Belt Maintenance

Servicing the Alternator Belt

Service Interval: Every 100 hours
1. Check the tension of the alternator belt by depressing
it midway between the alternator and the crankshaft
pulleys with 4.5 kg (10 lb) of force.
Note: The belt should deflect 10mm (3/8 inch). If the
deflection is incorrect, proceed to step 2. If correct,
continue operation.
2. Loosen the alternator-mounting bolts
3. 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 the skin.
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
is as follows:
Toro Premium All Season Hydraulic Fluid (Available in 19
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.
