IMPORTANT SAFETY INSTRUCTIONS

Air-cooled 7 kW, 12 kW and 15 kW Generators

SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe

operation be copied and posted near the unit’s installation site. Safety should be stressed to all operators and potential operators of this equipment.

WARNING:

The engine exhaust from this product contains chemicals known to the state

of California to cause cancer, birth defects or other reproductive harm.

WARNING:

 

This product contains or emits chemicals

 

 

known to the state of California to cause

 

cancer, birth defects or other reproductive harm.

Study these SAFETY RULES carefully before install- ing, operating or servicing this equipment. Become familiar with this Owner’s Manual and with the unit. The generator can operate safely, efficiently and reliably only if it is properly installed, operated and maintained. Many accidents are caused by failing to follow simple and fundamental rules or precautions.

The manufacturer cannot anticipate every possible circumstance that might involve a hazard. The warn- ings in this manual, and on tags and decals affixed to the unit are, therefore, not all-inclusive. If using a procedure, work method or operating technique the manufacture does not specifically recommend, ensure that it is safe for others. Also make sure the procedure, work method or operating technique uti- lized does not render the generator unsafe.

 WARNING: This product contains or emits chemicals DANGER

Despite the safe design of this generator, operating this equipment imprudently, neglecting its maintenance or being careless can cause possible injury or death. Permit only responsible and capable persons to operate or maintain this equipment.

Potentially lethal voltages are generated by these machines. Ensure all steps are taken to render the machine safe before attempting to work on the generator.

Parts of the generator are rotating and/or hot during operation. Exercise care near running generators.

GENERAL HAZARDS

For safety reasons, the manufacturer recommends that the installation, initial start-up and main- tenance of this equipment is carried out by an Authorized Dealer.

The engine exhaust fumes contain carbon monox- ide, which can be DEADLY. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. This exhaust system must be installed properly, in strict com- pliance with applicable codes and standards. Following installation, do nothing that might ren- der the system unsafe or in noncompliance with such codes and standards.

Keep hands, feet, clothing, etc., away from drive belts, fans, and other moving or hot parts. Never remove any drive belt or fan guard while the unit is operating.

Adequate, unobstructed flow of cooling and venti- lating air is critical to correct generator operation. Do not alter the installation or permit even partial blockage of ventilation provisions, as this can seri- ously affect safe operation of the generator. The generator MUST be installed outdoors.

When working on this equipment, remain alert at all times. Never work on the equipment when physically or mentally fatigued.

Inspect the generator regularly, and contact the nearest Authorized Dealer for parts needing repair or replacement.

Before performing any maintenance on the gen- erator, disconnect its battery cables to prevent accidental start up. Disconnect the cable from the battery post indicated by a NEGATIVE, NEG or (–) first. Reconnect that cable last.

Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and may result in dangerous operating con- ditions from leaking exhaust gases, fuel leakage, oil leakage, etc.
