Gas Engine Precautions - AIRLESSCO HSS 9000 Service & Operation Manual

GAS ENGINE PRECAUTIONS

Gasoline & its vapors are extremely flammable & explosive.Fire or explosion can cause severe burns or death.
WHEN ADDING FUEL
• Turn engine OFF and let engine cool at least 2
minutes before removing gas cap.
• Fill fuel tank outdoors or in well ventilated area.
• Do not overfill fuel tank. Fill tank to approximately
11⁄2 inches below top of neck to allow for fuel
expansion.
• Keep gasoline away from sparks, open flames, pilot
lights, heat and other ignition sources.
• Check fuel lines, tank, cap and fittings frequently for cracks
or leaks. Replace if necessary.
WHEN STARTING ENGINE
• Make sure spark plug, muffler, fuel cap & air cleaner are in place.
• Do not crank engine with spark plug removed.
• If fuel spills, wait until it evaporates before starting engine.
• If engine floods, set choke to OPEN/RUN position, Place throttle
in FAST and crank until engine starts.
WHEN OPERATING EQUIPMENT
• Do not tip engine or equipment at angle which
causes gasoline to spill.
• Do not choke carburetor to stop engine.
WHEN TRANSPORTING EQUIPMENT
• Transport with fuel tank EMPTY or with fuel shut-off
valve OFF.
WHEN STORING GASOLINE OR EQUIPMENT WITH
FUEL IN TANK
• Store away from furnaces, stoves, water heaters and
other appliances that have pilot lights or other ignition
source. They can ignite gasoline vapors.
Starting engine creates sparking.
Sparking can ignite nearby flammable gases.
Explosion and fire could result.
• When starting engine, pull cord slowly until resistance is
felt, then pull rapidly.
• Remove all external equipment/engine loads before starting
engine.
• Direct coupled equipment components such as, but not
limited to, blades, impellers, pulleys, sprockets, etc. must
be securely attached.
FIGURE 1
Engines give off carbon monoxide, an odorless,
colorless, poison gas.
Breathing carbon monoxide can cause nausea,
fainting or death.
• Start and run engine outdoors.
• Do not start or run engine in enclosed area, even if doors or
windows are open.
Running engines produce heat. Engine parts,
especially mufflers, become extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush,
etc. can catch fire.
• Allow muffler, engine cylinder and fins to cool before touching.
• Remove accumulated combustibles from muffler area and
cylinder area.
• Install and maintain in working order a spark arrester
before using equipment on forest covered, grass covered
and brush covered unimproved land. The state of California
requires this (Section 4442 of the California Public Resources
Code). Other states may have similar laws. Federal laws apply
on federal land.
Unintentional sparking can result in fire
or electric shock.
Unintentional start up can result in entanglement,
traumatic amputation, or lacerations.
BEFORE PERFORMING ADJUSTMENTS OR REPAIRS
• Disconnect spark plug wire and keep it away from
spark plug.
• Disconnect battery at negative terminal (only
engines with electric start).
WHEN TESTING FOR SPARK
• Use approved spark plug tester.
• Do not check for spark with spark plug removal.
