Relieving Hydrau lic System Pressure
Before disconnecting or performing any work on the hy-
draulic system, all pressure in the hydraulic system
must be relieved. Park machine on a level surface and
relieve all pressure in the system by lowering the rear at-
tachment fully to the ground. Stop the engine, wait for all
moving parts to come to a complete stop and then re-
move key from ignition switch.
NOTE: If machine is parked on an incline or slope, pres-
sure in the traction circuit WILL NOT be relieved. Also,
make sure that after lowering the rear attachment, the
attachment is not being supported by the lift cylinder.
Towing Machine
If it becomes necessary to tow (or push) the machine,
tow (or push) at a speed below 1 mph (1.6 kph), and for
a very short distance. If machine needs to be moved a
considerable distance, machine should be transported
on an appropriate truck or trailer. Refer to Traction Unit
Operator’s Manual for additional information regarding
towing or transporting.
IMPORTANT: If towing limits are exceeded, s evere
damage to the transmission may occur. Also, if ma-
chine is towed too fast, wheels may lock up. If wheel
lock up occurs, stop towing the machine. Wait for
traction circuit pressure to stabilize before resum-
ing towing at a slower speed.
WARNING
The engine and hydrostatic transmissions can
become very hot and cause severe burns. Allow
the engine and hydrostatic transmissions to cool
completely before accessing the bypass- valve
levers.
Also, stop the engine, remove the ignition key,
and allow all moving parts to stop before access-
ing the transmission bypass- valve levers.
1. Stop the machine on a level surface and turn the igni-
tion key to OFF. Move the control levers to the neutral-
locked position, set the parking brake and r emove the
key from the ignition switch.
2. From beneath the machine, locate the bypass- valve
leversthatareonthetopofeachtransmission(Fig.3).
Rotate the bypass- valve levers so that they point in-
ward, toward the center of the machine. This allows the
hydraulic oil to bypass the internal transmission motors,
enabling the machine wheels to turn freely.
3. Release the parking brake and slowly push machine.
4. When finished moving machine, rotate the bypass -
valve levers so that they point toward the front of the ma-
chine, to allow the machine to drive.
IMPORTANT: M ake sure that transmission bypass
valve levers are in the f ully forward position when
operating the machine. Severe damage to the hy-
draulic system can occur if machine is u sed with
levers in the bypass position.
