2. General Safety Instructions 2.1 Duties of the owner-operator Follow national accident prevention regulations and all operator health and safety at work and operating regulations. The balance may only be used for the proposed purpose. Any type of use which is not specified in these operating instructions, will be considered as improper use. The customer is solely responsible for material damage and injury of persons resulting from an improper use, Messrs.
2.4 Pay attention to the instructions in the Operation Manual Carefully read this operation manual before setup and commissioning, even if you are already familiar with KERN balances. All language versions contain a non-binding translation. The original German is binding. 2.5 Proper use The balance you purchased is intended to determine the weighing value of material to be weighed. It is intended to be used as a “non-automatic“ balance, i.e.
2.8 Safe working Do not stand under swinging loads, see chap. 5.1. Position the crane in a way that the load is lifted vertically. When working with the crane and suspended balance wear personal safety equipment (helmet, safety shoes etc.). 2.9 Monitoring of Test Resources In the framework of quality assurance the measuring-related properties of the balance and, if applicable, the testing weight, must be checked regularly.

3.2 Overview visual displays and keyboard Displays: kg The current measuring unit is kilogram lb The current measuring unit is pound N The current measuring unit is Newton LO E Indicates the weight value depending on the active setting H1-H6 (see chap. 5.7).
3.3 Label Do not stand or go under suspended loads. Do not use on building site. Keep an eye on suspended loads. Do not exceed nominal rated load of balance. (example) The product conforms to the requirements of the German Equipment and Product Safety Act.
4. Commissioning + 4.1 Always observe chapter 2 „General Safety Instructions“! Unpacking Once delivered and unpacked, suspended balance will not be taken back. The suspended balance is sealed by KERN. SAFETY INSTRUCTIONS for protection against Removal from packaging is also sealed. + Broken seal obliges to purchase. break Fig.: Seal Thanks for your comprehension. Your KERN Quality assurance team 4.2 Scope of delivery Remove balance and accessories from packaging, remove packaging material.
4.3 Checking the original dimensions Enter the original dimensions shown on the production data sheet in the grey boxes of checklist chap. 8.3. Check original dimension of suspended balance; for implementation see chap. 8.3 „Regular Maintenance“ Enter all data (date, tester, results) in the first line under „Inspection before first use“ in the checklist (see chapter 8.3) CAUTION 4.
5. Operation Keep balance only by hand, see fig. (do not use a crane or alike). 5.
Take great care when operating the crane and follow the general rules for crane operation. Check all parts (hooks etc.) for excessive wear or damage Work only with appropriate speed Always avoid vibrations and horizontal forces. Avoid any kind of shock, torsion and oscillating (e.g. caused by inclined suspending) Do not use the suspended balance for conveying loads. Do not stand or go under suspended loads. Do not use on building site. Keep an eye on suspended loads.
5.2 Loading the suspended balance For good weighing results observe the following, illustrations see next page: Do not suspend the balance on load attachment devices. Use only when keeping by hand. Do not pull or push the load or the loaded balance. Do not pull the hook horizontally. Loading the balance 1. Position the hook of the suspended balance over the load. 2. Suspend and lift the load.
Keep balance only by hand! Do not push or pull Do not pull the hook horizontally HDB-N-BA-e-1320 17
5.3 Turn on/off Start-up Press the ON/OFF button. The display lights up and the balance carries out a selftest. The selftest is completed when the weight value 0 appears on the display. Switching Off Press the ON/OFF button for a long time. 5.4 Taring Suspend preload. Press the TARE button, the zero display disappears. The weight of the container is now internally saved. Weigh the material, the net weight will be indicated. After removing the preload weight appears as negative display.
5.6 Switch-over weighing unit The next measuring unit will be displayed kg lbN after each press of the UNIT button. The indicator shows the active unit. 5.7 Functions With help of the Hold-button the following functions can be activated: Adjustment Function H1 Data-Hold function 1 Weighing value frozen for 5 sec.
5.7.1 Data-Hold function Switch on the balance, keep the HOLD-button pressed until the current setting „Hx“ (H1 – H6) appears. Press ON/OFF button repeatedly until the desired setting „H1-H4“ is displayed. Confirm setting with the HOLD button. Suspend the material to be weighed The weight value is fixed and displayed depending on the setting (H1 – H4) (see chap. 5.7), represented by the [] in the upper left. 5.7.2 Animal weighing function This function is suitable for busy weighing procedures.
5.7.3 Peak value function This function displays the highest load value (peak value) of a weighing. Measuring frequency: 200ms Attention: Never exceed the maximum permitted load of the peak value on the balance (!!Danger of breaking!!). Switch on the balance, keep the HOLD-button pressed until the current setting „Hx“ (H1 – H6) appears. Press ON/OFF button repeatedly until the setting „H6“ is displayed.
7. Adjustment As the acceleration value due to gravity is not the same at every location on earth, each balance must be coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration due to gravity at its place of location (only if the balance has not already been adjusted to the location in the factory). This adjustment process must be carried out for the first commissioning, after each change of location as well as in case of fluctuating environment temperature.
8. Cleaning, Maintenance and Disposal Risk of injury and risk of material damage! The suspended balance is part of the lifting gear! For a safe operation please observe the following: Danger 8.1 Have carried out a regular maintenance by trained specialized staff Carry out regular maintenance and servicing, see chap. 8.3. Have the parts exchanged only by trained specialized staff. If there arose discrepancies with the safety checklist, the balance must not more be put into operation.
8.2 Regular maintenance and care The regular 3-month maintenance may only be carried out by an expert with competent knowledge of working with suspended balances. Thereby the national regulations for prevention of accidents as well as the working, operation and safety regulations of the owner-operator. To check the dimensions only use suitable test devices. The regular 12-month maintenance must only be carried out by trained specialized staff (KERN customer service).
Regular maintenance: Prior to each usage Check for fault-free operation of the attachment devices Initial start-up, every 3 months or definitely after 12 500 weighing processes Check all dimensions, see checklist chap. 8.3 Check the attachment device for wear and tear, such as e.g. plastic deformation, mechanical damage (unevenness), notches, striation, cracks, corrosion, thread damage and torsions.
