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

•
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 machines reservoir 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.
