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 is first started
and daily thereafter. The recommended replacement fluid
g020537
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.
