Your new 2-stroke Solo auger engine does not come filled with a
fuel/oil mix. You will need to add a fuel/oil mix prior to your first use.
(See below) Fuel is highly flammable. Keep away from open flames
and never spill fuel. Do not smoke at the operating site or near the
refueling site.
• Stop the engine prior to refueling.
• Let the engine cool down before refueling.
• Open fuel cap slowly to allow any excess pressure in the tank to be
reduced without the risk of fuel spraying out.
• Fuel may contain substances similar to solvents. Wear protective
gloves during filling.
• Avoid breathing in fuel vapor.
• Immediately clean any spilled fuel on the machine.
• Firmly tighten fuel cap.
• Check for fuel leaks. Do not start the machine or work with the
machine if there is a fuel leak.
• Store fuel and oil in an approved and correctly labeled container.
1. The Solo engine has a non-vented gas cap which is not visible.
Air is supplied to the tank using an external venting system. (Fig 1)
2. You will notice the air line located under the fuel cap. The airline
needs to maintain this position in order to allow air to the tank. (Fig 2)
3. To prevent excessive fuel from collecting in the air line we have
the following suggestions. DO NOT OVER FILL THE GAS TANK.
4. When the auger is not in use, lay it down as shown. Position #1 (Fig 3)
is the best option followed by position #2. (Fig 4)
This will keep the air line out of the fuel.
FUEL INFORMATION
• Use unleaded regular, unleaded premium or non-oxygenated
fuel. Do not use fuel with less than an octane rating of 87. For peak
performance use a 90-93 octane rated unleaded premium fuel.
• Do not use leaded fuel or E85.
• FUEL MUST BE FRESH AND CLEAN. NEVER use fuel left over
from last season or fuel that has been stored more than 30 days.
Do not use summer blend fuel; only use winter blend fuel which is
available after November 1st.
• Unsuitable fuel or deviations in mixing ratio may lead to serious
engine damage which is not covered under warranty.
2-CYCLE OIL/FUEL MIX
To operate your engine you will need to use a clean, high-quality,
2-cycle oil. We recommend StrikeMaster 2-cycle Low Smoke Engine
Oil mixed with fuel at a ratio of 40:1 (3.2 fl. oz. to 1 gallon of gasoline).
DO NOT use a fuel/oil mixture leaner than 50:1 (2.6 fl. oz. to 1 gallon
of gasoline).
• All 2-stroke engines will have some oil residue that slowly comes
from the muffler area; this is normal.
• Full Synthetic 2-stroke oil may be used as long as fuel/oil mixture
ratio does not exceed 50:1 (2.6 fluid oz. oil to 1 gal. gas).
