Adjusting the PTO-Clutch
Gap
Service Interval: Every 200 hours
1. Allow the engine to cool.
2. Raise the engine hood.
3. Adjust the air gap so that a 0.3 mm (0.012 inch)
feeler gauge slides in between the clutch lining
and friction plate with light pressure
Note:
You can decrease the gap by turning
the adjusting nuts clockwise
maximum service gap is 0.6 mm (0.024 inch).
Adjust all 3 air gaps to 0.4 mm (0.012 inches).

Hydraulic System Safety

•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
•
Ensure that 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 pinhole
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.
Hydraulic Fluid
Specifications
The reservoir is filled at the factory with approximately
22.7 L (6 US gallons) of high-quality hydraulic fluid.
Check the level of the hydraulic fluid before the engine
is first started and daily thereafter; refer to
the Hydraulic-Fluid Level (page
Recommended replacement fluid: Toro PX
Extended Life Hydraulic Fluid; available in 19 L (5 US
gallon) pails or 208 L (55 US gallon) drums.
Note:
A machine using the recommended
replacement fluid requires less frequent fluid and filter
changes.
Alternative hydraulic fluids:If Toro PX Extended Life
Hydraulic Fluid is not available, you may use another
conventional, petroleum-based hydraulic fluid having
specifications that fall within the listed range for all the
following material properties and that it meets industry
standards. Do not use synthetic fluid. Consult with
your lubricant distributor to identify a satisfactory
product.
Note:
Toro does not assume responsibility for
damage caused by improper substitutions, so use
products only from reputable manufacturers who will
stand behind their recommendation.
