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
purpose for which they have been designed. Always operate 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 the Alpha, 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.
Equipment Inspection: Prior to inspection the unit must be disconnected from the skid
steer. To inspect or to make repairs under the Alpha 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: The Alpha XP is only to be used on a skid steer
with auxiliary hydraulic flow rated at 30 - 45 GPM (Gallons Per Minute). Any less GPM and
the Alpha will not operate at peak proficiency.
The Alpha HD is to be used on a skid steer with auxiliary hydraulic flow rated at 23 - 29
GPM (Gallons Per Minute).
<IMPORTANT> SHUT DOWN: The piston motor is very quiet and shut down for
the blades to stop spinning takes over 2 minutes before the carrier stops. There-
fore for saftey - lower lift arms, make sure the cutter is placed flat on the ground, shut
off the switch for the auxiliary hydraulics, once hydraulics are shut off then slowly throttle
down the skid steer, stop the engine, and engage parking brake prior to leaving the cab.
Do Not operate within 300’ of bystanders, vehicles, pets, livestock or buildings. Objects may
discharge while cutting with the Alpha and has the potential to cause injury or death.
Do Not place hands, feet or other objects under the deck while the Brush Wolf Alpha is in
operation. 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.
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.

Operation Instructions
1. Prior to operation check blades and replace if cracked or damaged. All blades must be re-
placed at the same time. Tighten the blade carrier to the bearing housing, 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. Connect the Brush Wolf Alpha to your skid steer with the universal quick-tach mount.
3. Once connected, visually check the lock pins to make sure the Alpha is securely locked in
place. Do Not operate the Brush Wolf Alpha XP on Low Flow auxiliary hydraulic or any
skid steer rated under 30 GPM. All Alpha XP units are designed to operate on skid steers
rated with auxiliary hydraulic flow of 30 - 45 GPM. Alpha HD is rated for skid steers with
auxiliary hydraulics of 23 -29 GPM.
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 and case drain to the skid steer.
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 Alpha should be as close to the ground as possible.
8. Slowly apply hydraulics to the Brush Wolf Alpha and increase the engine speed to high idle.
Make sure the unit is operating smoothly before moving the skid steer forward. When tem-
peratures 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 with possible injuries or
death.
11. To cut large diameter brush and trees, move forward slowly to make the cut.
12. <IMPORTANT> SHUT DOWN: The piston motor is very quiet and shut down
for the blades to stop spinning takes over 2 minutes before the carrier stops.
Therefore for saftey - lower lift arms, make sure the cutter is placed flat on the ground,
shut off the switch for the auxiliary hydraulics, once hydraulics are shut off then slowly
throttle down the skid steer, stop the engine, and engage parking brake prior to leaving the
cab.
13. To disconnect hoses use proper hand protection as the couplers may be hot.

Maintenance
Your new Alpha Brush Wolf is a precisely engineered attachment and requires little maintenance.
Your 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. Shut off the
hydraulic power supply and disconnect hydraulic couplers.
2. Check all nuts and bolts for proper tightness. See Maintenance Schedule.
3. Every Brush Wolf is tested at the factory and all nuts and bolts have been tightened 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. Inspect blades for damage before each use. Tighten all the nuts which secure the blades
to the blade carrier every eight (8 )hours. Torque to 775 ft - lbs with a 1-11/16” socket on
the Drop (3) Blade Carrier. Torque to 275 ft - lbs with a 1-1/8” on the Flat (4) Blade
Carrier. The nuts are located under the access plate on the top of the blade carrier. (see
Parts Diagram on Page 12 item # 5).
5. Tighten the nuts on the blade carrier at the lower end of the bearing housing. Torque to
380 ft - lbs with a 15/16” socket wrench.
6. Check lubricant level weekly. Remove the bearing housing plug to check level. Loss of
fluid could be indicative of a leak. When adding oil use 80 W 90 gear lube weight.
Oil Port
CAUTION: Always replace the entire set of blades. Never weld or
straighten damaged blades, as loss of blade integrity may result.
