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.
Check fuel supply before starting engine.
DO NOT fill gasoline tank indoors, when
engine is running, or while engine is hot.
Allow engine to cool several minutes before
removing fuel cap.
DO NOT overfill. Allow about 1/4" (6 mm) of
tank space for fuel expansion.
Replace gasoline tank cap securely and
clean any spilled fuel before starting engine.
If fuel is spilled on clothing, change clothing
immediately.
NEVER store fuel inside where there is an
open flame, such as a water heater.
ALWAYS drain fuel outdoors away from
ignition sources.
ALWAYS shut off engine, and remove key,
and close fuel shutoff valve when transporting
unit on a truck or trailer.
Avoid Electric Shock. DO NOT disconnect
wire from spark plug while engine is running.
Do NOT put battery in fire or mutilate.

NO flames, NO sparks, NO smoking, near
battery.
Poisonous battery fluid contains sulfuric acid.
Contact with skin, eyes or clothing can cause
severe chemical burns.
ALWAYS wear safety glasses and protective
gear near battery.
ALWAYS keep batteries out of reach of
children.

OPERATION
CONTROLS AND FEATURES
See Figure 5 for locations.
WARNING: Improper operation
can lead to injury. Learn what the
controls do and how they work.

CAUTION: AVOID INJURY. Read
and understand the entire Safety
section before proceeding.
Engine/Blade Control
CAUTION: Check function of
Engine/Blade Control regularly.
Improper function of control could
cause injury.
The engine/blade control must be held
against the handlebar to start the engine and

engine and blade within 3 seconds whenever
operator releases handlebar. Check this
feature frequently. If feature fails to operate,
disconnect spark plug wire and adjust or have
it repaired before using unit.
CAUTION: On self-propelled
models, both rear wheels must be
set at same height or traction drive
may not work properly.

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 8.
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 remove 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 - 50 lbf-ft

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.
3. Check mower blade balance.
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 9).
4. Install mower blade on unit.
5. Tighten the bolts to a torque of 37.5 50 lbf-ft (51-68 N•m).
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.

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.
IMPORTANT: Proper oil level must be
maintained at all times or engine damage will
result. DO NOT overfill. Be sure engine is
level when adding oil.

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.
CAUTION: Replace worn-out
mufflers immediately. Continued
use could result in fire or explosion.
SERVICE AND ADJUSTMENTS

SPEED CONTROL BELL CRANK
The speed control bell crank holds the speed
control rod in position after a speed has been
set. The spring washers may become loose
with normal wear. If the speed control rod
does not stay firmly in position, adjust the
speed control bell crank. See Figure 17.
To adjust:
1. Remove cover, fully compress the
helical spring lock washers with lock
nut and then back lock nut off, one
quarter turn.
2. If the speed control rod is still too
loose, tighten lock nut by small
increments until it holds its position.
Tightening the lock nut too much will
not allow the speed control rod to
move at all.
3. Align notch in left hand side of cover
with bolt and secure with knob.
