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.
1. Position the machine on a level surface, lower the
cutting units, and stop the engine.
2. Check the fluid level by viewing it in the sight gauge
(Figure 29).
If the fluid is cold, the level should be at the bottom
of the gauge. If the fluid is hot, the level should be
at the center of the gauge.

1. Hydraulic reservoir cap
3. To prevent system contamination, clean the top of
the hydraulic fluid containers before puncturing.
Ensure that the pour spout and funnel are clean.
Also, clean around the hydraulic reservoir cap.
4. If the fluid level is not at least at the bottom of the
gauge when it is cold, remove the cap from the
hydraulic fluid reservoir (Figure 29) and slowly fill
the reservoir with high quality hydraulic fluid until
the level in it reaches the bottom of the sight gauge.
Do not overfill.
5. Install the reservoir cap. Wipe up any fluid that may
have spilled.
Checking the Tire Pressure
Service Interval: Before each use or daily
Check to ensure that the air pressure in the tires is
16–20 psi (110–138 kPa).
Important: Maintain the recommended pressure
in all tires to ensure a good quality-of-cut
and proper machine performance. Do not
under-inflate.
2. Sight gauge
Note: The tires are over-inflated for shipping.
Therefore, release some of the air to reduce the pressure
before using the machine for the first time.
Checking the Reel to Bedknife
Contact
Service Interval: Before each use or daily
Each day before operating, check reel to bedknife
contact, regardless if the quality of cut had previously
been acceptable. There must be light contact across
the full length of the reel and the bedknife (refer to
Adjusting the Reel to Bedknife in the cutting unit
Operator's Manual).
Check the Torque of the Wheel
Nuts
Service Interval: After the first hour
After the first 10 hours
Every 250 hours
Torque the wheel lug nuts to 45 to 65 ft-lb (61 to 88
N-m).
Failure to maintain proper torque of the wheel
nuts could result in personal injury.
Bleeding the Fuel System
Bleed the fuel system before starting the engine if any
of the following situations have occurred:
• Initial start up of a new machine.
• Engine has ceased running due to lack of fuel.
• Maintenance has been performed upon fuel system
components; i.e., filter replaced, separator serviced,
etc.
