STACKING

POWER-ARC 4000 machines CANNOT be stacked.

TILTING

Place the machine on a secure, level surface whenev- er you use it or store it. Any surfaces you place it on other than the ground must be firm, non-skid, and structurally sound.

The gasoline engine is designed to run in a level posi- tion for best performance. It can operate at an angle, but this should never be more than 15 degrees in any direction. If you do operate it at a slight angle, be sure to check the oil regularly and keep the oil level full. Also, fuel capacity will be a little less at an angle.

FUEL

Fill the fuel tank with clean, fresh, regular grade lead-free gasoline. DO NOT MIX

OIL WITH THE GASOLINE.

The POWER-ARC 4000 has a plastic, 1.00 gallon (3.8) fuel tank mounted on the engine. See the OPERATION and MAINTENANCE sections of this manual for more details about fuel.

MUFFLER DEFLECTOR

The POWER-ARC 4000 is shipped with an exhaust deflector. You can mount it yourself on the gasoline engine.

To install the deflector, do the following:

PRE-OPERATION ENGINE SERVICE

Read and understand the information about the gaso- line engine in the OPERATION and MAINTENANCE sections of this manual before you operate the POWER-ARC 4000.

WARNING

•Keep hands away from the engine muffler or HOT engine parts.

•Stop the engine when fueling.

•Do not smoke when fueling.

•Remove the fuel cap slowly to release pressure.

•Do not overfill the fuel tank.

•Wipe up spilled fuel and allow the fumes to clear before starting the engine.

•Keep sparks and flame away from the fuel tank.

OIL

The POWER-ARC 4000 is shipped with the engine filled with SAE 10W-30 oil.

CHECK THE OIL LEVEL BEFORE YOU START THE ENGINE. This is an added precaution. When full, the oil level should be at the top of the fill plug hole. If it is not full, add enough oil to fill it. Be sure the fill plug is tight.

For more oil fill and service information, see the MAIN- TENANCE section of this manual.

CAUTION

Never position the deflector upward. Moisture or debris can enter the engine and damage it. As a gen- eral safety practice, position the deflector to direct exhaust gases away from the operator’s face and eyes.

•Fasten the deflector onto the muffler with the screws provided.

NOTE: The deflector reduces generator output power up to 100 watts.

SPARK ARRESTER

Gasoline engine mufflers may emit sparks when the engine is running. Some federal, state, or local laws require spark arresters in locations where unarrested sparks could present a fire hazard.

Standard mufflers and deflectors (like the ones includ- ed with the POWER-ARC 4000) do not act as spark arresters. When local laws require it, a spark arrester must be installed on the machine and properly main- tained. An optional spark arrester kit is available for your POWER-ARC 4000. See the ACCESSORIES section of this manual for more information.

CAUTION

An incorrect spark arrester may lead to damage to the engine or reduce performance. A suitable spark arrester for the Briggs & Stratton 8 HP Cool Bore® engine is available as a Lincoln field-installed option.
