Electrical Hazard Warning

THE MHP14AT / MHP13AT AERIAL WORK PLATFORM, IN STANDARD

CONFIGURATION, IS NOT ELECTRICALLY INSULATED.

If the plat form, booms, or any other con duc tive part of a MHP14AT / MHP13AT con tacts a high-volt age elec tri cal con duc tor, the re sult can be SERIOUS INJURY or DEATH for per sons on or near the ma chine.

GO NO CLOSER THAN THE MINIMUM SAFE APPROACH DISTANCES

(M.S.A.D) - SEE BELOW.

Be sure to al low for sag and sway in the wires and the work plat form.

If a MHP14AT / MHP13AT co mes in con tact with a live elec tri cal con duc tor, the en tire ma chine can be charged.

If that hap pens, you should re main on the ma chine and not con tact any other struc ture or ob ject within reach. That in cludes the ground, ad ja cent build ings, poles, and any ob ject not a part of the MHP14AT / MHP13AT.

Such con tact could make your body a con duc tor to the other ob ject cre at ing an elec tri cal shock haz ard re sult ing in SERIOUS INJURY or DEATH.

DO NOT at tempt to en ter or leave the MHP14AT / MHP13AT un til you are sure the elec tric ity has been turned off.

If a MHP14AT / MHP13AT is in con tact with a live con duc tor, the plat form op er a tor MUST warn oth ers on the ground in the vi cin ity of the MHP14AT / MHP13AT to STAY AWAY from the ma chine, since their bod ies can also form a path for elec tric ity to ground thus cre at ing an elec tri cal shock haz ard with pos si ble

ELECTROCUTION and DEATH.

DO NOT at tempt to op er ate the MHP14AT / MHP13AT ground con trols when the plat form, booms, or any

other con duct ing part of a MHP14AT / MHP13AT is in con tact with elec tri cal wires or if there is an im me di ate dan ger of such con tact.

Re gard all con duc tors as energised.

Per son nel work ing on or near a MHP14AT / MHP13AT must be con tin u ously aware of elec tri cal haz ards, rec og niz ing that SERIOUS INJURY or DEATH can re sult if con tact with an elec tri cal wire does oc cur.

1. Safety

DANGER

Pinch points may exist between moving components. Death or serious injury can result from becoming trapped between components, buildings, structures, or other obstacles. Make sure there is sufficient clearance around the machine before moving the chassis, booms, or platform. Allow sufficient room and time to stop movement to avoid contact with structures or other hazards.

Keep ground per son nel from un der the plat form when the plat form is raised.

Se cure all ac ces so ries, con tain ers, tools, and other ma te ri als in the plat form to pre vent them from ac ci den tally fall ing or be ing kicked off the plat form.

Al ways look in the di rec tion of travel. Drive with care and at speeds com pat i ble with the work-place con di tions. Use cau tion when driv ing over rough ground, on slopes, and when turn ing.

Use three points of sup port when get ting on or off the plat form (two hands and one foot or a sim i lar set of points). Keep the plat form clean.

Main tain a firm foot ing on the plat form floor. Op er ate the con trols slowly and de lib er ately to avoid jerky and er ratic op er a tion. Al ways stop the con trols in neu tral be fore go ing in the op po site di rec tion.

Do not dis mount while the plat form is in mo tion or jump off the ma chine.

Do not start until all personnel are clearly away from the machine.

Never cover the floor grating or otherwise obstruct your view below. Make sure the area below the platform is free of personnel before lowering.

■

Tipover and Falling Hazards

Operate the MHP only on a firm, flat, level surface capable of withstanding all load forces imposed by the MHP14AT / MHP13AT in all operating conditions.

Do not engage in any form of “horseplay” or “stunt driving” while operating the MHP14AT / MHP13AT.

Do not per mit rid ers on the ma chine any place other than on the plat form.

Re move all loose ob jects stored in or on the ma chine, par tic u larly in the plat form. Re move all ob jects which do not be long in or on the ma chine.

Never steady the plat form by po si tion ing it against an other plat form.

Do not op er ate an MHP14AT / MHP13AT that is dam aged or not func tion ing prop erly. Do not use the MHP un til the ma chine has been re paired by a qual i fied main te nance per son.

Batteries

Charge bat ter ies in a well ven ti lated area free of flame, sparks, or other haz ards that might cause fire or ex plo sion.

Batteries give off hydrogen and oxygen that can combine explosively. Death or serious injury can result from a chemical explosion. Do not smoke or permit open flames or sparks when checking batteries.

This is to al low the unit to be op er ated by unlicensed op er a tors in ac cor dance with Aus tra -

lian leg is la tion.

An Australian op er a tor MUST hold a WP

Cer tif i cate of Com pe tency in or der to

op er ate the ma chine at heights in ex cess of

11m.

Height Restriction on MHP13AT

The MHP13AT (in stan dard mode) is fit ted with a restrictor in the upper hy drau lic lift cyl in der to keep the plat form to a max i mum height of 10.9m.

■

10.9 Metre Restriction Kit

Ma chines that are built for the Aus tra lian mar ket may be fit ted with a 10.9m re stric tion kit.

This kit which can be fit ted to the MHP14AT is fit ted to re strict the max i mum height to the plat form floor at 10.9 m from the ground.

Note:

See the Options chapter page 6 for details concerning this kit.

Battery acid can damage the skin and eyes. Serious infection or reaction can result if medical treatment is not given immediately. Wear face and eye protection, rubber gloves and protective clothing when working near batteries.

If acid contacts your eyes, flush immediately with clear water and get medical attention. If acid contacts your skin, wash off immediately with clear water.

■

Height Restriction

The height restrictor fitted to the standard MHP13AT, is not the same device as the

10.9m restriction kit, although both of these devices achieve the same result of restricting the maximum height of the platform to 10.9m from the ground.

■

Safety Decals and Placards

There are a num ber of safety de cals and plac ards on the MHP14AT / MHP13AT. Their lo ca tions and de scrip tions are shown in this sec tion on the fol low ing pages. Take time to study them.

Electrical Circuit Protection

There is only one (1) fuse, on a stan dard MHP14AT / MHP13AT, that is ac ces si ble to the op er a tor. Its pur pose is to pro tect the elec tri cal cir cuits from elec tri cal over loads. When the fuse blows re place it with an iden ti cally rated fuse. If the fuse blows a sec ond time, take the MHP14AT / MHP13AT out of ser vice and re fer the prob lem to a qual i fied trained ser vice tech ni cian for re pair.

If the prob lem per sists call a trained ser vice tech ni cian.

Operating Procedures

This chap ter ex plains how to prop erly start and op er ate an MHP14AT / MHP13AT. Read and un der stand all the pre vi ous chap ters in this man ual be fore you be gin to op er ate an MHP14AT / MHP13AT.

Do not leave the MHP14AT / MHP13AT engine running if you are sandblasting. Sand drawn into the air intake can erode engine parts.

■

Control Stations

An MHP14AT / MHP13AT can be op er ated from the ground con trol box or from the plat form con trol box. There are ba si cally two dif fer ences be tween ground con trol and plat form con trol op er a tions, both are safety re lated:

1. The ground control station can override the platform control station at any time. If a person operating the machine from the platform becomes incapacitated, a person on the ground can always take over machine control.

■

Emergency Stopping

Figure 8.1 - Ground Con trol Box Emer gency

Stop Switch Lo ca tion.

2. The stabilisers can only be selected from the ground control station and only when the booms are in the stowed position.

The MHP14AT / MHP13AT is not Electrically Insulated in its standard form.

Death or Serious Injury to operating personnel, can occur if the machine should come into contact with energised electrical wires during operation.

Figure 8.2 - Platform Control Box Emergency

Stop Switch Location.

NOTE

For a complete discussion of the Emergency Stop switches, see “Controls” chapter 6, and

"Emergency Operation" chapter 9 in this manual.

DO NOT attempt to operate the MHP14AT / MHP13AT ground controls if the platform, booms, or any other conducting part of an MHP14AT / MHP13AT is in contact with energised electrical wires or if there is an immediate danger of such contact.

■

Operation Considerations

To use this chapter, first decide whether you will be starting and operating the MHP14AT / MHP13AT from the ground control box or the platform control box.

NOTE

See the "Electrical Hazard" section, in this manual for a complete explanation of the hazards concerning electricity.

■

Emergency Stopping

To stop an MHP14AT / MHP13AT, press the red EMERGENCY STOP but ton in, on ei ther the ground con trol box or the plat form con trol box

MHP14AT & MHP13AT – 13618-1 Rev B page 8 - 1

■

Stabiliser Operation

NOTE: All Stabiliser Operations

The stabilisers will only function when the platform is fully lowered and the booms are stowed. Once the booms are raised the stabilisers will not operate.

Once the platform is raised the stabilisers cannot be set or adjusted.

Page 50

8. Operation

WARNING

DANGER

Before operating the stabilisers check to see that the ground conditions under the four stabiliser pads is firm, stable and unobstructed.

If the platform is up and the ground compresses unevenly under different stabiliser pads the MHP might fall over causing serious injury or death. Check the level bubble frequently during operation. If any movement of the bubble occurs, immediately lower the platform and readjust the stabilisers to re-center the bubble in the ring.

When us ing the sta bi lis ers al ways check that all four are firmly on the ground and that they are clear of man hole cov ers, drains, etc., which may col lapse. If the ground is at all soft, steel plates at least 300mm x 300mm x 6mm should be placed un der the feet to spread the weight.

Death or serious injury can result if an MHP tips over. Do not use the stabilisers to gain extra working height, they are not designed for that purpose. At least one of the stabilisers should raise the MHP above the ground - use the other three to level the MHP as necessary.

NOTE: Operating the Stabilisers

Before you can operate the stabilisers you need to start the engine. See "Starting From Ground Control Box" on page 3.

❑ Using the manual stabiliser valves

Ensure the Boom/Stabiliser Switch (item  on the ground control box) (see Figure 8.7) is set to stabiliser.

Figure 8.3

Lower the rear stabilisers and level the ma chine us ing the level bub ble (see Fig ure 8.4) ad ja cent to the con trol le vers.

Figure 8.4

When levelling the machine in either the manual or automatic mode care is required to ensure that all the foot plates are firmly on the ground, the machine is level and the lift enable light is on before entering the platform.

Activate the stabilisers with the valve le vers (down wards). (see Fig ure 8.3)

NOTE:

Ensure that the front stabilisers are lowered first to prevent damage to the jockey wheel.

page 8 - 2 Rev B MHP14AT & MHP13AT – 13618-1

❑ Raising the manually operated stabilisers

Raising the sta bi lis ers is the re verse of set ting the sta bi lis ers.

En sure that the Boom/Sta bi liser Switch is is set to sta bi liser.

Raise the stabilisers by activating the in di vid ual valve le vers (up wards).

NOTE:

Ensure that the rear stabilisers are raised first to prevent damage to the jockey wheel.

Bi-Energy, Petrol/Diesel / 24V DC

There are various Bi-En ergy op tions avail able for the MHP14AT / MHP13AT. The fol low ing describes the Petrol/Die sel / 24V op tion.

This con sists of a com bi na tion of both a gas o line or die sel en gine and a 24V DC mo tor to give a Bi-en ergy op tion.

Spe cif i cally a 24V DC mo tor is mounted on the col umn un der the left hand side cover. This pro vides an al ter na tive power source to the gas o line or diesel en gine.

The DC mo tor is pow ered by four "Deep Cy cle Trac tion Bat ter ies" mounted 2 each side of the column and an au to matic bat tery charger that is also mounted on the column.

11. Options

❑ DC motor battery switch

In or der to op er ate the DC mo tor the 24V DC bat tery iso la tor switch, mounted at the cen tre rear of the column, will also need to be switched on (see Fig ure 11.3).

Figure 11.3 - DC Motor Battery Isolate Switch

❑ DC motor

The DC mo tor is mounted un der the left hand side cover (see Fig ure 11.1).

Figure 11.1 - DC Motor

❑ DC motor operation

A Fuel / Elec tric switch is used to se lect ei ther the gas o line/die sel en gine or the DC mo tor. This switch is mounted on the front of the lower con trol box (see Fig ure 11.2.1).

Note - 24V DC Battery Switch

When operating the gasoline/diesel engine the 24V DC battery switch should be turned to the "off" position.

❑ Setting the manual stabilisers

In order for the stabilisers to function an additional switch (see Figure 11.4) needs to be operated.

This switch, mounted adjacent to the stabiliser valve levers, must be held on in the STABILISER ENABLED  position while the individual stabiliser valves are operated.

When released it will automatically return to the STABILISER DISABLED  position

Figure 11.4 - Stabiliser Enable Switch

Note: - Stabiliser Enable Switch

This switch is ONLY fitted to units that have manual stabiliser valve levers.

❑ Setting the automatic stabilisers

DANGER

❑ Operation

Once the DC mode is se lected the mo tor will then power all the func tions in the nor mal man ner, (ex clud ing the man ual sta bi liser op er a tion de scribed above).

The only dif fer ence is that the DC mo tor will only run when a func tion is se lected e.g. rais ing a boom.

❑ Batteries

Since the Bi-Energy MHP is pow ered by "Deep Cy cle Trac tion Bat ter ies" par tic u lar at ten tion should be paid to the bat ter ies on-board charger to en sure proper op er a tion.

The bat ter ies are mounted at each side of the col umn (see Fig ures 11.5 and 11.6).

Lead-acid batteries contain sulphuric acid which will damage eyes or skin on contact.

When working around batteries, ALWAYS wear a face shield to avoid acid in the eyes.

If acid contacts eyes, flush immediately with clear water and get medical attention.

Wear rubber gloves and protective clothing to keep acid off the skin, if acid contacts the skin, wash off immediately with clear water.

Lead-acid batteries produce flammable and explosive gasses. NEVER allow smoking, flames or sparks around batteries.

❑ Battery charger

The Bi-en ergy MHP is fit ted with an on-board charger (see Fig ure 11.7). The charger will com pletely re-charge the bat ter ies and au to mat i cally turn off af ter the cy cle is com pleted.

Figure 11.5 - Two DC Motor Batteries

(Lower Control Box Side)

Figure 11.6 - Two DC Motor Batteries

(Petrol/Diesel Engine Side)

The side covers must be removed/raised whilst charging to allow gasses to escape.

Figure 11.7 - On-Board Battery Charger

The bat tery charger is fit ted with an "in ter lock". This means that dur ing the charg ing cy cle all func tions on the ma chine are in op er a tive and will re main so un til the charger unit is switched off.

The charg ing cy cle may last from 1 to 12 hours de pend ing on the state of the bat ter ies.

If the charg ing cy cle should ex ceed 16 hours (in di cat ing a fault) the charger will au to mat i cally shut down and the bat ter ies should be checked.

The in let for con nec tion of mains power to the charger is mounted un der the left hand side cover and can be ac cessed with the side cover re moved (see Fig ure 11.8).

Bi-Energy, Petrol/Diesel / 240V AC

An other Bi-En ergy op tion avail able for the MHP14AT / MHP13AT is the 240V AC / Petrol/Die sel op tion de scribed below.

This con sists of a com bi na tion of both a gas o line or die sel en gine and a 240V AC mo tor to give a Bi-en ergy op tion.

Spe cif i cally a 240V AC mo tor is mounted on the col umn un der the left hand side cover. This pro vides an al ter na tive power source to the gas o line or die sel en gine.

The AC mo tor is pow ered from an ex ter nal AC power source

❑ AC motor

The AC mo tor is mounted un der the left hand side cover (see Fig ure 11.9).

DO ENSURE the side covers are removed/raised during the charging process to allow gasses to escape.

❑ Batteries - general maintenance

Al ways keep the bat ter ies clean, free of dirt and cor ro sion. A film on top of the bat tery can ac cel er ate dis charge.

Cold re duces bat tery ca pac ity and re tards charg ing. Heat in creases wa ter us age and can (in ex treme cir cum stances) re sult in over charg ing.

Use dis tilled wa ter to re fill the bat ter ies. Avoid wa ter con tain ing me tal lic sol ids such as iron.

❑ Batteries - charging

Fully re charge the bat ter ies, im me di ately af ter use. One charg ing cy cle per day is pre ferred. Fully charged bat ter ies per form best. The deeper the dis charge, the fewer num ber of cy cles a bat tery will de liver. Deep dis charges de te ri o rate the bat tery quicker than shal low cy cles.

An overly dis charged bat tery may need to be cy cled a few times be fore it can fully re cover. If a bat tery be gins to heat be fore be com ing fully charged, it may be nec es sary to re charge and dis charge the bat tery a few times.
