Servicing The Spark Plug - Toro 22610 Operator's Manual

Underneath the fuel valve is a sediment cup to catch dirt in
the fuel.
1. Move the fuel valve to the Off position, all the way
to the left.
2. Unscrew the sediment cup. Make sure not to misplace
the o-ring (Figure 17).

3. Clean the reservoir and the o-ring using a cleaning
solvent and dry carefully.
Note: Make sure not to misplace the o-ring.
4. Put the o-ring in place in the groove of the cup and
replace the sediment cup.
5. Turn the fuel valve to the On position, all the way to the
right, and check for leaks. If it leaks, replace the o-ring.

Servicing the Spark Plug

Service Interval: Every 100 hours—Check the spark plugs.
Ensure that the air gap between the center and side electrodes
is correct before installing the spark plug. Use a spark plug
wrench for removing and installing the spark plug and a
gapping tool/feeler gauge to check and adjust the air gap.
Install a new spark plug if necessary.
Type: BPR6ES (NKG) or equivalent
Air Gap: 0.28–0.031 inch (0.70-0.80 mm)
Removing the Spark Plug
1. Lower the grinder and stop the machine; Refer to
Stopping the Engine (page 10).
2. Pull the wire off of the spark plug (Figure 18).

3. Clean around the spark plug.
4. Remove the spark plug and the metal washer.
Checking the Spark Plug
1. Look at the center of the spark plug (Figure 19). If you
see light brown or gray on the insulator, the engine is
operating properly. A black coating on the insulator
usually means that the air cleaner is dirty.
Important: Do not clean the spark plug. Always
replace the spark plug when it has a black coating,
worn electrodes, an oily film, or cracks.

2. Side electrode
2. Check the gap between the center and side electrodes
(Figure 19). Bend the side electrode (Figure 19) if the
gap is not correct.
Installing the Spark Plug
1. Thread the spark plug into the spark plug hole.
2. Tighten the spark plug to 20 ft-lb (27 N-m).
3. Push the wire onto the spark plug.
