REPLACING THE CUTTING BLADE

See figure 8.

Be careful when replacing the mower blade. Ensure that 
your 

fi

 ngers do not get caught between the moving blade 

and the 

fi

 xed parts of the product.

For best results, the mower blade must be kept sharp. 
Replace a bent or damaged blade immediately.

 WARNING

Only use replacement blades approved by the 
manufacturer. Using a blade that is not approved by 
the manufacturer of the product is hazardous and could 
result in serious injury, damage to the product, and will 
void your warranty.

 WARNING

Drain the fuel 

fi

 rst before tilting the mower to replace the 

blade.

■

Stop the engine and disconnect the spark plug wire. 
Allow blade to come to a complete stop.

■

Turn the product on its side (carburetor facing up).

■

Wedge a block of wood between the blade and mower 
deck to prevent the blade from turning.

●

Installing: See figure 8a.

●

Removing: See figure 8b.

■

Using a 9/16-in. wrench or socket (not provided), loosen 
the blade bolt by turning the bolt in a counterclockwise 
direction as viewed from the bottom of the mower.

■

Remove the blade bolt, lock washer, flat washer, and 
blade.

■

Place the new blade on the shaft. Make sure it is 
installed with the curved ends pointing up toward the 
mower deck and not down toward the ground.

■

Replace the flat washer, lock washer, and blade bolt 
on the shaft. Finger tighten the bolt by turning in a 
clockwise direction as viewed from the bottom of the 
mower.

NOTE:

 Make certain all parts are replaced in the exact 

order in which they were removed.

■

Torque the blade bolt down using a torque wrench (not 
provided) to ensure the bolt is properly tightened.

■

The recommended torque for the blade bolt is 48–55 
Nm (35–40 ft.lb.).

NOTE: 

Do not sharpen the blades, replace with new 

item. Blades need to be properly balanced to avoid 
damage and personal injury.

CLEANING AIR FILTER

See figure 9.

■

For proper performance and long life, keep the air filter 
clean.

■

Remove the air filter cover by pushing in on the latch 

with your thumb while gently pulling on the cover.

■

squeeze it out using an absorbent cloth or paper towel.

■

Reinstall the air filter into the air filter base.

■

Replace and secure the air filter cover. 

NOTE: 

The 

fi

 lter should be replaced annually for best 

performance.

FUEL CAP

 WARNING

A leaking fuel cap is a 

fi

 re 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 ENGINE OIL

See figure 10.

■

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

■

Engine oil should be changed after every 20 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.

■

Remove the oil fill cap/dipstick.

■

Tip mower onto its side and allow oil to drain from the oil 
fill hole into an approved container.

■

Place mower 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.

SPARK PLUG MAINTENANCE

See figure 11.

■

The spark plug must be properly gapped and free of 
deposits in order to ensure proper engine operation. To 
check:

■

Remove spark plug boot.

■

Clean any dirt from around base of spark plug.

■

Remove spark plug using a 13/16 in. spark plug socket 
(not provided).

■

Inspect spark plug for damage, and clean with a wire 
brush before reinstalling. If insulator is cracked or 
chipped, spark plug should be replaced.

NOTE: 

If replacing, use the following recommended 

spark plugs or equivalent:TORCH F7RTC or LG 
F7RTC.

■

Measure plug gap. The correct gap is 0.71 mm
