SETUP

Setup
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.

TO PREVENT SERIOUS INJURY: Operate only with proper spark arrestor installed.
Operation of this equipment may create sparks that can start fires around dry vegetation. A spark arrestor may be required. The operator should contact local fire agencies for laws or regulations relating to fire prevention requirements.
High Altitude Operation Above 3000 feet

WARNING! To prevent serious injury from fire: Follow instructions in a well- ventilated area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before proceeding. Do not smoke.

NOTICE: Warranty void if necessary adjustments are not made for high altitude use.

At high altitudes, the engine’s carburetor, governor (if so equipped), and any other parts that control the fuel-air ratio will need to be adjusted by a qualified mechanic to allow efficient high-altitude use and to prevent damage to the engine and any other devices used with this product. The fuel system on this engine may be influenced by operation at higher altitudes. Proper operation can be ensured by installing an altitude kit at altitudes higher than 3000 ft. above sea level. At elevations above 8000 ft, the engine may experience decreased performance, even with the proper main jet. Operating this engine without the proper altitude kit installed may increase the engine’s emissions and decrease fuel economy and performance. The kit should be installed by a qualified mechanic.

1. Turn off the engine.

2. Close the fuel valve.

3. Place a bowl under the fuel cup to catch any spilled fuel.

CAUTION! Carburetor bowl may have gas in it which will leak upon removing the bolt.

4. Unthread the bolt holding the fuel cup.

5. Remove the bolt, Bolt Seal, fuel cup, Fuel Cup Seal and Main Jet from the body of the carburetor assembly. A carburetor screwdriver (not included) is needed to remove and install the Main Jet.

Note: The mixing tube is held in place by the Main Jet and might fall out when it is removed. If it falls out, replace it in the same orientation before replacing the Main Jet.

6. Replace the Main Jet with the replacement Main Jet needed for your altitude range (part 1a or 2a).
Note: The Fuel Cup Seal and Bolt Seal may be damaged during removal and should be replaced with the new ones from the kit.

SAFETY

Locating the Water Pump
Locate the Water Pump on a flat, level, sturdy surface capable of supporting the weight of the Pump.
1. For best Pump performance, place the Pump near the water level and use hoses that are no longer than necessary. See diagram below.

Discharge Head

Total Head

2. Route the Intake Hose with the Intake Strainer fully immersed in the water supply source.
3. Place Strainer into water to be pumped. NOTICE: Immerse strainer fully in water. Do not operate Pump without Strainer connected to end of suction hose. Keep Strainer out of sand or silt by placing Strainer in a bucket or on stones.
NOTICE: Air leaks must not appear in the suction line. If there is an air leak in the suction line, you will not be able to prime the pump. Use a thread sealant to seal air leaks.

Water Pump

Suction Head

As the head (pumping height) increases, pump output decreases. A non- collapsible suction hose must be used. The length, type, and size of the suction and discharge hoses can significantly affect Pump output.
Discharge head capability is always greater than suction head capability. This means pumping height for the Intake Hose (suction head) should be shorter than the pumping height for the Discharge Hose.
Minimizing suction head (placing the Pump closer to the water level) will also help make it easier to prime the pump (fill it with water).

Strainer
4. Secure the Intake Hose in place to keep it from moving once the Pump is turned on. The Intake Hose should be as short as possible for more efficient operation.
5. Route the discharge hose to the desired discharge location. If necessary, connect additional discharge hoses to direct the discharge to the desired location. Make sure to secure the discharge hose in place to keep it from moving once the Water Pump is turned on. The discharge hose should be kept as short as possible for more efficient operation.

Spark Plug Maintenance

Spark Plug Cap
1. Disconnect spark plug cap from end of plug.
Clean out debris from around spark plug. 2. Using a spark plug wrench, remove the spark plug. 3. Inspect the spark plug:
If the electrode is oily, clean it using a clean, dry rag. If the electrode has deposits on it, polish it using emery paper. If the white insulator is cracked or chipped, the spark plug needs to be replaced.

Recommended Spark Plug

TORCH®

E4RC

NOTICE: Using an incorrect spark plug may damage the engine.
4. When installing a new spark plug, adjust the plug’s gap to the specification on the Specifications chart. Do not pry against the electrode, the spark plug can be damaged.
5. Install the new spark plug or the cleaned spark plug into the engine. Gasket-style: Finger-tighten until the gasket contacts the cylinder head, then tighten about 1/2-2/3 turn more. Non-gasket-style: Finger-tighten until the plug contacts the head, then tighten about 1/16 turn more.
NOTICE: Tighten the spark plug properly. If loose, the spark plug will cause the engine to overheat. If overtightened, the threads in the engine block will be damaged.
6. Apply dielectric spark plug boot protector (not included) to the end of the spark plug and reattach the wire securely.

Long Term Storage

When the equipment is to remain idle for longer than 20 days, prepare the engine for storage as follows:
1. CLEANING: Wait for engine to cool, then clean engine with dry cloth. NOTICE: Do not clean using water. The water will gradually enter the engine and cause corrosion damage. Apply a thin coat of corrosion preventive oil to all metal parts.
2. FUEL: To protect the fuel tank during storage, fill the tank with gasoline that has been treated with a fuel stabilizer additive. Follow fuel stabilizer manufacturer’s recommendations for use. Refer to Checking and Filling Fuel on page 14.
WARNING! TO PREVENT SERIOUS INJURY FROM FIRE: Fill tank in a well-ventilated area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before adding fuel. Do not smoke.
3. LUBRICATION:
a. Change engine oil.
b. Clean out area around spark plug. Remove spark plug and pour one tablespoon of engine oil into cylinder through spark plug hole.

c. Replace spark plug, but leave spark plug cap disconnected.
d. Pull Starter Handle to distribute oil in cylinder. Stop after one or two revolutions when you feel the piston start the compression stroke (when you start to feel resistance).
4. BATTERY: Disconnect battery cables (if equipped). Recharge batteries monthly while in storage.
5. STORAGE AREA: Cover and store in a dry, level, well-ventilated area out of reach of children. Storage area should also be away from ignition sources, such as water heaters, clothes dryers, and furnaces.
NOTICE: For every 3 months of an extended storage period, the pump must be connected to a water supply, primed, started, and allowed to run for 15­20 minutes or the Warranty is VOID.
6. AFTER STORAGE: Before starting the engine after storage, keep in mind that untreated gasoline will deteriorate quickly. Drain the fuel tank and change to fresh fuel if untreated gasoline has been sitting for a month, if treated gasoline has been sitting beyond the fuel stabilizer’s recommended time period, or if the engine does not start.
