If JDN Air Hoists are operated without a
chain box it must be ensured that the idle
chain (unloaded chain end) running up or
down at the chain sprocket, does not present
a hazard, e.g. due to catching, impacting or
falling. 

Danger due to falling chain can also arise, if
the idle chain is first deposited on a load
with a large surface and then slides off and
drops.

JDN air hoists are provided with motor lubrication, 
which must be renewed when required, but every 
5 years at the latest. 
Therefore, the service unit for filtration and pressure
regulation of the compressed air can be installed 
without an oiler. If required, the service unit is also
available with an oiler. Synthetic lubricants must not 
be used when operating with a service unit. Alcohols 
are not permitted for use as anti-icing agents.

Only hoists for which EC conformity in accordance with
EC Machinery Directive 2006/42/EC has been declared
may be operated within the EU.

In the case of a 

designation, only the EC conformity

declaration provides information on which EC directive
has been met.

Only use 

original JDN spare parts
