DO NOT operate at too fast a rate. Slow down
before turning.
Stop engine before removing grass catcher or
unclogging chute.
DO NOT mow on wet grass. Reduced traction
could cause sliding.
DO NOT try to stabilize the machine by putting

handle.
ALWAYS keep protective structures, guards
and panels in good repair, in place and

Do not operate without either entire grass
catcher or the discharge guard in place.
DO NOT operate in reverse unless absolutely
necessary. ALWAYS look down and behind
before and while backing; especially for
children.
Follow the manufacturer’s recommendations
for wheel weights or counterweights to
improve stability when using attachments.
NEVER carry passengers–especially
children–even with blades off.
Use extra care when approaching blind
corners or objects that may obscure vision of
hidden obstacles and children.
If you cannot back up a slope or you feel
uneasy on it, do not mow it.
Mow up and down slopes, not across them.
Use slow speed on any slope. Tires may lose
traction on slopes even though the brakes are
functioning properly.
Keep all movements on the slope slow and
gradual. DO NOT make sudden changes in
speed or direction.
Use extra care while operating machines with
grass catcher or other attachments. They can
affect stability of the machine.
Avoid starting, stopping, or turning on a slope.
If tires lose traction, disengage the blades and

truck or trailer bed with a plastic liner. Always
place containers on the ground away from
your vehicle before filling.
When practical, remove gas-powered
equipment from the truck or trailer and refuel it
on the ground. If this is not possible, then
refuel such equipment on a trailer with a
portable container, rather than from a gasoline
dispenser nozzle.
Keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete. Do not use a nozzle lock-
open device.
If fuel is spilled on clothing, change clothing
immediately.
Avoid Electric Shock. Objects contacting both
battery terminals at the same time may result
in injury and unit damage. DO NOT reverse
battery connections.
Explosive Gases from battery can cause
death or serious injury. Poisonous battery fluid
contains sulfuric acid and its contact with skin,
eyes or clothing can cause severe chemical
burns.
NO flames, NO sparks, NO smoking near
battery.
ALWAYS wear safety glasses and protective
gear near battery.

GB - 9
DO NOT TIP battery beyond a 45˚angle in any
direction.
ALWAYS keep batteries out of reach of
children.
Battery posts, terminals and related
accessories contain lead and lead
compounds, chemicals known to the State of
California to cause cancer and reproductive
harm. Wash hands after handling.
Reverse connections may result in sparks
which can cause serious injury. Always
connect positive (+) lead of charger to positive
(+) terminal, and negative (-) lead to negative
(-) terminal.
ALWAYS disconnect negative (-) cable FIRST
and positive (+) cable SECOND. ALWAYS
connect positive (+) cable FIRST, and negative
(-) cable SECOND.
A frozen battery can explode and result in
death or serious injury. DO NOT charge or
jump start a battery containing frozen fluid.
Thaw the battery before putting on a charger
or jump starting.
ALWAYS keep protective structures, guards,
and panels in good repair, in place and
securely fastened. NEVER modify or remove
safety devices.
DO NOT change engine governor settings or
over-speed engine.
Fumes from engine exhaust can cause injury
or death. DO NOT run engine in an enclosed
area. Always provide good ventilation.
ALWAYS maintain unit in safe operating
condition. Damaged or worn out muffler can
cause fire or explosion.
Stop and inspect equipment if you strike an
object or if there is an unusual vibration.
Repair, if necessary, before restarting. Never
make adjustments or repairs with the engine
running.
Mower blades are sharp and can cut you.
Wrap the blade(s) or wear gloves, and use
extra caution when servicing them. NEVER
weld or straighten mower blades.
Rotation of one blade may cause rotation of
the other blades.
Check brake operation frequently. Adjust and
service as required.
Keep all hardware properly tightened.
Stored energy in springs can cause injury.
Maintain or replace safety and instruction
labels, as necessary.
Never store the machine or fuel container

within 1/4 inch (6.35 mm).
•If mower deck is not level, repeat steps 5
and 6.
•If mower deck is level, record the
distance from rear edge of mower
blades to the ground and then adjust
pitch of mower deck.
Adjust Pitch of Mower Deck
IMPORTANT: The mower blade end used to
level the mower deck must be used to adjust
the pitch of the mower deck.
1. Rotate the right and left mower blades
180 degrees until the end of the mower
blade that was used to level the mower
deck is facing forward (figure 16).
NOTE: The front blade cutting height (item 4)
should be 1/16 - 1/4 in. (1.59 - 6.35 mm) lower
than the rear blade cutting height (item 6)
(figure 16).
2. Measure from front edge of right and left
mower blades to the ground.
3. Subtract front blade cutting height
(item 4) measurement from rear blade
cutting height (item 6) measurement
(figure 16).
4. Perform steps 5 through 7 if the front
blade cutting height (item 4) is too high or
too low on either side on either side of
mower deck.

SHARPENING MOWER BLADE
1. Remove mower blade from unit (see
Mower Blade Replacement on page 20).
Ariens recommends having mower blades
sharpened by a professional. Contact your
Ariens dealer.
Discard mower blade if (figure 18):
•more than 1/2 in. (1.27 cm) of metal is
removed.
•the air lift erosion area (item 1) is eroded.
•the mower blade is bent or broken.
Do not change angle of cutting edge (item 2)
or round the corner at the end of mower blade.
2. Sharpen mower blade by removing an
equal amount of material from each end
of mower blade.
3. Check mower blade balance by sliding
mower blade on an unthreaded bolt. If
blade is balanced, it should remain in a
horizontal position. If either end of mower
blade moves downward, sharpen the
heavy end until mower blade is balanced
(figure 19).
4. Install mower blade on unit (see Mower
Blade Replacement on page 20).
CAUTION: Mower blades are sharp
and can cut you. Wrap the blades or
wear gloves, and use extra caution
when servicing them.
CAUTION: DO NOT sharpen mower
blade while on unit. An unbalanced
mower blade will cause excessive
vibration and eventual damage to unit.
Check mower blade balance prior to
reinstalling mower blades.
NEVER weld or straighten mower
blades.
