1.13 Specific Hazards
1.13.1 Electrical Energy
External Considerations and hazards
When working with the plant, maintain a safe distance from overhead electric lines.
If work is to be carried out close to overhead lines, the working equipment must be
kept well away from them. Check out the prescribed safety distances.
If in Doubt Ask.
If your plant comes into contact with a live wire
xVacate the area
xWarn others against approaching and touching the plant
xReport the incident and have the live wire de-energized.
Machine - Electrical
Work on the electrical system or equipment may only be carried out by a skilled and
qualified electrician or by specially instructed personnel under the control and
supervision of such an electrician and in accordance with applicable electrical
engineering rules.
The power supply to the plants, on which inspection, maintenance and repair work is
to be carried out must be isolated before starting any work, check the de-energised
parts for presence of power and ground or short circuit them in addition to insulating
adjacent live parts and elements.
The electrical equipment of the plant is to be inspected and checked at regular
intervals. Defects such as loose connections or scorched or otherwise damaged
cables must be rectified immediately.
If working on live parts and elements cannot be avoided this must only be carried
out in the presence of a second person, who can cut off the power supply in the
case of danger by actuating the emergency shut off or main power switch. Secure
the working area with a red and white safety chain and a warning sign. Use
insulated tools only.
Use only original fuses with the specified current rating. Switch off the plant
immediately if trouble occurs in the electrical system.
This plant is wired on a negative earth. Always observe correct polarity.
Battery
xAlways disconnect battery leads before carrying out any maintenance to the
electrical system.
xRecharge the battery in a well ventilated area
xThe battery contains sulphuric acid, an electrolyte which can cause severe
burns and produce explosive gases.
xAvoid contact with the skin, eyes or clothing.
xNo Smoking when maintaining Battery.

1.13.2 Gas, Dust, Steam, Smoke and Noise
Always operate internal combustion engines out of doors or in a well ventilated area.
If plant is operated for maintenance purposes in an enclosed area, ensure that there
is sufficient ventilation or provide forced ventilation.
Observe the regulations in force at the respective site.
Dust found on the plant or produced during work on the plant should be removed by
extraction, not blowing.
Dust waste should be dampened, placed in a sealed container and marked, to
ensure safe disposal.
Welding or naked flames
Never carry out welding, flame cutting and grinding work on the plant only if this has
been expressly authorised, as there may be a risk of explosion and fire.
Before carrying out welding, flame cutting and grinding operations, clean the plant
and its surroundings from dust and other inflammable substances and make sure
the premises are adequately ventilated (as there may be a risk of explosion).
Avoid all naked flames in the vicinity of this equipment
Personal Protection
Ensure that the operators are provided with hearing protection of approved pattern
and that these are worn at all times when the plant is operating.

damage. Repair damage immediately. Splashed oil may cause injury and fire.
Always relieve pressure from the hydraulic system before carrying out any kind of
maintenance or adjustment.
Depressurise all system sections and pressure pipes (hydraulic system,
compressed air system) to be removed in accordance with the specific instructions
for the unit concerned before carrying out any repair work.
Hydraulic and compressed air lines must be laid and fitted properly. Ensure that no
connections are interchanged. The fittings, lengths and quality of the hoses must
comply with the technical requirements.
Only fit replacement components of a type recommended by the manufacturer
Always practice extreme cleanliness servicing hydraulic components.
Hydraulic fluid under pressure can penetrate the skin causing serious injury.
If fluid is injected under the skin, it must be surgically removed or gangrene will
result. Get medical help immediately.
Always use a piece of cardboard to check for leaks. Do not use your hand.

2.3 Operation description
Section 3 of this manual provides details of Transport Commissioning and Operation this must be
read and fully understood before operating this equipment.
Material is loaded normally by excavator into the Feeder where the material is transferred
towards the Screenbox,
The material passes over the Screenbox where smaller material will fall through the Top Deck
and onto the Bottom Deck.
The larger material that has stayed on the Top Deck is fed to the Tail Conveyor and is stockpiled
at the rear of the Machine.
The smaller material that has fallen through to the Bottom Deck is transferred either to the L/H
Side Conveyor or falls through to the Fines Conveyors and is stockpiled at either side of the
Machine.

3.3 Machine Starting Sequence
The E-7 is equipped with safety shutdown control panel. With this type of system, built-in switches set to
factory preset limits, operate such that if during operation, either the oil pressure or engine temperature
reaches its preset limit, the system will experience a safety shutdown and turn the engine off.
Caution
If a safety shutdown occurs, the condition causing the engine to shut down must be corrected before
any attempt is made to restart it.
COLD START:- When starting the machine in temperatures of 0oC or below, run the
Screenbox for 15 minutes to allow hydraulic oil to reach working temperature. DO NOT
feed material into machine during this time. DO NOT operate systems contrary to these
instructions
NOTE:- The machine MUST be set up on firm, level ground before being operated. Failure to
comply with this or any other instructions in this manual may cause damage to the machine and may
invalidate any warranty.

3.5 TRACKING (MOVING) PROCEDURE
The operator must be fully trained in the operation of this equipment.
When tracking the operator must be in a position to have an all round view of the
operation, a banks man or marshal should assist where this is not possible.
Ensure the site is clear of non essential personnel. Barrrier the area and post
warning signs where site conditions warrant this.
Tracking must only be carried out on firm flat ground.
Note This equipment must never be tracked on gradients that are more than:-
10 degrees Port to Starboard or 20 degrees Front to Back.
The machine must always be on flat, solid ground when operating in its
normal mode.
When engine is running at low revs the machine can be moved to the desired
location on site by following the procedures in the order listed below:-
1 Remove Mid-Grade Side Conveyor bottom
section locking pins
2 Activate 'L/H Lower Side Conv.
Up/Down' lever to raise the conveyor
bottom section
3 Insert locking pins to
lock bottom section in
raised position
WARNING:- Never try to move the machine without lifting
the Mid-Grade Side Conveyor bottom section FIRST!!!

TRACKING (MOVING) PROCEDURE
4 Activate lever to turn Tracks on
After following the instructions on the previous page, use either the Remote handset or the Hard Wire Drive to move
the machine to the desired position.
NOTE The Remote Handset must be fully recharged at regular intervals. Use the correct instructions for your
controller.
OR
Remote Handset Plug in Hard Wire
Umbilical Socket Hard Wire Handset
WARNING Under NO circumstances try to move the machine when ANY personnel are standing on
the machine.
For safety reasons, it is essential to check all around machine for obstacles or personnel which may
be endangered by moving the machine.
When moving machine, ensure that it is only moved over firm ground suitable for carrying the weight

MACHINE ACROSS EXCESSIVELY SLOPING GROUND.
NOTE
1. When operating the White Remote Handset, the yellow buttons are for forward movement and
the blue ones for reverse. (These correspond to direction indicator stickers on machine)
2. When operating the Hard Wire Handset, the yellow buttons are for forward movement and the
blue ones for reverse. (These correspond to direction indicator stickers on machine)
When the machine is moved to its desired operating position, prepare the E-7 for operation by
following the procedures laid out in the following pages.
