Adjusting The Front Wheel Toe-In; Cooling System Maintenance; Checking The Coolant Level - Toro 41593 Operator's Manual

Adjusting the Front Wheel
Toe-in
Service Interval: Every 200 hours/Yearly (whichever comes
first)
The toe-in should be 0 to 3 mm (0 to 1/8 inch).
1. Check and fill all tires; refer to Checking Tire Pressure.
2. Measure the distance between both of the front tires at
the axle height at both the front and rear of the front
tires (Figure 52).
The distance between the front of the tires should be 0
to 3 mm (0 to 1/8 inch) less than the distance between
the back side of the front tires.

3. If the measurement does not fall within the specified
range, loosen the jam nuts at both ends of the tie rod
(Figure 53).

Cooling System
Maintenance

Checking the Coolant Level

Service Interval: Before each use or daily
The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol antifreeze. Check the level
of coolant in the radiator and the expansion tank at the
beginning of each day before starting the engine. The cooling
system capacity is 5.5 L (5.8 US qt).
CAUTION
If the engine has been running, the coolant may
be hot and pressurized. If you open the radiator
cap when the coolant is hot, it could spray out and
severely burn you or bystanders.
Allow the engine to cool for at least 15 minutes
before opening the radiator cap.
1. Position the sprayer on a level surface.
2. Set the parking brake, stop the pump, stop the engine,
and remove the ignition key.
3. Carefully remove the radiator cap and the expansion
tank cap (Figure 54).

4. Check the coolant level in the radiator and in the
expansion tank.
Note: The radiator should be filled to the top of the
filler neck and the expansion tank filled to the Full
mark.
5. If coolant level is low, remove the expansion tank cap
and the radiator cap, and fill expansion tank to the Full
mark and the radiator to the top of the filler neck.
