Effective July 1995 Electrical Hazard ■ Electrical Hazard Warning DANGER THE MHP AERIAL WORK PLATFORM IS NOT ELECTRICALLY INSULATED. If the platform, booms, or any other conductive part of a MHP contacts a high-voltage electrical conductor, the result can be SERIOUS INJURY or DEATH for persons on or near the machine. 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 allow for sag and sway in the wires and the work platform. If a MHP comes in contact with a live electrical conductor, the entire machine can be charged. If that happens, you should remain on the machine and not contact any other structure or object within reach. That includes the ground, adjacent buildings, poles, and any object not a part of the MHP. Such contact could make your body a conductor to the other object creating an electrical shock hazard resulting in SERIOUS INJURY or DEATH. DO NOT attempt to enter or leave the MHP until you are sure the electricity has been turned off. If a MHP is in contact with a live conductor, the platform operator MUST warn others on the ground in the vicinity of the MHP to STAY AWAY from the machine, since their bodies can also form a path for electricity to ground thus creating an electrical shock hazard with possible ELECTROCUTION and DEATH. DO NOT attempt to operate the MHP ground controls when the platform, booms, or any other conducting part of a MHP is in contact with electrical wires or if there is an immediate danger of such contact. Regard all conductors as energized. Personnel working on or near a MHP must be continuously aware of electrical hazards, recognizing that SERIOUS INJURY or DEATH can result if contact with an electrical wire does occur.

Safety ■ Safe Operation Knowledge of the information in this manual, and proper training, provide a basis for safely operating the MHP15/44. Know the location of all the controls and how they operate to act quickly and responsibly in an emergency. Safety devices reduce the likelihood of an accident. Never disable, modify, or ignore any safety device. Safety alerts in this manual indicate situations where accidents may occur. If any malfunction, hazard or potentially unsafe condition relating to capacity, intended use, or safe operation is suspected, stop the operation of the MHP and seek assistance. The operator bears ultimate responsibility for following all manufacturers instructions and warnings, regulations and safety rules of their employer and/or any country or regional law. DANGER The MHP is not electrically insulated. Death or serious injury can result from contact with, or inadequate clearance from, an energised conductor. Do not go closer than the minimum safe approach distance as defined by ANSI. ANSI publications define minimum distances that must be observed when working near bus bars and energised power lines.

Remove all loose objects stored in or on the machine, particularly in the platform. Remove all objects which do not belong in or on the machine. Do not operate an MHP15/44 that is damaged or not functioning properly. Do not use the MHP until the machine has been repaired by a qualified maintenance person. Do not operate a MHP15/44 that does not have all its decals and placards attached and legible. Watch for bystanders and never allow anyone to be under, or to reach through, the machine and its equipment while operating. Use the recommended transport device when loading the machine. ■ Operation If you encounter any suspected malfunction of the aerial platform, or any hazard or potentially unsafe condition relating to capacity, intended use, or safe operation, cease operation immediately and seek assistance from management. Use three points of support when getting on or off the platform (two hands and one foot or a similar set of points). Keep the platform clean. Maintain a firm footing 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. Do not dismount while the platform is in motion or jump off the machine. 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. Secure all accessories, containers, tools, and other materials in the platform to prevent them from accidentally falling or being kicked off the platform. page 1 - 2 MHP15/44 – 12459A 1. Safety ■ 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. DANGER 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 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 purpose other than to position personnel, their tools, and materials. Do not operate the MHP15/44 in winds, or wind gusts, of 28 mph, 45kph 12.5 m/s) or more and do not add anything to the MHP15/44 that will increase the wind loading (banners, flags, etc.). ■ General Safety Precautions Do not operate the MHP15/44 from a position on trucks, trailers, railway cars, floating vessels, scaffolds, or similar equipment unless the application is approved in writing by Snorkel. Do not modify the MHP15/44 in any way. 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 override any of the safety features of the MHP15/44. Under normal working conditions it is best not to transfer from the platform to another structure or vice versa, unless that is the safest way to do the job. Each situation must be judged separately taking the work environment into account. The following 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 platform occupants MUST wear and use fall restraint. Attach fall restraints to the platform lanyard anchor points. 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 exceed the unrestricted platform capacity as indicated on the capacity placard at the entrance to the platform. Do not carry loads from any point outside of the platform. Make sure that all protective guards, cowlings, and doors are in place and secure. Be sure the guardrail system, including the gate, is in place and secure. MHP15/44 – 12459A When parts or components are replaced, they shall be identical or equivalent to original Snorkel parts or components. ■ Hydraulic System Precautions The hydraulic system contains hoses with hydraulic fluid under pressure. DANGER 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. Do not attempt repairs to hydraulic systems unless you are trained. Refer to experienced repair personnel for help. ■ Fire Prevention Never operate your MHP near a flame or spark. Hydraulic oil and gasoline are flammable and can explode. 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. If a spark arrester is used, it should be page 1 - 3 1. Safety maintained in effective working order by the operator. ■ Engine and Fuel Handling Precautions DANGER 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 refuel your MHP outdoors in a clear area void of gas fumes or spilled gas. Never remove the fuel cap or refuel a gasoline engine while the engine is running or hot. ALWAYS allow the engine to cool before refueling. Never allow fuel to spill on hot machine components. DANGER DO NOT smoke or permit open flames while fueling or near fueling operations. Maintain control of the fuel filler nozzle when filling the tank. CAUTION ENSURE you use an approved fuel container with appropriate fuel filler nozzle (see picture below) area of the spill and avoid creating any source of ignition until the spilled fuel has evaporated. 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. ■ Batteries Charge batteries in a well ventilated area free of flame, sparks, or other hazards that might cause fire or explosion. WARNING 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. 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. ■ Safety Decals and Placards There are several safety decals and placards on the MHP15/44. Their locations and descriptions are shown in this section. Take time to study them. CAUTION Be sure that all the safety decals and placards on the MHP15/44 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. Correct Method to Fill MHP15/44 Fuel Tank Do not fill the fuel tank to capacity. Allow room for expansion. If gasoline is spilled, clean up spilled fuel immediately, push/tow the MHP away from the page 1 - 4 You MUST replace a decal or placard if it is damaged, missing, or cannot be read. If it is on a part that is replaced, make sure a new decal or placard is installed on the replaced part. See your Snorkel dealer for new decals and placards. MHP15/44 – 12459A 1.

Safety Devices ■ Safety Device Information ❑ At platform control box For emergency operation controls and procedures, see the “Emergency Operation” chapter 9, in this manual. The devices listed in this chapter are safety devices. They are on the MHP15/44 to increase safety in the work place for both the operator and other people near the MHP15/44. WARNING DO NOT by pass, disable, modify, or ignore any of these devices. Check them carefully at the start of each work shift to see that they are in working order (see “Daily Inspection and Maintenance” chapter 7). If any is found to be defective, remove the MHP15/44 from service immediately until a qualified service technician can make repairs. ■ Emergency Stop Switches ❑ At ground control box Figure 2.2 - Emergency Stop Switch at Platform Control Box Press the large red EMERGENCY STOP switch in, at any time, under any conditions and the entire machine stops, and nothing moves. This emergency stop switch must be out (on) to control the MHP15/44 from the platform (pull the switch and it will pop out). NOTE: The ground control box is designed to override the platform control box. If the platform control box EMERGENCY STOP switch is in (off) the ground control box can still be used to start and operate the MHP15/44. ■ Other Safety Devices ❑ Lanyard anchor points Figure 2.1 - Emergency Stop Switch at Ground Control Box Press the red EMERGENCY STOP switch cover down, at any time, under any conditions and the entire machine stops, and nothing moves. This emergency stop switch cover must be up and the switch turned on for anything on the MHP15/44 to work. MHP15/44 – 12459A Figure 2.3 - Lanyard Anchor Points All personnel on the platform should attach their fall restraint lanyards to one of the lanyard anchor points. page 2 - 1 2. Safety Devices ❑ Gravity gate ❑ Foot switch Figure 2.6 - Foot Switch Figure 2.4 - Gravity Gate The gravity gate is the place in the platform guardrail system where you should enter and leave the platform. Raise the gate and step under it onto the platform. Once you have entered the platform and attached your fall restraint lanyard to an anchor point, check to see that the gravity gate has fallen back into place. The foot switch prevents the platform from moving if something accidentally pushes one of the platform-moving controls on the platform control box. Stepping on the foot switch is an action that must be performed, at the same time as another action, to make the platform move. ❑ Bubble level ❑ Guardrails Figure 2.7 - Bubble Level A bubble level is located on the trailer side rail, beside the outrigger controls. Watch the bubble level while you set the outriggers. Lower the outriggers, one at a time, just enough to center the bubble in the circle on top of the guage. When the bubble is centered the platform is level and can be safely raised. Figure 2.5 - Guardrails The guardrails help protect you from falling off the platform. Be sure the guardrails are properly installed and that the gravity gate or swinging gate is in place. page 2 - 2 MHP15/44 – 12459A 2. Safety Devices ❑ RCD/ELCB AC outlet RCD Power Outlet At Platform Power Input Connector Figure 2.8 - RCD/ELCB AC Outlet The RCD (Residual Current Device) is located at the base and will protect against short circuits to earth. When there is a short circuit the RCD will shut down the 230v AC power to the platform outlet. To reset the outlet disconnect the power tool lead from the platform box and reset the RCD at the base. If the problem persists call a trained service technician. ❑ Flashing light Figure 2.9 - Flashing Light The flashing light alerts people that the MHP15/44 is moving. The light flashes at about one flash per second any time the MASTER KEY switch is on. There is no ON/OFF switch for the flashing light, it cannot be turned off while the MHP15/44 is running.

Operation ■ Operating Procedures This chapter explains how to properly start and operate an MHP15/44. Read and understand all the previous chapters in this manual before you begin to operate an MHP15/44. CAUTION If you use the MHP15/44 for painting be sure the optional sandblast protection kit is installed to protect the hydraulic cylinder rods from paint. Do not leave the MHP15/44 engine running if you are sandblasting. Sand drawn into the air intake can erode engine parts. ■ Control Stations An MHP15/44 can be operated from the ground control box or from the platform control box. There are basically two differences between ground control and platform control operations, both are safety related: 1. 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. 2. The outriggers can only be selected from the ground control box and only when the booms are in the stowed position. Figure 8.1 - Ground Control Box Emergency Stop Switch Location. ■ Emergency Stopping Upper Control Box To stop an MHP15/44 from the upper control box push the Emergency Stop switch in (see Figure 8.2). DANGER The MHP15/44 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. DO NOT attempt to operate the MHP15/44 ground controls if the platform, booms, or any other conducting part of an MHP15/44 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. ■ Emergency Stopping Lower Control Box Figure 8.2 - Platform Control Box Emergency Stop Switch Location. NOTE For a complete discussion of the Emergency Stop switches, see “Controls” chapter 6, in this manual. To stop an MHP15/44, from the lower control box press the Emergency Stop switch cover down (see Figure 8.1). MHP15/44 – 12459A page 8 - 1 8. Operation ■ Operation Considerations To use this chapter, first decide whether you will be starting and operating the MHP15/44 from the ground control box or the platform control box. Begin at the section entitled "Starting From Ground Control Box", if you intend to start and run the MHP15/44 from the ground station. Begin at the section entitled "Starting From Platform Control Box", if you intend to start and run the MHP15/44 from the platform. ■ Starting From Ground Control Box Before you begin to operate the MHP15/44 from the ground control box, a qualified operator must perform the "Daily Inspection and Maintenance" as described in chapter 7, of this manual. To start the engine from the ground control box do the following: 1. Set the Emergency Stop switch to ON (see Figure 8.3). 5. Turn the key to Start and hold it there until the engine starts or for a maximum time of 6 seconds. When the engine starts release the key and the choke switch , if you used it (see Figure 8.3). CAUTION If the engine does not start in 6 seconds turn the key off and release the choke. Wait 60 seconds before trying to restart the engine again. Continual cranking of the starter motor will only result in its damage. The engine should now be running, and the MHP15/44 is ready to begin work. ■ Stabilizer Operation Ensure the boom/stabilizer switch (item on the ground control box) (see Figure 8.3) is set to stabilizer. Activate the stabilizers with the valve levers ensuring that the front stabilizers are lowered first to prevent damage to the jockey wheel. Activate the rear stabilizers and level the machine using the level bubble adjacent to the control levers. WARNING When levelling the machine in either the manual or automatic mode care is required to ensure that all of the foot plates are firmly on the ground, the machine is level and the lift enable light is ON before entering the platform. ■ Self Levelling Stabilizers (Option) Figure 8.3 - Ground Control Box Starting 2. Set the Platform/Ground Selector switch to GROUND (see Figure 8.3). 3. Insert the key (see Figure 8.3) into the Master Key Switch and turn the key on. 4. If the engine is at ambient temperature (cold), hold the Choke / Cold Start Switch (see Figure 8.3) up throughout the next step. page 8 - 2 Figure 8.4 - Auto Level Controls For units fitted with self levelling stabilizers the following applies. 1. Set switch to automatic mode (see Figure 8.4) MHP15/44 – 12459A 8. Operation 2. Press switch and hold to lower the stabilizers (see Figure 8.4). The stabilizers will lower and the machine will “level” automatically. NOTE: Switch is also used to raise the stabilizers to the stowed position. To do so press switch in the raise direction and all the stabilizers will raise automatically. NOTE: Although this option is designed to automatically set the stabilizers it is also possible to set the stabilizers independently using the “manual mode”. ❑ Setting the stabilizers manually 1. Set switch to manual mode (see Figure 8.4). 2. Operate each switch (see Figure 8.4) to raise or lower each stabilizer one at a time. Use the level bubble (see Figure 2.7 in Safety Devices Chapter) to check the machine is level. Figure 8.5 2. Set the Platform/Ground Selector (see Figure 8.5) at the ground control box to PLATFORM. WARNING When levelling the machine in either the manual or automatic mode care is required to ensure that all of the foot plates are firmly on the ground, the machine is level and the lift enable light is ON before entering the platform. ■ Starting From Platform Control Box Before you begin to operate the MHP15/44 from the platform control box, a qualified operator must perform the "Daily Inspection and Maintenance" as described in chapter 7, of this manual. To start the engine from the platform control box you must first set some switches on the ground control box, including setting the outriggers and leveling the machine. (See page 8-2 for information on setting the stabilizers) 1. Insert the key into the Master Key Switch at the ground control box and turn the key on (see Figure 8.5). MHP15/44 – 12459A Figure 8.6 3.
