OPERATION

INSTALLATION REQUIREMENTS

Prior to starting the installation, first read the
ENTIRE "Installation" section of this manual. Since
the cleaning unit (with empty waste tank and
accessories) weighs approximately 810 lbs.
(900 lbs. if mounted on water tank), consider the
following recommendations before installing this
unit.
1. The unit should NOT be mounted in any motor
vehicle of less than 1/2 ton capacity, or 3/4 ton
if equipped with one or more auxiliary fresh
water tanks.
The console with waste tank and accessories
must NOT exceed the vehicle's axle weight limit.
2. If mounting in a trailer, make certain that the
trailer is rated for the total weight of the UNIT
AND TRAILER. Electric or hydraulic brakes
should be provided, and a strict compliance with
any State and Federal vehicle laws must be
maintained.
3. The vehicle tires should have a load rating
above the combined vehicle and unit weight.
4. We do not recommend using flooring materials
that absorb water. This could result in rust and
corrosion of the vehicle floor.
5. Padding under rubber floor mats should be
removed before installing this unit.
6. We highly recommend using a galvanized drip
tray under the console (Part #86050370, PRV
NO. 56-501845, or Part #86050380, PRV NO.
56-501930 for units mounted on a water tank.)
7. If using a trailer, the console should be
positioned so that it balances properly with
respect to the axle. Ten percent (10%) of the
overall unit weight (without accessories or water)
should be on the tongue.

FUEL REQUIREMENTS

Use unleaded gasoline ONLY. DO NOT use any
gasoline additives. We recommend the use of clean,
fresh, unleaded gasoline intended for automotive
use. High octane gasoline should NOT be used with
the engine on this unit. These engines are NOT
designed to use E-85 or Flex Fuels.

ENGINE OIL REQUIREMENTS

Use high quality detergent 10W-30 oil of at least API
(American Petroleum Institute) service class SG,
SH, SJ or higher.
NOTE: Using a lower service class oil or extending
oil change intervals longer than recommended can
cause engine damage.
NOTE: Synthetic oils meeting the listed
classifications may be used with oil changes
performed at recommended intervals. However to
allow piston rings to properly seat, a new or rebuilt
engine should be operated for at least 50 hours
using standard petroleum based oil before switching
to synthetic oil.
ALTITUDE REQUIREMENTS
Engines perform differently with
increases/decreases in altitude. Be sure to check
engine speeds during initial installation. See engine
speeds in Technical Specifications section.
NOTE: To ensure correct engine operation at
86313050 LEGEND GT 09/12/08
altitudes above 1525 meters (5000 ft), it may
be necessary to have an authorized Kohler
dealer install a special high altitude jet kit in
the carburetor. If a high altitude kit has been
installed, the engine must be reconverted to
the original jet size, before it is operated at
lower altitudes, or overheating and engine
damage can result.
