FUELING THE SAW
FUELING THE SAW
This saw features a 6 gallon, clear, molded plastic fuel
tank for ease of checking the fuel level. It has a central
drain and a shutoff valve. The fuel tank cap is located at
the front of the control panel console and a fuel gauge tube
is featured on the front of the console.
1. Determine if the engine fuel is low (Figure 20).
2. If fuel level is low, remove the fuel filler cap and fill
with diesel fuel (Cetane fuel number 45 or greater).
CAUTION — Fuel Safety
Handle fuel safely.
Motor fuels are highly flammable and can be
dangerous if mishandled.
DO NOT smoke while refueling.
DO NOT attempt to refuel the saw if the engine is hot or
running.
Avoid spilling fuel on the control panel or engine. Clean up
fuel spills to avoid falls from slipping.
DO NOT overtighten the fuel tank cap.
WARNING — Diesel Fuel only
Use DIESEL FUEL ONLY.
NEVER use gasoline or fuels not specifically for use in
the Deutz Diesel engine.

Priming the Fuel System
The saw utilizes a fuel primer bulb (Figure 21, item A) or
button (item B), when fueling the saw for the first time or
refilling after running out of fuel.
Primer Bulb Systems: Locate the fuel primer bulb inside
the console beneath the fuel tank, and squeeze the fuel
priming bulb until it fills with fuel (it will become firm when
properly primed), priming the fuel transfer pump.
Primer Button Systems: Locate primer button and simply
press button to prime the system.
WARNING — Fuel
DO NOT crank the engine without fuel in the line
between the tank and the primary fuel pump to prevent
damage to the primary fuel transfer pump.

CAUTION — Fuel
DO NOT store with fuel in the tank for an extended
period of time. Completely drain fuel system (tank, lines,
etc.) if the unit is to be put into long term storage. For
shorter or intermediate periods of time, the tank should
be filled to avoid condensation that could cause
contamination of the fuel.
