Belt Maintenance

Servicing the Alternator
Belt
Service Interval: Every 100 hours
Proper tension of the belt allows 10 mm (3/8 inch) of
deflection when a force of 4.5 kg (10 lb) is applied on
the belt midway between the pulleys.
If the deflection is not 10 mm (3/8 inch), loosen the
alternator-mounting bolts
Note:
Increase or decrease the alternator-belt
tension and tighten the bolts. Check the deflection of
the belt again to ensure that the tension is correct.

Hydraulic System Safety

•
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.
•
Seek immediate medical attention if fluid
is injected into skin. Injected fluid must be
surgically removed within a few hours by a
doctor.
Checking the
Hydraulic-Fluid Level
Service Interval: Before each use or daily
The reservoir is filled at the factory with approximately
28.4 L (7.50 US gallons) of high-quality hydraulic fluid.
Check the level of the hydraulic fluid before the engine
g020537
is first started and daily thereafter. The recommended
replacement fluid is as follows:
Toro Premium All Season Hydraulic Fluid
(Available in 19 L (5 US gallons) pails or 208 L (55 US
gallons) drums. See the Parts Catalog or your Toro
Distributor for part numbers).
Alternative fluids: If the Toro fluid is not available,
other conventional, petroleum-based fluids may be
used, provided they meet all of the following material
properties and industry specifications. Check with
your oil supplier to see whether the oil meets these
specifications.
Note:
Toro does not assume responsibility for
damage caused by improper substitutions, so use
only products from reputable manufacturers who will
stand behind their recommendation.
