Checking The Front Differential Oil Level (Four-Wheel Drive Models Only); Checking The Torque Of The Wheel Nuts; Checking The Tire Pressure - Toro 07383 Operator's Manual

WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure all hydraulic fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to the hydraulic system.
• Keep your body and hands away from
pin hole leaks or nozzles that eject high
pressure hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks.
• Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
• Seek immediate medical attention if fluid
is injected into your skin.
Checking the Front Differential
Oil Level (Four-wheel drive
models only)
Service Interval: Every 100 hours/Monthly (whichever
comes first)
The differential is filled with Mobil 424 hydraulic oil.
1. Position the vehicle on a level surface.
2. Clean the area around the fill/check plug on side of
the differential (Figure 18).
Figure 18
1. Fill/check plug
3. Remove the fill/check plug and check the level of the
oil. The oil should be up to hole. If the oil is low, add
Mobil 424 hydraulic oil.
4. Install the fill/check plug.
2. Drain plug
Checking the Torque of the
Wheel Nuts
Service Interval: After the first 2 hours
After the first 10 hours
Every 200 hours
WARNING
Failure to maintain proper torque of the wheel nuts
could result in failure or loss of a wheel and may
result in personal injury.
Torque the front and rear wheel nuts to 109 to 122
N-m (80 to 90 ft-lb) after 1 to 4 hours of operation
and again after 10 hours of operation. Torque every
200 hours thereafter.

Checking the Tire Pressure

Service Interval: Before each use or daily
The maximum air pressure in the front tires is 220 kPa (32
psi) and the rear tires is 124 kPa (18 psi).
Check the tire pressure frequently to ensure proper inflation.
If the tires are not inflated to the correct pressure, the tires
will wear prematurely.
Figure 19 is an example of tire wear caused by under inflation.
1. Under inflated tire
Figure 20 is an example of tire wear caused by over inflation.
