Adjustment and setup work
ZSM 560 | Version 1.01 17
13.3 Adjustment of the pressure roller
The height of the pressure rollers is set below the grin-
ding drum to hold the workpiece firmly against the feed
belt as it passes through the grinder and to prevent the
workpiece from kicking back.
Fig. 19: Pressure rollers
The pressure that the pressure rollers exert on the work-
piece while the workpiece is being machined is control-
led by pressure springs and adjusting screws.

The correct pressure on the workpiece helps to prevent
kickback. However, if the pressure on the workpiece
from the rear pressure roller increases, the pressure on
the grinding drum also increases. In this case, reduce
the pressure on the rear pressure roller.
If you want to increase or decrease the pressure that
these rollers exert on the workpiece, perform the follo-
wing steps.
Step 1: Switch off the machine and disconnect the power
plug.
Step 2: Loosen the locking hook of the cover below the
handle.
Step 3: Swing the cover up to include access to the pres-
sure roller adjustment screws.
Step 4: To increase the pressure exerted by the rollers,
tighten all four screws in small, even turns and
test the pressure of the rollers by pushing them
upward. Conversely, loosen the adjustment
screws to decrease the pressure.
Step 5: Perform test run. If the workpiece tends to recoil,
decrease the pressure by turning the screws
counterclockwise.
Step 6: If the workpiece slips on the belt, increase the
pressure by turning the screws clockwise one
turn and perform the test again.
13.4 Setting the height stop
The adjustment screw, which protrudes through the bot-
tom of the frame, serves as a stop to prevent the grinding
drum from coming into contact with the feed belt when
adjusting the height.
Fig. 21: Height stop adjustment screw
The setting of the screw was set correctly at the factory.
However, if it is necessary to readjust the stop screw, per-
form the following steps.
Step 1: Switch off the machine and disconnect the power
plug.
Step 2: Make sure that the belt is correctly tensioned.
Step 3: Crank the grinding drum to the highest position.
Step 4: Loosen the hex nut on the adjustment screw and
adjust the height of the screw that protrudes
above the frame so that it protrudes no less
than 6.3 mm.
