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
HYDRAULIC SYSTEM:
•
Your stump grinder should arrive with approximately 14 U.S. gallons (53 liters) of tractor
transmission / hydraulic fluid in the tank. Shipping regulations may prohibit shipping with the
hydraulic fluid. Check the reservoir level using the sight gauge on the side of the tank. If required,
add tractor transmission / hydraulic fluid to the reservoir. For machine use in ambient temperatures
b32°F (0°C) and +90°F (32°C) hydraulic fluid ISO 68 is recommended. If the machine is
operated at temperatures below +32°F (0°C) then hydraulic fluid ISO 46 is recommended.
•
Recheck oil level after stump grinder has been run and oil has circulated through the components.
Routinely check level thereafter.
•
Change hydraulic fluid filter after the first 50 hours of use. Change it every 200 hours thereafter.
•
Add approximately one quart (1 liter) of hydraulic fluid to reservoir with each filter change.
•
Discard the old filter according to environmental standards in your geographic area.
•
Check all hydraulic fittings for leaks and tighten if necessary.
WARNING - Running the stump grinder without hydraulic fluid will cause serious damage to the
hydraulic pump. INSURE THAT THE RESERVOIR FLUID LEVEL IS VISIBLE IN THE SIGHT
GAUGE BEFORE STARTING THE MACHINE.
***
IMPORTANT:
If the couplers between the engine and the cutter head pump
are moved or removed for any reason, it is CRITICAL that they have a 1/16
th
inch gap between them when reinstalled. Failure to have this gap will result in
rapid wear and failure of your pump!
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.
