Electrical Hazard Warning

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.

Any SR2770 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 SR a recommended safety practice is to have trained and qualified personnel in the immediate work area of the SR2770 to:

●

Help in case of an emer gency.

●

Op er ate emer gency con trols as re quired.

●

Watch for loss of con trol by plat form op er a tor.

●

Warn the op er a tor of any ob struc tions or haz ards that may not be ob vi ous to them.

●

Watch for soft ter rain, slop ing sur faces, drop-offs, etc., where sta bil ity could be jeop ar dized.

●

Watch for by stand ers and never al low any one to be un der, or to reach through the booms while op er at ing the ae rial 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.

Do not en gage in any form of “horse play” or “stunt driv ing” while op er at ing the SR2770.

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.

DANGER

■

Tipover and Falling Hazards

Operate the SR only on a firm, flat, level surface capable of withstanding all load forces imposed by the SR2770 in all operating conditions.

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

■

General Safety Precautions

Do not mod ify the 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 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 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 SR near a flame or spark. Hy drau lic oil and gas o line are flam ma ble and can ex plode.

NOTE:

This machine is equipped with an internal combustion engine (in it's standard configuration) and should not be used on or near any unimproved forest-covered, brush-covered or grass covered land unless the engine's exhaust system is equipped with a spark arrester meeting applicable laws.

Safety Decals and Placards

There are sev eral safety de cals and plac ards on the SR2770. Their lo ca tions and de scrip tions are shown in this sec tion. Take time to study them.

Be sure that all the safety decals and placards on the SR2770 are legible. Clean or replace them if you cannot read the words or see the pictures. Clean with soap & water and a soft cloth. Do not use solvents.

ENSURE you use an approved fuel container with appropriate fuel filler nozzle

Do not fill the fuel tank to ca pac ity. Al low room for ex pan sion.

If gasoline is spilled, clean up spilled fuel immediately, push/tow the SR away from the area of the spill and avoid creating any source of ignition until the spilled fuel has evaporated.

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.

The wa ter gauge is lo cated on the ground con trol box. It shows the tem per a ture of the wa ter-antifreeze mix ture in the en gine block. The typ i cal op er at ing-temperature range for Kubota en gines is 180°F to 205°F (82°C to 96°C), both die sel and gas o line. (See the “Au to matic Shut-Offs & Cir cuit Breakers ” chap ter 5 for more in for ma tion.)

■

Amps

●

The oil dipstick is the only way to accurately gauge if the engine oil level is correct.

●

Engine oil level should always be between the lines on the dipstick - never above the top line or below the bottom line.

Gas o line Die sel

Figure 4.3 - Oil Dipstick Levels for Gasoline

and Diesel Engines

Figure 4.2 - Ammeter Gauge

The AMPS gauge shows the electric current from the alternator to the battery. When the engine is running, the needle in the AMPS gauge should not be to the left of “0.” Under normal operating conditions, after the engine has been running for a few minutes, the AMPS gauge should read “0.”

■

Engine Oil

Engine oil level is measured with a dipstick. Oil capacities given in the “Specifications” chapter 3 are approximate. True values will vary from machine to machine due to slight variations or modifications during production.

■

Hydraulic Oil Level

Figure 4.4 - Hydraulic Oil Level

The hydraulic-oil level gauge is on the side of the hydraulic oil tank. It shows the actual level of oil inside the tank. Read it only when the platform is completely down. Otherwise, the lift cylinders become large reservoirs for hydraulic oil and the oil level in the tank will be low. The oil level should be within ( 0.25 inches, 6.4 mm) of the line.

Automatic Shut-offs

❑ Level sensor

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 ” chap ter.2

❑ Engine temperature

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

❑ 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.

❑ 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 SR’s from speed ing down grades.

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-water 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 be low 210(F (99(C).

❑ Alternator not charging

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 run ning.

❑ 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.

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

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.

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.

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

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.

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

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.

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

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).

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

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

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.

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.

Joystick Controller If the LIFT/DRIVE SELECTOR is set to the left (lift function), pushing the joystick controller forward causes the platform to rise, pulling the joystick controller backward 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).

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.

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.

Stabilisers Each switch corresponds to one of the stabilisers. Pull a switch backward to lower an stabiliser, push it forward to raise the stabiliser (see Figure 6.4).

❑ Self Levelling Stabilisers (optional)

Note:

Refer to Figure 6.5 below for Automatic Stabiliser Switch operation. All other switch/indicator functions remain the same for the Platform Control Box.

13 For units fitted with self levelling stabilisers

the following applies: To raise or lower the stabilisers ‘automatically’ switch 13 is used.

NOTE

Squeeze the SAFETY CONTROL anytime you use the JOYSTICK CONTROLLER.

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.

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.

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.

Press switch 13 momentarily (3 - 4 seconds) to lower the stabilisers. The stabilisers will lower and level the platform automatically.

Switch 13 can also be used to raise the stabilisers to the stowed position. To do so press (momentarily) in the raise direction and all the stabilisers will raise automatically.

14 To operate the stabilisers individually switch

14 must be held “ON” (down) while each individual switch 12 is used.

Operating Procedures

This chap ter ex plains how to start and run an SR that has ei ther a gas o line or die sel en gine. Starting a gas o line en gine that is set up to burn LP-only or dual-fuel is also dis cussed in this chap ter. Read and un der stand all the pre vi ous chap ters be fore you be gin to op er ate an SR

■

Control Stations

An SR can be started and op er ated from the ground con trol box or from the plat form con trol box.

NOTE

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 either Emergency Stop switch, at any time on either the ground control box or the platform control box and the entire machine stops and nothing moves.

Figure 8.1 - Emergency Stop Switch at

Ground Control Box

Ground con trol box Emer gency Stop switch lo ca tion.

DO NOT attempt to operate the SR ground controls if the platform, scissor assembly or any other conducting part of an SR is in contact with energized electrical wires or if there is an immediate danger of such contact.

NOTE

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

Operation Considerations

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

Be gin at the sec tion en ti tled “Op er ating From The Ground con trol Box” if you in tend to start and run the SR from the ground con trol box.

SR2770 – 11669A page 8 - 1

Page 45

8. Operation

Be gin at the sec tion en ti tled “Op er ating From The Plat form Con trol Box” if you in tend to start and run the SR from the plat form.

❑ 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 com part ment 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.

Figure 8.3

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

●

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.

●

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 ar ranged.

Stabilisers

NOTE:

Using the stabilisers.

The plat form must be fully low ered to en able the sta bi lis ers to op er ate.

Once the plat form is raised the sta bi lis ers can not be set or ad justed.

Be fore op er at ing the sta bi lis ers check to see that the ground con di tions un der the four sta bi liser pads (see Fig ure 8.22) is firm, sta ble and un ob structed.

■

Setting the stabilisers

Figure 8.22

1. The engine must be running and the SR set

for platform control box  operation (see Figure 8.22).

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.

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.

When us ing the sta bi lis ers al ways check that all four are firmly on the ground be fore rais ing the plat form.

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.

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.

Transporting

❑ Trailering

SR’s weigh up to 2800kg (6272lbs) depending on the model. Loading ramps must be able to support that weight. Transport trailers must be able to safely transport that weight.

SR brake and drive systems are not designed for grades over 35%. Drive slowly and carefully on all slopes and loading ramps.

To safely drive an SR onto a trans port trailer:

1. Visually inspect the alignment of the loading ramp and the truck or trailer. They should both be on the same straight line.

2. Set the SR ground control box for platform operation.

5. Visually check (from the platform) to be sure the SR is aligned with the ramp and the ramp is still aligned with the truck or trailer. All should be in a straight line.

Death or serious injury can result from losing control of an SR during loading or unloading. Always drive up or down a grade with the Speed switch set to turtle (slow).

Troubleshooting

All of the ac tions de scribed in this chap ter may be per formed by an SR op er a tor, a trained and qual i fied ser vice tech ni cian is not re quired.

The first col umn, of the fol low ing chart, lists some com mon prob lems en coun tered by SR op er a tors.

The sec ond col umn lists some of the causes for each prob lem. The third col umn lists rem e dies.

❑ Operator Troubleshooting Chart

Problem Cause Remedy

Engine will not start. Battery switch set to off. Turn battery switch to on.

Any problem that cannot be fixed by actions listed below should be referred to a trained and qualified SR service technician.

Emergency Stop switch(es) not on.

Key switch set to off. Set the Key switch to on (the bar symbol).

Ground/Platform Selector switch set to wrong location.

Circuit Breaker tripped. Push the circuit breaker in.

Fuel switch not set correctly.

Out of fuel.

Set the ground control Emergency Stop switch to on (up). Also, if you are trying to start at the platform control box you should pull the Emergency Stop switch, at the platform control box, until it pops out (on).

If you are trying to start from the ground control box, set the Ground/Platform selector to ground (down). If you are trying to start from the platform, set the selector to platform (up).

If you are trying to start a dual-fuel engine be sure the fuel switch is set to the correct fuel.

DANGER: Keep flames and lit tobacco away from open fuel tanks.

Remove the cap from the gasoline or diesel tank to see if there is fuel.

Check the gauge(s) on top of the LP tank(s). If you are using LP gas, be sure the valve on top of the tank is open.

Clogged air filter. Visually check the air filter gauge.

Engine oil too thick for ambient temperature.

Stabilisers inoperative Platform not completely

down.

All systems sluggish. Hydraulic oil is too thick. Check for correct grade of Hydraulic Oil.

SR will not drive forward or reverse.

SR2770 – 11669A page 13 - 1

Free-wheeling valve is open.

Check engine oil chart in “Specifications” chapter 3 for correct oil weight.

Completely lower the platform.

Allow time for machine to warm up.

Close the free-wheeling valve.

Page 71

13. Operator's Troubleshooting

Problem Cause Remedy

Platform will not go up or down.

Engine is not running. Start the engine from the control station

where you will operate the SR.

Switches set wrong (Lift Indicator light is lit).

SR is not level. (Lift Indicator light is not lit and the Level Sensor Alarm is sounding).

The Stabilisers (if present) are not properly set. (Lift Indicator light is not lit).

For ground control operation:

Ground/Platform Selector = Ground Machine/Generator = Machine (if equipped with AC generator)

For platform control box operation:

Ground/Platform Selector = Platform Machine/Generator = Machine (if equipped with AC generator) Lift/Drive Selector = Lift

Squeeze and hold the Safety Control then push Joystick Controller forward to go up or pull it backward to go down.

If the SR has stabilisers use them to level the SR. Otherwise, use adequate shoring to level the SR then chock the wheels to prevent the SR from being driven once the platform is raised.

If you are using the stabilisers, one or more of them is not down quite far enough. Lower each stabiliser a few inches more to be sure each is firmly in contact with the ground.

Platform will not drive forward or reverse when raised.

Unit not level. Articulating axle operated.

If you are not using the stabilisers, one or more of them is not fully up. Raise each stabiliser completely up.

Situation normal, lower platform to drive.
