FOUR-WAY JOYSTICK CONTROL LEVER
This lever has five positions, tilt back, tilt forward, lift, lower and hold. Pushing the lever to
the right tilts the lift arms back for loading and tramming. Pulling the lever to the left tilts the
lift arms down for unloading. Pushing the forward lowers the lift arms. Pulling the lever back
raises the lift arms. The lever is spring centred to the hold position.
Two functions may be engaged at the same time by pushing the four-
way joystick control lever at 45° in the direction of the two required
functions.
NO. 1 - TWO-WAY HYDRAULIC CONTROL LEVER
There are two hydraulic two-way control levers fitted to the machine. The first lever closest
to the operator is used to auxiliary hydraulic power take off fitted to the rear of the machine.
This lever has three positions, up, down and hold. The lever is spring centred to the hold
position.
NO. 2 - TWO-WAY HYDRAULIC CONTROL LEVER
The second lever, furthest from the operator, is used to control the winch. This lever has
three positions, up, down and hold. When operating the winch, the down position winches
the rope in and pulling the lever up winds the winch rope out. The lever is spring centred to
the hold position.

Section 6
Pre-Start Procedure
Walk around the machine:
1. Check condition of all tyres. Inspect for sidewall cuts, tread cuts and separation.
2. Look for damaged or missing wheel nuts and studs.
3. Check condition of tyre protection chains if fitted for adjustment, irregular pattern,
wear and breaks.
4. Check for loose wheel nuts.
5. Guards and covers are in place and secure.
6. Missing or loose bolts.
7. Oil leaks.
8. Hose damage.
Normal correct tension is when the machine rolls to a stop (not under brakes) and the TPC
wear links at the bottom of the wheel are just falling away from the tyre.
5 mm to 20 mm would be considered as correct operating range.
Always use the specified lubricant for the application and the regions
seasonal temperatures. (See Section 21).
Never start or operate the machine if the electronic shutdown system
has been bypassed, report to service personnel.
Always ensure the machine is correctly isolated before undertaking
any tasks.

Section 7
Engine Starting Procedure
Always sound the horn and make sure the area around the machine,
especially between the front and rear frames, is clear before starting
the engine. Never attempt to start an engine without first knowing how
to shut it off.
Do not start the engine if machine is tagged out or safety notice is
affixed.
If the Emergency Intake Shut Off valve has been operated, restarting
of the engine should be done in compliance with the Manager’s Rules.
ONLY RESTART THE ENGINE AFTER VERIFYING THAT THERE HAS
BEEN NO INGRESS OF WATER FROM EXHAUST CONDITIONER INTO
THE ENGINE.
THIS IS TO BE VERIFIED BY SERVICE PERSONNEL PRIOR TO
ATTEMPTING ENGINE START.
1. Turn the main air isolation valve, located in the engine compartment to the on
position.
2. Enter the operator’s compartment and close and latch the door.
3. Place the transmission directional control lever in the neutral position.
4. Make sure the park brake is applied. Check the air pressure gauge. If the start
pressure is below 275 kPa (39 psi) the engine may not start. If the air pressure is
below 275 kPa (39 psi), recharge the air receiver up to maximum 827 kPa (120 psi).
5. Turn the on/off toggle switch to the on position.
The electronic shutdown system display LEDs will not activate if the
air pressure is below 275 kPa
6. Wait for the run solenoid display LED to go off (approximately 30 seconds).
7. Hold the accelerator pedal approximately ⅓ to ½ open.
8. Press the engine start button and release it when the engine has fired.
9. Check the charge failure and engine oil pressure display LEDs have gone out.
10. Carry out post start checks and operate machine normally.
See Section 20 - Operating Electronic Shutdown System
As soon as the engine starts, check all gauges and indicators to ensure that all systems are
functioning correctly. Always let the engine warm up slowly. Never load up a cold engine.
Do not engage the starter motor when the flywheel is moving.

Section 17
Towing with the Machine
The transmission will not hold the machine when the spring applied
park brakes are bypassed by the Porta-Power pressure.
Maximum towing speed is 3 kph.
1. Ensure the machine is parked and isolated prior to connecting the trailer or load, park
brake on.
2. Attach the load to the rear tow hitch, ensure tow pin is secure.
3. The trailer or load should be secured by 2 x 16000 kg safety chains in a straight line
pull in addition to a rated draw bar for the task.
4. Both chains must be used and adjusted to ensure an even pull.
5. Both chains have a combined loading of 32000 kg in a straight line.
6. Both chains must be used for maximum tractive effort pull.
7. Ensure all connections on the towed piece are in good condition and rated for the
maximum pull.
8. Ensure all holding devices and hitches are in good condition and rated for the
maximum pull before connecting the machine.
9. Always ensure that the trailer and load are secure before towing, and prior to
releasing the park brake.
10. Travel at a speed that is suitable to conditions and load.
11. Ensure trailer or load has wheels chocked prior to removal from the machine.
Always connect the trailer or load before releasing the park brakes.
Make sure the park brake is reapplied before the towing machine is
disconnected
For towing braked trailer masses consult Bucyrus.
Failure to comply to these procedures may result in serious personal
injury or damage to the equipment.
