2.3 About This Manual
DANGER!
Safety instructions are important! Read all safety rules in this manual as well as all
safety rules in any related equipment manuals!
The purpose of this manual is to assist you in properly and
safely operating and maintaining the deck. Read and under-
stand this entire manual before attempting to set-up, operate,
adjust, perform any maintenance on, or store the deck. This
manual provides essential information and instructions which
will help you enjoy years of dependable performance from the
deck.
The designed and tested safety of the deck is dependent upon its operation within the
parameters and limitations explained in this manual. Be familiar with and follow all safety
rules in this manual as well as all safety rules for any related equipment.
Although these instructions have been compiled through extensive field experience and
engineering data, some information presented herein may be general in nature due to
unknown and/or varying operating conditions. However, these instructions, combined
with your increasing experience with the deck, will enable you to develop procedures suit-
able to your particular cutting application.
The illustrations and data used in this manual were current at the time of printing, but the
deck may vary slightly due to ongoing engineering changes. Lastec reserves the right to
implement engineering and design changes to the deck as may be necessary without
prior notification.
Throughout this manual, we make references to right and left directions. We determine
right and left while sitting in the operator seat and facing in the direction of forward travel.
Blade rotation is clockwise as viewed from the top of the deck.

NEVER operate the deck with any safety covers removed!
Work safely! Follow all safety rules! A careful operator is the best insurance against
accidents!
Some illustrations in this manual show the deck with safety covers removed in order to
provide improved viewing of the particular components being discussed. This is for
informational purposes only -- never operate the deck without all covers, shields,
safety devices, and grass chute or mulching plate installed and secure!
Safety is a primary concern in the design and manufacture of all Lastec products. Unfor-
tunately, our extensive efforts to provide safe equipment can be negated by a single care-
less act of an operator. In addition to the design and configuration of the deck, hazard
control and accident prevention are also dependent upon the awareness, concern, pru-
dence and proper training of all personnel involved in the operation, transportation, main-
tenance, and storage of the deck.
The best safety device is an informed, careful operator!
We ask you to be that kind of operator.
