9 Maintenance
Cleaning
• The steel undercarriage can be cleaned with a damp cloth and a (nonabrasive) liquid household
cleaner
Maintenance
• To keep the leather parts flexible, you can use leather fat.
• After some time, the sliding and turning parts could run less smoothly, because of pollution and
dehydration. You can re-grease the Pulley with ball bearings grease (which you can obtain at a
bicycle shop). If required, the guiding bars of the weights can be greased with a little oil.
• Check the cord and the cord fixations regularly for signs of wear. In case of excessive wear and
tear, the cord must be replaced and use of the EN-Tree Pulley is not recommended until the cord
has been replaced.
• In order to obtain spare parts, please contact your supplier.
• We recommend to have the EN-Tree Pulley checked yearly by authorized personnel of Enraf-
Nonius or by its authorized distributor. The manufacturer will not be held responsible for the
results of maintenance or repairs by unauthorized persons!
