1 General Information
Safety

EXHAUST

• Internal combustion engines produce carbon monox-
ide (CO) in the exhaust, which is an odorless, color-
less gas. Carbon monoxide will cause dizziness, nau-
sea, flu-like symptoms, unconsciousness, and even
brain damage or death if breathed for prolonged peri-
ods.
• If exposed to carbon monoxide gas, get to a fresh air
source immediately and seek medical attention. CO
builds up in your blood and can cause lingering
symptoms and permanent damage if left untreated.
• Operate the unit outdoors or in a well-ventilated area,
or pipe exhaust gases out of the work area to an out-
side location where the exhaust can be dissipated
safely away from doors, windows, air conditioners, or
other potential sources of outside-air intake that could
permit re-entry of hazardous fumes.
• Never enter an enclosed area where an engine has
been running and exhaust gases have been allowed
to collect. Open adjacent windows or doors first to
permit outside air to ventilate the area, and allow suf-
ficient time for a complete air exchange to occur.

BATTERY

• Lead-acid batteries use an electrolyte containing sul-
phuric acid, a highly corrosive liquid that can cause
severe chemical burns if allowed to come into contact
with your skin, or blindness if allowed to contact your
eyes. Always wear approved eye goggles or a full
face shield and protective gloves when handling elec-
trolyte or filling the battery.
• Lead-acid batteries also produce hydrogen, a color-
less, highly explosive gas that can be easily ignited
by a single spark. Charging the battery incorrectly or
hooking up jumper cables improperly can cause
sparking, and must be avoided. Always follow recom-
mended battery charging and jumper cable proce-
dures.
• When removing or installing battery cables, disconnect
the negative cable FIRST, and reconnect it LAST. If
not done in this order, the positive terminal could be
accidentally shorted to the frame by a tool, creating a
dangerous spark that can ignite nearby fuel vapors or
escaping hydrogen gas from the battery.
• Keep battery securely fastened in position with vent
tube directed down and out of battery compartment.
Replace battery if electrolyte leakage occurs. Make
sure the battery vent tube is properly installed and is
not plugged with clippings or other debris. Replace the
vent tube if cracked, damaged, or missing from unit.
• Old batteries should be disposed of by recycling.

ELEVATION OF UNIT

• Always support unit on approved jack stands when
working on an elevated unit, and keep unit from
rolling by engaging parking brake and placing wheel
chocks behind wheels still on floor or work table.
• Secure unit to work-surface of scissor-lift work tables
or other powered lift tables in accordance with the
manufacturer's instructions. Unsecured units may roll
unexpectedly while work is being done, causing
injuries.
• Never work under an elevated unit unless it is proper-
ly supported by jack stands, locked from rolling with
wheel chocks or equivalent, and you can quickly
escape from under the unit in an emergency using a
rolling device such as a mechanic's creeper.
• Always protect your eyes from flying and falling
debris or small parts by wearing approved safety
glasses or goggles.
• Remove the ignition key and disconnect the spark
plug wires before working under a unit. Accidental or
inadvertent starting could result in serious injuries.

ELECTRICAL SYSTEM

• Loose connectors, worn wires, damaged wire insula-
tion, and loose termination hardware can cause
sparks, short circuits, and erratic equipment operation.
Always check wiring for damage, and make appropri-
ate repairs before placing unit back into operation.
• Use care when working around exposed terminals to
prevent short-circuiting the electrical system. Sparking,
electric shocks, and damage to the system may
result from accidental contact between terminals and
metal hand tools.
• Remove all jewelry, watches, rings, keys, and large
metal belt buckles when working on electrical sys-
tems and equipment. Electric shocks and burns can
occur if accidental contact is made to a hot terminal,
in addition to causing a spark. It is also a good prac-
tice to remove jewelry to avoid the possibility of
catching a mechanical moving part.
