Servicing The Spark Plugs - Toro Dingo 323 Operator's Manual

Warning
Battery terminals or metal tools could short
against metal components, causing sparks. Sparks
can cause the battery gasses to explode, resulting
in personal injury.
• When removing or installing the battery, do not
allow the battery terminals to touch any metal
parts of the traction unit.
• Do not allow metal tools to short between the
battery terminals and metal parts of the
traction unit.
5. Disconnect the negative (black) battery cable from the
battery, saving the bolt and wing nut.
6. Disconnect the positive (red) battery cable from the
battery, saving the bolt and wing nut.
7. Gently push the hydraulic hoses aside and lift the
battery out of the chassis.
8. Activate the new battery as directed on the battery
labeling.
9. Install the battery into the chassis (Fig. NO TAG).
10. Secure the battery in the chassis (Fig. NO TAG).
11. Using the bolt and wing nut supplied with the battery,
connect the positive (red) cable to the positive (+)
battery post (Fig. NO TAG). Slide the rubber cover
over the battery post.
Warning
Incorrect battery cable routing could damage the
traction unit and cables, causing sparks. Sparks
can cause the battery gasses to explode, resulting
in personal injury.
• Always disconnect the negative (black) battery
cable before disconnecting the positive (red)
cable.
• Always connect the positive (red) battery cable
before connecting the negative (black) cable.

procedures as directed on the battery labeling.

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. 22).
3. Clean around the spark plugs.
4. Remove the spark plugs and metal washers.

Checking the Spark Plugs
1. Look at the center of the spark plugs (Fig. 23). 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. 23).
