Electrical Hazard Warning

THE MHP AERIAL WORK PLATFORM

IS NOT ELECTRICALLY INSULATED.

If the plat form, booms, or any other con duc tive part of a MHP 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) - AS OUTLINED IN TABLE 1. AND FIGURE 3.,

ON THE NEXT PAGE.

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

If a MHP 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 MHP.

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 MHP un til you are sure the elec tric ity has been turned off.

If a MHP 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 MHP 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 MHP ground con trols when the plat form, booms, or any other con duct ing part of a MHP 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 en er gized.

Per son nel work ing on or near a MHP 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.

■

Work Place Inspection and Practices

Do not use the MHP15/44 as a ground for weld ing. Ground to the work piece.

Be fore the MHP15/44 is used, and dur ing use, check the area in which the MHP15/44 is to be used for pos si ble haz ards such as, but not lim ited to:

●

Drop-offs or holes.

●

Side slopes.

Page 10

1. Safety

DANGER

●

Bumps and floor obstructions.

●

Debris.

●

Overhead obstructions and electrical conductors.

●

Hazardous locations.

●

Inadequate surface and support to withstand all load forces imposed by the aerial platform in all operating configurations.

●

Wind and weather conditions.

●

Presence of unauthorized persons.

●

Other possible unsafe conditions.

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.

Do not en gage in any form of “horse play” or “stunt driv ing” while op er at ing the MHP15/44.

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.

Be fore the MHP15/44 is used, de ter mine the haz ard clas si fi ca tion of any par tic u lar at mo sphere or lo ca tion ac cord ing to ANSI/NFPA 505-1987.

Any MHP15/44 op er ated in a haz ard ous lo ca tion must be ap proved and of the type re quired by ANSI/NFPA 505-1987.

While operating the MHP a recommended safety practice is to have trained and qualified personnel in the immediate work area of the MHP15/44 to:

●

Help in case of an emergency.

●

Operate emergency controls as required.

●

Watch for loss of control by platform operator.

●

Warn the operator of any obstructions or hazards that may not be obvious to them.

●

Watch for soft terrain, sloping surfaces, drop-offs, etc., where stability could be jeopardized.

●

Watch for bystanders and never allow anyone to be under, or to reach through the booms while operating the aerial platform.

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

Do not op er ate an MHP15/44 that is dam aged or not func tion ing prop erly. Do not use the MHP until the ma chine has been re paired by a qual i fied main te nance per son.

Do not op er ate a MHP15/44 that does not have all its de cals and plac ards at tached and leg i ble.

Watch for by stand ers and never al low any one to be un der, or to reach through, the ma chine and its equip ment while op er at ing.

Use the rec om mended trans port de vice when load ing the ma chine.

■

Operation

If you en coun ter any sus pected mal func tion of the ae rial plat form, or any haz ard or po ten tially un safe con di tion re lat ing to ca pac ity, in tended use, or safe op er a tion, cease op er a tion im me di ately and seek as sis tance from man age ment.

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.

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.

page 1 - 2 MHP15/44 – 12459A

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 un til all per son nel are clearly away from the ma chine.

Never cover the floor grat ing or oth er wise ob struct your view be low. Make sure the area be low the plat form is free of per son nel be fore low er ing.

Tipover and Falling Hazards

Operate the MHP only on a firm, flat, level surface capable of withstanding all load forces imposed by the MHP15/44 in all operating conditions.

The MHP can tip over if it becomes unstable. Death or serious injury can result from a tip-over accident. Do not drive or position the MHP platform for elevated use near any drop-ff, hole, slope, soft or uneven ground, or other tip-over hazard.

Do not op er ate the MHP15/44 from a po si tion on trucks, trail ers, rail way cars, float ing ves sels, scaf folds, or sim i lar equip ment un less the ap pli ca tion is ap proved in writ ing by Snor kel.

Care shall be taken to prevent rope, electric cords, and hoses, etc., from becoming entangled in the aerial platform. If the platform or elevating assembly becomes caught, snagged, or otherwise prevented from normal motion by an adjacent structure or other obstacle such that control reversal does not free the platform, remove all personnel from the platform before attempts are made to free the platform using ground controls.

Do not climb on the guardrails or use ladders, planks, or other devices to extend or increase your work position from the platform.

Do not use the MHP as a crane, hoist, or jack,or for any other pur pose other than to po si tion per son nel, their tools, and ma te ri als.

Do not op er ate the MHP15/44 in winds, or wind gusts, of 28 mph, 45kph 12.5 m/s) or more and do not add any thing to the MHP15/44 that will in crease the wind load ing (ban ners, flags, etc.).

General Safety Precautions

Do not mod ify the MHP15/44 in any way.

When parts or com po nents are re placed, they shall be iden ti cal or equiv a lent to orig i nal Snor kel parts or com po nents.

Do not over ride any of the safety fea tures of the MHP15/44.

Hydraulic System Precautions

The hy drau lic sys tem con tains hoses with hy drau lic fluid un der pres sure.

Un der nor mal work ing con di tions it is best not to trans fer from the plat form to an other struc ture or vice versa, un less that is the saf est way to do the job. Each sit u a tion must be judged sep a rately tak ing the work en vi ron ment into ac count. The fol low ing guide lines ap ply:

1. Where possible, place the work platform over a roof or walking structure to do the transfer.

2. Transfer your anchorage from one structure to another before you step across.

3. Remember, you might be departing the work platform to a structure where fall arrest is required.

4. Do not climb over or through the guardrails. Use the platform entrance.

All plat form oc cu pants MUST wear and use fall re straint. At tach fall re straints to the plat form lan yard an chor points.

Do not ex ceed the un re stricted plat form ca pac ity as in di cated on the ca pac ity plac ard at the en trance to the plat form. Do not carry loads from any point out side of the plat form.

Make sure that all pro tec tive guards, cowl ings, and doors are in place and se cure. Be sure the guard rail sys tem, in clud ing the gate, is in place and se cure.

Hydraulic fluid escaping under pressure can have enough force to inject fluid into the flesh. Serious infection or reaction can result if medical treatment is not given immediately. In case of injury by escaping hydraulic fluid, seek medical attention at once.

DO NOT place your hand or any part of your body in front of es cap ing hy drau lic fluid. Use a piece of card board or wood to search for hy drau lic leaks.

Do not at tempt re pairs to hy drau lic sys tems un less you are trained. Re fer to ex pe ri enced re pair per son nel for help.

■

Fire Prevention

Never op er ate your MHP near a flame or spark. Hy drau lic oil and gas o line are flam ma ble and can ex plode.

Engine and Fuel Handling Precautions

Engine exhaust contains carbon monoxide, a poisonous gas that is invisible and odorless. Breathing engine exhaust fumes can cause death or serious illness. Do not run the engine in an enclosed area or indoors without adequate ventilation.

Only re fuel your MHP out doors in a clear area void of gas fumes or spilled gas.

Never re move the fuel cap or re fuel a gas o line en gine while the en gine is run ning or hot. ALWAYS al low the en gine to cool be fore re fu el ing. Never al low fuel to spill on hot ma chine com po nents.

Tighten the fuel tank cap se curely. If the fuel cap is lost, re place it with an ap proved cap from Snor kel. Use of a non-ap proved cap with out proper vent ing may re sult in pres sur iza tion of the tank.

Never use fuel for clean ing pur poses.

For die sel en gines, use the cor rect fuel grade for the op er at ing sea 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.

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 when working near batteries.

ENSURE you use an approved fuel container with appropriate fuel filler nozzle (see picture below)

If the engine dies in ON, the key must be turned to OFF (O) before it will go back to START. Turn the switch to OFF if the platform is to stay in one position for a long time, that will turn the engine off and save fuel.

Emergency Lower: If the engine stops and cannot be restarted, hold the switch down and this will lower the upper and lower booms (not the jib boom). To slew during emergency lower operate emergency lower and slew switches together.

Items 6 through 10 are the plat form mov ing switches. Each is a three po si tion, mo men tary con tact, nor mally OFF switch.

Platform Rotate: (Option) LEFT rotates the platform left. RIGHT rotates the platform right.

Lower Boom: UP raises the lower boom. DOWN lowers the lower boom.

Upper Boom: UP raises the upper boom. DOWN lowers the upper boom.

Jib Boom: UP raises the jib boom. DOWN lowers the jib boom.

10.

Slew: LEFT rotates the entire turntable and boom to the left. RIGHT rotates the entire turntable and boom to the right.

Lift Enable: The platform can only be raised when this light is lit. When this light is not lit the platform will not raise because the outriggers are not properly set.
