10. Maintenance
Before maintenance work is carried out, disconnect the
machine from the supply lines and make sure that it
cannot be switched on again accidentally.
The Health and Safety at Work (UVV) regulations
applicable must be observed for maintenance work.
Basically, the tyre changer requires no particular
maintenance.
The reduction unit is for-life lubricated and so does
not require maintenance.
Maintenance work which must be carried out at
regular intervals to ensure proper and fault-free
operation is listed below:
• Clean the machine daily. Remove dirt from the
clamping jaw guides and lubricate the guides.
• Check the oil level in lubricator every 2 or 3 days.
The oil level in the lubricator (Fig. 31) must never
drop below the suction pipe.
Only oil with a viscosity of 2.5 °- 7° (16 - 55 cST)
at 50°C must be used for topping up (for oils
allowed see label on machine). After topping up,
always adjust the lubricator as follows.
• Check oil dosage: After operating the pedals (6
and 8, Fig. 31) 2 - 3 times, one drop of oil should
fall into the sight glass. If necessary adjust using
the dosing screw (1, Fig. 31).
• Regularly drain the condensation from the fi lter
collector (3, Fig. 31). To do so, turn the locking
ring (4, Fig. 31) anti-clockwise.
• Once a month, disconnect the machine from the
compressed air network (2, Fig. 31) and clean the
fi lter condensation collector (3, Fig. 31).
• At least once a year clean the worst of the dirt
from the bearings, guides and the like and keep
them running smoothly.
• At least once a year lubricate with a commercial
lubricant.
• Whenever necessary, clean the lubricator level
tube only with water, petroleum or spirit (not
petrol for use in cars!).
10.1 Troubleshooting
Before any repair work is carried out, disconnect
the machine from the supply lines and make sure
that it cannot be switched on again accidentally.
During repair work, the Health and Safety at Work
(UVV) regulations applicable must be observed.
If faults occur which cannot be eliminated by the
operator, call the after-sales service.
