Checking The Hydraulic System - Toro Reelmaster 3100-D Series Operator's Manual

1. Radiator
The cooling system is filled with a 50/50 solution
of water and permanent ethylene glycol antifreeze.
Check the coolant level at the beginning of each day
before starting the engine.
The capacity of the cooling system is approximately
5.7 L (6 US qt).
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. Check the coolant level in the expansion tank
(Figure 40).

1. Expansion tank
Note:
With a cold engine, the coolant level
should be approximately midway between the
marks on the side of the tank.
2. If the coolant level is low, remove the expansion
tank cap and replenish the system. Do not
overfill.
3. Install the expansion tank cap.
Checking the Hydraulic
System
Service Interval: Before each use or daily—Check
The hydraulic-fluid tank is filled at the factory with
approximately 13.2 L (3.5 US gallons) of high-quality
hydraulic fluid. Check the level of the hydraulic
fluid before the engine is first started and daily
thereafter.
The best time to check the hydraulic fluid is when the
fluid is cold. The machine should be in its transport
configuration. If the fluid level is below the Add mark
on the dipstick, add fluid to bring the fluid level to the
middle of the acceptable range. Do not overfill the
tank. If the oil level is between the Full and the Add
marks, no fluid addition is required.
The recommended replacement fluid is Toro
Premium All Season Hydraulic Fluid (Available in
5-gallon pails or 55-gallon drums. Refer to the parts
catalog or a Toro distributor for part numbers.)
Alternative fluids: If the Toro fluid is not available,
other conventional, petroleum-based fluids may be
used, provided that they meet all the following material
properties and industry specifications. Check with
