WARNING
Unplug the machine from the socket and make
sure that all moving parts have been locked
before
performing any adjustment or maintenance
operation.
WARNING
Do not remove or modify any part of the machine
(except for service interventions).
CAUTION
Keep the work area clean.
Never use compressed air and/or jets of water to
remove dirt or residues from the machine. Take
all possible measures to prevent dust from
building up or rising during cleaning operations.
Keep the wheel balancer shaft, the securing ring
nut, the centering cones and flange clean. These
components can be cleaned using a brush
previously dripped in environmentally friendly
solvents. Handle cones and flanges carefully so
as to avoid accidental dropping and subsequent
damage that would affect centering accuracy.
After use, store cones and flanges in a place
where they are suitably protected from dust and
dirt. If necessary, use ethyl alcohol to clean the
display panel. Perform the calibration procedure
at least once every six months.
LUBRICATION
The only rotating parts of the wheel balancer are
the motor and balance shaft. These parts must be
periodically lubricated by the operators. If the
machine is used very frequently, more than
2hours per day, we should annually check the
bearing. And we will check once a year if the
machine is used less than 2hours a day. When
test, do not open up the bearing so you need
insert a screwdriver to test the noise. Due to the
function of the bearing is to clamp and support
and not suitable to change or remove the grease.
In addition, the speed of it is not too fast
compared to the machine so no need to change
the grease. If you note the run of the bearing
abnormal or there is noise, change the bearing. If
the customer confirms the bearing is not changed,
you only need change the grease. Disassemble
the bearing and open up the sealing ring and fill
the XHP103 grease. These operation should be
guided by the profession personnel and calibrate
the machine after changing the grease. If the
change of the grease not correctly, it will
influence the accuracy of the machine. On this
condition, you need to reinstall the sealing ring
and assemble the machine and adjust again.
