OPERATOR PREPARATION
Each operator must:
• Become familiar with the controls and operation of the stump grinder, preferably under the supervision
of an experienced operator.
• Be at least 18 yrs. of age and be mentally and physically capable of operating the stump grinder safely.
• Have studied the SAFETY AND OPERATING INSTRUCTIONS in this manual.
PERSONAL PROTECTION: For safety, stump grinder operator should wear personal protection
equipment. Keep observers at a safe distance and do not operate if people are near, especially children and
pets.
Wear a face safety shield and hard hat while operating or
observing!
WARNING: The cutter wheel may throw wood chips,
stones and debris.
Wear safety boots and gloves. Wear close-fitting clothing.
Contain long hair. Do not wear jewelry. Wear reflective clothing
if working near traffic.
Wearing adequate hearing (ear) protection while operating or
observing is recommended.
WARNING: Exposure to loud noise is cumulative
Hearing protection devices do not all provide the same level of
protection. Those that completely surround each ear are better
than earplugs. It is important to select a device that is adequate and appropriate for your specific work
environment since the peak noise level varies. A local environmental noise specialist may help you to
determine the level of hearing protection required.

VIBRATION EMISSION DATA
Declared vibration emission value in accordance with EN 12096: the average measured vibration emission
value is 2.0 m/s². The uncertainty in the measurement is 2.4 m/s². Safety gloves help to isolate the hands
from the vibration, keep them warm and dry, maintain blood circulation, and make operators less
susceptible to vibration induced injury.
The Barreto Stump Grinder, Model E30SG when operated in accordance with its instructions, and tested in
accordance with EN 1033:1995, results in the following vibration emission declared in accordance with EN
12096:1996.
Average measured vibration emission value
ahv
2.0
m/s2
Uncertainty
K
2.4
m/s2
These values are suitable for comparison with the vibration emission levels of other tools that have been
obtained using the same test method.
Note: these figures represent the average value over 5 tests, with the figures in the x, y, and z axes
combined in a vector sum (ahv =
ahwx2 + ahwy2 + ahwz2). It is this sum that is averaged over all tests.
Since the value stated above is an average of several tests, and is based on data from all three exes, we
consider it to be a reasonable approximation of the true value, particularly considering the uncertainty in
the results (K).
This machine is unlikely to cause hand-arm vibration syndrome, as the average emission level is
equal to or less than 2.5 m/s²

DETERMINE LOCATION OF UNDERGROUND UTILITIES
OSHA CFR 29 1926.651 requires that the estimated location of underground utilities be determined before
beginning excavation or an underground drilling operation. When the actual excavation or bore approaches
an estimated utility location, the exact location of the underground installation must be determined by a
safe, acceptable and dependable method. If any utility cannot be precisely located, the appropriate utility
company must shut it off.
Call before you cut. If you do not call, you may cause an accident; suffer injuries or death; cause
interruption of services; damage the environment; and/or incur project delays. Expect to be held liable for
any damages caused, if you fail to call.
DANGER: Buried electric cables or gas lines can cause serious injury or death if struck with cutter
wheel. Always determine location of utilities before operating the machine.
WARNING: Fiber optic cables convey laser light that can injure your eyesight.
To locate utilities before beginning your grinding project, call 811 or 1-888-258-0808 (US. or Canada).
This free service will provide a “One-Call” number for the geographic area that you select. Before you start
any cutting project, be sure to call the local One-Call system in your area and any utility company that does
not subscribe to the One-Call system. The One-Call representative will notify participating utility
companies of your proposed cutting activities. Utilities will then mark their underground facilities by using
the following international marking codes:
Red
Electric
Yellow
Gas, oil, or petroleum
Orange
Communication, telephone, television
Blue
Potable water
Green/brown Sewer
White
Proposed excavation
Pink

WORK SITE ASSESSMENT
Examine the work area for any conditions or obstructions that may inhibit cutting or create a safety hazard
for the operator or others. Use the information in this manual combined with good judgment to identify any
hazards to avoid.
In addition to calling to DETERMINE LOCATION OF UNDERGROUND UTILITIES (see previous
section for details) the operator and/or job foreman should visually inspect the work site. Look for electrical
drop boxes; notices of underground placements; manhole covers; recent cutting activity; any evidence of
possible underground placements; banks; overhangs; drop-offs; rocks; tree limbs; wire; uneven terrain; any
existing trenches or holes; and toxic ground conditions.
Only operate stump grinder outdoors and avoid breathing engine exhaust and fumes.
WARNING: Engine exhaust contains carbon monoxide gas that is toxic. Breathing it can cause
unconsciousness and death.
Do not operate stump grinder near any source of flammable dust or vapors.
WARNING: Sparks from the engine exhaust can cause an explosion or fire in a flammable or
explosive atmosphere. Fuel fumes can catch fire or explode.
Allow adequate side and overhead clearances between stump grinder and any objects such as buildings,
fences, and trees.
Adequate lighting is required, daylight or artificial, for safe operation of the stump grinder.

CONTACT WITH UNDERGROUND UTILITIES
After LOCATING UNDERGROUND UTILITIES and performing the WORK SITE ASSESSMENT,
accidental contact with a buried utility might still occur. If it does, stop and call 911 for help.
If you cut a wire or cable, assume that you do not know what kind it is. It may be electrical or any one of
several communication lines: telephone, television, or fiber optic. In any case, do not touch it or even look
at the ends of it. Stop cutting and call 911 for help. Do not cut any more until the appropriate utility
company has assessed the situation, taken appropriate action, and informed you that is safe to proceed.
If you strike a pipe, it could be gas, oil, petroleum, water, or sewer. In any case, stop cutting, shut off the
engine, and evacuate the area immediately. Call 911 for help.
Electrical wires or cables: If you think that you may have severed electrical wires, stop cutting and call 911
for help. Keep yourself and other people away from the area.
DANGER: An electric shock could kill you. Assume that any severed wire or cable is HOT with
voltage and do not touch it!
Gas lines: If you think that you may have struck a gas line, shut off the engine and evacuate the area
immediately. Call 911 for help.
DANGER: A gas explosion could kill you. Sparks will likely occur from the cutter head scraping
the metal pipe. If gas leaks out an explosion could easily occur.
Fiber optic cables: If you think that you may have severed a fiber optic cable, do not touch or even look at
the ends of it.

STUMP GRINDING PROCEDURE
1. Raise the cutter head and move the machine into position to cut. Position the machine so the cut head
can swing across near the edge of the stump.
2. Have engine at full throttle (throttle lever forward).
3. Start cutter wheel.
4. Using the cutter head control lever, slowly swing the cutter wheel across the edge of the stump. Adjust
cut depth and swing speed to prevent the engine from bogging and to prevent cutter wheel stall.
5. After the swing is complete, move the cutter wheel down a few inches, and repeat the cutter wheel
swing.
6. Continue making a series of cuts down the edge of the stump until the edge is cut to below ground level
or the teeth are cutting at a depth below half the wheel radius.
7. Depending on the diameter of the stump it may be necessary to move the stump grinder. After cutting
the first edge move the machine forward and repeat the grinding procedure until the stump is
completely cut to below ground level.
GRINDING TIPS
Clear the work area of debris, branches and rocks.
Operate the cutter with engine at full throttle.
Listen to engine speed and watch cutter wheel speed. Adjust swing speed and cut depth to maintain high
engine and cutter speed. Avoid bogging the engine and stalling cutter wheel.
It is more efficient to cut the edge of the stump, rather than cutting a wide area. Once the teeth are cutting at
a depth below half the wheel radius, lift the cutter and move the machine forward to begin cutting a new
edge.
SHUT DOWN PROCEDURE
1. Always leave machine parked on a level surface.
WARNING: Do not park on incline. Move the machine to a level
surface and set the parking brake located behind the left hand track
motor, near decal shown. Move the handle down to engage the brake.
2. Unless loaded on a trailer, lower the cutter head to the ground.
3. Reduce the ENGINE THROTTLE to idle.
4. Move the IGNITION KEYED SWITCH to the OFF position to stop the engine, and remove the key.
5. Close the FUEL SHUTOFF VALVE.
Shut off engine and allow it to cool before refueling.
WARNING: Fuel fumes can catch fire or explode. Do not smoke or allow flames or sparks in the
area.
Do not touch the engine, muffler, or any of the hydraulic components until
cool.
WARNING: Muffler and engine get hot enough to cause serious
burns. For the safety of yourself and others, allow enough time for the
engine, muffler, and the hydraulic fluid to cool completely before performing
any cleaning or maintenance.

TRACK CONTROL: Controls the travel direction and speed.
• Track controls are designed to be operated with two hands.
• Pushing the control handles forward from neutral position causes the machine to move forward.
• Pulling the control handles back from neutral position causes the machine to move backward.
• Moving the track control handles farther from the neutral position increases the speed.
• Steer the machine by moving one track control handle farther than the other handle. This causes the
track on one side to rotate at a different speed than the opposite track. Pivot turns can be made by
moving one control forward and the other control back.
Keep away from tracks to avoid being crushed.
WARNING: Being run over by the stump grinder will cause injury.
Never allow anybody to ride on the machine.
Never make sudden changes in speed or direction.
Use extra caution on soft or uneven ground.
Avoid operating adjacent to drop-offs or embankments.
Avoid inclines if at all possible. Never use on any incline exceeding the angles shown below.
WARNING: Navigating on any incline increases the danger of the machine losing traction or
rolling over, especially if the surface is wet. If you lose control get out of the way immediately to
avoid personal injury. Navigation on inclines should be especially slow and turns very gradual.
A 20° maximum incline is allowed.

EMERGENCY TOWING
In case of engine failure there is a provision that allows the machine to be towed a short distance.
The drive tracks are driven by a set of tandem pumps. The front pump drives right track, and the other
pump drives left track. The drive pump by-pass valves located on the side of the pump may be opened to
allow the machine to be towed.
•
•
•
Set the parking brake if on a slope to prevent rolling. It is located behind the left hand track motor.
Move the handle down to engage the brake.
WARNING: Navigating on any slope increases the danger of the machine losing traction or rolling
over, especially if the surface is wet. Stay out of the way to avoid personal injury.
Loosen (do not remove) the by-pass plugs two complete turns counterclockwise, see bottom drawing.
Loosen both cartridges in the counter balance valve on each track drive motor, see below.
Counter balance valve
cartridges.
•
•
•
•
If loosening cartridges does not work, disconnect hydraulic hoses to motor.
Disengage the parking brake by moving the handle up.
The machine may be towed short distance (1/8 mile or 1/4km) at slow speed, 2 mph or 200 feet per
minute maximum (3kph or 60m per min).
After towing, close both by-pass valves by closing the plugs with 10 foot-pounds torque.
Use a trailer or truck for road transport.
If you need to raise the cutter head without power, do the following:
1. Use straps or chains to support the cutter head.
2. Loosen the hose at the back port of the lift cylinder and raise the cutter head end with a hoist or forklift
if available.
3. If it still will not lift, then also loosen the hose at the front port of the lift cylinder.
WARNING: The cutter head is heavy. Manpower alone is not recommended, but if necessary, use a
team of two strong workers to raise the head, and a third worker to tighten the hose(s) after the head
is up.
4. Secure the head in the up position with a strap or chain on the cut head housing.

ROAD TRANSPORT OF THE STUMP GRINDER
The BEST way to transport the stump grinder over roads is with the BARRETO E4X6 TILT BED
TRAILER.
Refer to the following checklist before towing:
• Towing vehicle should have a 2" (5cm) ball. Be sure it is in good repair and securely fastened to the
vehicle.
• Securely fasten the hitch to the ball by tightening the hitch nut.
• Cross the chains under the trailer tongue to prevent the tongue from dropping to the ground if the trailer
comes loose.
• Allow only enough slack in the chains to permit proper turning of the vehicle. Do not let the chains
drag on the ground or be drawn up too tight. Slack strength should hold the tongue and coupler off the
ground with the trailer loose.
• Attach the safety chain to the towing vehicle in such a way that it cannot come off accidentally.
• Check the hitch-to-ball connection after driving a few blocks and re-tighten if necessary.
Always exercise extreme caution and allow extra clearance while towing a trailer. DRIVE SAFELY!
LOADING PROCEDURE of the stump grinder onto the Barreto E4X6 tilt bed trailer:
1. Position the tow vehicle and attached trailer on level ground.
2. Unlatch the trailer tilt bed latch pin to tip up the trailer bed. Leave the latch pin where the spring-loaded
action will engage the pin with the latch when the bed is leveled again.
3. Line up the stump grinder with the rear of the trailer. The cut head should be toward the trailer.
4. Drive the stump grinder slowly forward onto the trailer bed. As the weight of the stump grinder reaches
the balance point the bed will level itself.
WARNING: Navigating on the inclined trailer bed increases the danger of the tracks losing traction,
especially if the bed surface is wet. Stay out of the way to avoid personal injury if you lose control.
5. The chains of the 00340 TIE-DOWN KIT are long enough to adjust for
desired trailer tongue weight.
6. Loop front chain through D-ring on front of stump grinder and into
keyhole slot in mount.
7. Back up stump grinder until front chain is tight.
8. Throttle down and shut off the engine, then close the fuel shutoff valve.
Refer to the SHUT DOWN PROCEDURE for details.
9. Loop rear chain through chain loops on rear of stump grinder and Drings on trailer.
10. Hook to ratchet load binder and tighten.
The quick link is provided to prevent losing the chain when not in use. Attach it between chain links next to
one of the trailer D-rings. Never apply the tie-down load to it.
Check that the trailer tilt bed latch pin is engaged with the latch.
UNLOADING PROCEDURE of the stump grinder from the Barreto E4X6 tilt bed trailer:
1. Position the tow vehicle and attached trailer on level ground.
2. Remove all chains or straps connecting the stump grinder to the trailer D-rings
3. Start the engine using the ENGINE START UP PROCEDURE.
4. Unlatch the trailer tilt bed latch pin and rotate the latch pin handle to lock it open.
5. Drive the stump grinder slowly backward. As the weight of the stump grinder reaches the balance point
the trailer bed will tilt up. Continue backward until tracks are completely on the ground.

LOADING PROCEDURE of the stump grinder onto a truck bed using a hoist:
Never attempt to hoist the stump grinder unless suitable equipment is available to
lift and lower machine onto the truck. If using a sling, the minimum required
working load limit per sling leg is 1000 lb (450 kg). Minimum sling leg length is 6
ft (2 m).
1. Position the truck and stump grinder on level ground.
2. Follow the stump grinder SHUT DOWN PROCEDURE.
3. Attach lifting sling legs around both rear tie down loops and around the chain
motor housing. Ensure machine weight is evenly distributed, then hoist onto the truck bed.
Never lift stump grinder over any person at any time.
WARNING: If stump grinder should fall it would crush anybody under it.
4. Chain or strap the stump grinder to the truck using the two chain loops at the rear of the stump grinder
lower body and D-ring on front of the stump grinder.
