ENGINES ON SABRE LAWN TRACTORS ARE ENVIRONMENTALLY FRIENDLY!
All Briggs & Stratton engines used on the SABRE lawn tractors are California Air Resources
Board (C.A.R.B.) approved. In order to meet the established emissions standards, the
carburetors on these C.A.R.B. approved engines, are calibrated leaner than those engines which
do not pass the C.A.R.B. standard. The result, for the consumer, is an ENVIRONMENTALLY
FRIENDLY ENGINE which requires a longer warm-up period during which the choke should be
opened slowly, in small steps, during the warm-up phase. Engines which are not allowed to
warm-up properly may experience surging when the blade drive lever is engaged and the
engine is put under load. To help the consumer understand and become aware of this warm-
up procedure, SABRE has implemented a removable decal on the console of all SABRE lawn
tractors. A sample of this decal is below:
Whenever possible, the consumer should be given instruction, by the dealer or retailer, of the
proper starting and warm-up procedure for these ENVIRONMENTALLY FRIENDLY, C.A.R.B.
approved engines.
The following statement also appears in the Briggs & Stratton Engine Owner's Manuals ("Starting"
section) which are packaged with all SABRE lawn tractors:

ENGINE SURGING WHEN COLD
SABRE Lawn Tractors
Choke operation/engine warm-up
This engine is designed for maximum performance and
life if operated with the choke fully open (in RUN) and
throttle fully open (in FAST). To open the choke fully
requires an engine warm-up period of several seconds
to several minutes, depending on temperature.
After starting engine, first open the choke (toward RUN)
until the engine just begins to run smoothly. Then open
the choke in small steps, allowing the engine to accept
changes in speed and load, until the choke is fully open
(in RUN).
During engine warm-up, the equipment can be operated.
