GENERAL INFORMATION

■

Some illustrations in this manual show the

stump grinder with safety shields removed to pro-

vide a better view. The stump grinder should never

be operated with any safety shielding removed.

The purpose of this manual is to assist you in operating

and maintaining your stump grinder. Read it carefully. It

furnishes information and instructions that will help you

achieve years of dependable performance. These

instructions have been compiled from extensive field

experience and engineering data. Some information

may be general in nature due to unknown and varying

operating conditions. However, through experience

and these instructions, you should be able to develop

procedures suitable to your particular situation.

The illustrations and data used in this manual were cur-

rent at the time of printing, but due to possible inline

production changes, your stump grinder may vary

slightly in detail. We reserve the right to redesign and

change the stump grinders as may be necessary with-

out notification.

Throughout this manual, references are made to right

and left directions. These are determined by standing

behind the equipment facing the direction of forward

travel. Cutting wheel rotation is clockwise as viewed

from the left of the stump grinder.

(Safety Rules continued on next page)

Safety is a primary concern in the design and

manufacture of our products. Unfortunately, our

efforts to provide safe equipment can be wiped

out by an operator’s single careless act.

In addition to the design and configuration of

equipment, hazard control and accident preven-

tion are dependent upon the awareness, con-

cern, judgement, and proper training of

personnel involved in the operation, transport,

maintenance, and storage of equipment.

It has been said, “The best safety device is an

informed, careful operator.” We ask you to be

that kind of operator.
