Operation Manual
ALWAYS be aware of the impact of the payload on the visibility available to the
operator. The recommended maximum speed when loaded is 10 km/h,
however, the impact of the payload on the operator’s field of vision must
be considered when operating the machine with payload. Drive to the
conditions.
NEVER operate the machine under unsecured roof.
Keep your machine clean. A clean machine makes for a safer machine.
No diesel engine should be operated underground if it is smoky, running unevenly, or
if the exhaust system is leaking or not in good condition.
In areas where auxiliary ventilation is used, the operator should make sure fans are
operating before starting the machine.
The engine shall not for any reason be left running unattended underground.
The engine should not be shutdown from full load and must be allowed to idle for a
few minutes before stopping.
Never operate a machine that you feel is mechanically unsafe.
Specific pedestrian danger areas exist as outlined on the following
illustration while machine is operating. Do not allow personnel to
enter these exclusions zones while in operation. If access is required
to these exclusion zones communication must be made with the
operator and appropriate isolation (Section 5) and hazard/risk
assessments completed as required.

Operation Manual
TRANSMISSION GEAR CONTROL LEVER
The transmission gear control lever has four positions, first, second, third and fourth.
Shifting from one range to another can be made at any time conditions permitting.
Momentarily decrease engine revs when selecting a higher gear. Momentarily increase
engine revs when selecting a lower gear.
The transmission in the machine is modulated. This prevents severe
shocks being transmitted through the drive train when the
transmission direction is changed..
TRANSMISSION DIRECTIONAL CONTROL LEVER
A directional control lever controls the transmission. This lever has three positions, forward,
neutral and reverse. The engine should be at low idle when the transmission is shifted from
the neutral position to either forward or reverse direction.
The transmission must be placed in the neutral position for the starter
motor to engage when starting the engine.
If the engine starts when the transmission is not in neutral, the
machine should be tagged out of service until the problem is rectified.

Operation Manual
HYDRAULIC ISOLATION
To isolate the hydraulic system perform the following procedure:
1. Ensure the area is clear of any obstruction and area is fit for carrying out safe
operation and maintenance.
2. Lower the lift arms to the ground, shutdown the engine, fit a danger tag to the on/off
toggle switch, connect the articulation lock and chock the wheels.
3. Depress the attachment quick connects button located in the operator's compartment.
This will remove any residual pressure stored in the PTO lines.
4. Observe both steering and brake pressure gauges located in the operator's
compartment. The hydraulic system features a steering and brake accumulator. The
brake/steer control manifold bleeds accumulator pressure over time, once the
machine has been shutdown. To aid in the removal of residual pressure, prior to
exiting the operator’s compartment and with the door closed turn the steering wheel
from side to side and observe the steering accumulator pressure gauge return to
zero.
5. Remove hydraulic tank pre-charge pressure (50 kPa) by cracking the hydraulic tank
filler cap.
Serious injuries can occur from hydraulic oil under pressure. Ensure
all loads are mechanically supported before removal of any hydraulic
lines. Always assume there is hydraulic pressure in hydraulic lines or
components unless it has been isolated by yourself. Hydraulic fluid
may be hot. Wear personal protective equipment such as safety
glasses, long sleeve shirt and gloves.
Crack hose end fitting (if pressure is present in line tighten fitting and
remove pressure as above) but do not remove till any residual
pressure is removed.
Ensure the machine is clear of pedestrians and equipment when
undertaking this procedures.

Check the fuel level:
1. Gauge fitted to the fuel tank.
2. Check the filler cap is secure, not damaged and seal is in place.
3. Ensure the filler cap seal is in place.
To fill the fuel tank:
1. Ensure the area is clear of any obstruction and the area is fit for carrying out safe
operation and maintenance.
2. Locate the fuel tank filler cap on the driver’s side of the machine.
3. Release the filler cap lock by pulling the Lock away from the centre of the cap.
4. Lift the filler cap and insert the fuel filler/nozzle and fill the tank.
Do not allow the fuel tank to overflow as diesel fuel is a fire hazard.
Clean any excess fuel away immediately and dispose of in an
appropriate manner.
5. Once the tank is full, close the fuel tank filler cap and allow the filler cap lock to spring
into position over the cap.
6. The fuel level gauge will indicate the tank is full.
Always ensure the machine is correctly isolated before undertaking
any tasks.
Do not operate the machine with the fuel level below empty level on
the fuel tank. It is a recommended procedure to fill the fuel tanks at the
end of each shift to drive out moisture laden air and to prevent
condensation. Do not overfill the tank. Use caution when refuelling an
engine. Ensure appropriate PPE is worn.
Always use quality fuel to the specification shown in Section 21 - Fluid
Specification Table.
