MAINTENANCE

WARNING

For the protection of the environment; when servicing any of the machine’s lubrication ﬂ uids they must be disposed of safely in accordance with your local environmental regulations (recycling). Examples of machine lubrication products: (Hydraulic system oil, Hydraulic system oil ﬁ lter).

HOPPER DUST CONTROL FILTER

The hopper dust control ﬁ lter must be cleaned regularly to maintain the efﬁ ciency of the vacuum system. Follow the recommended ﬁ lter service intervals for the longest ﬁ lter life.

CAUTION!

Wear safety glasses when cleaning the ﬁ lter. Do not puncture the paper ﬁ lter. Clean the ﬁ lter in a well-ventilated area.

To remove the hopper dust control ﬁ lter...

1 Lift the Hopper Cover (16) on top of the hopper. Make

sure that the Hopper Cover Prop Rod (9) is in place.

2 Inspect the top of the Hopper Dust Control Filter (17)

for damage. A large amount of dust on top of the ﬁ lter is usually caused by a hole in the ﬁ lter or a damaged ﬁ lter gasket.

3 Turn the two hold-downs to the side (one on each

side at the front of the frame) to release the shaker frame, then swing the Dust Filter Shaker Assembly (18) up and latch in place with the Shaker Assembly Latch (19).

4 Lift the Hopper Dust Control Filter (17) out of the

machine.

5 Clean the ﬁ lter using one of the methods below: Method “A”

Vacuum loose dust from the ﬁ lter. Then gently tap

the ﬁ lter against a ﬂ at surface (with the dirty side down) to remove loose dust and dirt. NOTE: Take care not to damage the metal lip which extends past the gasket.

Method “B”

Vacuum loose dust from the ﬁ lter. Then blow

compressed air (maximum pressure 100 psi) into the clean side of the ﬁ lter (in the opposite direction of the airﬂ ow).

Method “C”

Vacuum loose dust from the ﬁ lter. Then soak the ﬁ lter

in warm water for 15 minutes, and then rinse it under a gentle stream of water (maximum pressure 40 psi). Let the ﬁ lter dry completely before putting it back into the machine.

6 Follow the instructions in reverse order to install the

ﬁ lter. If the gasket on the ﬁ lter is torn or missing, it must be replaced.

FIGURE 1

HYDRAULIC OIL

Raise and prop (HH) the hopper. See Figure 1. The oil level should be approximately 1 inch (2.54cm) below the bottom of the Elbow (A) on the front of the reservoir when the hopper is up (when the hopper is fully down the oil level should be up to the bottom of the elbow). If it is below this level, add 10W30 motor oil. Change the oil if major contamination from a mechanical failure occurs. SERVICE NOTE: The Cap (B) on Elbow (A) on the side of the reservoir is for adding oil. SERVICE

NOTE: Remove Vent Plug (D) to allow oil to be ﬁ lled.

IMPORTANT!

This machine is equipped with an Indicator Light (F) which lights if the Hydraulic Oil Filter (C / Figure 1) requires changing. The Hydraulic Filter (C / Figure 1) is found on the side of the Hydraulic Power Unit (27) as shown.

KNOW YOUR MACHINE

IMPORTANT SERVICE TIP

Before any troubleshooting is done perform this troubleshooting special control system procedure.

MAIN CONTROLLER (A1) SELF-DIAGNOSTIC TEST MODE

If problems with the main electronic control system are suspected, this self-diagnostic mode may help isolate the problem. When this mode is activated, the control unit will activate each one of the outputs in sequence and test for short circuits, open circuits, or overload conditions. This mode will also provide an easy test for the touch panel switches and indicators. If an abnormal condition is encountered with one of the outputs, an error code will be displayed on the Scrub Pressure Display (J) see Figure 2.

1 During this test, the horn will sound brieﬂ y and the scrub deck and squeegee will move if they are in the up position. If the hopper is not in the

down position it will also move slightly.

CAUTION!

Make sure that all persons are away from these parts of the machine to prevent injury.

2 Turn the main power key switch to the off position. 3 Press and hold the side broom down/on switch. 4 While holding the side broom down/on switch, turn the main power key switch to the on position. 5 Continue to hold the side broom down/on switch until all indicators except the side broom down/on indicator turn off (approximately two

seconds).

6 Release the side broom down/on switch. 7 The control will now activate each output in sequence and perform the tests mentioned above. 8 If no abnormal conditions are detected, the display will now show “-”. Go to step 10. 9 If abnormal output conditions were detected, the display will now show the error code(s), see “Main Control Error Code Display Descriptions

Table”. An example of how two codes, 6 and 18, would be displayed is as follows:

• The display will show “E” followed by a brief blank period

• The display will show “0” followed by a brief blank period

• The display will show “6” followed by a slightly longer blank period

• The display will show “E” followed by a brief blank period

• The display will show “1” followed by a brief blank period

• The display will show “8” followed by a long blank period

• The above sequence will repeat

10 To test any of the control panel switches, press the desired switch. The indicator for that switch should illuminate. If not, consult the general

machine troubleshooting section of this manual which will show machine system ﬂ ow charts.

11 The hopper limit, main broom, recovery tank full, and solution tank empty switches may also be tested in this mode. The corresponding

indicators will indicate the state of each of the inputs.

12 To exit this mode, turn the main power key switch to the off position.

NOTE: If the machine is not equipped with an optional back-up alarm, an error code 59 will be indicated.
