HYDRAULIC TRACK TRENCHER OWNER’S MANUAL CONGRATULATIONS! You are now the proud owner of the BARRETO trencher. The OPERATOR’S MANUAL is attached to the machine. Please study it and this manual to become familiar with the trencher, its characteristics, and method of operation. Pay particular attention to the safety and operating instructions to prevent personal injury or equipment damage.
Damage resulting from this will void your engine warranty and not be covered. IMPORTANT - The engine on the Barreto trencher may or may not have been serviced prior to shipping. Shipping regulations may prohibit shipping with fuel or oil in the engine. Check levels and add oil and fuel as required before starting engine.
Your DGI® hour meter is pre-set at the DGI® factory to go into Flash Alert mode at 25-hour intervals. Although the engine manufacturer does not require changing engine oil this often, due to heavy-duty use and extreme conditions inherent to tiller use, Barreto Manufacturing strongly recommends frequent oil changes.
LUBRICATION REQUIREMENTS Grease at the intervals indicated per the illustration of grease lubrication points. There is also a grease diagram decal on the machine. Page 5 of 22 1324TK - 1624TK OWNER’S MANUAL 12/4/14...
