STACKING

Bulldog® 140 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.

OIL

The Bulldog® 140 is shipped with the engine filled with SAE 10W30 oil. CHECK THE OIL LEVEL BEFORE YOU START THE ENGINE. This is an added precau- tion. Do not screw in dipstick when checking oil level. DO NOT OVERFILL. Be sure the fill plug is tight after servicing.

FUEL

Fill the fuel tank with clean, fresh, regular grade (mini- mum 87 octane lead free gasoline. DO NOT MIX OIL WITH GAS. The Bulldog® 140 capacity is approxi- mately 6.8 gallons (25.74 Liter). DO NOT OVERFILL, allow room in the fuel tank for fuel expansion.
