The following safety instructions are provided to alert you to precautions which, if not followed,
may cause serious injury to yourself or others. Please read these instructions completely. Cross-
Tech Manufacturing can not cover every incident that might be a hazard. Extreme caution should
be used at all times. Only use Brush Wolf brush cutters for the purpose for which it has been
designed. Always operate an excavator/backhoe with a forestry rated door and cab.
Hearing protection must be worn at all times.
Site Inspection: Before operation of your Brush Wolf, carefully inspect the area to be cleared. Re-
move any items which may be picked up and thrown by the cutting blades; wire, pipes, or rocks.
Mark any object too large to move. This is an important step to help avoid damage to property, the
Brush Wolf brush cutter, your excavator/backhoe or personal injury. If an object is struck when op-
erating the Brush Wolf, immediately shut down power to both the attachment and the excavator/
backhoe. Any damage should be corrected and tested before continuation of cutting.
Equipment Inspection: Prior to inspection, disconnect the unit from the excavator/backhoe. To
inspect or to make repairs under the Brush Wolf cutter deck always block the unit securely in order
to prevent accidental release of the lift mechanism. Inspect all hydraulic hoses and shields to en-
sure they are in good condition and without holes before pressurizing. Hydraulic fluid can escape
under pressure and may cause serious injury or death. Wear safety goggles, ear protection, hard
hat, and only operate the excavator behind a shatter proof forestry rated door and cab.
Excavator / Backhoe Auxiliary Hydraulic Flow: Check the specifications of the Brush Wolf
models rated GPM to correctly match the hydraulic flow of your excavator/backhoe to ensure
proper operation.
Do Not operate near bystanders, vehicles, pets, livestock or buildings. Objects may discharge
while cutting with the Brush Wolf and has the potential to cause serious injury.
Do Not place hands, feet or other objects under the deck while the Brush Wolf is in operation. To
inspect or perform maintenance under the deck, always shut down the power to the Brush Wolf,
shut-off the excavator/backhoe engine, disconnect hydraulic hoses, and block the unit securely.
Do Not allow children to operate a rotary brush cutter. Only individuals with excavator/backhoe
experience who are well acquainted with the rules of safe operation should be allowed to operate
the Brush Wolf.
Do Not operate the Brush Wolf in conditions with poor visibility.
Safety Instructions

Safety Instructions
Do Not expose the underside of the blades towards the cab.
Do Not operate while intoxicated or if taking medications that may impair your senses or reac-
tions.
Do Not attempt to straighten blades. Order replacement blades if blades are bent,
cracked or damaged.
Do Not leave the Brush Wolf unattended while in a raised position. Always make sure both the
runners are placed firmly on the ground and shut down the excavator/backhoe.
Do Not continue operation if an unexpected object is struck. IMMEDIATELY shut down power
to both the attachment and the excavator/backhoe. Disconnect the hydraulic couplers from the
power source. Evaluate the damage, repair and the test unit before operation.
Do Not allow anyone or any item on top of the mower deck when in operation.
Make sure all hydraulic connections are tight and hoses and shields are in good
condition before applying pressure.
Hydraulic fluid escaping under pressure can penetrate skin and cause serious injury.
If this type of injury occurs, seek medical attention immediately.

Operation Instructions
1. Prior to operation check the blades and replace if cracked or damaged. All blades must be
replaced at the same time. Tighten the blade carrier to the blade bolts/nuts, and hydraulic
motor mount nuts. Check the hydraulic fluid. A low level could indicate a leak and require a
closer inspection of your unit.
2. Ensure pins or quick couplers are properly connected from the Brush Wolf to your excava-
tor/backhoe.
3. Verify the auxiliary hydraulic flow available at the stick of your excavator/backhoe is within
the range of the Brush Wolf rating of GPM - Gallons Per Minute.
4. Inspect the hydraulic couplers and wipe off water, dust or any debris. Dirt and debris can
damage hydraulic components. Once cleaned, connect the couplers from the cutter to the
auxiliary hydraulic system on the excavator/backhoe.
5. Connect the auxiliary hydraulic lines for the brush cutter to the excavator/backhoe. Twist
the collars of the quick connect couplers to secure the hydraulic connections.
6. Confirm all safety measures have been completed per the Safety Instructions. Most impor-
tantly make sure the area is clear of personnel and pets.
7. Enter shatter-proof cab door, engage seat belt, release brake and start engine. The runners
of the Brush Wolf should be as close to the ground as possible.
8. Slowly apply hydraulics to the Brush Wolf and increase the engine speed to high idle. Make
sure the unit is operating smoothly before moving the excavator/backhoe forward. When
temperatures are below zero allow additional time for hydraulic fluids to warm-up.
9. Maintain a speed to handle the volume of brush and to prevent stalling.
10. Stay alert for drop-offs, rocks, holes, abandoned wells and septic tanks. Do not operate or
drive across a steep embankment as this may cause a rollover and possible injuries or death.
11. To cut large diameter brush and trees, move forward slowly to make the cut.
12. When finished cutting, make sure the cutter is placed flat on the ground, throttle down the
excavator/backhoe and shut off the hydraulic flow to the unit, stop engine prior to leaving
the cab.
13. To disconnect hoses use proper hand protection as the couplers may be hot.

Maintenance
Your new Brush Wolf is a precisely engineered attachment and requires little maintenance.
The Brush Wolf is built to strict standards and will deliver years of dependable service by
following these maintenance guidelines:
1. Perform maintenance on level surface with the unit firmly on the ground and
blocked. Shut off the hydraulic power supply and disconnect hydraulic couplers.
Before operation, check the hydraulic hoses for any leaks.
2. Check all nuts and bolts for proper tightness. See Maintenance Schedule on page
8.
3. Every Brush Wolf is tested at the factory and all nuts and bolts have been tight-
ened to specifications. We recommend you check them after the first 4 to 6 hours
of operation and at regular intervals as defined in the Maintenance Schedule.
4. Tighten all the nuts which secure the blades to the blade carrier every eight (8)
hours. Torque the nuts to 775 ft - lbs with a 1-11/16” socket wrench. The nuts are
located under the access plate on the top of the blade carrier.
5. Inspect blades regularly to ensure they are sharp, tightened correctly and intact.
Blades must be replaced as a set and never try to weld or straighten damaged
blades, as loss of blade integrity will result.
6. Inspect hydraulic hoses daily or each use for damage, wear or leaks.
CAUTION: Always replace the entire set of blades. Never weld or
straighten damaged blades, as loss of blade integrity may result.
CAUTION: Replace missing or illegible safety decals immediately.
Decals are available at your Brush Wolf dealer.
CAUTION: Operator of excavator should be behind shatter-proof
glass.
