Hydraulic System - HUSTLER Super104 Operator's Manual

WARNING
Shorts caused by battery terminals or metal tools touch-
ing metal mower components can cause sparks. Sparks
can cause a battery gas explosion which will result in per-
sonal injury.
• Prevent the battery terminals from touching any
metal mower parts when removing or installing the
battery.
• Do not allow metal tools to short between the bat-
tery terminals and metal mower parts.
WARNING
Incorrect battery cable routing could cause damage to the
mower and battery cables. This can cause sparks which
can cause a battery gas explosion which will result in per-
sonal injury.
• Always disconnect the negative (black) battery
cable(s) before disconnecting the positive (red)
cable(s).
• Always connect the positive (red) battery cable(s)
before connecting the negative (black) cable(s).
Master in-line fuse
These mowers have a master in-line fuse in the electrical
system. This is the main fuse to protect the complete electrical
system. It is located at the left front corner of the engine. Figure

Hydraulic System

IMPORTANT: Never use hydraulic or automatic transmis-
sion fluid in this system; use only motor oil as specified.
Remember, dirt is the primary enemy of any hydraulic system.
Hydraulic fluid escaping under pressure may have
sufficient force to penetrate skin and cause serious
injury. Foreign fluid injected into the skin must be
surgically removed within a few hours by a doctor,
familiar with this form of injury, or gangrene may
result.
Before applying pressure to hydraulic system, make
sure all connections are tight and all hoses and lines
are in good condition. To find a leak under pressure,
use a piece of cardboard or wood — never use your
hands. Relieve all pressure in the system before dis-
connecting or working on hydraulic lines. To relieve
pressure, lower all attachments and shut off engine.
Check oil level in hydraulic system after every 50 hours of
operation or weekly, whichever occurs first. Check more often if
system appears to be leaking or otherwise malfunctioning.
Fluid level should be 1" (2.54cm) from top of reservoir. Use
only 15W50 Mobil 1 oil. Figure 4-2
Change hydraulic system filter element and oil after first 50
hours of mower operation, then replace filter and oil in reservoir
every 500 hours thereafter.
The Super 104 system filter is located inside the hydraulic
reservoir on the underneath side of the tank. Use a Hustler
approved filter element only. When changing the filter use a 15/
16" socket. The threads are right hand. Figure 4-3

Hydraulic oil heat exchanger
The Super 104 is equipped with a hydraulic oil heat
exchanger. The heat exchanger coils must be kept clean to
insure that the hydraulic oil is operating within the correct
temperature range.
