Make sure you raise the brush deck before driving to the cleaning site.
Safety Gloves are recommended for the changing of used brushes.
Floor Tool Transit Bracket
When in transit, the floor tool can be placed on the bracket at the rear of the machine.
Simply slot the retaining knob into the bracket.
Filling the Clean Water Tank
The TGB 2120/2128 is equipped with a large capacity 80 litre clean water tank, allowing for large areas to be covered in a single fill.NACECARE SOLUTIONS
TGB2128 Ride On Scrubber Dryer - assembly 11 Note: Great care must be taken to ensure that contaminants (leaves, hair, dirt, etc.) are not allowed to enter the clean water tank during the filling process. If using a bucket or similar, ensure it is always clean and free from debris.

Fill Level Indicator
When filling the clean water tank, do not fill above the clean water tank emptying hose retaining clip.
This can be found at the rear of the machine.NACECARE SOLUTIONS TGB2128 Ride
On Scrubber Dryer - assembly 12 If you need to access the batteries, make sure that the waste water tank is empty before lifting.

Machine Operation

IMPORTANT
Do not operate machine unless the operator manual has been read and fully understood.
Drive the machine to the cleaning site (read set-up guide again if necessary – page 5).
Before cleaning operation, place out appropriate warning signs and sweep or dust-mop the floor.
When ready for cleaning lower the floor tool (page 6) and the brush deck (page 7).
Setting the Cleaning ControlsNACECARE SOLUTIONS TGB2128 Ride On
Scrubber Dryer - assembly 13 Waste Water Tank Full
The vac shut off system stops the airflow when the top waste water tank is full.
The vac motor will continue to run, there is an audible difference in the sound when the shut off system operates.
For more details on checking and cleaning the shut off system see page 13.NACECARE SOLUTIONS TGB2128 Ride On Scrubber Dryer - assembly
14 Always ensure that the floor is pre- swept and relevant safety signs are displayed.
Emergency Stop Button / HornNACECARE SOLUTIONS TGB2128 Ride On Scrubber
Dryer - assembly 15 Note: After the Emergency Stop button has been pressed the Traction LED will flash 7 times, pause and repeat until the Emergency Stop button has been reset and the machine switched off / on.

Maximum Speed Control
Set desired traction speed as required, depending on floor type and level of soiling.
NACECARE SOLUTIONS TGB2128 Ride On Scrubber Dryer - assembly
16Once the Max speed has been set using the control knob on the control panel, fine adjustments can be made using the variable control speed pedal located on the right side of the footplate.
Care must be taken to reduce speed when cornering or manoeuvring.

Anti-tip System
The CRG 8055/8072 is equipped with an Anti-tip system.
The machine automatically slows down preventing the machine from tipping over if cornering at speed.
NACECARE SOLUTIONS TGB2128 Ride On Scrubber Dryer - assembly
17The buffers at the front are designed to prevent the machine tipping in the event of the operator turning sharply.
The buffers are designed to be replaceable when worn.
Do not operate the machine on inclines that exceed 11%.

Machine in Use
To operate, select forward and depress the accelerator pedal.
Note: The machine will not operate in reverse with the floor tool lowered.
Vacuum pick-up and water flow will turn on if selected, and providing the brush and floor tool are in the lowered position, the machine will move forward.
Clean water is dispersed evenly via ‘THRU- FEED’ scrubbing brushes.
NACECARE SOLUTIONS TGB2128 Ride On Scrubber Dryer - assembly
18The waste water is then retrieved by the suction floor tool.
Overlap each scrubbing path by 10cm to ensure an even clean.
After stopping, let the vacuum motor run for 10 seconds to collect any water left in the vacuum hose, then switch the vacuum motor off.
On heavily soiled floors use a ‘double scrub’ technique.
First pre-scrub the floor with the floor tool in the raised position, allow the chemicals time to work, then scrub the area a second time with the floor tool lowered.
If your machine leaves streaks on the cleaned floor, either clean the floor tool blade or adjust blade height for optimum performance.NACECARE SOLUTIONS
TGB2128 Ride On Scrubber Dryer - assembly 19 Off-aisle Cleaning Kit (Optional Extra Accessory) 606182
The optional off-aisle cleaning kit gives added flexibility to the operator.
The kit can be used to clean hard to reach / inaccessible areas.
Remove the vacuum hose from the floor tool and attach to the off-aisle kit.
To operate the vacuum, press the vacuum switch on.NACECARE SOLUTIONS
TGB2128 Ride On Scrubber Dryer - assembly 21 Note: Return the hose to the floor tool once finished using the off-aisle facility.NACECARE SOLUTIONS TGB2128 Ride On Scrubber Dryer -

Machine Cleaning

Always ensure that the machine is switched off prior to any maintenance.NACECARE SOLUTIONS TGB2128 Ride On Scrubber Dryer - assembly
22 A After use, empty waste water tank using emptying hose and flush-out with clean water.
B Remove floor tool vacuum hose ensuring you remove the U-bend clip and flush out with clean water.
C Empty clean water tank, using emptying hose and again flush out with clean water.
NACECARE SOLUTIONS TGB2128 Ride On Scrubber Dryer - assembly
23 Note: The separator can be hung from either side of the top tank while you maintain the machine using the clip on the front of the lid.
When refitting the separator make sure you engage the front of the separator BEFORE pushing the separator down.
Refit the vacuum hose.
Located in your waste water top tank is a vacuum shut off system, this prevents suction when the waste water tank is full. It also prevents foam created by high-foaming detergents from entering the motor. Sometimes the float vents get clogged and blocked, clean to ensure correct operation. Regularly check and clean the air filter in the top of the assembly. Remove debris basket filter and rinse using clean water, and refit.
IMPORTANT: If the debris basket is allowed to become clogged, vacuum performance can deteriorate.NACECARE SOLUTIONS TGB2128 Ride On Scrubber
Dryer - assembly 24The clean water tank filter is located to the front of the battery compartment, and should be checked at regular intervals.
Lift the filter off of the cradle, unscrew the bottom and remove, taking care not to spill any liquid on to the batteries.
Rinse using clean water and refit, refitting is reversal of removal.
Note: Any Spills should be wiped up before tank is lowered.NACECARE

Free Wheel Function

ALWAYS ENSURE THAT THE MACHINE IS ON LEVEL GROUND BEFORE DISENGAGING BRAKE ARM.
NEVER DISENGAGE THE BRAKE WHEN THE MACHINE IS ON A SLOPE / GRADIENT.

The TGB 2120/2128 is equippe d with a free wheel function that will enable the operator to move the machine.
The free wheel lever can be found on the right hand side of the rear axle.
NACECARE SOLUTIONS TGB2128 Ride On Scrubber Dryer - assembly
26To disengage the brake, pull the lever into the down position.
Re-engage the brake by moving the lever into the up position.
Note: When the brake is disengaged the machine has no braking facility.
Care must be taken when moving the machine in free wheel mode.

Changing the Floor Tool Blades

Always ensure that the machine is switched off prior to any maintenance.
Lower the floor tool then unscrew the retaining knobs and slide it off the holding bracket.
Rinse the floor tool assembly with clean water and refit.NACECARE SOLUTIONS
TGB2128 Ride On Scrubber Dryer - assembly 27Periodically the floor tool blades should be examined and checked for wear and damage.
Replacement is a reversal of the removal process.
