4 Maintenance
4.1 Cleaning
Before commencing any maintenance work disconnect the electrical power supply by pulling
out the plug!
Remove any oil and dirt from the shearing plant by means of a dry cloth. Do not use liquids!
4.2 Service
For safety reasons the portable shearing plant should be subjected to an annual inspection. It
is important that the self-tensioning belt is checked periodically, since the functionality of the
patented safety cutout device is dependent on this.
4.3 Lubrication
Lubricate the machine in accordance with the following specifications, since a lack of lubrica-
tion is the most common source of faults for unsatisfactory shearing results.
4.3.1 Shearing plant
Requires no lubrication.
4.3.2 Flexible drive
prior to each period of operation
Oil the flexible drive prior to use, and at least each time the cutters are replaced (Diag. 7,
pos. a).
after 100 hours of operation
The flexible drive is fitted with sealed and permanently lubricated ball bearings. The rotating
shaft bore must, however, be greased at regular intervals (after approximately 100 hours of
operation or every 2 years). To perform this task dismantle the flexible drive in order to remove
old grease residue from the shaft bore. Then re-lubricate the shaft bore along its whole length
with fresh, high-quality mineral grease.
4.3.3 Rigid drive downtube
The rigid drive downtube is fitted with sealed and permanently lubricated ball bearings. The
rotating cogs of the universal joint must, however, be lubricated at regular intervals during use
(approximately every 2 operating hours). Lubricate the shaft at the lubrication points provided
in accordance with Diag. 7, pos. b. Only high quality mineral oil is to be used for this purpose
(engine or gearbox oil).
