BRUSH MOTOR ELECTRICAL INPUT CHECK [RAZOR SV 17]
1. Check that the brush (A) is installed on the machine.
2. Drive the machine on a level ground.
3. Check that the switches (5 and 6) are turned to “0”.
4. If there is recovery water in the tank (43), drain it through the hose (22).
5. Disconnect the vacuum hose (29) from the squeegee (17).
6. Open the cover (12).
7. Grasp the recovery water tank (A) in the area (B) and lift it, as shown in the figure, then disconnect the vacuum hose (C)
from the tank and remove the tank (A) together with the hoses (D) and (E).
8. Set an ammeter (F) on the battery supply cable (red) (G) of the brush motor (H). Adjust the full-scale at 50 A or more.
9. Activate the brush by turning the switch (5) to “I”, then check that the brush motor electrical input is within the following
limits:
–
with the brush on floor tiles: 8 to 10 A
– with lifted brush: 2,7 to 3,2 A
Turn the switch (5) to “0”.
If the electrical input is higher, perform the following procedures to detect and eliminate the cause of the abnormal input:
–
Remove from the brush rotation shaft/flange all the possible amounts of dirt or wrapped-round materials (ropes,
clothes, etc.), which prevent or slow down its rotation;
– If necessary, check the motor carbon brushes;
– If necessary, disassemble the motor, clean it and check its moving parts.
If the above-mentioned procedures do not lead to a correct electrical input, the motor must be replaced.
10. Carry out steps from 5 to 8 in the reverse order.
