Maintenance
Your new Brush Wolf 72 M-AX Exteme Duty is a precisely engineered attachment and re-
quires little maintenance. The Brush Wolf 72 M-AX 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 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. Inspect blades and the pins to the blade bolts before each use. Tighten all the
nuts which secure the blades to the blade carrier every eight (8 )hours. Torque to
540 ft - lbs with a 1-11/16” socket on the
Drop (3) Blade Carrier.
Torque to 270
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 cutter (see Parts Diagram on Page 12 item # 2).
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 plugs. If the resevoir
is full it will measure within 2” of the plug cap. Loss of fluid could be indicative of
a leak. When adding oil use 80 W 90 gear lube weight -
DO NOT
over fill - too
much lubricant will rupture the bearing housing. The bearing housing is full
when the oil level is 2” from the plug cap.
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 72 M-AX dealer.
