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.

LIFTING

The POWER-ARC 4000 should be lifted by two peo- ple. (It weighs 160 lbs/72.5 kg.) Its welded tube roll cage is designed to make lifting easy.

ANGLE OF OPERATION

Internal combustion engines are designed to run in a level condition to achieve optimum performance. The maximum angle of operation for the engine is 15 degrees from horizontal in any direction. Be certain to place the machine on a firm, non-skid, structural supporting surface. Anchor unit if necessary.

If you are operating the engine at a slight angle, be certain to check the oil regularly and maintain a level, full oil condition. The effective fuel capacity will also be slightly less than the specified 1.00 gallon (3.8 liters).

PRE-OPERATION ENGINE SERVICE

Read and understand the information about the gaso- line engine in the OPERATION and MAINTENANCE sections of this manual and the engine owner’s man- ual 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 with the Briggs and Stratton 8 HP engine produced after August 1998 and the Power-Arc 4000 with the Honda 9 HP engine are sup- plied with low oil shutdown protection. The Power- Arc 4000 with the Briggs and Stratton 8 HP engine produced before August 1998 is NOT equipped with an "Oil Gard"® low oil shutdown protection device. Oil must be regularly checked and added as needed. However, the engine block is equipped to accept an "Oil Gard"® accessory kit available from authorized Briggs and Stratton Distributors. An installed kit will sense low oil levels and will automatically shut down the engine. The engine cannot be restarted until suffi- cient oil is added.

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. Change oil after the first 5 hours of operation.

For more oil fill and service information, see the Engine owner’s manual.

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 fuel tank mounted on the engine. See the engine owner’s manual for more details about fuel.
