ROUTINE MAINTENANCE
Routinely check the condition, clean, tighten, repair, or replace as necessary the following:
• Muffler guard
• Hydraulic hoses and fittings
• Fuel lines
• Fasteners
• Safety decals
Barreto recommends using genuine Barreto spare parts to ensure not only quality but also the health
and safety of the operator.
Clean safety decals often using soap and water.
Do not use
abrasive cleaners or solvents such as
mineral spirits that may damage the decals. Replace any damaged (unreadable) or missing decals. If
you replace a machine part that has one or more decals affixed to it, replace the decals also.
Replacement parts and decals can be purchased from Barreto Manufacturing, Inc. When attaching
decals, the temperature of the mounting surface must be at least 40°F (5°C) and must be clean and
dry.
Service the engine according to the engine owner’s manual. Follow the directions for all aspects of
service including air filter change, oil level checking, filling, draining, disposal of engine oil, disposal
of petrol/gasoline, and off-season long-term storage.
Off-season long-term storage of the stump grinder can be at any ambient temperature.
