FUEL CAP

 WARNING

A leaking fuel cap is a fire hazard and must be replaced 
immediately.

The fuel cap contains a non-serviceable 

fi

 lter and a 

check valve. A clogged fuel cap will cause poor engine 
performance. If performance improves when the fuel cap 
is loosened, check valve may be faulty or clogged. Replace 
fuel cap if required.

CHANGING THE ENGINE OIL

See figure 14.

Ensure the fuel tank is completely empty before tipping the 
unit over; otherwise, fuel will leak out.

Engine oil should be changed after every 25 hours of use. 
Change the oil while the engine oil is still warm, but not hot. 
This allows the oil to drain quickly and completely.
1.  Remove the oil fill cap/dipstick.
2.  Tip mower onto its side and allow oil to drain from the oil 

fill hole into an approved container.

3.  Place the product upright and refill with oil following the 

instructions in the Adding/Checking Oil section.

NOTE: 

Used oil should be disposed of at an approved 

disposal site. See your local oil retailer for more 
information.

MAINTAINING THE SPARK PLUG

See figure 15.

The spark plug must be properly gapped and free of 
deposits in order to ensure proper engine operation. To 
check:
1.  Remove the spark plug boot.
2.  Clean any dirt from around base of the spark plug.
3.  Remove the spark plug using a 13/16 in. spark plug 

socket (not provided).

4.  Inspect the spark plug for damage, and clean with a 

wire brush before reinstalling. If the insulator is cracked 
or chipped, spark plug should be replaced.

NOTE: 

Use the recommended E6RTC spark plug for 

replacement.

5.  Measure the plug gap. The correct gap is 0,71 mm - 

0,79 mm. To widen the gap, if necessary, carefully bend 
the ground (top) electrode. To lessen the gap, gently tap 
the ground electrode on a hard surface.

6.  Seat the spark plug in position; thread in by hand to 

prevent cross-threading.

7.  Tighten with wrench to compress the washer. If the 

spark plug is new, use 1/2 turn to compress the washer 
appropriate amount. If reusing an old spark plug, use 
1/8 to 1/4 turn for proper washer compression.

NOTE: 

An improperly tightened spark plug will become 

very hot and could damage the engine.

8.  Reinstall the spark plug boot.

MAINTAINING THE DRIVE GEAR

See figure 16.

To ensure smooth operation of the wheels, the wheel 
assembly should be cleaned before storage.
1.  Remove the hub cap.
2.  Remove the nut and the wheel and set aside.
3.  Remove the dust cover, e-ring, washer, pins, and the 

wheel gear. Clean any dirt from these items and the 
end of the drive shaft by wiping with a dry cloth. If 
necessary, rubbing alcohol may be used to remove any 
stubborn dirt.

 WARNING

Do not lubricate any of the wheel components. 
Lubrication may cause the wheel components to fail 
during use, which could result in product damage and/
or serious personal injury to the operator.

4.  Reinstall the wheel gear with the arrows facing the front 

of the product. Reinstall pins, washer, e-rings, and dust 
cover.

NOTE:

 Ensure the left gear and right gear are in their 

correct location.

5.  Reinstall the wheel and the nut. Tighten the nut to 

secure.

6.  Reinstall the hub cap.

REPLACING THE WHEELS

See figure 17.

 WARNING

Only use replacement wheels approved by the 
manufacturer of the product. Using wheels that are 
not approved by the manufacturer  of the product  is 
hazardous and could result  in serious personal injury.

1.  Stop the engine and disconnect the spark plug wire. 

Allow blade to come to a complete stop.

2.  Remove the hub cap.
3.  Remove the nut from the wheel axle, then remove the 

wheel. 

4.  Replace with new wheel and reinstall nut to secure.
