Setting The Hydraulic Pump; Neutral Position - Toro 74416 Operator's Manual

Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• If hydraulic fluid is injected into the skin
it must be surgically removed within a
few hours by a doctor familiar with this
type of injury. Gangrene may result if
this is not done.
• Keep body and hands away from pin hole
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.
• Make sure all hydraulic fluid hoses
and lines are in good condition and
all hydraulic connections and fittings
are tight before applying pressure to
hydraulic system.

Setting the Hydraulic Pump

Neutral Position

Note: Adjust the handle neutral first. That needs
to be correct before the following adjustment can
be made.
This adjustment must be made with drive wheels
turning.
Mechanical or hydraulic jacks may fail to
support machine and cause a serious injury.
• Use jack stand when supporting
machine.
• Do not use hydraulic jacks.
Engine must be running so motion control
adjustment can be performed. Contact with
moving parts or hot surfaces may cause
personal injury.
Keep hands, feet, face, clothing and other
body parts away from rotating parts, muffler
and other hot surfaces.
1. Raise the frame and block up the machine so
drive wheels can rotate freely.
2. Disconnect the electrical connector from
the seat safety switch. Temporarily install
a jumper wire across terminals in the wiring
harness connector.
3. Unlatch the seat and slide seat forward.
4. Disconnect the seat rod and tilt the seat fully
forward.
