1.1. Principle of Intended Use

The manufacturer and supplier assume no liability for incorrect or non-intended use. Any change made to the

device that is not performed by the manufacturer is forbidden. Changes made by attachments or conversions are

only to be performed with the written consent of the manufacturer.

The device is built according to the state of the art and the recognised safety-technical rules. Nevertheless,

dangers to life and limb of the user or third parties or impairment of the device and other property may occur when

using the device.

Use the device only in a technically impeccable condition as well as in the intended manner, safety- and danger-

consciously. Use under observation of the operating instructions!

Specifically remove interferences that may impair safety (have them removed)!

The LISSMAC stone grippers belong to the device class of the hand-held gripping tools and serve solely to move

bricks in connection with a suitable and tested load holder. For hand-guided movement, the control is firmly

installed to the stone gripper and must only be operated by one operator. The maximum carrying capacity of the

stone gripper must not be exceeded.

Any other or exceeding use is deemed non-intended.

Intended use also includes observation of the operating instructions and compliance with the inspection and

maintenance instructions.

Foreseeable misapplication/non-intended use:

 Lifting damaged and contaminated bricks

 Lifting bricks with iced adhesive faces

 Lifting bricks with worn carbide tips

1.2. Organisational Measures

Always keep the operating instructions readily accessible to any person at the site of use.

Observe and order supplementations of the operating instructions, such as general legal and other binding rules

for accident prevention and environmental protection!

Such obligations may also include, e.g., handling of hazardous substances or wearing of personal protection

equipment or rules on road-traffic.

The staff charged with activities must have read and understood the operating instructions and specifically the

chapter Safety Notes, before taking up work. During work it will be too late. This specifically applies to staff only

working at the machine occasionally, e.g. when equipping, servicing.

At least occasionally check for safety- and danger-conscious work of the staff under observation of the operating

instructions!

Where required or demanded by provisions, wear personal protection.

Observe all safety and danger notes.

Keep all safety and danger notes completely legible.

In case of any safety-relevant changes of the operating conduct, shut down the device at once and mark it

accordingly. Report interference to the relevant office/person.

Do not perform any changes by attachments and conversions without the written consent of the manufacturer.

10/35

Only use tested and genuine spare parts of the manufacturer.

Comply with periods prescribed or indicated in the operating instructions for inspections! An inspection by an

expert (TÜV or manufacturer) is prescribed every year.

Annual inspections must be performed on the stone gripper. They must be recorded in writing in these operating

instructions.

The device must be thoroughly cleaned before the inspection.

1.3. Selection and Qualification of Staff; General Obligations

Only persons who have completed the 18th year of life must be charged with independent operation. All persons

must have been instructed in operation of the stone gripper and expressly charged with operation by the owner.

The operator must have personal safety equipment such as safety shoes, safety gloves and a construction helmet

that comply with the safety provisions.

Unnecessary staying in the movement and working range is prohibited! If required, lock the working area.

The operator must ensure during all movements that he does not endanger himself and other persons.

Staff to be trained, taught or instructed or in the scope of general training must only work at the device

consistently monitored by an experienced person!

1.4. Safety Notes on the Operating Phases

1.4.1. Transport, Assembly and Installation

The stone gripper must be disassembled during transport.

Check load handling for damage before installation of the stone gripper.

Observe the maximum load-bearing capacity of the stone gripper.

The gripping jaws installed at the stone gripper must be approved for the brick.

At least once a year, check the stone gripper for outwardly visible damage.

Check carbide tips with the measuring template before operation!

11/35

1.4.2. Operation

Do not perform any work that poses a concern for safety!

Take measures so that the stone gripper is only operated in a safe and functional condition!

At a wind strength in excess of wind level 7 (15 m/sec.) or approaching storm, the stone gripper must be set up at

once and secured against lighting strike.

Transporting different working material such as bricks and other tools is prohibited!

The maximum carrying capacity of the stone gripper must not be exceeded.

No persons must be present under suspended loads.

To protect from acceleration of the load, the load must be moved clear slowly.

1.4.3. Special Work in the Scope of Use of the Machine

Setting, warning and inspection work must be performed according to these operating instructions, including

information on the exchange of parts/partial equipment! This work must only be performed by authorised

specialists.

Before cleaning the stone gripper, the control must be disassembled.

Always tighten any screw connections loosened during service and repair work!

1.5. Transport

The stone gripper must be disassembled during transport before load handling.

Proceed only according to the operating instructions at recommissioning!

1.6. Packaging and Storage

The device was packed carefully to warrant sufficient protection during shipping. Check the device for damage upon

receipt.

The device must not be taken into operation in case of damage.

In this case, inform LISSMAC Maschinenbau GmbH.

If the device is not taken into operation at once after unpacking, it must be protected from moisture and dirt.

12/35

1.7. Environmental Protection

Packaging material, cleaning agents, used or residual operating media as well as unpacked wear parts such as drive

lets or motor oils must be supplied to recycling according to the environmental protection provisions applicable at

the site of use.

1.8. Disposal

The device's packaging consists of recyclable materials. Put them into the intended collection container sorted by

type so that they can be supplied to reuse.
