All Regulators
Every 1500 Hours:
Complete cleaning (disassembling, servicing, and
resetting) of regulator at 1500 hour intervals is
recommended. As all adjustments and settings must
be reset using specific test equipment, this must be
performed by an authorized Kohler Engine Service
Dealer or qualified LP personnel only.
Lock-Off/Filter Assembly
This opens, closes, and filters the liquid fuel flow from
the supply tank before reaching the vaporizer.
Servicing, if required, is to be performed by an
authorized Kohler Engine Service Dealer or qualified
LP personnel only. See Figure 13.
Vaporizer
The vaporizer changes the Liquified Petroleum (LP)
from the supply tank to a gaseoushapor state. Other
than keeping the body clean, no maintenance,
adjustment, or servicing is required. See Figure 13.
Leakage ChecWTesting
Every 500 hours or annually. With LPG tank valve
fully opened, engine not running, turn key switch "on."
Check all LPG system connections and lines for leaks
using soapy water. Any leakage must be corrected
before restarting engine. Have service performed by
an authorized Kohler Engine Service Dealer or
qualified LP personnel only.
Troubleshooting
-
Fuel Related
If engine problems are experienced that appear to be
fuel system related, check the following areas before
seeking service assistance.
Make sure the LPG tank is properly filled (never to
more than 80 percent of total capacity). An air
space must be present in the tank to allow fuel to
expand.
Make sure the air cleaner element is clean and all
air cleaner components are fastened securely.
Check for loose, kinked, or cracked vacuum lines
causing regulator not to open.
Check to make sure the fuel valve on LPG tank is
fully open.
Check gauge on LPG tank to make sure pressure
is sufficient to open the regulator.
For problems with the gasoline system (dual-fuel),
check that there is adequate fresh fuel in the tank,
the fuel valve at the tank (if so equipped) is open,
the fuel tank cap is properly vented, the lines are
not kinked or blocked, and that the in-line filter is
not dirty or restricted.
If after checking the items listed above, the engine is
hard to start, runs roughly, or stalls at low idle speed,
qualified fuel system servicing may be necessary.
Contact your nearest authorized Kohler Engine Service
Dealer for further assistance.
Troubleshoofing
When troubles occur, be sure to check the simple causes which at first may seem too obvious to be considered.
For example, a starting problem could be caused by an empty fuel tank. Some common causes of engine troubles
are listed in the following table.
Do not attempt to service or replace major engine components, or any items that require special timing or
adjustment procedures. Have your Kohler Engine Service Dealer do this work.
