Cleaning The Cooling Systems; Checking The Tire Pressure; Servicing The Fuse - Toro Proline 30187 Operator's Manual

Installing the Spark Plug
1. Install the spark plug(s) and metal washer. Make sure
the air gap is set correctly.
2. Tighten the spark plug(s) to 20 ft-lb (27 NS m).
3. Push the wire(s) onto the spark plug(s) (Figure 22).

Cleaning the Cooling Systems

Before each use, check and clean hydraulic and engine
cooling systems. Remove any build–up of grass, dirt or
other debris from the oil cooler screen and engine air
intake. Every 100 hours clean oil cooler, engine cylinder
and cylinder head cooling fins. Also clean around
carburetor, governor levers and linkage. This will help
insure adequate cooling to hydraulic pumps, motors and
engine and will reduce the possibility of overheating and
mechanical damage.
1. Remove oil cooler from the engine (Figure 24). Save all
mounting hardware.
2. Blow out fins of oil cooler and area between fins and
screen with compressed air. If area between screen and
fins is tightly packed, remove oil cooler from screen.
Removing two retaining screws (Figure 24). Save all
mounting hardware.
3. Clean off engine air intake (Figure 24).
4. Install oil cooler onto engine with previously removed
hardware (Figure 24).

Checking the Tire Pressure

Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause uneven cut.
Check the pressure at the valve stem after every
50 operating hours or monthly, whichever occurs first
(Figure 25). Check the tires when they are cold to get the
most accurate pressure reading.
Pressure: 12–14 psi (83–97 kPa) drive wheel.
