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

1. Fuel tank cap
2. Remove the fuel tank cap.
3. Fill the tank until the level is 1/4 to 1/2 inch (6 to
13 mm) below the bottom of the filler neck. Do not
overfill. Install the cap.
4. Wipe up any fuel that may have spilled.

Checking the Cooling System

The capacity of the cooling system is approximately 4.9 quarts
(4.6 l). Refer to Cleaning the Radiator Screen (page 42).

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 (Figure 31). It should be
between the lines on the reserve tank when the engine
is cold.

Checking the Hydraulic Fluid
Level
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:

Recommended Hydraulic Fluid
The machines reservoir is filled at the factory with
approximately 5.5 gallons (20.8 l) of high quality hydraulic
fluid. Check the level of the hydraulic fluid before
the engine is first started and daily thereafter. The
recommended replacement fluid is as follows:
