Page: 4 / 74

If any portion of this manual is not understood, contact the nearest
Dealer for starting, operating and servicing procedures.
Throughout this publication, and on tags and decals affixed to the
equipment, DANGER, WARNING, CAUTION and NOTE blocks are
used to alert personnel to special instructions about a particular
operation that may be hazardous if performed incorrectly or care-
lessly. Observe them carefully. Their definitions are as follows:
INDICATES A HAZARDOUS SITUATION OR ACTION WHICH, IF NOT
AVOIDED, WILL RESULT IN DEATH OR SERIOUS INJURY.
Indicates a hazardous situation or action which, if not
avoided, could result in death or serious injury.
Indicates a hazardous situation or action which, if not
avoided, could result in minor or moderate injury.
NOTE:
Notes contain additional information important to a proce-
dure and will be found within the regular text body of this
manual.
These safety warnings cannot eliminate the hazards that they
indicate. Common sense and strict compliance with the special
instructions while performing the action or service are essential to
preventing accidents.
Four commonly used safety symbols accompany the DANGER ,
WARNING and CAUTION blocks. The type of information each
indicates is as follows:
‹
This symbol points out important safety information that, if
not followed, could endanger personal safety and/or property
of others.
$
This symbol points out potential explosion hazard.
!
This symbol points out potential fire hazard.
+
This symbol points out potential electrical shock hazard.
The operator is responsible for proper and safe use of the equipment.
The manufacturer strongly recommends that the operator read this
Owner’s Manual and thoroughly understand all instructions before
using this equipment. The manufacturer also strongly recommends
instructing other users to properly start and operate the unit. This
prepares them if they need to operate the equipment in an emergency.
RULES FOR SAFE OPERATION
Study these RULES FOR SAFE OPERATION carefully before operat-
ing or servicing this equipment. Become familiar with the OWNER’S
MANUAL and with the engine. The engine can operate safely, effi-
ciently and reliably only if it is properly operated and maintained.
Many accidents are caused by failing to follow simple and funda-
mental rules or precautions.
The manufacturer cannot anticipate every possible circumstance that
might involve a hazard. The warnings in this manual and on tags and
decals affixed to the equipment, are therefore, not all-inclusive. If
using a procedure, work method or operating technique the manu-
facturer does not specifically recommend, ensure that it is safe for
others. Also make sure the procedure, work method or operating
technique utilized does not render the engine to be unsafe.
‹
DO NOT tamper with the engine governed speed.
High operating speeds are dangerous and increase
the risk of personal injury or damage to the equip-
ment. Operating at low speeds with heavy load may
shorten the engine’s life.
BEFORE OPERATING
• Gasoline is highly FLAMMABLE and its vapors are EXPLOSIVE. Do
not permit smoking, open flames, sparks or heat in the area while
handling gasoline. Avoid spilling gasoline on a hot engine. Comply
with all of the laws regulating storage and handling of gasoline.
• Store gasoline and other fuels only in containers designed and
approved for the storage of such materials.
• Pressure can build up in the fuel tank. Loosen the fuel cap slowly
to relieve any pressure in the tank.
• Add gasoline and other fuels in a clean, well-ventilated area. Wipe
up any spilled gasoline immediately. If gasoline has been spilled,
let it dry completely before starting the engine.
• Do not overfill the fuel tank. Always allow room for fuel expansion.
If the tank is overfilled, the fuel can overflow onto a hot engine
and cause a FIRE or an EXPLOSION.
• Thoroughly inspect the engine for loose or damaged parts before
each use. Do not use the engine until adjustments or repairs are
made.
• Check the oil level in the engine before each use.
• Inspect the engine periodically. Repair or replace all damaged or
defective parts immediately.
• Inspect fuel system frequently for leaks or damage. Repair or
replace any damaged or leaking component immediately. Never
attempt to change, alter or modify the engine fuel system in any
way that might affect safety or compliance with applicable codes
and standards.
