GASOLINE
IMPORTANT: ALWAYS use gasoline that
meets the following guidelines:
• Clean, fresh gasoline.
• A minimum of 87 octane/87 AKI (91
RON). High altitude use may require a
different octane. Consult your engine
manual.
• Gasoline with up to 10% ethanol
(gasohol) or up to 15% MTBE (methyl
tertiary butyl ether) is acceptable.
• Use of any gasoline other than those
approved above may void the engine
warranty. If the pumps are not marked
for the content of alcohol or ethers,
check ethanol and MTBE levels with
the fuel supplier.
• Do not modify the fuel system to use
different fuels.
• Never mix oil and gasoline.
NOTE: All gasoline is not the same. If the
engine experiences starting or performance
problems after using a new gasoline, switch
to a different fuel provider or fuel brand.
IMPORTANT: Excessively oxygenated or
reformulated fuels (fuels blended with
alcohols or ethers) can damage the fuel
system or cause performance problems. If
any undesirable operating problems occur,
use a gasoline with a lower percentage of
alcohol or ether.
Fuel Stabilizer
Gasoline left in the fuel system for extended
periods without a stabilizer will deteriorate,
resulting in gum deposits in the system.
These deposits can damage the carburetor
and the fuel hoses, filter and tank. Prevent
deposits from forming in the fuel system
during storage by adding a quality fuel
stabilizer to the fuel. Follow the
recommended mix ratio found on the fuel
stabilizer container.
To add fuel to fuel tank:
1. Put unit in open or well-ventilated area.
2. Stop engine and allow to cool.
3. Clean fuel cap and surrounding area.
4. Remove cap.
IMPORTANT: See engine manual for correct
type and grade of fuel.
5. Fill fuel tank. (see SPECIFICATIONS on
page 27page 27 for tank capacity.) Do
not overfill.
6. Replace fuel cap and tighten.
7. ALWAYS clean any spilled fuel.
MOWER SET-UP
CAUTION: DO NOT operate
mower unless either side
discharge cover or side discharge
deflector is installed. Thrown
objects may cause damage or
injury. Never operate unit with
rear door open unless grass bag

CAUTION: If clog or obstruction
prevents grass flow, release
engine/blade control and
disconnect spark plug wire before
attempting to clear away any
clogs.

EMERGENCY STOPPING
To stop the mower in an emergency:
1. Release the engine/blade control.
2. Release the wheel drive control (selfpropelled models).
3. Allow all moving parts to stop before
leaving operator’s position.
STARTING AND SHUT OFF
WARNING: Improper operation
can lead to injury. Learn what the
controls do and how they work.
Thoroughly read and understand
entire Operator Manual.
See Figure 4 for all Controls and Features.
NOTE: Start engine on a level surface that is
free of debris.
Manual Start
1. Check each item under Before Each
Use in the MAINTENANCE SCHEDULE
on page 17.
2. For engines with a primer, push primer
bulb 2 or 3 times for a cold engine.
NOTE: It is unnecessary to prime or choke a
warm engine.
3. For engines with a throttle, place throttle
control in the choke position. Once the
engine has started, place throttle in the
high speed detent.
4. With engine/blade control held against
the handlebar, grasp starter handle and
pull rope slowly until it pulls harder. This
is the compression stroke. Let rope
rewind slowly.
5. Pull rope with rapid continuous full arm
stroke to start engine. Allow rope to
rewind slowly.
IMPORTANT: DO NOT let starter handle
snap against bracket.
6. Repeat steps 4 and 5 until engine starts.
(If engine does not start, see
TROUBLESHOOTING on page 25.)
Shut Off
1. Release wheel drive control and allow
unit to stop completely (self-propelled
models).
2. Release engine/blade control.
Mowing Tips
Cut grass when it is dry.
Keep mower blades sharp.
Do not set cutting height too low. For tall
grass, mow twice.
Do not mow too fast.
Mow with engine at full throttle. Discharge
clippings into areas already cut.
Vary cutting pattern with each mowing.
NOTE: To prevent dirt and grass from
collecting on mower pan, avoid operating
over bare ground with only patches of grass.
Mulching Tips
For best mulching performance, cut no more
than 1 inch (2.54 cm) of grass per cutting.

The unit must stop quickly and completely
when the control is released. Adjust or repair
if necessary. See WHEEL DRIVE CONTROL
ADJUSTMENT on page 22.
CHECK GRASS BAG
Check grass bag frequently for wear or
deterioration. Replace worn or damaged bag
with an Ariens original equipment
replacement bag only.
CLEAN UNIT
Before each use clean unit, muffler and
engine surfaces of debris, oil or fuel spills to
ensure proper cooling and prevent fires.
CHECK ENGINE OIL
IMPORTANT: Maintain proper oil level at all
times or engine damage will result.
Check the level of the engine crankcase oil
before each use.
Make sure engine is level when checking oil.
See engine manual for instructions.
CHECK MOWER BLADE
See Figure 11.
Check blade mounting: blade must be secure
and bolt torqued to 37.5 – 50 lbf-ft (51 –
68 N•m) (bolt should fully compress lock
washer).Check blade for nicks and dull
cutting edges. Sharpen if necessary.
Check blade for rounded or broken ends,
thinned metal or other damage. Replace if
necessary.
NOTE: Blades should be sharpened and
balanced professionally. Contact your Ariens
Dealer.
To remov e blade:
1. Stop engine, wait for all moving parts to
stop, and disconnect spark plug wire.
2. Block blade to prevent rotation.
3. Remove bolt, lock washer, flat washer
and blade from shaft.
To install blade:
1. Replace blade, flat washer, lock washer
and bolt on shaft.
2. Torque bolt to 37.5 – 50lbf-ft (51 –
68 N•m) (bolt should fully compress lock
washer).
3. Connect spark plug wire.
Sharpen the Mower Blades
CAUTION: DO NOT sharpen
mower blades while on unit. An
imbalanced mower blade will
cause excessive vibration and
eventual damage to unit. Check
mower blade balance before
reinstalling blades.
NEVER weld or straighten bent
blades.
1. Remove mower blade from unit.
Discard mower blade if:
• More than 1/2 in. (1.27 cm) of metal is
removed.Air lifts become eroded.
• Blade is bent or broken.
2. Sharpen mower blade by removing an
equal amount of material from each end
of mower blade. DO NOT change angle
of cutting edge or round the corner of the
mower blade.

Slide mower blade on an unthreaded
bolt. A balanced blade should remain in
a horizontal position. If either end of
mower blade moves downward, sharpen
the heavy end until blade is balanced
(Figure 12).
4. Install mower blade on unit.
5. Tighten the bolts to a torque of 37.5 50 lbf-ft (51-68 N•m).

CHECK DRIVE BELT
(Self-Propelled Models)
Check drive belt and replace if worn or
damaged. See DRIVE BELT
REPLACEMENT on page 20.
CHECK FASTENERS
Check all fasteners for proper tightness. Pay
special attention to blade hardware and all
guards, shields and safety devices.
CHECK AIR CLEANER
See engine manual for specific information.
CHANGE ENGINE OIL
IMPORTANT: Change engine crankcase oil
after first five (5) hours of operation. Then
change oil after every 25 hours of operation.
Refer to engine manual for instructions and
proper oil type.

lube fittings. Order P/N: 00036800 - 3 pack of
3 oz. cartridges.
CHECK SPARK PLUG
Spark plug should be replaced every 100
hours of operation or each year.
NOTE: Loose spark plug wire terminals can
cause sparking. Replace terminal if
damaged.
CHECK ENGINE COOLING
WARNING: HOT SURFACES can
cause death or serious injury. DO
NOT TOUCH parts which are hot
from operation. ALWAYS allow
parts to cool.
To prevent overheating, air must circulate
freely around the cooling fins, cylinder head
and block.
Every 100 hours of operation or yearly (more
often if conditions require) remove blower
housing and clean cooling fins. See engine
manual for instructions.
CHECK MUFFLER
Check muffler for debris, cracks, wear, or
other damage.
