Checking The Cooling System; Removing Debris From The Traction Unit - Toro 22303 Operator's Manual

Checking the Cooling System

The cooling system is filled with a 50/50 solution of
water and permanent ethylene glycol anti–freeze.
Check the level of coolant at the beginning of each
day, before starting the engine.
POTENTIAL HAZARD
Coolant is hot and pressurized.
WHAT CAN HAPPEN
Discharge of hot pressurized coolant can
cause severe burns.
HOW TO AVOID THE HAZARD
Do not remove the radiator cap when the
engine is hot. Always allow the engine to
cool at least 15 minutes or until the
radiator cap is cool enough to touch
without burning your hand before
removing it.
1. Park the traction unit on a level surface, lower
the loader arms, and stop the engine. Remove
the key.
2. Allow the engine to cool.
3. Remove the radiator filler cap and check the
coolant level (Fig. 8). The coolant should be up
to filler neck.
4. If coolant level is low, replenish the system.
IMPORTANT: Do not over fill the radiator.
5. Replace the radiator filler cap, ensuring that it is
tightly sealed.

Removing Debris from the
Traction Unit
IMPORTANT: Operating the engine with a
blocked radiator, may result in engine
damage from overheating.
1. Park the traction unit on a level surface, raise the
loader arms, and install the cylinder locks; refer
to Using the Cylinder Locks, page 22.
2. Stop the engine and remove the key.
3. Remove the front access cover, refer to
Removing the Front Access Cover, page 27.
4. Clean any debris from the grill.
5. Open the rear access cover; refer to Opening the
Rear Access Cover, page 27.
6. Wipe away debris from the air cleaner.
7. Clean any debris build–up on the engine with a
brush or blower before each use.
IMPORTANT: It is preferable to blow dirt
out, rather than washing it out. If water is
used, keep it away from electrical items and
hydraulic valves. Do not use a high-pressure
washer. High-pressure washing can damage
the electrical system and hydraulic valves or
deplete grease.
8. Replace and secure the front and rear access
covers.
