8
Safety Instructions
7. Prolonged exposure to loud noise can cause im-
pairment or loss of hearing. Operator hearing
protection is recommended. Wear a suitable
hearing protective device, such as earmuffs or
earplugs.
8. Keep all protective shields and safety devices
in place. If a protective shield, safety device, or
decal is damaged, unusable, or missing, repair or
replace it before operating the machine.
9. Be sure interlock switches are functioning
correctly, so the engine cannot be started un-
less the Forward Speed Control lever is in the
NEUTRAL-PARK position, and the PTO clutch is
in the DISENGAGED position. Also, the engine
should stop if the operator lifts off the seat with
either the Forward Speed Control (FSC) out of
the NEUTRAL-PARK position or the PTO clutch
in the ENGAGED position.
10. Handle gasoline with care. Gasoline is highly
ammable and its vapors are explosive:
a. Use an approved fuel container.
b. Never add fuel to a running engine or hot
engine (allow hot engine to cool several
minutes).
c. Keep matches, cigarettes, cigars, pipes,
open ames, or sparks away from the fuel
tank and fuel container.
d. Always ll the fuel tank outdoors using care.
Fill to about one inch from the top of the tank.
Use a funnel or spout to prevent spilling.
e. Replace the machine fuel cap and contain-
er cap securely and clean up any spilled fuel
before starting the engine.
11. Never attempt to make any adjustments while
the engine is running, except where specically
instructed to do so.
12. The snow or leaves can sometimes hide objects
that might clog the snowblower or debris blow-
er chute, or otherwise cause damage. Clear the
area of doormats, sleds, boards, wires and other
debris.
13. The electrical system battery contains sulfuric
acid. Avoid any contact with skin, eyes, and
clothing. Keep the battery and acid out of reach
of children.
WARNING
This product can expose you to
chemicals including Phenylethane which is
known to the State of California to
cause cancer, and N-Methyl-2-Pyrrolidone,
which is known to the State of California
to cause birth defects or other reproductive
harm. For more information go to www.
P65Warnings.ca.gov.
OPERATING
NOTE: Refer to your tractor Operator’s Manual for
safety instructions for operating the tractor.
1. Operate the machine only in daylight or in
good articial light with good visibility of areas
being cleaned.
2. Sit on the seat when starting the engine and op-
erating the machine. Keep feet on footrests at
all times when the tractor is moving and/or the
implement is operating.
3. For a beginning operator, learn to steer (ma-
neuver) the tractor with a slow engine speed
before attempting any implement operation.
Be aware that, with the front mounted implement
conguration, the back of the machine swings to
the outside during turns.
DANGER
Do not operate around overhanging tree
branches or bushes at the same height as
the operator’s torso and head where inad-
vertent contact may cause injury.
4. Remember, for an emergency stop, the forward
motion of the tractor can always be stopped by
pulling the Forward Speed Control (FSC) into the
NEUTRAL-PARK position.
9
Safety Instructions
5. In case the transmission drive belt breaks during
operation, and if the machine is on a slope, the
machine will freewheel down the slope. To
maintain control, immediately (1) Release the
steering levers and simultaneously (2) Move the
FSC to the NEUTRAL-PARK position. When
the machine is stopped or moving slowly, en-
gage the parking brake.
NOTE: The emergency stop procedure is exactly
the same procedure used to normally stop and
park the machine.
6. Disengage the PTO clutch and put the FSC in
the NEUTRAL-PARK position before starting
the engine (an ignition interlock switch normally
prevents starting of the tractor if these controls
are in the OPERATING position).
7. Do not operate the machine if the operator
presence safety switch system is not work-
ing. Verify proper operation by having the oper-
ator lift off the seat with the engine running and
moving two controls, one at a time; (1) Move the
FSC lever out of the NEUTRAL-PARK position,
and (2) Engage the PTO Clutch. Moving either
control should stop the engine immediately.
8. Do not run the engine in a conned area with-
out adequate ventilation. Exhaust fumes are
hazardous and can be deadly.
9. Do not carry passengers - maximum seating
capacity is one (1) person.
10. Avoid sudden starts or stops. Before backing
the machine up, look to the rear to be sure no
one is behind the machine. Watch carefully for
trafc when crossing or working near roadways.
11. When moving forward, do not suddenly put the
tractor in reverse by rapidly pulling on the steer-
ing levers, especially when going downhill, as this
can lift the tractor tail wheel off the ground and
set up a bucking motion due to operator over-
control. If bucking does occur, immediately stop
the bucking action by pulling the Forward Speed
Control (FSC) lever into the NEUTRAL-PARK
position.
12. Disengage the PTO clutch when transporting the
machine.
13. Do not operate across the face of slopes. Use
extreme caution when changing direction on
slopes. Do not attempt to operate on steep
slopes.
14. Never adjust gauge wheels or skid shoes with
the engine running. Before adjusting height or
servicing, disengage the PTO clutch, stop the
engine, and remove the ignition key. Wait for all
movement to stop before getting off the seat.
NOTE: The PTO brake should stop drive line
rotation within ve (5) seconds of disengaging
the PTO clutch. If the brake is not functioning
properly, have it repaired by an authorized
dealer immediately.
15. If the implement strikes a solid object or the ma-
chine begins to vibrate abnormally, immediately
disengage the PTO clutch, stop the engine,
and wait for all moving parts to stop. Dis-
connect the fuel solenoid wire [diesel engines]
or the spark plug wire(s) [gasoline engines] to
prevent accidental starting. Thoroughly inspect
the implement and repair any damage before re-
starting the engine and operating the machine.
Make sure implement components are in good
condition and all bolts are tight.
16. Do not touch the engine or mufer while the
engine is running or immediately after stopping
the engine. These areas may be hot enough to
cause serious burns.
17. When leaving the machine unattended, disen-
gage the PTO clutch, stop the engine, and re-
move the ignition key.
MAINTENANCE
NOTE: Refer to your tractor Operator’s Manual for
safety instructions for tractor maintenance.
1. To prevent accidental starting of the engine
when servicing or adjusting the machine, re-
move the key from the ignition switch and dis-
connect the fuel solenoid wire [diesel engines] or
the spark plug wire(s) [gasoline engines].
2. To reduce re hazards, keep the engine free of
grass, leaves, excessive grease, and dirt.
3. Keep all nuts, bolts, and screws tight to ensure
the machine is in a safe, working condition.
4. Perform only maintenance instructions de-
scribed in this manual. Unauthorized mainte-
nance operations or machine modications may
result in unsafe operating conditions.
5. If the engine must be running to perform a main-
tenance adjustment, keep hands, feet and
clothing away from moving parts. Do not
wear jewelry or loose clothing.
10
Safety Instructions
6. Always use proper engine service manuals
when working on the engine. Unauthorized
maintenance operations or modications to the
engine may result in unsafe operating condi-
tions.
7. Altering the machine in any manner which ad-
versely affects its operation, performance, du-
rability or use will VOID the warranty and may
cause hazardous conditions.
8. Never attempt to disconnect any safety devices
or defeat the purpose of these safety devices.
9. Do not change the engine governor settings or
overspeed the engine. The governor has been
factory-set for maximum-safe engine operating
speed.
