Working with the MEWP

 Safety regulations for truck operation

Travel routes and work areas
Only use lanes and routes specifically designated for truck traffic. Unauthorized third parties must stay away from work areas. Loads must only be stored in places specially designated for this purpose. The MEWP must be operated only in work areas with sufficient lighting, in order to avoid danger to personnel and materials. Additional optional equipment is necessary if the MEWP is operated in areas with insufficient lighting. Operation is permitted only in enclosed areas.

• Do not exceed the permissible surface and point loading on the travel lanes. At blind spots get a second person to assist. Driver must ensure that the loading dock cannot be removed or come loose in loading/unloading.

Conduct while travelling
The operator must adapt the travel speed to local conditions. The operator must drive slowly when passing through bends or narrow passageways, swing doors and blind spots. The operator must always keep a safe braking distance from any vehicle in front, and must be in control of the working platform at all times. Abrupt stopping (except in emergencies), rapid U turns and overtaking at dangerous or blind spots are not permitted. It is forbidden to lean out or reach out while travelling out of the working and operating area.

Tilt sensors
Tilt sensors are active over a platform height of 500mm, which prevents the MEWP from tipping over when travelling on inclined surfaces. At inclination angles over 1.5°, travel and lifting are shut off. The operator platform must then be lowered. The MEWP can then be shunted out of the hazard area.

Travel visibility
The operator must look in the travel direction and always have a clear view of the route ahead. If carrying loads that affect visibility, the MEWP must travel against the load direction. If this is not possible, a second person must walk alongside the MEWP to observe the travel path while maintaining contact with the operator. Travel only at slow speed and with particular caution. Stop the MEWP immediately if contact with a second person is lost.

Traveling on slopes and inclines
Do not travel on slopes and inclines up to 8%. The slopes or inclines must be clean and non-slip. The truck must always be driven with the load facing uphill. It is forbidden to turn, drive at an oblique angle, or park the MEWP on inclines or slopes. When traveling on inclines, the driver must only drive the truck at slow speed and be ready to brake at any moment.

Entering the lifts
Access to this MEWP is only permitted if the lifts have sufficient capacity, are suitable for driving on and authorized. When entering lifts, the MEWP must have the load in front and must take up a position which does not allow it to come into contact with the walls of the lifts.

Type of loads to be carried
Loads must always be positioned safely and carefully. Use suitable precautions to prevent parts of the load from tipping or falling down. Prevent liquid loads from sloshing out.

• Electromagnetic influence can result in accidents Strong magnets can cause electronic components such as Hall sensors to become damaged, resulting in accidents.
•  Do not use magnets in the operating area of the truck.
• Risk of injury from falling parts
• Objects may fall if carried on the storage table.
•  Secure objects on the storage table against falling by using a container and/or fixtures.
•  Do not exceed the permissible load of the storage table.
• Loose objects may not be carried on the operator platform.

Two-hand operation
Only two-hand operation can trigger traveling, lifting and lowering movement.

 How to act in hazardous situations

• If the MEWP is in danger of tipping over or falling off a loading ramp, proceed as follows:
• Abandon the truck.

Avoid steering operations when traveling on a loading ramp.

 Emergency disconnect

• Maximum braking can cause accidents Operating the emergency switch during travel will bring the MEWP to a halt with maximum braking force, which can cause the load to slide. There is a higher risk of accidents and injury.
• Do not use the emergency switch as a service brake.
•  When traveling, only use the emergency switch in the event of danger.
• Faulty or non-accessible emergency switches can cause accidents In dangerous situations, the operator cannot bring the MEWP to a halt in time by applying the emergency switch.
•  Operation of the emergency switch must not be obstructed by objects placed in its way.
•  Report any defects on the emergency switch immediately to your supervisor.
• Identify the faulty MEWP and take out of service.
• Put into service only after the fault has been repaired.
  

Press the emergency switch (5). All main electrical functions are deactivated. The MEWP is braked to a halt. Turn the emergency switch (5) to unlock it. Enter the access code via the pin-code panel (7).

 Safety Regulations

Maintenance personnel
Batteries may only be charged, serviced or replaced by trained personnel. These operating instructions and the manufacturer’s instructions concerning batteries and charging stations must be observed when carrying out the work. Work on the battery, installation and removal must be performed only by service people.

Fire protection

Do not smoke and avoid naked flames when handling batteries. When the MEWP is parked for charging there must be no inflammable material or operating equipment that causes sparks within a distance of at least 2 m in the surrounding area. The room must be ventilated. Fire protection equipment must be available.

• The use of unsuitable fire-protection equipment can result in acid burns. In the event of fire, a reaction with the battery acid can occur if water is used to extinguish the fire, which may lead to acid burns.
•  Use powder extinguishers.
•  Never extinguish the burning batteries with water.
• Short circuits can result in fire. Damaged battery connections can cause short circuits which can then set fire to the MEWP and the battery.
•  Before closing the battery panel, make sure that the battery connections are not damaged.
•  Report any defects immediately to your supervisor.
•  Identify a faulty MEWP and take out of service.
•  Put the MEWP back into service only after the fault is identified and rectified.
