MACHINE WARMUP
PROCEDURE
HYDRAULIC FLUID WARMUP
DO NOT ENGAGE THE CLUTCH UNLESS
THE HYDRAULIC
FLUID IS AT LEAST 32

F (0

C). RUNNING
THE HYDRAULICS
AT TEMPERATURES BELOW THIS LEVEL
MAY CAUSE EXTENSIVE
DAMAGE TO THE MACHINE.
The machine can be used ONLY after the
hydraulic fluid has reached a minimum
temperature of 60° F (15°C).
Track drive pump vacuum readings of 10-inches
of mercury or higher are not permissiable except
during cold starts. It is recommended that the
track drive suction filter elements be changed if
the vacuum reading exceeds 7-inches of
mercury at a hydraulic oil temperature of 100°F
(38°C) or higher.
To avoid high track drive pump vacuum
readings in cold weather, change the track drive
pump suction filter elements more frequently.
TRAVEL
It is important that you read about and
understand all operating controls, Cautions,
Warnings, and Dangers before traveling.
To avoid serious injury or death, make certain
that the area around and under the machine is
clear of all personnel and obstructions BEFORE
travelling or working.
Failure to engage all lockup devices before
propelling at travel speed can result in injury to
personnel and/or extensive damage to the
machine.
PROPELLING (TRACK TRAVEL OPERATION)
Before propelling this machine, make certain
that all lockups are in their proper position.
Check that suspension is not locked out (for
machines with optional suspension lockouts).
NOTE: The track drive system is strong
enough to overpower the braking system.
For this reason, ALWAYS NEUTRALIZE THE
TRACK DRIVE SYSTEM SLOWLY BEFORE
APPLYING THE BRAKES.
NOTE: All movements of the pump and
motor control levers carried out in the
following instructions MUST be carried out
SLOWLY and SMOOTHLY.
1. Ensure that engine is at full throttle and the
hydraulics and transmission are warmed up.
Refer to “Engine Startup”, earlier in this section.
2. Engage the 4 speed mechanical transmission by
pushing rocker switch in the desired position as
indicated on the decal. NOTE:
Never shift the
mechanical transmission “on-the-fly”.
3. Release the parking/emergency brake.
4. Adjust the engine speed using engine speed
switch on the control panel.
5. To Accelerate: Lift up the lock ring on the EDC
control lever and slowly move the lever in the
desired direction until the desired speed is
attained.
6. To Decelerate: Lift up the lock ring on the EDC
control lever and slowly move the lever towards
the N or NEUTRAL position. Adjust engine
speed accordingly.
7. To Change Direction: Bring the machine to a
complete stop by moving the EDC controller to
the NEUTRAL position. Accelerate as in Step 5.
NEVER ATTEMPT TO CHANGE DIRECTION OF
MACHINE TRAVEL WITHOUT FIRST BRINGING
THE MACHINE TO A COMPLETE STOP.
