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.
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.
Follow First Aid directions for contact with
battery fluid.
• External Contact: Flush with water.
• Eyes: Flush with water for at least 15
minutes and get medical attention
immediately!
• Internal Contact: Drink large quantities of
water. Follow with Milk of Magnesia,
beaten egg or vegetable oil. Get medical
attention immediately!
• In case of internal contact, DO NOT
induce vomiting!
Before tipping unit up onto housing, remove
fuel so no spills will occur and remove battery.
Ensure unit is secure and will not tip over
during maintenance.
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.
Keep all hardware properly tightened. Check
shear bolts frequently.
Maintain or replace safety and instruction
labels, as necessary.
NEVER store unit with fuel in fuel tank, inside
a building where any ignition sources are
present.
Shut off fuel and allow engine to cool
completely before storing in closed area or
covering unit.
For extended storage, clean unit thoroughly.
See Engine Manual for proper storage.
Use only attachments or accessories
designed for your unit.

RUNNERS
Runners should be adjusted (Figure 15) as
conditions require.
1. Position unit on a hard, flat, smooth level
surface.
2. Adjust runners by inserting a spacer of
desired thickness under center of scraper
blade, loosen runner hardware, slide
runners to flat surface. Allow 1/8 in.
(3 mm) between scraper blade and hard
smooth surfaces. Allow 1-1/4 in. (30 mm)
between scraper blade and uneven or
gravel surfaces. Retighten hardware.
NOTE: Keep housing level by adjusting
runners equally.
SCRAPER BLADE
IMPORTANT: Damage to auger/impeller
housing will result if blade wears down too far.
Scraper blade is adjustable to compensate for
wear.
To adjust scraper blade:
1. Tip unit back onto handlebar, support
housing and loosen nuts retaining blade.
2. Adjust runners to fully raised position
(housing closest to ground).
3. Reposition scraper blade flush with
runners and tighten lock nuts.
SHEAR BOLTS
IMPORTANT: Use only Ariens shear bolts for
replacement. Use of any other type of shear
bolt may result in severe damage to unit.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger,
breaking shear bolts (Figure 16) which secure
the auger to the shaft. This allows auger to
turn freely on the shaft preventing damage to
gear drive.
For Replacement:
1. Slide auger outward against roll pin and
align hole in shaft with hole in auger
(holes in shaft for roll pins and shear bolts
line up).
2. Drive shear bolt through hole (if shear bolt
was broken this will drive remaining part
from shaft).
3. Secure shear bolt with nut.
