Checking the Coolant Level in
the Reservoir
Service Interval: Before each use or daily
If the engine overheat warning is displayed on the control
panel, check the coolant level in the reservoir and add coolant
if it is low. Also inspect the engine compartment around the
radiator and clear away any obstructions to air flow.
1. Park the machine on a level surface, stop the engine,
and remove the ignition key.
2. Allow the engine to cool.
3. Remove the left side panel; refer to
Panels (page

and 3/4 of the way up in the sight glass
5. Add the specified coolant until the coolant level is
between 1/4 and 3/4 of the way up in the sight glass.
Note: Ensure that the coolant solution is thoroughly
mixed before filling the reservoir.

Service Interval: Before each use or daily
Use Toro Premium All-season Hydraulic Fluid (available
in 5-gallon pails or 55-gallon drums. See the Parts Catalog or
an Authorized Toro Service Dealer for part numbers).
If Toro hydraulic fluid is not available, you may use an
equivalent hydraulic fluid, provided that it meets all the
following material properties and industry specifications. Do
not use a synthetic hydraulic fluid. Consult with your
lubricant distributor to identify a satisfactory product.

Note: Many brands of hydraulic fluid are almost colorless,
making it difficult to detect leaks. A red dye additive for the
hydraulic system oil is available in 20 ml (0.68 oz) bottles.
One bottle is sufficient for 15.1 to 22.7 L (4.0 to 6.0 US
gal) of hydraulic fluid; you can order this additive from an
Authorized Toro Service Dealer.
1. Park the machine on a level surface, and put all the
attachments in the transport position.
