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.
