ADDITIONAL PRELIMINARY INSTRUCTIONS
PRECAUTIONARY INSTRUCTIONS FOR NEUTRAL STARTING AND REVERSING.
IMPORTANT: IMPORTANT: Check as follows before operating the machine.
CHECK NEUTRAL START CIRCUIT Ensure the area around the machine is free. The parking brake must be fully disengaged disengaged Press the “I “I NCHING NCHING ” ” pedal all the way down Move transmission control lever to forward position. Turn starter key to “START”. The gears and diagnosis display will show COD 041. Move control lever to neutral, then back on to forward, COD 044 will be shown. Listen: The starter motor should not crank.
CONDITIONS FOR STARTING.
1) With the gear selector lever in forward and parking brake engaged, turn the switch key to “START”, to start the engine.
2) With the gear selector lever in neutral and parking brake engaged, turn the switch key “START”, to start the engine.
3) With the gear selector lever in neutral and parking brake engaged, turn the switch key to “START”, to start the engine.
CHECK THE REVERSING ALARM
Ensure the area around the machine is free. Engage parking brake. Press the “I “I NCHING NCHING ” ” control pedal all the way down. Ensure the area around the machine is free. Engage parking brake. Press the “I “I NCHING NCHING ” ” control pedal all the way down. Move transmission control lever to 1st gear reverse. Check that the reversing alarm sounds.
STOPPING AND STARTING THE MACHINE WITH THE DISPLAY SHOWING A GEAR ABOVE 4th GEAR
Stop using the “I “I NCHING NCHING ” ” pedal. The machine will always select 2nd gear to start. For grading work or moderate cutting, start in 4th gear and gradually shift up if conditions permit. For steep grading work or overload, shift down and proceed. STARTING THE MACHINE Move the gear selector lever to the gear position desired, which will be shown on the display, then drive the machine. The “I “I NCHING NCHING ” ” pedal may be used similarly to a mechanical clutch. Most operators will perceive in this a very natural operation. INCHING PEDAL Use when starting or stopping the machine. Use in finish work requiring a “sliding clutch” for very low speeds. ENGINE STARTING The transmission must be in “neutral” before starting the engine Do not either abruptly depress or release the “I “I NCHING NCHING ” ” pedal to force machine movement. SHIFTING DOWN While the transmission has a a gearshifting protection system, check the tachometer and the speedometer and do not allow engine revs to go below 1700 rpm. Shift down one gear at a time. Change gears without using the “I “I NCHING NCHING ” ” pedal. SHIFTING UP Shift up normally as speed, grading and traction conditions allow. Change gears without using the “I “I NCHING NCHING ” ” pedal. CHANGING GEARS WHILE GOING DOWN STEEP SLOPES During transport, while going down short, steep slopes, the engine can be cranked from the ground by the tires. To keep speeds high, it would be necessary to shift up to protect the engine while braking. Normally, the safe, recommended procedure is to go down slowly using a low gear in combination with the brakes, particularly for long distances.
ADDITIONAL PRELIMINARY INSTRUCTIONS
CHANGING GEARS, FORWARD TO REVERSE, REVERSE TO FOWARD
The operator may do these gear changes as required by working conditions. The transmission will automatically select the most appropriate gear in the opposite direction, this is done with mechanical shock protection.
PARKING BRAKE
The transmission will not engage any gear with the parking brake engaged.
1- Operate the unit at a moderate load during the first 50 hours. Efficient operation is with engine coolant temperature in the GREEN zone of the gauge. Engine operation at a coolant temperature lower than this limit will cause incomplete combustion, higher fuel consumption, loss of power and dirt buildup inside the engine. “Inching” control pedal ................... (See page 29) Transmission control lever ............... (See page 31) Switch key ..................................... (See page 33)
a- Replace transmission oil filter element.
RUN-IN PERIODS
WARNING
Never lubricate, repair or adjust the machine with the engine running.
2 - Inspect the entire machine after the first 10 operating hours. Tighten all loose bolts and other controls. Also check the hydraulic and electrical systems. After the first 50 hours of operation with a new machine, or after major repairs, carry out the following procedures: WARNING
Pressurized fluid. Turn cap slowly to relieve pressure, prior to removing the cap.
b- Replace hydraulic oil filter elemento. c- Check ROPS attachment bolts.
WARNING
Protection provided by the ROPS type frame may suffer if modified or damaged.
d- Check tandem wheel nuts. e- Check wheel attaching nuts.
HAND SIGNALS
It is recommended that both you and the signalman use hand signals to communicate. Before starting work, ensure both of you understand the signals that will be given.
