Check The Cooling System - Toro REELMASTER 3100-D Operator's Manual

Because diesel fuel is flammable, use caution
when storing or handling it. Do not smoke while
filling the fuel tank. Do not fill the fuel tank while
the engine is running, hot, or when the machine is
in an enclosed area. Always fill the fuel tank
outside and wipe up any spilled diesel fuel before
starting the engine. Store the fuel in a clean,
safety-approved container and keep the cap in
place. Use Diesel fuel for the engine only; not for
any other purpose.

CHECK THE COOLING SYSTEM

(Fig. 4 & 5)
Clean debris from the radiator and oil cooler daily;
hourly if conditions are extremely dusty and dirty; refer
to Cleaning The Radiator.
1. 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. Cooling system
capacity is 5.7 L.
If the engine has been running, pressurized hot
coolant can escape when the radiator cap is
removed and cause burns. Only open the radiator
cap when the engine is cold.

2. Check the level of coolant in the expansion tank.
With a cold engine, coolant level should be midway
between the marks on side of the tank.

3. If coolant level is low, remove the expansion tank
cap and replenish the system. DO NOT
OVERFILL.
4. Install the expansion tank cap.
CHECK THE HYDRAULIC
SYSTEM FLUID (Fig. 6)
The hydraulic system driving the reels is designed to
operate on anti-wear hydraulic fluid. The machine's
reservoir is filled at the factory with 13.2 L of DTE 15M
hydraulic fluid. Check the level of hydraulic fluid before
the engine is first started and daily thereafter.
IMPORTANT: Use only the types of hydraulic fluids
specified. Other fluids could cause system damage.
Note: A red dye additive for the hydraulic system fluid is
available in 2/3 oz. bottles. One bottle is sufficient for
15-19 L. of hydraulic fluid. Order Part No. 44-2500 from
your Authorized Toro Distributor.
1. Position the machine on a level surface, lower the
cutting units and stop the engine.
2. Clean the area around the filler neck and cap of
hydraulic tank. Remove the cap from the filler neck.
