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 com-
pletely. 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 pur-
pose for which it has been designed. Always operate a skid steer with a forestry rated door
and cab. Safety goggles and hearing protection must be worn at all times.
Site Inspection: Before operation of your Brush Wolf, carefully inspect the area to be
cleared. Remove 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 skid steer or personal injury. If an
object is struck when operating the Brush Wolf, immediately shut down power to both the
attachment and the skid steer. Any damage should be corrected and tested before continu-
ation of cutting.
Equipment Inspection: Prior to inspection, disconnect the unit from the skid steer. 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 ensure they are in good condition and without holes before pressurizing. Hydrau-
lic fluid can escape under pressure and may cause serious injury or death. Wear safety gog-
gles, ear protection, hard hat, and only operate the skid steer behind shatter proof forestry
rated door and cab.
Skid Steer Auxiliary Hydraulic Flow: Check the specifications of the Brush Wolf models
rated GPM to correctly match the hydraulic flow of your skid steer to ensure proper opera-
tion.
Do Not operate near bystanders, vehicles, pets, livestock or buildings. Objects may dis-
charge 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 oper-
ation. To inspect or perform maintenance under the deck, always shut down the power to
the Brush Wolf, shut-off the skid steer engine, disconnect hydraulic hoses, and block the
unit securely.
Do Not raise the mower deck when blades are rotating. Operation with the mower raised
will expose the cutting blades and the potential for injury or death.
Do Not allow children to operate a rotary brush cutter. Only individuals with skid steer
experience who are well acquainted with the rules of safe operation should be allowed to
operate the Brush Wolf.
Safety Instructions

Safety Instructions
Do Not operate the Brush Wolf in conditions with poor visibility.
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 skid steer.
Do Not continue operation if an unexpected object is struck. IMMEDIATELY shut down pow-
er to both the attachment and the skid steer. 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.
Do Not operate until all of the members of your work crew are alerted to the dangers of walking
up to the brush cutter while 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 gearbox, blade bolts/nuts, and
hydraulic motor mount nuts to torque specification on Page 10. Check the hydraulic fluid.
A low level could indicate a leak and require a closer inspection of your unit.
2. Connect the Brush Wolf to your skid steer with the universal quick-tach mount.
3. Once connected, visually check the lock pins to make sure the Brush Wolf is securely locked
in place. Raise the Brush Wolf to 12” above ground level. Loop the lift limit chain through
the chain ring on your skid steer and back to the chain bracket on your Brush Wolf. Verify
the hydraulic flow of your skid steer 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 skid steer.
5. Connect the auxiliary hydraulic lines for the brush cutter to the skid steer. If you have a High
Flow skid steer and brush cutter - attach the case drain to the skid steer. Twist the collars of
the quick connect couplers to secure the hydraulic connections. Do not operate the brush
cutter on High Flow hydraulics (over 30 GPM) unless the brush cutter is equipped with a
High Flow motor this may cause damage to the motor and void the warranty.
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. Never raise the Brush Wolf
more than seven (7) inches off the ground while in operation.
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 skid steer forward. When tempatures
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, lower lift arms, make sure the cutter is placed flat on the ground,
throttle down the skid steer and shut off the hydraulic flow to the unit, stop engine, and
engage parking brake prior to leaving the cab. Noise at shut down is normal.
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:
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 gearbox for proper lubricant and hydraulic hoses for
any leaks. To check lubricant level, remove pipe plug from the side of the gearbox.
Lubricant should be the same level as the plug. See diagram on page 10.
IMPORTANT: Do not overfill, as too much lubricant may rupture the gearbox
seals.
1. Check all nuts and bolts for proper tightness. See Maintenance Schedule on page
10.
2. 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.
3. 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 cutter deck. Also, tighten the cas-
tle nut holding the blade or bar carrier to the output shaft of the gearbox, torque
to 450 ft - lbs with a 1-1/2” socket wrench.
4. 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.
5. Inspect hydraulic hoses daily or each use for damage, wear or leaks.
6. Shear bolt protection (also known as butter bolt) at the motor coupler. It is
recommended to carry additional shear bolts GRD 2 obtained at most hardware
stores. Only use grade 2 when replacing.
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.
