this product. Failure to follow all
instructions listed below may result in
electric shock, re, and/or serious
personal injury. When using an electrical
appliance, basic precautions should
always be followed, including the
following:
TRAINING
• Do not allow children under the age of
14 to operate this tool. Children who are
14 years of age or older must read and
understand the operating instructions and
safety rules in this manual and must be
trained and supervised by a parent.
• Read the operating and service instruction
manual carefully. Be thoroughly familiar
with the controls and the proper use of the
appliance. Know how to stop the unit and
disengage the controls quickly.
• Never allow children to operate the
appliance. Never allow adults to operate
the appliance without proper instruction.
• Keep the area of operation clear of all
persons, particularly small children, and

doormats, sleds, boards, wires, and other
foreign objects.
• Do not operate the appliance without
wearing adequate winter garments. Wear
footwear, which will improve footing on
slippery surfaces.
• Adjust the housing height to clear gravel or
crushed rock surface.
• Never attempt to make any adjustments
while the appliance is running (except
where specifically recommended by
manufacturer).
• Always wear safety glasses or eye shields
during operation or while performing an
adjustment or repair to protect eyes from
foreign objects that may be thrown from
the appliance.
• Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting the battery pack, picking up
or carrying the appliance. Carrying the
appliance with your nger on the switch or
energizing appliance that have the switch
on invites accidents.
• Disconnect the battery pack from
the appliance before making any
adjustments, changing accessories, or
storing appliance. Such preventive safety
measures reduce the risk of starting the
appliance accidentally.
• For use only with 2900294ME and other
BAB battery.
• For use only with 2900094ME and other
CAB charger.
• When battery pack is not in use, keep it
away from other metal objects, like paper
clips, coins, keys, nails, screw or other
small metal objects, that can make a
connection from one terminal to another.
Shorting the battery terminals together
may cause burns or a re.
• Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
OPERATION
• Do not put hands or feet near or under
rotating parts. Keep clear of the discharge
opening at all times.
• Exercise extreme caution when operating
on or crossing gravel drives, walks, or
roads. Stay alert for hidden hazards or
trafc.
• After striking a foreign object, turn the
machine off and remove the battery pack,
and then inspect it for damage. Repair any
damage before restarting and using the

Page 5
machine.
• If the appliance should start to vibrate
abnormally, stop the machine and check
immediately for the cause. Vibration is
generally a warning of trouble.
• Stop the machine whenever you leave the
operating position, before unclogging the
collector/impeller housing or discharge
guide, and when making any repairs,
adjustments, or inspections.
• When cleaning, repairing, or inspecting,
make certain the collector/impeller and all
moving parts have stopped.
• Exercise extreme caution when operating
on slopes.
• Never operate the appliance without
proper guards, keep other safety protective
devices in place and working.
• Never direct the discharge toward people
or areas where property damage can
occur. Keep children and others away.
• Don’t Overreach – Keep proper footing and
balance at all times.
• Do not overload the machine capacity by
attempting to clear snow at too fast a rate.
• Don’t Force appliance – It will perform
better and safer at the rate for which it was
designed.
• Never operate the appliance at high
transport speeds on slippery surfaces. Use
care when reversing.
• Never direct discharge at bystanders or
allow anyone in front of the appliance.
• Disengage power to the collector/impeller
when the appliance is transported or not in
use.
• Use only attachments and accessories
approved by the manufacturer of the
appliance (such as wheel weights,
counterweights, or cabs).
• Never operate the appliance without
good visibility or light. Always be sure of
your footing, and keep a firm hold on the
handles.
• Walk, never run.
CLEARING A CLOGGED
DISCHARGE CHUTE
• Hand contact with the rotating impeller
inside the discharge chute is the most
common cause of injury associated with
appliances. Never use your hand to clean
out the discharge chute. To clear the chute:
1. SHUT THE ENGINE(Motor) OFF!
2. Wait 10 seconds to be sure the impeller
SAFETY INSTRUCTIONS
blades have stopped rotating.
3. Always use a clean-out tool, not your
hands.
• If the appliance strikes a foreign object
follow these steps:
1. Stop the appliance. Release the switch.
2. Remove the battery pack.
3. Inspect for damage.
4. Repair any damage before restarting
and operating the appliance.
MAINTENANCE
• Check shear bolts; engine-mounted
bolt, etc., at frequent intervals for proper
tightness to be sure the appliance is in
safe working condition.
• Always refer to owner’s guide instructions
for important details if the appliance is to
be stored for an extended period.
• Store Idle appliances Indoors – When not
in use, the appliances should be stored
indoors in a dry, locked-up place – out of
reach of children.
• Check shear bolts and other bolts at
frequent intervals for proper tightness to
be sure the equipment is in safe working
condition.
• Run the appliance a few minutes after
throwing snow to prevent freeze-up of the
collector/impeller.
• Do not use a battery pack or appliance
that is damaged or modified. Damaged
or modified batteries may exhibit
unpredictable behavior resulting in fire,
explosion or risk of injury.
• Do not expose a battery pack or appliance
to fire or excessive temperature space.
Exposure to fire or temperature above
265°F (130°C) may cause explosion.
• Follow all charging instructions and do
not charge the battery pack or appliance
outside of the temperature range specied
in the instructions. Charging improperly or
at temperatures outside of the specified
range may damage the battery and
increase the risk of re.
• Recharge only with the charger specified
by the manufacturer. A charger that is
suitable for one type of battery pack may
create a risk of re when used with another
battery pack.
• Use appliances only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury

Page 6
and re.
• Have servicing performed by a qualified
repair person using only identical
replacement parts. This will ensure that the
safety of the product is maintained.
• Do not modify or attempt to repair
the appliance or the battery pack (as
applicable) except as indicated in the
instructions for use and care.
