RECOMMENDED OIL TYPE
Using the proper type and weight of oil in the crankcase is extremely important.
Check the oil before each use and change the oil regularly. Failure to use the correct
oil, or using dirty oil, can cause premature engine wear and failure.
Use a high-quality SAE 30 weight oil of API (American Petroleum Institute) service
class SF, SG, SH.
ADDING OIL TO CRANKCASE: INITIAL USE
NOTE: This unit is shipped without oil. In order to avoid damage to the unit, put
oil in the crankcase before attempting to start the unit.
The unit is supplied with one 3.04 fluid oz. (90 ml) bottle of SAE 30 SF, SG, SH oil (Fig. 1).
NOTE: Save the bottle of oil. It can be used to measure the correct amount during
future oil changes. See Changing the Oil.
1. Unscrew the top of the bottle of oil and remove the paper seal covering the
opening. Replace the top. Next, cut the tip off the funnel spout (Fig. 1).
2. Place unit on a flat, level surface.
3. Remove the oil fill plug from the crankcase (Fig. 3).
4. Pour the entire bottle of oil into the oil fill hole (Fig. 2).
NOTE: Never add oil to the fuel or fuel tank.
5. Wipe up any oil that may have spilled and reinstall the oil fill plug.
Check oil before each use and change as needed. Refer to Checking the Oil Level.
RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper unit performance. Be sure to use fresh,
clean, unleaded gasoline.
NOTE: Dispose of the old gasoline in accordance with federal, state and local
regulations.
NOTE: This is a four cycle engine. In order to avoid damage to the unit, do not
mix oil with gasoline.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol or MTBE (ether). Alcohol-
blended fuel absorbs water. As little as 1% water in the fuel can make fuel and oil separate or form acids when stored.
Use fresh fuel (less than 30 days old), when using alcohol-blended fuel.
Using Blended Fuels
If choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL® or an equivalent
• Drain tank and run the engine dry before storing unit

OPERATING INSTRUCTIONS
HOLDING THE UNIT
Before operating the unit, stand in the operating position (Fig. 8). Check for the following:
• The operator is wearing eye protection and proper clothing.
• Both hands are holding the handle bar firmly.
• The edger wheel adjusted for proper cut depth as shown in Figure 9 and edger
positioned as shown in Figure 8.
ADJUSTING EDGER CUTTING DEPTH
1. Gently pull the depth adjustment lever away from the wheel bracket (Fig 9).
2. To raise the cutting blade, move the lever toward the front of the wheel bracket
(Fig. 9). Lowering the wheel decreases the cutting depth.
3. To lower the cutting blade, move the lever toward the rear of the wheel bracket.
Raising the wheel increases the cutting depth.
TIPS FOR BEST EDGING RESULTS
• After starting the engine, keep the unit tilted back so the blade does not touch the
ground. Move the unit to the desired location and slowly lower the blade into the
ground.
• Do not force the edger. Edge the first time at a lesser depth (no more than 1/2”
depth cut per pass), then do the area again with a deeper setting.
• Walk the edger at a slow, even pace.
• Check the blade condition (Fig. 10). As it wears it becomes smaller, thus reducing
the cutting depth performance. Replace the blade when it no longer makes
contact with the ground.
WARNING: Always wear eye, hearing, foot and body protection to
reduce the risk of injury when operating this unit.
