Draining Water From The Fuel Filter - Toro 04383 Operator's Manual

Biodegradable Hydraulic Fluid – Mobil 224H
Toro Biodegradable Hydraulic Fluid (Available in 5
gallon pails or 55 gallon drums. See parts catalog or Toro
distributor for part numbers.)
Alternate fluid: Mobil EAL 224H
This is vegetable–oil based biodegradable oil tested and
approved by Toro for this model. This fluid is not as
resistant to to high temperatures as standard fluid, so
install an oil cooler if required by the operator manual
and follow recommended fluid change intervals with
this fluid. Contamination by mineral–based hydraulic
fluids will change the biodegradability and toxicity of
this oil. When changing from standard fluid to the
biodegradable type, be certain to follow the approved
flushing procedure. Contact your local Toro Distributor
for details.
Note: Use of this fluid requires installation of an
Oil Cooler Kit, Part No. 104–7701, to the machine.
This biodegradable fluid will break down quickly if the
temperature exceeds 180°F (82°C).
Premium Biodegradable Hydraulic Fluid—Mobil
EAL EnviroSyn 46H
Important: Mobil EAL EnviroSyn 46H is the only
synthetic biodegradable fluid approved by Toro.
This fluid is compatible with the elastomers used
in Toro hydraulic systems and is suitable for a
wide–range of temperature conditions. This fluid
is compatible with conventional mineral oils, but
for maximum biodegradability and performance
the hydraulic system should be thoroughly flushed
of conventional fluid. The oil is available in 5
gallon (19 l) containers or 55 gallon drums from
your Mobil Distributor.
Note: Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic system oil is available in 2/3 oz. (20 ml)
bottles. One bottle is sufficient for 4–6 gal. (15–22 l)
of hydraulic oil. Order Part No. 44-2500 from your
Authorized Toro Distributor. This red dye is not
recommended for use with biodegradable fluids.
Use food coloring.
Filling the Hydraulic Tank
1. Position the machine on a level surface. Make sure
the machine has cooled down so the oil is cold.
2. Remove the cap from the reservoir and check the
level of fluid. The fluid should be up to the bottom
of the screen in the filler neck (Figure 33).

3. If the fluid level is low, slowly fill the reservoir with
the appropriate hydraulic fluid until the level reaches
the bottom of the screen. Do not overfill.
Important: To prevent system contamination,
clean the top of the hydraulic fluid containers
before puncturing. Ensure the pour spout and
funnel are clean.
4. Install the reservoir cap. Wipe up any fluid that may
have spilled.
Important: Check level of hydraulic fluid
before engine is first started and daily thereafter.
Draining Water from the Fuel
Filter
Any water accumulation should be drained from the
fuel filter before each use.
1. Position the machine on a level surface and stop
the engine.
2. Place a drain pan under the fuel filter.
3. Open the drain plug on the fuel filter approximately
one turn and drain any accumulated water (Fig. 26).
Tighten the plug after draining.
Note: Because the accumulated water will be
mixed with diesel fuel, drain the fuel filter into a
suitable container and dispose of it properly.
