Troy-Bilt TB516, Operation Manual

Page: 3 / 12

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

OIL AND FUEL INFORMATION
STARTING AND STOPPING INSTRUCTIONS
WARNING:
OVERFILLING OIL CRANKCASE MAY CAUSE SERIOUS PERSONAL INJURY. Check and
maintain the proper oil level in the crankcase; it is important and cannot be overemphasized. Check the
oil before each use and change it as needed. See
Changing the Oil .

Using Fuel Additives
The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent, will inhibit corrosion and minimize the
formation of gum deposits. Using a fuel additive can keep fuel from forming harmful deposits in the carburetor for up to
six (6) months. Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel according to the instructions on the fuel additive
container. NEVER add fuel additives directly to the unit's gas tank.
FUELING THE UNIT
1. Remove the fuel cap (Fig. 4).
2. Place the gas container’s spout into the fill hole on the fuel tank (Fig. 4) and fill the tank.
NOTE: Do not overfill the tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling source and site before starting the engine.

WARNING:
DO NOT USE E85 FUEL IN THIS UNIT. It has been
proven that fuel containing greater than 10% ethanol will likely
damage this engine and void the warranty.
WARNING:
Remove fuel cap slowly to avoid injury from fuel spray.
Never operate the unit without the fuel cap securely in place.
WARNING:
Operate this unit only in a well-ventilated outdoor area. Carbon monoxide exhaust fumes
can be lethal in a confined area.
WARNING:
Add fuel in a clean, well ventilated outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilt fuel. Do not start the engine until fuel vapors dissipate.
IF USING THE OPTIONAL ELECTRIC STARTER OR POWER START BIT™ ACCESSORY
HOW TO START THE UNIT USING THE ELECTRIC STARTER OR POWER START BIT™ ACCESSORY
NOTE: This unit can use an Electric Starter or Power Start Bit™ optional accessory!
Please refer to the Electric Starter or Power Start Bit™ operator’s manual for proper use of this feature.
(Items Sold Separately! Please refer to page 4 of this manual about purchasing these accessories.)
STARTING INSTRUCTIONS
1. Check the oil level in the crankcase. Refer to Checking the Oil Level .
2. Fill the fuel tank with fresh, clean unleaded gasoline. Refer to Fueling the Unit .
NOTE: There is no need to turn the unit on. The On/Off Control is in the ON (I) position at all times (Fig. 5).
IF COLD... In cold weather conditions (below 40°F), push the red cold weather start lever (Fig. 6) down to the closed
position and continue to step 3. DO NOT push this lever down if the temperature is above 40°F.
NOTE: DO NOT squeeze the throttle control until step 9.
3. Fully press and release the primer bulb 10 times, slowly. Some amount of fuel should be visible in the primer bulb
(Fig. 6). If fuel cannot be seen in the bulb, press and release the bulb until fuel is visible.
4. Place the electric starter or Power Start Bit™ into the back of the unit. Refer to the Operation section of the Electric
Starter or Power Start Bit™ operator’s manual.
5. Press and hold the ON (I) button of the Electric Starter or Power Start Bit™ equipped drill in intervals no longer
than 2 seconds each until the unit starts.
IF COLD... In cold weather conditions (below 40°F), pull the red cold weather start lever back up to the open position
after the unit starts.
6. Remove the electric starter or drill from the unit.
7. Wait 60 seconds.
8. Stand in the starting position (Fig. 7). Tip the unit back so the blade does not touch the ground.
9. Squeeze the throttle control and allow the engine to warm up for 30 to 60 seconds. The unit may be used during
this time.
IF... The engine does not start, go back to step 3.
IF... The engine stops while squeezing the throttle, go back to step 4.
IF ENGINE IS HOT... Go back to step 3.
STOPPING INSTRUCTIONS
1. Release the throttle control and allow the engine to cool down by idling.
2. Press and hold the On/Off Control in the OFF (O) position until the unit comes to a complete stop. (Fig. 5)
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.
