Engine Hazards - Miller Bobcat 250 Owner's Manual

CYLINDERS can explode if
damaged.
Compressed gas cylinders contain gas under high
pressure. If damaged, a cylinder can explode.
Since gas cylinders are normally part of the weld-
ing process, be sure to treat them carefully.
� Protect compressed gas cylinders from excessive heat, mechani-
cal shocks, physical damage, slag, open flames, sparks, and arcs.
� Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
� Keep cylinders away from any welding or other electrical circuits.
� Never drape a welding torch over a gas cylinder.
� Never allow a welding electrode to touch any cylinder.

Engine Hazards

BATTERY EXPLOSION can injure.
� Always wear a face shield, rubber gloves, and pro-
tective clothing when working on a battery.
� Stop engine before disconnecting or connecting
battery cables, battery charging cables (if applica-
ble), or servicing battery.
� Do not allow tools to cause sparks when working on a battery.
� Do not use welder to charge batteries or jump start vehicles unless
the unit has a battery charging feature designed for this purpose.
� Observe correct polarity (+ and -) on batteries.
� Disconnect negative (-) cable first and connect it last.
� Keep sparks, flames, cigarettes, and other ignition sources away
from batteries. Batteries produce explosive gases during normal
operation and when being charged.
� Follow battery manufacturer's instructions when working on or
near a battery. See Battery Service Manual (listed in Safety Stand-
ards) for additional information.
FUEL can cause fire or explosion.
� Stop engine and let it cool off before checking or
adding fuel.
� Do not add fuel while smoking or if unit is near any
sparks or open flames.
� Do not overfill tank — allow room for fuel to expand.
� Do not spill fuel. If fuel is spilled, clean up before starting engine.
� Dispose of rags in a fireproof container.
� Always keep nozzle in contact with tank when fueling.
MOVING PARTS can injure.
� Keep away from moving parts such as fans, belts,
and rotors.
� Keep all doors, panels, covers, and guards closed
and securely in place.
� Stop engine before installing or connecting unit.
� Have only qualified persons remove doors, panels, covers, or
guards for maintenance and troubleshooting as necessary.
� To prevent accidental starting during servicing, disconnect nega-
tive (-) battery cable from battery.
� Keep hands, hair, loose clothing, and tools away from moving
parts.
� Reinstall doors, panels, covers, or guards when servicing is fin-
ished and before starting engine.
� Before working on generator, remove spark plugs or injectors to
keep engine from kicking back or starting.
� Block flywheel so that it will not turn while working on generator
components.
� Never weld on a pressurized cylinder — explosion will result.
� Use only correct compressed gas cylinders, regulators, hoses,
and fittings designed for the specific application; maintain them
and associated parts in good condition.
� Turn face away from valve outlet when opening cylinder valve. Do
not stand in front of or behind the regulator when opening the
valve.
� Keep protective cap in place over valve except when cylinder is in
use or connected for use.
� Use the proper equipment, correct procedures, and sufficient
number of persons to lift, move, and transport cylinders.
� Read and follow instructions on compressed gas cylinders, asso-
ciated equipment, and Compressed Gas Association (CGA) publi-
cation P-1 listed in Safety Standards.
EXHAUST SPARKS can injure.
� Do not let engine exhaust sparks cause fire.
� Use approved engine exhaust spark arrestor in re-
quired areas — see applicable codes.
HOT PARTS can burn.
� Do not touch hot parts bare handed.
� Allow cooling period before working on equipment.
� To handle hot parts, use proper tools and/or wear
heavy, insulated welding gloves and clothing to
prevent burns.
STEAM AND HOT COOLANT can
burn.
� If possible, check coolant level when engine is cold
to avoid scalding.
� Always check coolant level at overflow tank, if
present on unit, instead of radiator (unless told otherwise in main-
tenance section or engine manual).
� If the engine is warm, checking is needed, and there is no overflow
tank, follow the next two statements.
� Wear safety glasses and gloves and put a rag over radiator cap.
� Turn cap slightly and let pressure escape slowly before completely
removing cap.
Using a generator indoors CAN KILL
YOU IN MINUTES.
� Generator exhaust contains carbon monoxide.
This is a poison you cannot see or smell.
� NEVER use inside a home or garage, EVEN IF
doors and windows are open.
� Only use OUTSIDE and far away from windows, doors, and vents.
BATTERY ACID can BURN SKIN and
EYES.
� Do not tip battery.
� Replace damaged battery.
� Flush eyes and skin immediately with water.
ENGINE HEAT can cause fire.
� Do not locate unit on, over, or near combustible
surfaces or flammables.
� Keep exhaust and exhaust pipes way from
flammables.
