Maintenance
Regular maintenance is a basic requirement for the
continued safe and efficient use of the machine.
Follow the maintenance instructions carefully.
♦
Before starting maintenance on the machine, clean
it in order to avoid exposure to hazardous
substances. See “Dust and fume hazard”.
♦
Use only authorised parts. Any damage or
malfunction caused by the use of unauthorised
parts is not covered by warranty or product liability.
♦
When cleaning mechanical parts with solvent,
comply with appropriate health and safety
regulations and ensure there is satisfactory
ventilation.
♦
For major service of the machine, contact the
nearest authorised workshop.
♦
After each service, check that the machine's
vibration level is normal. If not, contact the nearest
authorised workshop.
Every 10 hours of operation
(daily)
Maintenance routines:
♦
Check and clean the motor's cooling flanges. Sand
and stones could clog the air inlet and reduce the
cooling of the drive unit.
♦
Clean the machine. After every working shift
concrete splashes must be removed from the
surfaces while it is still fresh.
♦
Check that the controls are not damaged and do
not jam. Replace if necessary.
NOTICE
Never use high-pressure water to clean
the drive unit.
Every 75 hours of operation (or
every second week)
Maintenance routines:
♦
Disconnect the flexible shaft from the drive unit by
lifting the locking mechanism. Unscrew the shaft
from the poker which is a left-handed thread.
♦
Pull out and lubricate the inner shaft with SHELL
HDX2 RETINAX grease or equivalent. About 20
grams of grease is required per meter of the shaft.
NOTICE
Do not grease the inner shafts too
extensively. Greasing too much can cause overload
of the electric drive unit and trip the circuit breaker.
Run the unit for two minutes continuously to distribute
the grease in the flexible shaft before immersion in
the concrete.
Every 100 hours of operation
(or monthly)
Maintenance routines:
♦
Inspect the carbon brushes on a monthly basis or
every 100 hours. At normal duty the carbon
brushes would last for approximately 250 hours
but premature wear can occur depending on the
working conditions or intensive use.
♦
Inspect the commutator and the carbon brushes.
If the commutator is worn, it can be turned down
in a lathe. The minimum diameter is 35.5 mm (13.9
in.).
Changing the carbon brushes
The machine is equipped with two carbon brushes
that are placed on each side. The carbon brushes
are machined to ensure a good contact between the
commutator and the carbon brush. The carbon
brushes are equipped with a safety system which
stops the motor when there is significant brush wear.
The carbons are located on each side of the drive
unit. When carrying out the work, systematically
replace both carbon brushes.
Note:
There are two models of carbon brushes, both
models are perfectly compatible.
