WARNING
Prevent serious injury or death caused
by unexpected movement:
1�
Park on a level surface�
2�
Lower boom mower to ground�
3�
Engage parking brake�
4�
Shut off engine and remove key�
Pump grease into grease fittings located at all
pivot points and cylinder ends every month.
The rotor bearings are factory lubricated with a
lithium or lithium complex base grease which is
suitable for most applications. Select a grease
that is compatible with a lithium or lithium complex
grease.
The bearings should contain as much grease as
speed will permit. A full bearing with consequent
slight leakage through the seal is the best
protection against contaminant entry.
The following table is a general guide for normal
operating conditions. Extreme situations may
require a change in lubricating periods as dictated
by experience.
Generally, a lower quantity of grease at frequent
intervals is more effective than a greater quantity
at extended lubrication intervals.
Using the table below, the boom mowers operate
in the 1501-2000 rpm range. Determine the
lubrication interval based on the hours of use per
day. Typical lubrication quantity is 1 pump from a
standard grease gun.

In the higher speed ranges too much grease will
cause overheating. The amount of grease that
the bearing will take for a particular high speed
application can be determined only by experience.
If excess grease in the bearing caused overheating,
it will be necessary to remove grease fitting to
permit excess grease to escape.
