Fasteners

Replacement parts:
Replacement trencher parts and decals can be purchased from Barreto Manufacturing.
Replacement engine parts must be purchased from the engine manufacturer or dealer.
Decals:
Clean decals as necessary using soap and water. Replace damaged or missing decals. Remove damaged
decals using a heat gun. When ordering a part that has decals affixed to it, order the decals also. When
affixing decals, the mounting surface must be clean and above 40°F (5°C). To ease decal placement, fill a
spray bottle with water and add one drop of dish soap, lightly coat the mounting surface with a mist of the
soap-water, too much soap will ruin the decal adhesive. Place the decal on the surface and use a decal
squeegee to wipe out all soap-water and air bubbles. Alternatively, the mounting surface can be dry.
NOTICE:
•
Keep dig chain and undercarriage clean to prevent rust, excess wear, and maintain performance.
•
DO NOT
pressure wash or hose down bearings. Water will enter the bearing and dramatically
reduce bearing life. Wipe away grease, dirt and grime that accumulate on or near a bearing.
•
Solvents and abrasive cleaners will damage decals.
•
Service the engine according to the engine owner’s manual. Follow all directions for service and
safety.
•
Ethanol gasoline blends, common in the U.S., have a shelf life of about 90 days. Using expired
fuel will result in poor engine performance and introduce contaminants such as water into the
engine.
•
Engine – pump couplers must have a 1/16” gap. See exploded views assembly manual drawing
00572 & 00572-H13.
