Troubleshooting

Whilst every measure has been undertaken by the manufacturer to ensure smooth reliable operation of the machine, sometimes problems can arise.

The following possible problems may arise:

1.The machine will not run.

Ensure power connected to machine is on. If ma chine still will not run, remove cover from control box and test for presence of power supply at top of left side contactor. If no power at contactors, test power supply at power source. If power supply is ok at source but there is no supply at contactors in con trol box, check connections inside accessory power point. These checks should only be performed by a licensed electrician)

2.The machine makes a low humming sound when switched to ON.

This indicates there are only two-phases of power supply at the motor. Switch off machine immediately to avoid motor burn-out. Have an electrician check the machine to determine the cause of the missing phase. If all three-phases are ok at motor then there is a strong possibility the motor is faulty.

3.The machine will only run in one direction. This indicates a problem with either the FWD/REV switch mechanism or one of the contactors. Have an electrician test the machine.

4.The machine will run but there is not power at the accessory power point.

Check connections inside accessory power point.

5.The machine does not have much suction.

(A)Inspect inside secondary filter housing

and make sure secondary filters are not blocked with dust. If blocked up with dust, remove and clean filters by either tapping out or using compressed air.

IMPORTANT!

A respirator should be worn at all times when performing filter cleaning activities.

If large amounts of dust present in secondary filter housing, this indicates a problem with the primary filters. Usually this means there is a hole in one or more of the primary filters or one of the primary filters has come loose.

Check primary filters for small holes or perforations. Small holes can be repaired/patched using silicone sealant.

(B)Make sure flap in bottom of collection cone is closing properly and creating a seal.

If this flap is not functioning properly, machine will tend to suck up dust bag when switched on.

6.The machine is blowing dust out the exhaust.

(A)Normally this means the secondary filters

are not installed properly and dust is bypassing them. Ensure the seals on the ends of the second ary filters opposite the secondary filter housing door are creating a proper seal. This can be viewed by looking down the filter link hose coupling.

(B) Secondary filters may need replacing.
