1. GEAR LEVER: Four gears are selectable for the required ground speeds in both forward or re- verse travel.

2. TRANSMISSION DISCONNECT BUTTON: Prior to changing gear depress and hold down this switch which disengages transmission drive, se- lect the required gear with the gear lever and re- lease the switch to re-engage drive.

3. LOADER ATTACHMENT CONTROL LEVER 4. MECHANICAL DIFFERENTIAL LOCK PEDAL:

Depressing this pedal will lock both rear wheels together giving equal drive and will disengage when wheel torque equalizes or foot brakes are applied.

5. TRANSMISSION POWERSHUTTLE DIREC- TION LEVER: Movement of this lever from the neutral position will engage forward or rearward travel.

NOTE: in reverse gear an audible alarm device sounds.

Transmission

The transmission is fully synchronised providing four forward and four reverse speeds allowing gear ratio changes on the move. A torque converter is used to connect the engine to the transmission and the col- umn mounted powershuttle lever (4) enables shifts between forward and reverse travel without disen- gaging gear ratios.

A device for “transmission disconnect” is activated by pushing button (2), placed on the gear shift lever (1) or by pushing button (5), placed on the loader control lever (3).

WARNING

Always apply the parking brake whenever the ma- chine is parked as the machine is free to roll even though the transmission gearshift lever and power reversing lever may be “In Gear” and the engine is turned “OFF”.

Gear Shift Lever

The single gearshift lever (1) is used to select any one of the four gear ratios. The transmission discon- nect button (2) is depressed and held as the lever is shifted from one gear to another and then released to re-connect transmission drive.

Forward/Reverse Powershuttle Lever

To select FORWARD travel, engage the required gear ratio with the gearshift lever, then with the en- gine idling lift the powershuttle lever from the neutral lock position (1) and move to the forward position (2).

Use the foot accelerator to control the engine and ground speed.

To reverse the direction of travel, reduce engine speed and move the power reversing from neutral lock position (1) and rearwards (3) for reverse travel an audible alarm device sounds.

IMPORTANT: the powershuttle lever is equipped with a neutral lock to prevent inadvertent engage- ment of the transmission. With this design the power reversing lever moves through a “T” slot for the for- ward and reverse positions.

IMPORTANT: when operating in low ambient tem- peratures with cold transmission oil, allow the oil to warm up before attempting to shift the powershuttle lever. The transmission can be shifted normally after the oil warms up.

NOTE: the horn will sound if the powershuttle lever is operated (forward or reverse) with the handbrake engaged.

NOTE: the powershuttle lever can be shifted at any engine speed, however, for safe, smooth operation the engine speed should be reduced to approximate- ly 1200 rev/min.

This action is easily controlled by using the foot ac- celerator to control engine and ground speed.

Transmission Disconnect

The 4x4 transmission provides for easy upward and downward gear ratio changes on the move. Howev- er, as a clutch is not used between the engine and transmission, the power flow from the engine to the transmission must be interrupted to shift from one gear ratio to another. This is accomplished by using a transmission disconnect (dump) button.

The finger operated button (2) on the main gearshift lever knob (1) is easy to operate.

WARNING

To avoid personal injury do not use the disconnect switch control to coast down hill. Excessive speed may cause loss of control, personal injury to a by- stander or failure of the transmission.

To make upward gear ratio changes simply depress and hold the button (2) on the gearshift lever (1), while moving the lever from one gear ratio to anoth- er. When the desired gear ratio has been selected release the button and allow the unit to gain engine speed and ground speed. If another higher ratio is re- quired repeat the procedure.

IMPORTANT: to avoid possible damage to the transmission hydraulic clutches never use the dis- connect switch for inching the machine forward.

Inching the machine forward with the button will cause the clutches to slip excessively and overheat.

To make downward gear ratio changes or reduce ground speed, simply lower the engine speed, de- press and hold the gearshift lever button and down- shift the transmission.

When the desired gear ratio has been selected re- lease the button and adjust the engine speed to suit ground speed required.

Operating the machine in a too high gear or under a too heavy load will cause the torque converter to slip excessively and overheat. If the machine is over- loaded, the engine speed will not exceed a range of 1800-2200 rev/min at maximum accelerator and the torque converter will “stall” bringing the machine to a complete stop.

If “stall” does occur, there is still sufficient engine power to operate the loader however, to prevent the transmission from overheating, either reduce the load on the machine or select a lower gear ratio.

IMPORTANT: operating at a “stall” for more than 20 seconds can cause the transmission to overheat and can possibly damage the transmission. If the trans- mission overheats, the needle (1) reaches the red field. Shift both the power reversing and gearshift le- vers to neutral. Let the engine run idle (1000 rpm) un- til transmission oil cools down enough to have the needle (1) return to correct position. Once the needle is returned to its position, all operations can be re- sumed.
