How to Check, Clean and Change the Air Filter
Check the air filter every 25 hours of use or more frequently if used
under dusty conditions. A clogged air filter may increase fuel
consumption while cutting down the engine power. Never operate the
blower without the air filter or with a deformed filter element because
unfiltered dusty air will quickly ruin the engine.
Cleaning air filter
1. Remove the air cleaner cover by pulling the tab on side and take out
the 2 filter element.
2. Use neutral detergent and warm water to clean the filter elements.
After cleaning, air dry the element completely and moisten with a
small amount of motor oil.
3. Place the filter element into the air cleaner housing and press the
cover against the housing until it clicks.
Idle Speed Adjustment
1. Warm up engine before adjusting idle speed.
2. The idle speed adjustment screw controls the throttle opening at idle
position.
3. When the engine tends to stop frequently at idling mode, turn the
adjusting screw clock wise.
4. If the tines continue to rotate after releasing the trigger, turn the
adjusting screw counter-clockwise.
Clear Blockages From the Fuel Line & Filter
After you’ve used your Tiller/Cultivator for a few seasons, check for
blockages in the fuel tank and fuel filter. Such blockages can keep your
Tiller/Cultivator from starting.
Clear any blockages you see in the tank, fuel filter, or fuel line.
Remember: The fuel filter is located inside the tank. (See Picture 3)
Then use the normal starting procedure to start your Tiller/Cultivator.
Spark Plug
1. Starting failure and mis-firing are often caused by a fouled spark
plug. Clean the spark plug and check the that the plug gap is in the
correct range. (Picture 4) (.025., 0.65 mm)
2. CAUTION: Do not over tighten the spark plug. To install the spark
plug first turn the plug until it is finger tight, then tighten it a quarter
turn more with a socket wrench.
3. For a replacement plug, use the correct type specified by RedMax.
The replacement plug is Champion RCJ6Y (5602-73110)
