10. Carefully install one of the cylinder heads on one
end of the cylinder rod and push the head onto the
rod until it is snug against the end of the cylinder
barrel.
11. Install one of the cylinder head retainers on the end
of the cylinder barrel and tighten with a suitable
chain wrench.
12. Carefully install the remaining cylinder head on the
opposite end of the cylinder rod and push the head
onto the rod until it is snug against the end of the
cylinder barrel.
13. Install the remaining cylinder head retainer on the
end of the cylinder barrel and tighten with a suitable
chain wrench.
Installation
1. Carefully install the steer cylinder assembly into the
fron axle. Align the cylinder mounting block on the
barrel with the mounting slot in the bottom of the
axle and lower the steer cylinder until the mounting
block rests in the slot.
2. Turn the steer wheels to line up the mounting holes
in the steer spindles and the steer cylinder ends.
Secure each end of the steer cylinder with a bolt and
lock nut.
3. Reconnect the hydraulic hoses to the applicable cyl-
inder ports.
2.12 TILT ALARM SWITCH ADJUSTMENT (IF
EQUIPPED)
NOTE: The machine may be equipped with a tilt alarm
switch (sensor), factory set to activate when the
machine is out of level in any direction at 5° and will
cut out 2 speed drive. Consult factory for tilt sensor
adjustment. The only field adjustment necessary is
leveling the switch on the spring loaded studs. There
are two methods of adjustment, a manual adjust-
ment and an adjustment using a voltmeter.
PERFORM TILT ALARM SWITCH LEVELING PROCEDURE A MINI-
MUM OF EVERY SIX MONTHS TO ENSURE PROPER OPERATION
AND ADJUSTMENT OF SWITCH.
Manual Adjustment
1. Park the machine on a flat, level surface and ensure
the machine is level.
NOTE: Ensure switch mounting bracket is level and securely
attached.
2. Level the base of the indicator by tightening the
three flange nuts. Tighten each nut through approxi-
mately one half of it’s spring’s travel. DO NOT
ADJUST THE “X” NUT DURING THE REMAINDER
OF THE PROCEDURE.
3. With the electrical connections complete, slowly
tighten one of the “Y” nuts until the circuit is closed
(the light on the Platform Control Console illumi-
nates, the tilt alarm sounds).
4. Slowly back off the nut, counting the number of
turns, until the circuit is closed again.
5. Divide the number of turns determined in step 4 in
half. Tighten the nut this many turns. The line deter-
mined by this nut and the “X” nut is now parallel to
the ground.
6. Repeat steps 3 through 5 for the remaining “Y” nut.
The switch is now level.
7. Individually push down on one corner at a time;
there should be enough travel to cause the switch to
trip. If the switch does not trip in all three tests, the
flange nuts have been tightened too far. Loosen the
“X” nut and repeat steps 3 through 7.
Voltmeter Adjustment
1. Park the machine on a flat, level surface and ensure
the machine is level.
2. If the motor is not running, turn the ignition switch to
ON
