Checking The Cooling System; Checking The Hydraulic-Fluid Level - Toro Greensmaster TriFlex 3420 Operator's Manual

Checking the Cooling
System
The capacity of the cooling system is approximately
4.6 L (4.9 US qt). Keep the radiator screen clean;
refer to Cleaning the Radiator Screen (page

Fill the cooling system with a 50/50 solution of water
and permanent ethylene glycol antifreeze. Check
the level of the coolant at the beginning of each day
before starting the engine.
CAUTION
If the engine has been running, the
pressurized, hot coolant can escape and
cause burns.
• Do not open the radiator cap when the
engine is running.
• Use a rag when opening the radiator cap,
and open the cap slowly to allow steam to
escape.
1. Park the machine on a level surface.
2. Check the coolant level

It should be between the lines on the
reserve tank when the engine is cold.

and add a 50/50 mixture of water and permanent
ethylene glycol antifreeze. Do not overfill.

Checking the
Hydraulic-Fluid Level
The hydraulic-fluid reservoir is filled at the factory
with approximately 25.7 L (6.8 US gallons) of high
quality hydraulic fluid. Before operating the machine
each day, check level of the hydraulic fluid in the
white plastic window on the front of the hydraulic-fluid
reservoir (behind the seat on the left side). The fluid
should be between the lines in the window; if not,
add an appropriate fluid as described in the following
sections:
The recommended replacement fluid is as follows:
Toro Premium All Season Hydraulic Fluid (Available in
5-gallon pails or 55-gallon drums. See parts catalog or
Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other
fluids may be used provided they meet all the following
material properties and industry specifications. We
do not recommend the use of synthetic fluid. Consult
with your lubricant distributor to identify a satisfactory
product
Note:
Toro will not assume responsibility for damage
caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.
