To ensure stability and central location of the penetration piston, the stability bar must
always be used. When using the maximum number of surcharge weights, it may be
necessary to clamp the stabilising bar to the threaded part of the columns. In this
case it is recommended that packing pieces (i.e. aluminium strips) be placed between
the stabilising bar clamp screws and the column threads to prevent damage to the
column threads.
6.7
Do not use the machine with the platen unscrewed by more than 70 mm (rapid
adjustment).
6.8
Switch the machine on using the ON/OFF switch at the rear of the machine (POWER
light illuminated).
6.9
Switch the machine to UP (Up arrow illuminated).
6.10
At the end of the test, switch to central OFF position and allow the motor to stop.

Important: ensure that the motor has stopped before reversing platen direction.
This may take approximately 5 seconds. Failure to allow the motor to stop
when changing platen direction may cause severe damage to the machine.
