SOLUTION SYSTEM
SOLUTION TANK REMOVAL
1 Drain both the solution and recovery tanks using the tanks’ drain hoses, then start machine and lower the scrub deck.
2 Remove the A1 control board Access Panel (A) and disconnect the solution float wire harness connector.
3 Swing open the recovery tank, separate the support strap, and disconnect tank full indicator wiring harness and lift tank off its hinge plate.
4 Remove the fuel tank. Investigate any special precautions in proper handling of the different fuel types (gasoline, LP and diesel fuel).
5 Remove the tail light panel secured by (3) Screws (B).
6 See Figure 1. Remove the (5) Hex HD Screws (C) that fastens the solution tank to the chassis.
7 Loosen the Hose Clamp (D) at the solution tank feed outlet fitting. Note: Remove the solution filter housing bowl to allow the needed access
for the clamp.
8 Lift the left rear corner of the solution tank and tilt tank towards operator side, then brace properly to support (may use tail light panel).
SOLUTION VALVE CONTROL CABLE REPLACEMENT
1 Drain the recovery tank then unlatch and swing it open to access the broom and solution cable inspection cover.
2 Remove the inspection cover held in place by (2) screws.
3 Remove the right side brush deck skirt assembly and also the squeegee tool.
4 Start engine and lower the brush deck, then turn the engine off. This is done to gain service clearance at the solution valve cable attachment
arm and mounting bracket.
5 Remove the cable ball joint end at the operator control handle bracket. Then loosen the cable casing anchor hardware and pull the cable
free from its slotted mounting bracket.
6 Remove the A1 controller Access Panel (A) (4 screws) located in the driver’s compartment below the solution lever.
7 Remove the A1 control box and relay bracket assembly to route the cable through the machine chassis.
8 From underneath the machine at the solution control valve arm remove its cable ball joint end. Next loosen the cable casing anchor hardware
and pull the cable free from its slotted mounting bracket.
9 Remove the (2) cable P-clamps (E) that fasten the cable casing to the machine frame.
10 Attach (wire or tape together) a new solution cable to the end of defective cable at the solution valve. Note: Remove all hex nuts and ball joint
end pieces from both the old and new cable to help reduce the overall diameter of the cable assembly for ease of installation.
11 Remove the cable by pulling on the original cable from the operator’s handle. Guide the old cable out and at the same time fish the new cable
up through the frame and control box opening and attach at the operator’s handle.
12 Reassemble all mounting hardware and adjust the cable’s anchor connector ends to obtain the correct On/Off solution handle movement.
TROUBLESHOOTING GUIDE
Problem Possible Cause
Inadequate or no solution flow No solution in the tank
Main solution flow control valve lever is in the off position
Clogged solution filter, valves, hoses
Defective solution solenoid valve (L16)
Solution system fault in the main controller A1*
*Reference the Main Control Board Troubleshooting Guide in the Electrical System of this manual for further information.
SOLUTION SYSTEM MAINTENANCE
• Solution Tank: See Figure 1. Weekly empty the solution tank; remove the solution Drain Hose (F) from its storage area (located underneath
the right side brush skirt frame). Direct the hose to a designated “Disposal Site” and flush the tank with clean water.
• Solution Filter: Important Service Tip You must first empty the solution tank (use drain hose) to prevent an uncontrollable loss of solution.
Then service (remove and clean) the inline Solution Housing (G). To access the filter housing for removal, work underneath the solution tank
(see solution system maintenance decal attached to chassis). No tools are needed to remove the filter (hand tighten only).
