Recommended Brands of Hydraulic Oil:

As of November 10 of 2002, Alamo Industrial ™ changed the specification in regard to the recommended hydraulic oil for use in the current Machete Boom and Brahma mounted mowing system. This Oil change effects the front mounted 18-gallon oil tank, front mounted pump and motor circuit of the Machete Boom.

This update to the specifications will better protect against the possibility of internal motor wear and loss of power.

To comply with the new specifications, the front tank hydraulic oil should be changed to the recommended ISO rated AW 100 hydraulic Oil (Alamo Industrial Part No. 00751758)

One of the following equivalents can be used as they are equal to the Alamo Industrial ™ recommended hydraulic Oil.

TEXACO:	Texaco Rando ® HDZ ISO 100
CHEVRON:	Chevron Machine Oil AW ISO 100
SHELL:	Shell TELLUS ® Plus Oil ISO 100
PENNZ:	PENNZBELL ® AW Hydraulic Oil ISO 100
