Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.
5 star quality on these downloadable manuals. Easy to read and all the information is there. A must when doing a custom install or needing to service your precious old school electronics.
So usefull to make my installation a breeze. 5 stars on quality.

PRESENTATION
Fuel tank Underneath the tank, there is a fuel filter combined with the fuel valve. The tank can be filled with 2.5 liters/0.66 US Gal in the DT18C or 3.6 liters/0.95 US Gal in the DT18.
Fueling Read the safety instructions before fueling. Keep the fuel and fuel tank clean. Avoid filling the machine with dirty fuel. Make sure the fuel cap is properly tightened and the gasket is not damaged, particularly before washing the machine. Use unleaded gasoline with minimum 86 octane rating. Never use gasoline mixed with two-cycle oil. For ethanol and methanol fuel, the following applies: Maximum allowable ethanol 10% (volume). Maximum allowable methanol 5% (volume). Maximum allowable MTBE (Methyl Tertiary Butyl Ether) 15% (volume). If the engine �bolts� at normal load it can be damaged. Change the fuel. If this does not help, contact an authorized service workshop. Do not fill the tank completely; leave space for the fuel to expand as it warms up. Reduction gear 1:6 The reduction gear only appears on a special version of DT18C with spring tines. The gear is directly coupled to the engine. A V-belt pulley is located on the output axle with a key. The gear reduces the speed of the engine so that the output axle turns at 1/6 of the engine speed.

WARNING! Gasoline is highly flammable. Observe caution and fill the tank outdoors. (See the safety instructions.)
Oil refill reduction gear The oil is filled through the plug (1) at the top of the gearbox until it flows out of the hole for the removed oil level plug (2). Use the same oil type as you used in the engine. The gearbox can be filled with 0.15 liters/0.16 US qt.

Oil level reduction gear The plug (2) is used to check the oil level in the gearbox. When checking, the machine must be parked on level ground. The plug can then be removed and the oil should be level with the hole. The hole is also used to drain the oil, but then the machine must be tipped forwards.
