MAINTENANCE AND PARTS MANUAL
GB
When changing from one type of hydraulic fluid to
the other, care must be taken to drain all of the old
fluid from the system. Some brands of the 32/46
multi-viscosity type are not fully compatible with
some brands of the ISO 46 straight-viscosity type.
When using Texaco products, the two types are
compatible.
The 32/46 Multi-Viscosity fluids listed are premium
hydraulic oils and will allow for oil change intervals
of 200 hours (or yearly), with normal operation,
within the temperature guidelines stated. The ISO
46 straight-viscosity fluids require a 150-200 hour oil
change interval for severe duty and/or extremely
high operating temperature conditions, longer
intervals for normal operation.
HYDRAULIC OIL FILTER
When replacing the hydraulic oil filter (PN 522972),
apply a light film of clean oil to the rubber seal.
Screw filter on until the seal contacts the oil filter
base, then tighten 1/2 turn more.
DO NOT use wrench when replacing the filter, use
hand pressure ONLY.
ACCESSORY
TURF PROTECTION SYSTEM
(electronic leak detector)
If the Turf Protection System (TPS) has been
installed, it will need to be recalibrated if the oil level
has been changed (refer to the TPS instructions that
came with the accessory).
NOTICE
• You will need to re–calibrate the Turf
Protection System before each days use,
for the first five days of operation after
installation or oil change.
• To avoid damage to the hydraulic system,
repair any leaks and refill the system
immediately.
•
DO NOT
substitute any other type of fluid
except for those listed on Page 16, in the
Hydraulic Oil Section of this manual.
•
DO NOT
over fill the hydraulic system.
• Clean debris from the hydraulic oil cooler
fins daily to prevent overheating.
ENGINE COOLING SYSTEM
IMPORTANT!
REFER TO THE ENGINE OPERATOR’S MANUAL
FOR ADDITIONAL COOLING SYSTEM
MAINTENANCE.
DRAINING COOLANT SYSTEM
WARNING
•
To prevent burns or scalding, be sure
cooling system has had time to cool before
attempting to remove radiator cap.
If coolant requires draining, remove radiator cap,
open the drain cock located on the cylinder block
directly below the fuel injection pump). Close drain
cock before filling.
FILLING COOLANT SYSTEM
NOTICE
• Failure to follow the recommended
procedure for filling the cooling system will
cause engine overheating and possible
engine failure.
•
ALWAYS
check coolant level in the
radiator. The correct level of coolant in
the reservoir tank does
NOT
assure the
radiator is full.
• A 50/50 mixture of water and ethylene
glyco (antifreeze) must be mixed in a
separate container before adding.
NEVER
add straight antifreeze to the radiator. The
mixture must
NEVER
be more than 50%
antifreeze. Refer to engine operator’s
manual.
Add coolant to the radiator until it is up to the bottom
of the filler port. DO NOT install cap.
If the block has been drained, start and run the
engine until the coolant level in the radiator drops.
Stop engine.
Add coolant to the bottom of the filler port again.
Install radiator pressure cap. Add coolant to the
proper line on the over flow tank.
CLEANING RADIATOR
Check radiator for dirt accumulation.
Clean with compressed air. DO NOT use water
under pressure unless all water is blown from the
radiator after cleaning. Water will collect dirt and
clog radiator fins.
NOTICE
• Use care when cleaning radiator with
compressed air or water under pressure.
Damage may occur to cooling fins.
AIR CLEANER
Diesel Engines: use a large capacity dry type air
cleaner with a replaceable paper element (PN
840352).
NOTICE
• DO NOT use bent or dented air cleaner
housing
• DO NOT use bent or dented air cleaner
