Belt Maintenance

Servicing the Alternator
Belt
Service Interval: After the first 10 hours
Every 100 hours
1. Proper tension allows 10 mm (3/8 inch)
deflection when a force of 4.5 kg (10 lb) is
applied on the belt midway between the pulleys.
2. If the deflection is not 10 mm (3/8 inch), loosen
the alternator mounting bolts
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

WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• 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.
Checking the
Hydraulic-Fluid Level
Service Interval: Before each use or daily
The hydraulic tank of the machine is filled at the
factory with approximately 37.8 L (10 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
is as follows:
Toro Premium All Season Hydraulic Fluid (Available in
18.9 L (5 US gallon) pails or 208 L (55 US gallon) drums.
See the Parts Catalog or your Toro Distributor for part
numbers.)
Alternate fluids: If the Toro fluid is not available, other
fluids may be used provided they meet all the following
material properties and industry specifications. We
do not recommend the use of synthetic fluid. Consult
with your lubricant distributor to identify a satisfactory
product.
Note:
Toro will not assume responsibility for damage
caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.
