HOT PARTS can cause severe burns.
• The exhaust system must be cold when servicing the spark arrestor.
Internal combustion engines operating in a highly com- bustible environment are a common fire hazard. Glow- ing carbon particles blown out with the exhaust can re- tain sufficient heat to ignite materials. While no practical spark arresting device will stop all sparks, this device will minimize fire hazards by removing and trapping most solid particles provided that is is properly maintained.
Inspect and service spark arrestor every 250 operation hours.
Clean spark arrestor in a noncombustible environment.
• Stop engine before cleaning spark arrestor.
•
Exhaust spark arrestor must be installed in accordance with local, state, and federal regulations.
ENGINE EXHAUST SPARKS can cause fire.
•
No indicator is provided to show the amount of ether left in the cylinder; therefore, it is recommended that a spare cylinder be kept on hand. Generally, the ether cylinder is empty if the engine fails to start in cold weather while uti- lizing the cold weather starting system.
WARNING: IMPROPER HANDLING OR EX- POSURE TO ETHER can seriously harm
your health.
• Follow the manufacturer’s safety instructions on the cylinder when handling ether compo- nents.
The cylinder can be weighed to determine the amount of ether inside. The cylinder weighs 33 ounces (936 gr) when full, and it weighs 15 ounces (425 gr) when empty. To replace the ether cylinder, see Section 4-10.
IMPORTANT: Before installing the ether cylinder, clean nozzle on ether cylinder and fitting into which the ether cylinder is inserted. If dirt is present in either of these ar- eas, the system may not work.
IMPORTANT: After installing or replacing ether cylin- der, do not use or test ether start system for at least 10 to 15 minutes to allow particles in fuel to settle to prevent atomizer plugging.

WARNING: ELECTRIC SHOCK can kill.
• Do not touch live electrical parts.
• Stop engine and disconnect negative (−) battery cable from battery before beginning this installation.
MOVING PARTS can cause severe injury.
• Keep away from moving parts such as fans, belts, and rotors.

5.When the weld/power speed reaches 1860 rpm, prevent the adjustment screw from turning, and tighten the securing nut.

6.Stop engine.

7.Close and secure side door.

WARNING: ELECTRIC SHOCK can kill

• Do not touch live electrical parts.

•Stop engine, and disconnect negative (−) bat- tery cable from battery before inspecting, maintaining, or servicing.

MOVING PARTS can cause serious injury.

•Keep away from moving parts such as fans, belts, and rotors.

HOT ENGINE PARTS can cause severe burns.

•Wear protective gloves and clothing when working on a hot engine.

Brush life is very good under most operating conditions. The brushes and slip rings should be inspected every six months or whenever excitation voltage is lost. Be sure that slip rings are clean and brushes are free to move. If the welding generator has been operating un- der extremely dusty or dirty conditions, increase the fre- quency of inspection.

Under normal use, the slip rings will discolor to a dark brown. If a buildup of brush material is noted, it may be necessary to clean the slip rings. Clean rings with a number 220 or finer sandpaper, and polish rings with crocus cloth. Never use emery cloth because part of the emery will embed itself into the rings and, in turn, de- stroy the carbon brushes.

Replace the brushes if they become chipped or broken or if less than 1/2 in. (12.7 mm) of brush material is left.

8-10. ETHER STARTING AID (Optional)

CAUTION: ETHER INJECTION WHILE ENGINE IS RUNNING can cause engine damage.

•Do not actuate ETHER STARTING AID while engine is running.

The ether used in the cold weather starting aid system is contained in a replaceable cylinder located behind the right rear side door on the center portion of the frame.
