Inflating
If the turntable stops during mounting due to excessive
bead tension, stop the procedure, turn the turntable
back slightly, press the part of the bead already
mounted down into the rim, if necessary using a bead
pusher, then continue mounting. With easily mountable
tyres and/or a skilled operator, mounting is possible
without interruptions.
One or two optionally available bead pushers (1, Fig.
21) or the pneumatic mounting tool (2, Fig. 21) can be
used to hold the tyre still during mounting.
9. Inflating a tire
For safety reasons, wear safety goggles and ear plugs
when inflating a tire, particularly when using inflating
devices with air jets.
When inflating a tire always follow WdK and applicable
national guidelines and relevant safety standards to
avoid most personal injuries and material damage.
The inflating pressure must not exceed the tire
C
operating pressure by more than 50% (recommended
by WdK, German rubber industry economic
association). Seating pressure should not exceed 3.3
bar. The final pressure must not exceed 3.5 bar.
9.1 General information about tire inflating devices
For use in Germany, tire inflating devices (Fig. 22-26) are
subject to German law with respect to calibration (Official
Journal - Measuring and calibration system law of 11 July
1969, paragraph one, No. 2, section 3).
Pressure gauge calibration lasts for two years after the end
of the calendar year in which the equipment was last
calibrated. For calibration in accordance with German
regulations, the year until which the equipment is considered
calibrated is specified and/or for EC calibration, the date
when the equipment was calibrated is stated.
The operator is responsible for any recalibration. When
calibration has to be repeated, the equipment user must
request calibration at the relevant office.
For safety reasons a quick-inflating valve preset to 3.5 bar
is fitted upstream of the pressure gauge for the pedal-
operated inflating device, guaranteeing that the maximum
inflating pressure does not exceed 3.5 bar. All valve
switching operations during inflation are clearly audible as
a clicking noise, therefore this is not a malfunction.
If wheels require a higher pressure, they have to be inflated
using a special inflation station equipped with safety devices
(such as a safety cage, retaining means and the like).
