Inspection of brake lining
Open the inspection opening for checking the
brake lining thickness by folding the rubber tab
open.
The brake lining must be replaced when the bot-
tom edge of the wear pocket has been reached.
The residual lining thickness must be at least
2 mm.
Reinsert the rubber tab again after the check.
Brake adjustment
The function and wear of the brakes must be
checked continuously and adjusted, if this
should be necessary.
Resetting the brake is necessary, if approx. 2/3
of the max. cylinder stroke is utilized for flat-out
braking.
Adjustment work must be carried out by techni-
cal personnel of a workshop!

NOTE
The air reservoir must be drained daily!
Pull the drain valve (3) until water stops running
out from the air reservoir through the valve.
In case of contamination unscrew the drain
valve (3) from the air reservoir and clean the
air reservoir.
