The aerial platform is not electrically insulated. Death or serious injury will result from contact with, or inadequate clearance from, an energized conductor.
Do not go closer than the minimum safe approach distance as defined by the Minimum Safe Approach Distance section in Chapter 3 – Safety.
Regard all conductors as energized.
Allow for electrical wire sag and aerial platform sway.
If the platform, booms, or any part of the aerial platform contacts a high-voltage electrical conductor, the entire machine can become electrically charged.
If that happens, remain on the machine and do not contact any other structure or object. This includes the ground, adjacent buildings, poles, and any other objects that are not part of the aerial platform.
Such contact could make your body a conductor to the other object, creating an electrical shock hazard resulting in death or serious injury.
If an aerial platform is in contact with an energized conductor the platform operator must warn ground personnel in the vicinity to stay away. Their bodies can conduct electricity creating an electrical shock hazard resulting in death or serious injury.
Do not approach or leave the aerial platform until the electricity has been turned off.
Do not attempt to operate the lower controls when the platform, booms, or any part of the aerial platform is in contact with a high-voltage electrical conductor or if there is an immediate danger of such contact.
Personnel on or near an aerial platform must be continuously aware of electrical hazards, recognizing that death or serious injury can result from contact with an energized conductor.

Prestart Inspection
Perform a prestart inspection before each shift as described in Chapter 7. Do not use the aerial platform on the job unless you are trained and authorized to do so.
booms, or platform. Allow sufficient room and time to stop movement to avoid contact with structures or other hazards.
Always look in the direction of movement.
Work Place Inspection and Practices
Do not use the aerial platform as a ground connection when welding.
The welding ground clamp must be attached to the same structure that is being welded.
Electrical current flow can be very intense, causing serious internal damage to some components.
Inspect the area before and during aerial platform use. The following are some potential hazards that may be in the work place.
•Debris
•Slopes
•Drop-offs or holes
•Bumps and floor obstructions
•Overhead obstructions
•Unauthorized persons
•High voltage conductors
•Wind and weather conditions
•Inadequate surface and support to withstand load forces applied by the aerial platform in all operating configurations
Before using the aerial platform in any hazardous
(classified) location, make certain it is approved and of the type required by ANSI/NFPA 505 for use in that particular location.
Drive with care and at speeds compatible with the work place conditions.
Use caution when driving over rough ground, on slopes and when turning.
Do not engage in any form of horseplay or permit riders any place other than in the platform.
Secure all accessories, containers, tools, and other materials in the platform to prevent them from accidentally falling or being kicked off the platform. Remove all objects that do not belong in or on the aerial platform.
Never steady the platform by positioning it against another platform.
Warning
The potential for an accident increases when operating an aerial platform that is damaged or malfunctioning. Death or serious injury could result from such accidents. Do not operate the aerial platform if it is damaged or malfunctioning.
Do not operate the aerial platform if it is damaged or not functioning properly. Qualified maintenance personnel must correct the problem before putting the aerial platform back into service.
Know and understand the job site traffic-flow patterns and obey the flagmen, road signs and signals.
While operating the aerial platform, a good safety practice is to have qualified personnel in the immediate work area 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
Danger
Pinchpointsmayexistbetweenmovingcomponents. Death or serious injury will result from becoming trapped between components, buildings, structures, orotherobstacles.Makesurethereissufficientclearance around the machine before moving the chassis,
Operation
Use three points of support when entering or exiting the platform. For example, use two hands and one foot when climbing into the platform.
Never cover the platform floor grating or otherwise obstruct your view below. Make sure the area below the platform is free of personnel before lowering.
Keep both feet positioned firmly on the platform floor.
Operate the controls slowly and deliberately to avoid jerky and erratic operation.
Always stop the controls in neutral before going in the opposite direction.

Chapter 3 – Safety
Tip-Over and Falling Hazards
Operate the aerial platform only on a firm, flat, level surface capable of withstanding all load forces imposed by the aerial platform in all operating conditions. Refer to theGeneralSpecificationschartforthemaximumwheel load and ground pressure. Raise the booms only when the aerial platform is on level ground.
Danger
The aerial platform can tip over if it becomes unstable. Death or serious injury will result from a tip-over accident. Do not drive or position the aerial platform for elevated use near any drop-off, hole, slope, soft or uneven ground, or other tip-over hazard.
All platform occupants must wear a fall restraint device connected to a lanyard anchor point.
It is best not to transfer from the platform to another structure or from the structure to the platform, unless that is the safest way to do the job. Judge each situation separately taking the work environment into account. If it is necessary to transfer from the platform to another structure the following guidelines apply:
1.Where possible, place the platform over a roof or walking structure to do the transfer.
2.Transfer your anchorage from one structure to the other before stepping across.
3.Remember that you might be transferring to a structure where personal fall arrest is required.
4.Use the platform entrance, do not climb over or through the guardrails.
Do not operate the aerial platform in windy or gusty conditions. Do not add anything to the aerial platform that will increase the wind loading such as billboards, banners, flags, etc.
Never operate the aerial platform without all parts of the guardrail system in place and the gate closed. Make sure that all protective guards, cowlings and doors are securely fastened.
Do not exceed the platform capacity as indicated on the platform rating placard on the platform. Do not carry loads that extend beyond the platform guardrails without prior written consent from Snorkel.
Do not operate the aerial platform from trucks, trailers, railway cars, floating vessels, scaffolds or similar equipment unless the application is approved in writing by Snorkel.
Do not use the aerial platform as a crane, hoist, jack or for any purpose other than to position personnel, tools and materials.
Do not climb on the guardrails or use ladders, planks or other devices to extend or increase the work position from the platform.
Take care to prevent rope, electrical cords, and hoses, etc., from becoming caught in or on the aerial platform.
If the platform or booms becomes caught on an adjacent structure or other obstacle and is prevented from normal motion, reverse the control to free the platform.
If control reversal does not free the platform, evacuate the platform before attempting to free it.
Electrical System
Charge the batteries in a well-ventilated area free of flame, sparks or other hazards that might cause fire or explosion.
Do not operate any of the aerial platform functions while the battery charger is plugged in.
Warning
Batteries give off hydrogen and oxygen that can combine explosively. Death or serious injury could result from a chemical explosion. Do not smoke or permit open flames or sparks when checking the 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 the batteries.
Batteries contain sulfuric acid that can damage your eyes or skin on contact.
Wear a face shield, rubber gloves, and protective clothing when working around 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.
Hydraulic System
Thehydraulicsystemcontainshoseswithhydraulicfluid under pressure.
Danger
Hydraulic fluid escaping under pressure can have enough force to inject fluid into the flesh. Serious infection or reaction will result if medical treatment is not given immediately. In case of injury by escaping hydraulic fluid, seek medical attention at once.
TB66J – 0083740 |

Chapter 3 – Safety
Do not place your hand or any part of your body in front of escaping hydraulic fluid. Use a piece of cardboard or wood to search for hydraulic leaks.
Engine and Fuel Handling Precautions
Refer to the engine manufacturer’s Operator’s Manual for complete information on safe engine operation, maintenance and specifications.
Danger
Engine exhaust contains carbon monoxide, a poisonous gas that is invisible and odorless. Breathing engine exhaust fumes will cause death or serious illness. Do not run the engine in an enclosed area or indoors without adequate ventilation.
Operate dual fuel machines on LPG fuel when indoors to reduce exhaust fumes and carbon monoxide.
Be careful not to run the diesel fuel tank empty. Bleed the fuel system if air enters the lines between the tank and the injection pump.
Allow the engine to return to idle before shutting the engine off.
Do not smoke or permit open flames while fueling or near fueling operations.
Never remove the fuel cap or fill the fuel tank while the engine is running or hot. Never allow fuel to spill on hot machine components.
Maintain control of the fuel filler nozzle when filling the tank. Spilled fuel is a potential fire hazard.
Do not overfill the fuel tank. Allow room for expansion.
Clean up spilled fuel immediately.
Tighten the fuel tank cap securely. If the fuel cap is lost, replace it with an approved cap from Snorkel. Use of a non-approved cap without proper venting may result in pressurization of the tank.
Never use fuel for cleaning purposes.
For diesel engines, use the correct fuel grade for the operating season.
Caution
Engine coolant escaping under pressure may cause serious burns. Shut the engine off and let it cool before removing the radiator cap.
Let the engine and radiator cool before adding coolant.
Placards and Decals
The aerial platform is equipped with placards and decals that provide instruction for operation and accident prevention. Do not operate the aerial platform if any placards or decals are missing or not legible.

Figure 4.7 – Lower Control Panel
High Engine Temperature Alarm
If the coolant in a Cummins or GM engine exceeds the engine operating temperature an alarm will sound and the engine will shut off.
If the oil in a Deutz engine exceeds 230°F (110°C) an alarm will sound and the engine will shut off. Any time there is no alternator current being produced, an alarm will sound and the engine will shut off. This prevents high engine temperature if the fan belt breaks.
Do not restart the engine until the condition that caused the overheating has been corrected.
Low Oil Pressure Alarm
The low oil pressure alarm sounds when the engine oil pressure is near the lower limit for safe engine operation. If the alarm sounds, lower the platform to the ground and then turn the engine off.
If the engine oil pressure falls below a safe operating value the engine will shut off.
The engine can be restarted with low oil pressure, but it will only run for a few seconds before it shuts off again.
Do not restart the engine until the condition that caused the low oil pressure has been corrected.

Fuel Gauge
Figure 5.4 – Fuel Tank
Read the fuel gauge at the line in the clear plastic window.
The gauge indicates the fuel tank level in fractions of a full tank.
Note
Do not run a diesel fuel tank empty. Air in the fuel line makes the engine hard to start.
LPG tanks have a fuel gauge that has two scales. One scale measures the fuel level when the tank is mounted vertical and the other is used when the tank is mounted horizontal (refer to Figure 5.5).
Horizontal Scale
Figure 5.5 – LPG Tank
The LPG tank is mounted horizontally behind the rear cowling door on the right side of the machine.
Read the horizontal scale to determine the fuel level.
Engine Oil
The engine oil level is measured with a dipstick. The dipstick is the only way to accurately determine the engine oil level. The engine oil level should always be between the add and full marks on the dipstick.
Hydraulic Fluid Filter Gauge
Thefluidfiltergauge(refertoFigure5.6)islocatedonthe return line filter on the top of the reservoir.The reservoir is behind the door on the left side of the turntable.
During high pump flow situations, the gauge indicates the condition of the filter.
When the needle on the gauge is in the red zone, its time to change the filter.
Filter Gauge
Figure 5.6 – Hydraulic Fluid Filter Gauge
Fluid Level and Temperature Gauge
A sight gauge on the right side of the hydraulic reservoir displays the level and temperature of the hydraulic fluid (refer to Figure 5.7).The reservoir is behind the door on the left side of the machine.
Onlyreadthefluidlevelwhentheaerialplatformisinthe stowed position, booms completely down and retracted. Otherwise, the cylinders act as large reservoirs for hydraulic fluid making the level appear too low.
The fluid should be between the minimum and maximum lines.
If the temperature rises above 200°F (93°C) stop machine operation and let the fluid cool before resuming operation.
