Safety information

Take care not to spill any fuel on the engine or muf- fler when refueling.

Do not leave the multi-purpose engine inside the vehicle or in the trunk.

If you swallow any fuel, inhale fuel vapor, or allow any to get in your eye(s), see your doctor immediately. If any fuel spills on your skin or clothing, immediately wash with soap and water and change your clothes.

When refueling, do not place the fuel tank cap near the muffler.

When operating or transporting the machine, be sure it is kept upright. If it tilts, fuel may leak from the car- buretor or fuel tank.

Engine and muffler may be hot Place the machine in a place where pedestrians or

children are not likely to touch the machine.

7VE-F8199-72-E0.book 2

Safety information

Avoid placing any flammable materials near the exhaust outlet during operation.

In order to prevent overheating, ensure adequate air- flow by keeping the machine at least 1 m (3 ft) from objects or other equipment.

Do not operate the engine with a dust cover or other objects covering it.

When covering the multi-purpose engine, be sure to do so only after the engine and muffler have com- pletely cooled down.

Electric shock prevention Never operate the engine in rain or snow.

7VE-F8199-72-E0.book 3

4

Safety information

Never touch the machine with wet hands or electrical shock will occur.

Accidental engine start prevention To prevent the engine from accidentally starting, be

sure to stop the engine and remove the spark plug caps before doing any service.

Starting circuit is switched on. The starter motor starts and the engine can be started. After starting the engine, take your hand off the switch immediately.

Oil warning light (Red) When the oil level falls below the lower level, the oil warning light comes on and then the engine stops automatically. Unless you refill with oil, the engine will not start again.

TIP (Manual starting models) If the engine stalls or does not start, turn the engine switch to (ON) and then pull the recoil starter. If the oil warning light flickers for a few seconds, the engine oil is insufficient. Add oil and restart. (Electric starting models) If the engine stalls or does not start, turn the engine switch to (START). If the oil warning light comes on, the engine oil is insufficient. Add oil and restart.

Preparation

Fuel

TIP For using a fuel tank cap of A, if filled beyond the bot- tom of the fuel filler, fuel may mix with the active char- coal located within the fuel tank cap and soil the surrounding areas.

1. Stop the engine.

2. Place the multi-purpose engine on a level surface. 3. Remove the fuel tank cap.

4. Check the fuel level.

Fuel is highly flammable and poisonous. Check Safety information (See page 1) care- fully before filling.

Carefully fill the fuel tank in order to avoid fuel from spilling out of the fuel tank.

Stop filling when the fuel reaches the bottom of the fuel filler, otherwise it may overflow when the fuel warms up and expands.

Wipe up any spilled fuel immediately. After filling the tank with fuel, make sure the fuel

tank cap is tightened securely.

Do not overfill the fuel tank, otherwise it may over- flow when the fuel warms up and expands.

Pre-operation check

The condition of a multi-purpose engine is the owners responsibility. Vital components can start to deteriorate quickly and unexpectedly, even if the multi-purpose engine is unused.

TIP Pre-operation checks should be made each time the multi-purpose engine is used.

Pre-operation check Fuel

- Check fuel level in fuel tank. - Refuel if necessary.

(See page 15 for more details.) Fuel line

- Check fuel hose for crack or damage. - Replace if necessary.

Engine oil - Check oil level in engine. - If necessary, add recommended oil to correct level. - Check multi-purpose engine for oil leakage.

(See page 17 for more details.) The point where abnormality was recognized by

use - Check operation. - If necessary, consult a Yamaha dealer.

1. Connect the battery positive terminal to the starter switch.

2. Ground the battery negative terminal to the engine mounting bolt.

If any item in the pre-operation check is not work- ing properly, have it inspected and repaired before operating the multi-purpose engine.

Periodic maintenance

Spark plug inspection The spark plug is important engine components, which should be checked periodically. 1. Remove the spark plug cap and the spark plug.

2. Check for discoloration and remove the carbon. The porcelain insulator around the center elec- trode of spark plug should be a slightly colored light gray.

3. Check the spark plug type and gap.

TIP The spark plug gap should be measured with a wire thickness gauge and, if necessary, adjusted to specifi- cation.

4. Install the spark plug and then tighten it.

TIP If a torque wrench is not available when installing a spark plug, a good estimate of the correct torque is 1/41/2 turn past finger tight. However, the spark plug

5. Install the spark plug cap.

Carburetor adjustment The carburetor is a vital part of the engine. Adjusting should be left to a Yamaha dealer with the professional knowledge, specialized data, and equipment to do so properly.

Engine oil replacement

1. Place the multi-purpose engine on a level surface and warm up the engine for several minutes. Then stop the engine and turn the fuel cock lever to OFF.

2. Remove the oil filler cap.

3. Place an oil pan under the engine. Remove the oil drain bolt and gasket so that the oil can be com- pletely drained.

4. Check the oil drain bolt, oil filler cap and O-ring. Replace them if damaged.

5. Install a new gasket and the oil drain bolt, and then tighten the bolt.

Avoid draining the engine oil immediately after stopping the engine. The oil is hot and should be handled with care to avoid burns.

10. Tighten further if any screws, bolts and nuts are loose.

11. Store the multi-purpose engine in a dry, well-venti- lated place, with the cover placed over it.

Engine Perform the following steps to protect the cylinder, pis- ton ring, etc. from corrosion.

1. Remove the spark plug, pour about one table- spoon of engine oil (See page 29) into the spark plug hole and reinstall the spark plug only. Recoil start the engine by turning over several times (with ignition off) to coat the cylinder walls with oil.

2. Pull the recoil starter until you feel compression. Then stop pulling. (This prevents the cylinder and valves from rusting.)

3. Clean exterior of the multi-purpose engine and apply a rust inhibitor.

4. Store the multi-purpose engine in a dry, well-venti- lated place, with the cover placed over it.

5. The multi-purpose engine must remain in a vertical position when stored, carried or operated.
