MAINTENANCE
INSPECTING/CLEANING THE SPARK ARRESTOR
Inspect and clean the spark arrestor every 100 hours of
operation (refer to page 23, Table 4). The spark arrestor
is located outside the muffler, which gets very hot during op-
eration. Allow the engine to cool completely before servicing
the spark arrestor.
1. Remove the Phillips-head screw that secures the spark
arrestor to the muffler. See Fig. 15.
2. Remove the spark arrestor screen.
3. Carefully clean and remove the carbon deposits from the
spark arrestor screen with a wire brush. Replace the spark
arrestor if it is damaged. Replacement spark arrestors can
be purchased from wenproducts.com by searching the part
number GN400i-1101.1.
4. Reinstall the spark arrestor in the muffler and secure it in
place with the screws.

SPARK PLUG MAINTENANCE
Inspect and change the spark plug every 100 hours of operation (refer to page 23, Table 4). The spark plug is
important for proper engine operation. Check the spark plug regularly to maintain proper engine operation. A good
spark plug should be intact, free of deposits, and properly gapped.
1. Gently pull on the spark plug boot to remove it (Fig. 15). Be careful not to tear insulation or wire.
2. Use the included spark plug wrench (page 9, slide the handle into the hole on the wrench) to unscrew the
spark plug from the engine. Remove the spark plug from the engine. TIP: There is limited space for the wrench to
turn. Use both rows of holes in the spark plug wrench to gain leverage to loosen the plug.
3. Visually inspect the spark plug. If it is cracked or chipped, or if the electrodes are worn or burned, discard it and
replace with a new spark plug. We recommend replacing it with an F6RTC spark plug. These can be purchased from
wenproducts.com by searching part number 56310i-0104.
4. If re-using the spark plug, use a wire brush to clean any dirt from around the spark plug base, then re-gap the
spark plug.
