SAFETY
CONTACT WITH THE ROTATING BLADE--This accident usually
happens when the operator is clearing the discharge chute
of grass, (especially when the grass is wet), or when the
operator adjusts the machine without turning it off and
waiting for the blades to completely stop.
PROPELLED OBJECTS-~Sticks, rocks, wires and other objects
can be propelled out through the discharge chute or from
under the mower housing. Bystanders are particularly
vulnerable.
GRASS CATCHER OR GUARD--The mower shall not be operated
without either the entire grass catcher or the guard in
place. | | |
OVERTURNING--This happens when riding mowers are used on
steep slopes, embankments or hills. The operator in these
cases can come in contact with the blades or sustain
injuries during a fall.
MOWER RUNNING OVER THE VICTIM--This usually happens when
a riding mower is driven in reverse. The accident
victims are most often young children whom, unseen by the
operator of the mower, were in the area being mowed.
AT SNAPPER, WE SHARE YOUR DESIRE TO PROTECT YOURSELF,
YOUR FAMILY, YOUR FRIENDS AND YOUR NEIGHBORS FROM ACCIDENTAL
INJURY. OBSERVING AND ENFORCING THE FOLLOWING GUIDELINES WILL
HELP TO INSURE THE SAFETY OF EVERYONE.
PLEASE BE CAREFUL!
10.
PEOPLE WHO OPERATE, SERVICE, OR ARE OTHERWISE ASSOCIATED with )
the Snapper ZU Rider should be trained in its proper use and
warned of its dangers. Before operating, adjusting, or
servicing the Snapper Unistat Mower they should read and
understand this entire manual and the owner's engine manual.
AVOID CONTACT WITH MOVING PARTS. Keep hands and feet from
under mowing deck and away from blades at all times. Turn
engine (motor) off if you must unclog the chute.
KEEP YOURSELF AND ALL OTHERS AWAY FROM THE DISCHARGE CHUTE at
all times. Never direct the discharge of material toward
bystanders. Never allow anyone near the machine while in
operation.
AVOID HILLS AND SLOPES. Use extreme caution when mowing up or
down slopes. NEVER mow across the face of a slope. If a slope
must be ascended, back up the slope; drive forward when
descending. Reduce speed and use caution to start, stop and
maneuver. To prevent loss of control on a slope avoid sharp
turns, sudden changes in direction, and sudden stops and
starts.
DISENGAGE POWER TO MOWER BEFORE BACKING UP. Do not mow in
reverse unless ABSOLUTELY necessary and then only after turning
around and observing the entire area behind the mower. Go o
slowly. Most "running over a victim" accidents occur in
reverse.
BEGINNING OPERATORS SHOULD LEARN HOW TO STEER the Snapper ZU
Rider before attempting to mow. Start with slow engine speed
and drive without the blades engaged in open area until
comfortable with the machine.
KNOW HOW TO STOP QUICKLY. Know the location and operation of
every control, especially how to brake and how to disengage the
mower blades.
DO NOT MOVE THE STEERING LEVERS from forward position to
reverse position rapidly. The speed and/or direction of travel
is affected instantly by the movement of the steering levers.
DO NOT ALLOW CHILDREN TO OPERATE MOWER. Do not allow others
who have not had instruction to operate mower.
ALWAYS TURN ENGINE OFF AND REMOVE THE KEY before leaving the
mower to prevent children and inexperienced operators from
starting the engine. Never leave the mower unattended with
engine running. Always wait for all moving parts and all
sounds to stop before leaving the operator's seat. Always set
the parking brake on an unattended mower. O

WEAR STURDY, ROUGH-SOLED WORK SHOES AND CLOSE-FITTING SLACKS
and shirts. Never operate the mower in bare feet, sandals or
sneakers. |
NEVER CARRY PASSENGERS.
KNOW THE AREA YOU ARE TO MOW. Watch for hidden dangers such as
rocks, roots, sticks, holes, bumps and drop-offs, etc. Before
mowing, pick up all debris in area to be mowed. Sharp and hard
objects can be propelled at a high speed and can act like
schrapnel. Walk through tall grass BEFORE MOWING to make sure
there are no hidden dangers. Mow higher than desired in tall
grass to expose any hidden objects and/or obstacles, clean the
area, and then mow to the desired height.
NEVER REFUEL A MOWER INDOORS. Allow the engine time to cool
before refueling. Unseen vapors may be ignited by a spark.
Always clean up spilled gasoline. Never run the engine indoors
in a garage or any other closed building. Allow engine to cool
before storing in any enclosure. The engine exhaust and the
gasoline fumes are dangerous.
NEVER REMOVE THE FUEL CAP or add gasoline to a running or hot
engine or an engine that has not been allowed to cool for
several minutes after running. Always make sure the gas cap is
in place. |
DON'T SMOKE AROUND THE MOWER or the gasoline storage
container. Gasoline fumes can easily ignite.
KEEP GASOLINE IN A WELL-VENTILATED AREA away from your living
quarters and in tightly-capped safety cans. Never store mower
with gasoline in the tank inside a building where fumes may
reach an open flame or spark.
DISENGAGE BLADE, STOP ENGINE AND REMOVE IGNITION KEY before any
servicing. Be sure all moving parts and all sounds have
stopped. Let engine cool and disconnect the spark plugs so the
engine cannot start by accident. A SLIGHT ROTATION OF THE BLADE
COULD START THE ENGINE. |
КЕЕР ALL NUTS, BOLTS, AND SCREWS TIGHT to be sure equipment is
in safe working condition, especially blade mounting bolts.
VEHICLE SHOULD BE STOPPED AND INSPECTED FOR DAMAGE after
striking a foreign object and the damage should be repaired
before restarting and operating the equipment. Stop immediately
and check for damage or loose parts if mower should start
vibrating. |

switches become inoperable, have them repaired immediately.
DON'T STEP OR STAND ON THE MOWER HOUSING; step or stand only on
the foot deck.
WATCH OUT FOR TRAFFIC near roadways and when crossing roads.
THIS MACHINE IS NOT MEANT FOR HIGHWAY or street use. It is not
a recreational vehicle and it should not be operated as such.
DO NOT USE MOWER WHEN GRASS IS WET OR SLIPPERY.
KEEP MACHINE AND ENGINE CLEAN -- free of grease, dirt, grass,
leaves and other foreign build-up to reduce overheating and a
possible fire hazard. |
MOW ONLY DURING DAYLIGHT.
ALWAYS DISENGAGE THE MOWER BLADE CLUTCH when transporting.

Keep the electrolyte level above the plates in each cell by
adding distilled water as it becomes necessary. Add water just
before operating the mower to mix the water with the solution. Be
careful not to overfill the battery--the electrolyte solution is
corrosive and can cause damage to surrounding metal parts if it
should spill. Keep your battery at 1.268 specific gravity charge.
When taking the battery out of the mower for servicing, make sure
to connect the cables to the battery exactly as they were prior to

drain plugs from both pump and motor housings on
Unistat. Allow the fluid to drain out. Remove the
filter at this time.
b. Reinstall the bottom drain plugs and new filter.
c. Refill Unistat through the reservoir. This will
require approximately 7 quarts of the ATF.

approximately 1/4" to 1/2" under moderate pressure. Do
not over tighten.
с. Retighten the nuts holding the pulleys to lock the
adjustment. Tighten tensioning bolt 1/4 turn to set
lockwasher. This will prevent loosening of tension
bolt.
