STUMP GRINDER INSTRUCTIONS UPON DELIVERY
Upon delivery, check for freight damage and any missing items. If there is damage, notify the carrier
and Barreto Manufacturing immediately and make sure to document there was damage on the
delivery receipt. Please take pictures of any damage immediately if possible before unpacking crate.
Remove machine from shipping crate.
When documentation refers to “right side” or “left side”, it is relative to the operator’s position with
both hands on the controls.
SERVICE INFORMATION
BELT SYSTEM:
Your stump grinder arrives with a heavy duty belt drive system. This system will need periodical
inspection and service.
BRAKE SYSTEM:
Your stump grinder has a cable-operated parking brake system which may need to be adjusted as the
cables stretch with use.
NOTE: It is very important to move the fuel shutoff lever to the closed position after stopping
the engine. Failure to do so could cause fuel to leak down into the cylinder and crankcase.
Damage resulting from this will void your engine warranty and not be covered.
IMPORTANT - The engine on the Barreto stump grinder 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. Service the engine according to the engine
owner’s manual before starting.
NOTE: We recommend that the cutter teeth be tightened to 25 ft. lbs. after every use.

HOUR METER
The DGI®TACH/HOUR hour meter tracks the hours of machine operation in order for routine
maintenance to be performed on a timely basis.
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.
Refer to this manual for equipment service requirements and to the Engine Manual for other
engine service requirements.
While Flash Alert is active, hold the tip of the RESET TOOL (Key Kancel Wand) against the
meter as shown. Within several seconds, the display will stop flashing indicating the Service
Interval has been reset. If the wand gets lost, a small mechanic’s pick-up magnet will work.

follow the SHUT DOWN PROCEDURE in the OPERATOR’S MANUAL.
Do not touch the engine, muffler, or any of the belt components until cool.

ROUTINE MAINTENANCE
Routinely check the condition, clean, tighten, repair, or replace as necessary the following:
•Muffler Guard
•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.

BRIGGS/VANGUARD MAINTENANCE SCHEDULE
Please see your engine owner’s manual for specific procedures and products to use for proper
maintenance of your engine, as well as proper disposal of used parts/fluids.

13SGH-16SGB OWNER’S MANUAL 8/29/18 Page 9 of 11
CUTTER WHEEL TORQUE SPECS
We recommend that the teeth and holders be inspected after every use to maximize the usable
life of these high wear items.
•Cutter teeth have three sides and we recommend rotating them frequently to keep the cutting
edges sharp. A torque wrench should be used to torque these down to 25 ft. lbs. A worn and
unsharpened tooth will cause the holders to wear prematurely, resulting in poorer performance
and increased maintenance costs.
•The holders should be inspected and torqued to 180 ft. lbs. using a torque wrench as well.
•The nuts that fasten the axle and drive stubs on the cutter wheel together should be torqued to
55 ft. lbs. using a torque wrench.
