Electrical Hazard

SR ELEVATING WORK PLATFORMS

ARE NOT ELECTRICALLY INSULATED.

If the plat form, scis sors arm as sem bly, or any other con duc tive part of an SR con tacts a high-voltage 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 an SR 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 SR.

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

If an SR 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 SR 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 SR ground con trols when the plat form, scis sors arm as sem bly, or any other con duct ing part of the SR 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 an SR 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.

Tipover and Falling Hazards

Op er ate the SR only on a firm, flat, level sur face ca pa ble of with stand ing all load forces im posed by the SR3370 / SR2770 in all op er at ing con di tions.

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

Do not op er ate the SR3370 / SR2770 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 Snorkel.

Care shall be taken to pre vent rope, elec tric cords, and hoses, etc., from be com ing en tan gled in the ae rial plat form. If the plat form or el e vat ing as sem bly be comes caught, snagged, or oth er wise pre vented from nor mal mo tion by an ad ja cent struc ture or other ob sta cle such that con trol re ver sal does not free the plat form, re move all per son nel from the plat form be fore at tempts are made to free the platform using ground controls.

Do not climb on the guard rails or use lad ders, planks, or other de vices to ex tend or in crease your work po si tion from the plat form.

Do not use the SR 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 SR3370 / SR2770 in winds, or wind gusts, of 28 mph, 45kph 12.5 m/s) or more and do not add any thing to the SR3370 / SR2770 that will in crease the wind load ing (ban ners, flags, etc.).

General Safety Precautions

Do not mod ify the SR3370 / SR2770 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 SR3370 / SR2770.

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 guidelines apply:

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 platform.

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 SR 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

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.

The HOURS gauge is ba si cally an elec tric clock. It ac cu mu lates time only when the en gine is run ning. The HOURS gauge can not be re set. An SR-qual i fied ser vice tech ni cian uses it to tell when it is time for the pe ri odic main te nance listed in the Main te nance Manual.

Bubble Level

Figure 4.7 - Bubble Level

A bub ble level is lo cated on the plat form side rail, be low the plat form con trol box. Watch the bub ble level while you set the sta bi lis ers man u ally. Lower the sta bi lis ers, one at a time, just enough to cen ter the bub ble in the cir cle on top of the gauge. When the bub ble is cen tered the plat form is level and can safely be raised.

Fuel Level (option)

Figure 4.6 - Fuel Level Gauge

LPG tanks have two fuel gauges on top. One mea sures cor rectly when the tank is stand ing on end (VERTICAL) € the other mea sures cor rectly when the tank is lay ing down (HORIZONTAL) •. Both read in frac tions-of-a-full-tank. (see Fig ure 4.6).

NOTE: LPG fuel installations are usually fitted post

production and may vary from machine to machine. It is the operator’s responsibility therefore, to be aware of how the system is installed on their individual machine and know which gauge, (horizontal or vertical) to read.

When the level sen sor alarm sounds, au to matic in ter locks make it im pos si ble to drive the SR or raise the plat form. For more com plete in for ma tion see the Level Sen sor sub sec tion of the Safety De vices 2 chapter.

q Engine temperature

engine shuts off. The engine will restart with low pressure but it will only run a few seconds before it automatically shuts off again.

q Platform height vs. drive speed

When the plat form is over 1.7m (5 6") above the ground the drive speed is lim ited to its slow est speed and the en gine revs are also au to mat i cally low ered.

q Dynamic brakes

When you drive an SR down a slope, if the SR be gins to coast (out run the drive mo tors) the hy drau lic sys tem senses the coast ing con di tion. The hy drau lic drive mo tors then be come hy drau lic brakes and the SR is slowed. This ac tion pre vents SRs from speed ing down grades.

q Alternator not charging

Figure 5.1 - Engine Temperature Sensor

There is a tem per a ture sen sor in the en gine. It mea sures the tem per a ture of the an ti freeze-wa ter mix ture as the mix ture leaves the top of the ra di a tor and en ters the top of the en gine. If the tem per a ture reaches 210(F (99(C) an alarm sounds. If the tem per a ture con tin ues to rise, the en gine shuts off when the tem per a ture reaches 230(F (110(C). The en gine will not re start un til the tem per a ture drops below 210(F (99(C).

q Engine oil pressure

Figure 5.3 - Alternator Output Shutdown

When the fan belt breaks, or the al ter na tor out put falls be low a safe level for other rea sons, the en gine au to mat i cally shuts off and an alarm sounds. As long as the SR bat tery is charged you can lower the plat form, in the usual way, from the plat form con trol box or the ground con trol box with out the en gine running.

q Stabilisers

The SR can not be driven un less the sta bi lis ers are com pletely up. If you have just raised the sta bi lis ers but the SR will not drive, dou ble check to be sure all four sta bi lis ers are com pletely up.

Figure 5.2 - Engine Oil Pressure Sensor

There is an oil pressure sensor in the engine. It measures the engine oil pressure at the oil filter. If the pressure falls below a safe operating value the

This chap ter ex plains what each con trol does.

This chap ter does not ex plain how to use the con trols to pro duce use ful work, re fer to the Op er a tion chap ter 8 for that, af ter you have read this chapter.

For op tional-equip ment con trols, see the Op tions chap ter 11 .

See the Emer gency Op er a tion chap ter 9 for the lo ca tion of the emer gency bleed down con trol and for cor rect emer gency bleed down pro ce dures.

The main op er at ing func tions of an SR can be con trolled from the ground con trol box (1) or the plat form con trol box (2).

Ground Control Box

Con trols for op er at ing an SR from the ground are lo cated on the right side of the ma chine on the rear of the hy drau lic com part ment.

NOTE 1 The number of each control corresponds to

Figure 6.3.

NOTE 2 Some switches and indicators are either not

used, or may serve a different purpose depending on the configuration of your machine.

Figure 6.1 - Control Box Locations

Hydraulic Compartment

Figure 6.2 - Battery Switch

1. Battery Switch: This must be ON for the engine to start. When the battery switch is OFF the positive side of the SR battery is disconnected from the electrical system. Lock this switch OFF when the SR is left unattended.

Figure 6.3 - Ground Control Box Controls

1. Emergency Stop: Press the red switch-cover down, at any time, under any conditions, and the entire machine stops - the engine turns off and nothing moves. This switch must be up for anything on the machine to work.

2. Key Switch: This switch works like an automobile ignition switch. Hold the key at the start symbol (extreme clockwise position) until the engine starts then release it to the on position (bar symbol).Turn the key to off (O) if the platform is to stay in one position for a long time. That will turn the engine off and save fuel.

3. Choke Indicator Light: (gasoline engines only): This light will be lit while you choke the engine (see CHOKE below).

3. Glow-Plug Indicator Light: (diesel engines only): This light will be on while the glow plugs are on. Wait, about 30 seconds for the light to go out before you try to start a diesel.

SR3370 & SR2770 – 12696A Rev B page 6 - 1

Page 32

6. Controls

4. Choke: (gasoline engines only): Hold the choke switch up anytime you start a gasoline engine that is at ambient air temperature (a cold engine).

4. Glow Plug: (diesel engines only): This is a momentary contact switch. Press it up then release it just before you start a diesel engine that is at ambient air temperature (a cold engine). This action automatically causes glow plugs to come on for 30 seconds to warm the inside top of each cylinder, thus aiding combustion.

5. Lift Indicator Light: The platform can be raised only when this light is lit. When this light is not lit the platform will not rise because: the platform is not level, or the stabilisers are not properly set.

6. Platform Lift/Lower: Holding this switch up causes the platform to rise. Pushing this switch down causes the platform to lower.

7. Fuel (option): Before starting a dual-fuel engine set the FUEL switch to gasoline (up) or LP gas (down) depending on which you want to use. If you select LP gas, be sure to open the valve on top the LP gas tank.

8. Ground/Platform Selector: Must be down for the ground control box to work. Must be up for the platform control box to work.

NOTE The number of each control corresponds to

Figure 6.4.

Figure 6.4 - Platform Control Box Controls

1. Emergency Stop: Press the red button in at any time, under any conditions, and the entire machine stops - the engine turns off and nothing moves. This switch must be out (on) to start and run the SR from the platform control box, pull the switch and it will pop out (on). Press the switch in (off) if the platform is to stay in one position for a long time. That will turn the engine off and save fuel.

Figure 6.3 Ground Control Box Controls

Platform Control Box

Con trols for op er at ing an SR from the plat form are lo cated on the plat form con trol box.

NOTE The EMERGENCY STOP switch on the ground

control box overrides the one on the platform control box. If the one on the ground control box is off the SR will not start or run, it does not make any difference whether the one on the platform control box is on or off.

2. Start: Turn and hold the switch to the right to start the engine. As soon as the engine starts, release the switch.

3. Choke: (gasoline engines only): Press and hold the switch in anytime you start a gasoline engine that is at ambient air temperature (a cold engine).

3. Glow-Plug: (diesel engines only): This is a momentary contact switch. Press it up then release it just before you start a diesel engine that is at ambient air temperature (a cold engine). This action automatically causes glow plugs to come on for 30 seconds to warm the inside top of each cylinder, thus aiding combustion.

6. Controls

4. Glow-Plug Indicator Light: (diesel engines only): This light will be on while the glow plugs are on. Wait for the light to go out before you try to start a diesel.

5. Safety Control: The SAFETY CONTROL must be squeezed against the JOYSTICK CONTROLLER to activate the joystick controller. If the safety control is not squeezed the joystick controller is inoperative.

6. Joystick Controller: If the LIFT/DRIVE SELECTOR is set to the left (lift function), pulling the joystick controller backward causes the platform to rise, pushing the joystick controller forward causes the platform to lower. If the LIFT/DRIVE SELECTOR is set to the right (drive function), pushing the joystick controller forward causes the SR to move forward, pulling the joystick controller backward causes the SR to move backward. The further you push or pull the controller the faster the motion (except lowering-it occurs at one speed only).

11. Drive Indicator Light: The platform can be driven when this light is lit. When it is not lit the platform will not drive because with the platform raised the base is not level or with the platform raised the axle switches are not set.

12. Stabiliser Manual Switches: Each switch corresponds to one of the stabilisers. Pull a switch backward to lower a stabiliser, push it forward to raise the stabiliser.

13 Auto Level / Stow Switch: Select either auto

level or auto stow, to raise or lower the stabilisers automatically.

14 Horn Switch: Press this switch to operate the

horn.

15. Oil Pressure Warning Light: This indicator light should go off when the engine is started. Stop the engine immediately if this light comes on when the engine is running.

NOTE Squeeze the SAFETY CONTROL anytime you

use the JOYSTICK CONTROLLER.

7. Steering: The rocker switch on top of the JOYSTICK CONTROLLER turns the front wheels left or right depending upon which side of the switch you press.

NOTE The wheels do not return to straight ahead, after

a turn, the way automobile wheels do. You must use the STEERING switch to straighten the wheels after a turn.

8. Lift/Drive Selector: When this switch is set to the left the JOYSTICK CONTROLLER becomes a lift/lower controller to raise or lower the platform. When this switch is set to the right the JOYSTICK CONTROLLER becomes a drive controller to drive the SR forward or backward. The SR will not drive and lift at the same time.

9. Speed: Set the switch to turtle (slow) when you are working in close quarters or if you are new to the machine. Setting the switch to rabbit (fast) doubles the top speed of the SR.

10. Lift Indicator Light: The platform can be raised only when this light is lit. When this light is not lit the platform will not rise because: the platform is not level, or the stabilisers are not properly set.

The ground control box can override the platform control box 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.

The SR is not Electrically insulated.

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

Emergency Stopping

To stop an SR, push ei ther Emer gency Stop switch,

at any time on ei ther the ground con trol box or the

plat form con trol box and the en tire ma chine stops

and noth ing moves.

8. Operation

Fuel type

Af ter you have made the ground con trol / plat form con trol de ci sion you need to know whether the SR has a gas o line or die sel en gine. If it has a gas o line en gine you fur ther need to know whether it is set up to burn LP-only, or dual-fuel (LP or gas o line). If it is set up to burn dual-fuel you have to de cide whether to burn gas o line or LP. The sim plest way to tell what kind of en gine set up you have is to look in the fuel com part ment on the left side of the SR open both fuel compartment doors.

If the only fuel source you see there is a tank labeled GASOLINE FUEL, the SR has a gasoline engine set up to burn gasoline.

If the only fuel source you see is a tank labeled DIESEL FUEL, the SR has a diesel engine.

If the only fuel source you see is one or more LP tanks, the SR has a special gasoline engine set up to burn LP-only.

Figure 8.3

Set the Battery switch • (see Figure 8.3) to on.

If you see a GASOLINE FUEL tank and one or more LP tanks, the SR has a special gasoline engine set up to burn either gasoline or LP.

Once you have de ter mined the type of en gine in stalled and the type of fuel you will burn you should go to the cor re spond ing sub sec tion that ex plains how to start that type en gine. Read the Ta ble Of Con tents at the front of this man ual to see how the dif fer ent sec tions and sub sec tions of this chap ter are arranged.

1. The engine must be running. If not, start it from the platform control box as described above.

8. Operation

Squeeze and hold the Safety Control ƒ against the Joystick Controller • (see Figure

8.19).

Pull the Joystick Controller • backward to raise the platform, or push it forward to lower it. The further you pull the Joystick Controller

• backward, the faster the platform rises. There is only one down speed.

Stabilisers

NOTE: Using the stabilisers.

The platform must be fully lowered to enable the stabilisers to operate.

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

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

Figure 8.19

Set the Lift/Drive Selector • (see Figure

8.19) to lift (left).

NOTE

If the Lift Indicator Light € is not lit, the platform will not go up because: the chassis is not level, the stabilisers are not properly set, or the articulating axles are not set. Correct the problem then continue.

NOTE The platform is about to move. If you have to

make an emergency stop, release the Joystick Controller • and sharply strike the Emergency Stop switch ‚ straight in.

If the platform is up and the ground compresses unevenly under different stabiliser pads the SR 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 SR 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 SR above the ground - use the other three to level the SR as necessary.

The SR will not DRIVE un less all four sta bi lis ers are com pletely raised i.e. If any one of the sta bi lis ers is even slightly low ered the DRIVE func tion is dis abled.

To make a nor mal stop, slowly move the Joy stick Con trol ler • to its cen tered neu tral po si tion then re lease it.

Emergency Operation Procedures

The fol low ing pro ce dures are emer gency pro ce dures only. DO NOT use them for nor mal op er a tion. Their pur pose is to get the plat form and op er a tor safely to the ground when the SR will not start or some other prob lem keeps the plat form from low er ing in the nor mal way, or to move the SR a short dis tance to a safe place when the mo tor will not start.

There are three forms of emer gency op er a tion for the SR.Emer gency stop, emer gency bleed-down, and push ing.

Each is cov ered as a sep a rate sec tion be low.

Emergency Stop

There are two Emer gency Stop switches on an SR.
