Cleaning The Blower Housing; Fuel System Maintenance; Replacing The In-Line Fuel Filter - Toro TimeCutter SS 5060 Operator's Manual

Checking the Spark Plug
Important: Do not clean the spark plug(s). Always
replace the spark plug(s) when it has: a black coating,
worn electrodes, an oily film, or cracks.
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.
Set the gap to 0.76 mm (0.030 inch).

Installing the Spark Plug
1. Install the spark plug.
Note: Make sure that the air gap is set correctly.
2. Tighten the spark plug to 25 to 29 N-m (18 to 22 ft-lb).
3. Push the wire onto the spark plug (Figure 32).

Cleaning the Blower Housing

To ensure proper cooling, make sure that the grass screen,
cooling fins, and other external surfaces of the engine are
kept clean at all times.
Annually, or every 100 hours of operation (more often
under extremely dusty, dirty conditions), remove the blower
housing, and any other cooling shrouds. Clean the cooling
fins and external surfaces as necessary. Make sure the cooling
shrouds are installed. Torque the blower housing screws to
7.5 N-m (5.5 ft-lb).
Important: Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or cooling
shrouds removed, will cause engine damage due to
overheating.
