3) Adjustments & Maintenance
I) Service Safety

Wear gloves and eye protection and exercise care when handling blades as they are extremely sharp. Al-
so be alert to worn or damaged surfaces that could have sharp edges.

Disengage hydraulics, shut off engine and allow all movement to stop before leaving the operator’s posi-
tion to adjust, lubricate, clean or unclog the machine. Do not try to uncouple the hydraulic hoses unless
the pressure has adequately dissipated.

Before working on or underneath the machine, place blocks on both sides (front and back) of power
unit’s tires or treads and under each end of the attachment to prevent accidental lowering of the ma-
chine. Also, remove the ignition key from the power unit and allow all movement to stop before begin-
ning work.
II) Lubrication
The EX Series has 2 lubrication points, identifiable by the presence of a grease fitting. Use only Brush-
Hound approved grease or a compatible grease with similar specifications and EP additives (see “BrushHound
Recommended Greases” section in the appendix). Over-greasing seals and bearings can cause damage, if
grease purges from the bearing’s seals too much grease has been applied. If the purged grease is black and
smells burnt, it may be a sign of chronic over-greasing.
a) Idle Bearing
The idle bearing is located under the Idle Side Bearing Cover and has a grease fitting located on the
bearing’s mounting flange. The idle bearing comes pre-packed with high quality grease and its lubrication
schedule is dependent on running conditions. Under normal operation, 2-3 pumps of grease should be ap-
plied after every 40 hours of operation (or 1-2 months when usage is sporadic). If operating conditions are
abnormally wet, 2-3 pumps of grease should be applied daily.
b) Housed Drive Bearings
The motor side has a set of 2 angular contact bearings in a housing on the drive shaft with a grease
fitting located on the left motor cover. The housing comes pre-packed with high quality grease and requires
relatively infrequent greasing. Only 2-3 pumps of grease should be necessary every 3 months during normal
operation. If the motor is removed or the bearings changed, the housing should be repacked as follows:

50% fill inside bearing

100% fill in housing
III) Wearable Component Maintenance
a) Rubber Isolation Disk
Located between the drive side end plate and the bearing housing is a reinforced rubber isolation disk
that isolates the vibration of the drum and motor from the rest of the machine. The disk itself has a lifetime
of over 1000 hours, but should be inspected regularly for excessive wear. If the disk appears worn thin or
torn it should be replaced. It should also be replaced whenever the cutter drum is removed.
