. Using the machine demands attention, and to
prevent loss of control:

ing roads. Always yield the right-of-way.
14. Never direct discharge of snow or operate
snowthrower near bystanders, glass enclosures,
automobiles and trucks, window wells or a drop-
off without proper adjustment of the snow dis-
charge angle.
15. If the snowthrower strikes a solid object or
the machine vibrates abnormally, disengage imple-
ment clutch lever, return traction speed control
to neutral, move throttle to slow, set park lock
and shut engine off, Remove key from ignition
switch and pull high tension wires off spark plugs
to prevent possibility of accidental starting.
Check snowthrower and traction unit for damage
and defective parts. Make all repairs before re-
starting the engine and operating the unit.
16. Clear snow from slopes by going up and down;
never across the face, and use caution when
changing directions. Never clear snow from steep
slopes.
17. Do not touch engine, muffler or its adjacent
shroud while engine is running or soon after it is
stopped. These areas could be hot enough to
cause a burn,
18. Before getting off the seat:
A. Move traction speed control lever to
neutral position and remove hand from
lever.
B. Set the park lock and disengage the
implement clutch lever.
C. Shut the engine off and remove key from
ignition switch. Wait for all movement to
stop before getting off the seat.

INSTALL BALLAST IN REAR BOX
A WARNING
The Groundsmaintenance Tractor, when
operated with the snowthrower in the
raised or transport position, will be
seriously degraded in forward stability
and steering control without the addition
of 425 pounds (193 kg) ballast in the
rear box of the traction unit.
OPERATION
SKID SHOES
The bottom surface of the skid shoes should be
adjusted so they are slightly below the scraper
blade (Fig. 20). This allows scraper blade to
clear cracks, in concrete, paving, etc. and prevents
excessive scraper blade wear (Fig. 20).
A CAUTION
Always adjust skid shoes down to allow
snowthrower to clear gravel or crushed
rock surfaces.
A CAUTION
Never raise implement while auger and
impeller are rotating. The exposed,
rotating auger is hazardous.
