Notice Noise indications: The figures given are emission levels and not necessarily safe working levels. Although there is a relationship between the level of noise emission and the level of noise exposure, it cannot be used reliably to determine whether further protective measures are necessary or not. Factors influencing the actual level of exposure of workers include the characteristics of the workspace, other sources of noise, etc., i.e. the number of machines and other nearby processes and the length of time an operator is exposed to noise. In addition, the permissible exposure level may vary from country to country. However, this information should allow the user of the machine to better assess the hazards and risks.

GUARANTEE TERMS

1.) Warranty:
For mechanical and electrical components Company Holzmann Maschinen GmbH garants a warranty period of 2 years for DIY use and a warranty period of 1 year for  professional/industrial use – starting with the purchase of the final consumer (invoice date).
In case of defects during this period which are not excluded by paragraph 3, Holzmann will repair or replace the machine at its own discretion.

2.) Report:
In order to check the legitimacy of warranty claims, the final consumer must contact his dealer. The dealer has to report in written form the occurred defect to Holzmann. If  the warranty claim is legitimate, Holzmann will pick up the defective machine from the dealer. Returned shippings by dealers which have not been coordinated with  Holzmann will not be accepted. A RMA number is an absolute must-have for us – we won‘t accept returned goods without an RMA number!

3.) Regulations:
a) Warranty claims will only be accepted when a copy of the original invoice or cash voucher from the trading partner of Holzmann is enclosed to the machine. The warranty  claim expires if the accessories belonging to the machine are missing.
b) The warranty does not include free checking, maintenance, inspection or service works on the machine. Defects due to incorrect usage through the final consumer or his dealer will not be accepted as warranty claims either.
c) Excluded are defects on wearing parts such as carbon brushes, fangers, knives, rollers, cutting plates, cutting devices, guides, couplings, seals, impellers, blades, hydraulic  oils, oil filters, sliding jaws, switches, belts, etc.
d) Also excluded are damages on the machine caused by incorrect or inappropriate usage, if it was used for a purpose which the machine is not supposed to, ignoring the user  manual, force majeure, repairs or technical manipulations by not authorized workshops or by the customer himself, usage of non-original Holzmann spare parts or  accessories.
e) After inspection by our qualified staff, resulted costs (like freight charges) and expenses for not legitimated warranty claims will be charged to the final customer or dealer.
f) In case of defective machines outside the warranty period, we will only repair after advance payment or dealer’s invoice according to the cost estimate (incl. freight costs) of  Holzmann.
g) Warranty claims can only be granted for customers of an authorized Holzmann dealer who directly purchased the machine from Holzmann. These claims are not transferable in case of multiple sales of the machine.

4.) Claims for compensation and other liabilities:
The liability of company Holzmann is limited to the value of goods in all cases.
