Servicing The Spark Plugs; Servicing The Hydraulic System - Toro 22305 Operator's Manual

2. Remove the filler caps from the battery and connect a
3 to 4 amp. battery charger to the battery posts. Charge
the battery at a rate of 4 amperes or less for 4 hours
(12 volts). Do not overcharge the battery.
3. Install the filler caps after the battery is fully charged.
Warning
Charging the battery produces gasses that can
explode.
Never smoke near the battery and keep sparks
and flames away from battery.

Servicing the Spark Plugs

Check the spark plugs after every 200 operating hours.
Ensure that the air gap between the center and side
electrodes is correct before installing each spark plug. Use
a spark plug wrench for removing and installing the spark
plugs and a gapping tool/feeler gauge to check and adjust
the air gap. Install new spark plugs if necessary.
Type: Champion Premium Gold 2071 or Champion
RC12YC (or equivalent) Air Gap: 0.030 in. (0.76 mm)
Removing the Spark Plug
1. Lower the loader arms and stop the engine. Remove
the key.
2. Pull the wires off of the spark plugs (Fig. 24).

Checking the Spark Plugs
1. Look at the center of the spark plugs (Fig. 25). If you
see light brown or gray on the insulator, the engine is
operating properly. A black coating on the insulator
usually means the air cleaner is dirty.
Important
Never clean the spark plugs. Always
replace the spark plugs when they have a black coating,
worn electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Fig. 25).
3. Bend the side electrode (Fig. 25) if the gap is not
correct.

2. Tighten the spark plugs to 20 ft.-lb (27 N.m).
3. Push the wires onto the spark plugs (Fig. 24).
